Conclusion 4 Chapter 1 Introduction Purpose The purpose of this document is to establish the various risks within the City of Pueblo and the surrounding areas that the Pueblo Fire Department responds to. This document will attempt to list, in detail, each specific risk and the response strategy that we will employ when faced by these risks. It will also outline manpower, equipment, and training needs for each risk category. History The Pueblo Fire Department exists to provide a high level of firefighting and emergency response services to the residents of the City of Pueblo. The department, with over 120 years of rich history, currently has 140 highly trained men and women that make up the operational forces. There are 7 members of the staff and administration that lead and support the operational personnel. The department was the third fire department in the United States to unionize and was awarded CFAI accreditation under Fire Chief Christopher P. Riley in August 2008. The department responded to 17,035 calls for service in 2012. There were 11,769 calls for emergency medical care or about 69% of the total calls. There were 165 moderate and high risk fire incidents and 1493 low risk fire incidents. Although the number of fire incidents only accounted for approximately 9% of total calls, with moderate and high risk incidents accounting for less than 1%, these calls present a significantly higher risk to the persons, properties and the community as a whole. The remaining 3608 calls varied from hazmat, technical rescue, airport rescue & firefighting, and service calls. Jurisdiction The Pueblo Fire Department responds to all calls for assistance within the City of Pueblo. The City of Pueblo currently covers 53.64 square miles. The department’s response area covers approximately 58.08 square miles. The department has divided the city into three categories: Urban, Rural, and Wilderness areas. These categories are based on population density and accessibility. Nine stations located in the city limits that are considered urban areas and one station located at the Pueblo Airport which is considered a rural area. There are wilderness/undeveloped areas throughout the city limits. Many of these areas are only accessible by foot or all-terrain vehicles. Patients have been transported out of these locations by Flight for Life helicopters in the past when access was difficult. 5 The department is responsible for the Pueblo Municipal Airport, which is located approximately five miles east of the city limits. The airport has the capability of landing most commercial aircraft and is an alternate landing area for Denver International Airport and Colorado Springs Airport. It also is the home to Doss Aviation which is the initial flight training center for future pilots in the United States Air Force. Doss provides this training for several hundred officers annually. The Pueblo Industrial Park is located adjacent to the Pueblo Municipal Airport. The industrial park has several manufacturing and distribution facilities located on the property. These facilities include a 1.5 million square foot distribution center for Target, a large chemical company that deals with large quantities of chemicals, and several other large industrial facilities. Some of the chemical companies have chemists and/or rapid response teams to assist the department in mitigating the incidents. The two major roadways that go through the City of Pueblo are Interstate-25 and US Hwy 50. Interstate-25 is a major north/south transportation route through the center of the United States. It is also a transportation route for nuclear and other radioactive waste from the Department of Energy that is heading to New Mexico for permanent storage. Highway 50 is also a major transportation route from Virginia to California. The Arkansas River and the Fountain creek also run through the city. The Arkansas River has flow rates that vary from a couple of hundred feet per second to several thousand feet per second and has a whitewater park within the city limit. The Fountain Creek also varies in flow greatly depending on weather from the north and is often the source of pollution from sewage spills from cities to the north. Responsibilities The Pueblo Fire Department is responsible for providing fire suppression, emergency medical response, hazardous materials response, technical rescues, water rescues, wildland firefighting, and various calls for assistance within the city limits of Pueblo. The total real property assessed value was assessed at $6.863 Billion in 2012 according to the Pueblo County‘s Assessor’s office. This includes: $4,247,783,000 residential, $1,157,070,000 commercial/industrial, $956,047,000 state assessed taxable properties, and $502,867,000 exempt properties such as schools and churches. The department also conducts over 3600 fire prevention inspections annually on the commercial and industrial structures within its jurisdiction. Topography The City of Pueblo is relatively flat, and is split in half by the Arkansas River. The city is situated at 4692 ft. above sea level. There are seven different bridges over the Arkansas River in the city limits. The southern boundary of the Arkansas River has a bluff that ranges from about 50 to 80ft tall. The Fountain Creek enters the City from the north and runs parallel to Interstate 25 until its 6 confluence with the Arkansas River. The city also has a large amount of open space/wildland areas that range from flat areas, to arroyos, to steep bluffs. Demographics The City of Pueblo had an estimated population in 2012 of 107,577 according to the U.S. Census Bureau. The population is made up of 48.8% males and 51.2% Females. The median age is 36.5 years old. This is slightly higher than the Colorado and National average of 34.3 years old. Pueblo County has a higher than average elderly population. Approximately 15.7% of the population was 65 years and older. The state average was 9.7% and the national average was 12.4%. The city is also approximately 50% Hispanic and 45.2% White/Non-Hispanic, 2.1% Black, and 2.9% other. A language other than English is spoken in 18.3% of the homes. Approximately 22.8% of the city’s population was living below the poverty level in Pueblo in 2009. In 2009, The National Poverty Center reported that 14.3% of all individuals in the United States were living below the poverty level. The median household income for residents of Pueblo was $30,270 in 2009 compared to a state median income of $55,430. Daily Population There has been rapid growth in several communities within 10 miles of the city limits. The total population in Pueblo County is 159,063. Pueblo West currently has 29,637 residents and is located about 7 miles west of Pueblo. The majority of the people work and shop in the City of Pueblo. This affects the daily population of the city and increases the volume of calls for assistance significantly. There are also several large events held within the city limits throughout the year. The Colorado State Fair is an eleven-day expo that was attended by 517,140 in 2010. The National High School Rodeo is also held annually at the Colorado State Fair grounds. Deployment Capabilities The Pueblo Fire Department currently has eight ALS engines and two ALS 61ft combination engines. All engines are staffed by a minimum of three personnel. There is a 105 ft. aerial truck that is staffed by a minimum of three personnel, a rescue/squad staffed by a minimum of two personnel and two airport crash rescue trucks cross-staffed by Engine 10’s crew. There is a hazardous materials truck with decontamination trailer, two brush trucks, and a brush tender truck that are cross-staffed as needed. The department’s reserve fleet consists of four reserve engines, one reserve aerial, two reserve squad trucks and several staff vehicles. All crewmembers at Station 1 are hazardous materials technician level trained and cross-staff the hazardous materials unit. Additionally several members of the department have been trained to the level of hazmat highway and/or tank car specialists. 7 Map of City by Fire Management Zones/Still Districts 8 Growth Trends Even with a relatively consistent population, the City has been building northward and southward. This growth appears to be to accommodate the population increases within the county. Pueblo has added a couple of large industrial and manufacturing companies over the past few years. Vestas is a company that makes large windmills for power generation and is now located in the southern industrial park. Comanche power plant has added a new generator that more than doubled their capacity. The majority of the power generated by Comanche goes onto the national grid which means that if there is a major incident at this facility the impact will reach beyond the City of Pueblo. Black Hills Energy has recently completed a natural gas fired power generation facility just north of the airport industrial park. This facility currently provides the majority of the power for the City of Pueblo. Current Automatic Reciprocal Aid Agreements The Pueblo Fire Department has several reciprocal aid agreements with surrounding communities. The agreements are broken into two categories: standard mutual aid and hazardous materials responses. The Standard Reciprocal Aid Agreements: I. II. III. IV. V. VI. Transportation Test Center, AAR Pueblo Rural Fire Protection District Pueblo West Metropolitan District United States of America / Pueblo Army Depot Rocky Mountain Steel / EVRAZ West Metro Fire Protection District The Pueblo County Reciprocal Hazardous Materials Incident Assistance Agreement: I.

These factors must be identified and prepared for by the department. All Fire Management Zones (FMZ) have a diverse mix of occupancy types with the exception of Station 10. All of the areas have residential occupancies mixed in with light commercial. Some of the areas, such as the Union Ave business district and the Northern Avenue business district, have commercial structures that were built at the turn of the century prior to modern building and fire codes. Many of these structures have residential apartments above them that have had several renovations done to them often creating large hidden voids that are unknown even to the current owners. Most of these structures also share common walls and have common basements and attics that are shared. Pueblo also has the Comanche Power Generation Plant located in its boundaries. This power generation facility supplies power to a large portion of the western US power grid. Comanche has also recently completed an addition that more than doubled its capacity to 1,410 Mega Watts. Due to annexation in 2009, the department is solely responsible for the fire protection and technical rescue at this facility. The primary fire risk at this facility is a coal fire in the coal supply/conveyor areas. The coal is the volatile Powder River Basin Coal out of Gillette, WY. The plant currently burns approximately 1,520,000 lbs. /hr. when all three generators are working at full capacity. Another factor that is unique to Pueblo is the location of the Colorado State Mental Health Institute. The facility is located on 300 acres in the heart of Pueblo and houses approximately 478 patients with all levels of psychiatric problems. This includes a stand-alone forensic ward for the criminally insane. The campus also is home to three of the Colorado Department of Corrections facilities. The Facilities, La Vista Correctional Facility (women), San Carlos Correctional Facility (special needs), and the Youth Offender System (Underage offenders), house a total of 1,075 inmates. San Carlos Correctional Facility has been approved for a 250-bed expansion that will double the current capacity. This entire Colorado State Mental Health Institute campus requires special treatment with the movement and/or evacuation of the residents. The institute also has a labyrinth of tunnels that connect the various buildings. Additionally, all of these facilities are located within a half mile of a large rail yard. In the event of train derailment or spill of hazardous materials from a train, the residents of these facilities cannot self-evacuate due to their custody levels. This would significantly increase the risk to these people and the responders trying to evacuate them. 10 Pueblo Dam is located six miles west of the City of Pueblo. The dam was built from 1970 to 1975 and was modified from 1998 to 2000. The total storage is 357,000-acre ft. at an elevation of 4,898.7ft. This structure poses a major risk to the city in the event of a failure of the dam. Studies have shown that a catastrophic failure would result in several thousands of lives lost and major infrastructure damage/loss. These projections are shown on the City of Pueblo Flood Plain map in the administration. Natural Gas Pipelines Colorado Interstate Gas has high-pressure transmission lines that come into the City of Pueblo from the north and south ends. The north end of the system, near Eva Baca Elementary School has parallel 8-inch mains. The south end of the system at the EVRAZ steel mill meter station has a single 16-inch main. The exact location of the pipes throughout the city, the system pressures and total capacities are protected due to security concerns. Colorado Interstate Gas can be contacted for specific details. Terrorism and Weapons of Mass Destruction Terrorism and weapons of mass destruction have become a larger risk since the attacks of September 11, 2001. Pueblo is located in close proximity to Fort Carson Military Base, Peterson Air Force Base and North American Aerospace Defense Command (NORAD). All are located in Colorado Springs, 45 miles to the north. The Pueblo Army Chemical Depot is located just east of the city of Pueblo and is the location of a large amount of military munitions. Currently there are approximately 780,078 shells with about 2,611 tons of mustard gas, a blister agent that is set for destruction per an international treaty. The Department of Transportation Test Track is also located within Pueblo County. All of these factors make terrorism a realistic risk for Pueblo and Pueblo County. These potential risks are addressed in the Pueblo County Emergency Operations Plan-Annex E – Terrorism. 11 Chapter 3 Risk Assessment Methodology The accreditation team obtained the data for this document from several sources. The response data was all obtained from High Plains FireManager records management system (RMS), the department’s current RMS. The statistical data was obtained from the following sources: the U.S. Census Bureau, CityData Pueblo, the Centers for Disease Control (CDC), Colorado State Patrol, Burlington Northern Santa Fe (BNSF) Railroad, Colorado Department of Public Health, National Wildfire Coordinating Group, National Weather Service, and the State of Colorado Division of Emergency Management. All of the response data that was extracted from the RMS was exported into an MS Excel spreadsheet. The data was then sorted and analyzed by risk type and risk level. Tables, charts, and graphs were then built based on the results of the analysis. The draft document was then presented to the command staff for review and any additions the chiefs determined were necessary to properly express the risks within the city. The document was then sent to a member of the accreditation community from outside the department for further review. A final review was conducted and any necessary changes were made. 12 Chapter 4 Fire Risk The department has experienced several large and historically significant fires over the last 100 years. Some of them were: Holmes Hardware Company Fire on February 22, 1915. Holmes Hardware was one of the largest hardware stores in the state. Grand Opera House Fire on March 1, 1922. The entire department responded to this fire. The outside temperature was 22 degrees below zero and the call came in at 1:15am. Central Block Fire on August 29, 1953. The entire department responded. One fatality was attributed to this fire. Total fire loss was $998,000.00, the most expensive in Pueblo history up to that point. Pueblo Ice & Cold Storage Fire on October 24, 2007. Thirty firefighters responded with 8 engine companies and two aerials. This was a 20,000 sq. ft. facility that was fully involved when the alarm came in at 12:07am. The Branch Inn Explosion & Fire on November 13, 2008. This explosion occurred as the result of a natural gas leak under the structure over a period of time. The results were the complete destruction of the bar and two adjoining buildings. One person was killed and several were injured. (The ATF sent a national response team along with members of Ft. Carson Fire’s Rescue Specialists, the FBI, FEMA’s Urban Search and Rescue team - Colorado Task Force One and many other local responders.) The City of Pueblo has a very diverse blend of structures that pose a fire risk. There are a large number of homes that were built in the early 1900’s that have been converted into multifamily apartments, several large modern homes with light weight construction, mixed occupancies that contain small commercial stores on the first floor and residential apartment on the upper floors, several multistory senior living facilities, various mixed industrial facilities, large commercial businesses, and two large power plants with a possible third in the near future. In order to address these risks as thoroughly as possible they will be broken into three separate categories: Low risk fires, moderate risk fires (residential) and high risk fires (commercial/industrial). There are residential occupancies located in every Fire Management Zone (FMZ) except in the industrial complex located around the Pueblo Municipal Airport. This is a rural area that is protected by Fire Station 10. The remainder of the city has a mix of residential, commercial, assembly, industrial, educational, institutional (healthcare, detention & corrections), storage, and special properties. 13 Fire/Still – Low Risk (Single Company Response) The department classifies any single company fire response as a fire/still – low risk. These include: car fires, trash fires, grass fires, and any other small fire incidents. Structure Fire – Moderate Risk (Structures with a risk score of below 46) The city has 33,866 single family dwellings and about 3,500 commercial occupancies that are classified as having a risk score below 46. The occupancies range from over 100 years old to brand new structures. The fire loss in Structure Fire – Moderate Risk for 2012 was $2,173,586.00 or $20.20 per capita. This is lower than the regional (west) average of $24.80 and the national average of $30.00 per capita for a city of comparable size according to the 2010 National Fire Protection Agency fire loss statistics. The total pre-incident value of these structures was $11,056,934.00. This equates to a real total property conservation value of $8,883,348.00 for 2012. Structure Fire – High Risk (Structures with a risk score of 46 or higher) The department strives to inspect every commercial and industrial occupancy on a regular basis. Currently all high and moderate risk occupancies; multi-family housing, schools, hospitals, nursing homes, and any state mandated inspections are conducted annually. The department plans to increase the frequency of high risk occupancies with a fire flow of greater than 5,000gpm to twice a year. The low risk occupancies are inspected every other year with half of them being conducted each year. There are 3,792 assigned, inspectable multi-family dwellings, multistory senior living facilities and commercial/industrial occupancies located in the City of Pueblo’s jurisdiction as of 2012. The seven multistory senior living facilities are sprinkled, Type 1 construction buildings. They are not facilities for residents that require medical/nursing around the clock care. They are operated by the City of Pueblo Housing Authority. The fire loss for structure fire – high risk for 2012 was $218,000.00. The total pre-incident value of these structures was $16,300,000.00. This equates to a real total property conservation value of $16,082,000.00. 32 29 27 1 9 4 23 2012 Occupancy Profile for City of Pueblo 24-hour care Nursing homes, 4 or more persons Adult education center, college classroom Aircraft hangar Airport passenger terminal Alcohol or substance abuse recovery center Amusement center: indoor/outdoor Assembly, other (Non-Specific) 14 24 15 1 5 38 63 3 5 1 2 525 124 7 59 7 22 8 1 3 42 4 1 12 16 1 86 13 1 38 31 1 2 1 32 2 12 10 3 141 4 3 49 Asylum, mental institution Athletic or health club Auditorium, concert hall Ballroom, gymnasium Bank Bar or nightclub Billiard center, pool hall Boarding/rooming house, residential hotels Bowling establishment Bus station Business office Church, mosque, synagogue, temple, chapel Clinic, clinic-type infirmary Clinics, doctors’ offices, hemodialysis center, other Clubhouse Clubs, (Private Clubs, Meeting Halls), other Communications center Computer center Construction site Convenience store Convention center, exhibition hall Courthouse Day care, in commercial property Department or discount store Detached residential garage Doctor, dentist or oral surgeon office Dormitory-type residence, other Dump, sanitary landfill Eating, drinking places, other Educational, other (Non-Specific) Electrical distribution Electricity generating plant Electronic amusement center Elementary school, including kindergarten Energy production plant, other Fire station Fixed-use recreation places, other Flammable liquid distribution, flammable liquid pipeline Food and beverage sales, grocery store Funeral parlor (with or without chapel) Gas distribution, gas pipeline General retail, other 15 23 16 1 6 32 67 1 1 8 16 4 17 3 3 3 78 10 372 209 1 168 13 9 9 1 2 1 2 3 1 153 17 2 6 6 104 24 2 4 29 13 Health care, detention, & correction, other (Non-Specific) High school/junior high school/middle school Hospices Hospital - medical or psychiatric Hotel/motel, commercial Household goods, sales, repairs Ice rink: indoor, outdoor Industrial plant yard – area Industrial, utility, defense, ag., mining, other (NonSpecific) Jail, prison (not juvenile) Laboratory or science laboratory Laundry, dry cleaning Library Live performance theater Livestock production Manufacturing, processing Mental retardation/development disability facility Mercantile, business, other (Non-Specific) Motor vehicle or boat sales, services, repair Movie theater Multi-family residence (more than 2 families) Museum None Office: veterinary or research Oil or gas field Outbuilding or shed Outbuilding, protective shelter Outside or special property, other (Non-Specific) Parking garage, general vehicle Passenger terminal, other Personal service, including barber & beauty shops Places of worship, funeral parlors, other Police station Post office or mailing firms Preschool Professional supplies, services Public or government, other Radio, television studio Railroad yard Recreational, hobby, toy, pet, garden, sporting goods Reformatory, juvenile detention center 16 3 19 14 17 171 1 2 20 216 6 67 3 49 85 1 9 13 10 11 38 6 36 3792 Refrigerated storage Residential board and care Residential or self-storage units Residential, other (Non-Specific) Restaurant or cafeteria Roller rink: indoor or outdoor Schools, non-adult, other Service station, gas station Specialty shop Stadium, arena Storage, other (Non-Specific) Swimming facility: indoor or outdoor Textile, wearing apparel sales Unable to classify Undetermined (Not for Life Safety) Utility or Distribution system, other Vacant lot Variable-use amusement, recreation places, other Vehicle storage, other Warehouse Water utility (blank) The engine companies conduct the majority of the annual inspections that are located in their FMZ. In 2012, 100% of the occupancy inspections assigned were inspected. In 2012 every inspected structure had a completed hazard assessment, the department is in the process of performing quality assurance reviews on the occupancy scores to ensure correctness. As the inspections are entered into the Report Management System (RMS), a hazard assessment is calculated. This hazard assessment considers the following factors when calculating a risk score: 1) Water Supply 2) Predominant Construction Type 3) NFPA Property Use 4) Number of Above Grade Floors 5) Height in Feet (from lowest point of vehicle access) 6) Presence of Below Grade Floors 7) Total Square Footage 8) Maximum Building Population (Occupancy Load if Assembly) 9) Automatic Sprinkler Systems 10)Fire Alarms Systems 17 11)Hazard of Contents 12)Hazardous Materials 13)Mobility of Occupants 14)Fire Department Access 15)Electrical Hazards After these factors are totaled the risk score is assigned. The department defined the following risk levels based on the hazard scores: a score of 1-30 indicates a low fire risk; a score of 31-45 indicates a moderate fire risk; and a score of 46 & up indicates a high fire risk. For the 2012 inspection cycle the following was identified: 1,484 occupancies had a low fire risk score given to them, 2,238 occupancies with a moderate fire risk, 70 occupancies with a high fire risk score. Below is a list of the high fire risks.

This was done for a couple of reasons: 1. There are significant threats that could involve a large population. 2. There are a significant amount of non-ambulatory persons 3. There are a significant hazards to responders 4. Loss of the facility would greatly impact the population of Pueblo. The following are explanations of these risks: Black Hills Natural Gas Power Generation Facility (risk value - 47) This facility is located between the east side of the city and the industrial park at the airport. It is a new stateof-the-art natural gas power generation facility. This facility uses high quantities of unodorized natural gas. Black Hills Energy Generating Plant (risk value – 46) – This is a power generation facility that presents three major hazards. The high voltage electricity, a large diameter natural gas feed to the facility and as much as 300,000 gallons of diesel stored in a container next to the structure. St Mary Corwin Hospital (risk value – 53) – This structure is one of two hospital located in the City of Pueblo. While this facility is fully sprinkled, it houses a large number of patients and medical personnel. Many of the patients are in such poor health that they would require special assistance evacuating in a fire. The hospital also has a large cancer center & radiology department with nuclear medicine capabilities. KMG Electronic Chemicals (risk value – 54) – 250 William White Blvd –This facility refines, distills and distributes various chemicals and acids. The most serious acid that they handle is hydrofluoric acid, one of the strongest and most corrosive acids known. Parkview Hospital (risk value – 55) – This structure is one of two hospital located in the City of Pueblo. While this facility is fully sprinkled, it houses a large number of patients and medical personnel. Many of the patients are in such poor health that they would require 20 special assistance evacuating in a fire. The hospital also has a large radiology department with nuclear medicine capabilities. Comanche Power Generation Facility (risk value – 70) – This facility is a major coal fired electrical generation plant that, when fully operational, produces 1470 Mega Watts of electricity. A large amount of this electricity provides power to the western power grid. This facility has smoke stacks that exceed 500 ft. tall with workers working at the 385ft level daily. It also has over 100 permit required confined spaces. BKEP Materials, LLC (risk value – 63) – This facility produces asphalt. They have a capacity of over 3,831,000 gallons of various chemicals that can be stored on site. These chemicals include: Asphalt, Caustic Soda, Fuel Oil #2, and Sulfur (Molten). Additionally, this facility is located next to Black Hills Energy Generating Plant and Acorn Petroleum. Both of these facilities have over 100,000 gallons of fuel on site. If this facility were to be involved in a large fire it is possible that all three of these facilities would become involved simultaneously. These facilities are located in the center of the Union Ave Historic Business District. Fire Flow Calculations for the Highest Fire Risk in each FMZ The Pueblo Fire Department used the International Fire Code (IFC) 2009 Edition for calculating fire flow needed at high risk structures and determining offensive vs. defensive attack. Bear in mind that this is for a worst case scenario and that the on scene incident commander would make the final decision on the strategy employed on any incident. Station 1 – Parkview Medical Center – 500,000 sq. ft. – Type I/Type III – Sprinkled – 2000gpm needed for an offensive fire. This structure is an extensive hospital complex that covers two city blocks. While the building is sprinkled, there is a large section of the original building that is type III construction. Hazard score of 59. Station 2 – Advanced Auto Parts – This is a 15,000 sq. ft. auto parts store – Type V – Nonsprinkled – 3,250gpm needed for an offensive fire. This building has good access. There is also a significant amount of hazmat at this facility such as sulfuric acid in batteries and auto fluids. Hazard score of 50. Station 3 – Broadway Arcade – 63,000 sq. ft. – Type III – Non-sprinkled – 5250gpm needed for an offensive fire. Because the large life safety risk (29 apartments in this building on the second floor) and several access problems due to the buildings proximity to power lines and adjacent buildings, this would require the largest response to a working structure fire of any building in the city. This building has been preplanned more often than any other building in the city and will most likely continue to be. Hazard score of 49. 21 Station 4 – St Mary Corwin Hospital – 812,701 sq. ft. – Type II – Sprinkled – This is a large hospital complex on the south side of the city. This structure is considered high risk due to the large patient population and the access issues. Hazard score of 53. Station 5 – American Battery – 2,500 sq. ft. – Type III – Non-sprinkled – 1500gpm needed for an offensive fire. Hazard Score of 46. Station 6 – Comanche Power Plant – 1,000,000 + sq. ft. – Type II – Non-sprinkled – coal-fired power generation facility. This facility uses a very volatile “Powder River Basin Coal” in the furnaces. This coal spontaneously combusts when not used for an extended period of time. The facility also has over 100 confined spaces and structures exceeding 450 feet in height. Hazard score of 70. Station 7 – Big Daddy’s Bowl – 35,148 sq. ft. – Type III – Non-sprinkled – 4000gpm needed for an offensive fire. This building is a large bowling alley with a bowstring trussed roof. Any offensive actions at this structure would be limited due to the roof construction. Hazard score of 39. Station 8 – Woodhaven Condos – 24,000 sq. ft. – Type V – Non-sprinkled – 4250gpm needed for an offensive fire. There is a large life safety risk and access. Hazard score of 48. Station 9 – La Dolce Vita Apartment Complex – Two structures that are each 18,778 sq. ft. – Type V – Non-sprinkled – 3,750gpm for an offensive fire in any of these apartments. There is also very limited access to these structures and will require a long hand lay across a vacant field. Hazard score of 50. Station 10 – BF Goodrich – 34,500 sq. ft. – Type II – Non-sprinkled – 4000gpm needed for an offensive fire. This facility manufactures carbon fiber aircraft brakes. The process involves the use of large industrial ovens. Hazard score of 62. 22 Structure Fire Risk Summary In summary, the main fire risk in Pueblo continues to be a moderate risk (residential) fire. These are the most common type of structure fire and tend nationally to injure or kill the most people. In 2012 the department responded to structures fires spread out over different times of day and days of week, however there appeared to be an increase in call volume between 5pm and 8pm daily. Low Risk Fires in Outbuildings/Sheds Detached Residential Garages Dumpster/Trash Fires Car/Vehicle Fires High Risk 1 and 2 Family Residential Structure Fire Low Frequency High Frequency Moderate Risk 23 Commercial Fires Multi-family Residential Structure Fires Industrial Fires Fire Involving Hazmat Explosions Chapter 5 EMS Risk The Pueblo Fire Department responds to over 11,000 emergency medical service (EMS) calls annually. These calls range from very minor injuries or illnesses to critical/life threatening medical incidents. These incidents account for more than 69 percent of the calls for service by the department. In order to respond to these calls appropriately it is important that the department determine what factors affect the EMS call types and frequency. Below are some of these factors. Elderly As stated in Chapter 1, 14.4% of the population is 65yrs old or older. The state average was 9.7% and the national average was 12.4%. Diabetics (Overweight-Hispanic) In 2007, the CDC showed that diabetes affected Hispanic Americans at a 5% higher rate at 26.1% compared to Non-Hispanic White Americans at 21.1%. Adult Diabetes Rates: Adult Obesity Rates: Pueblo: 7.0% Colorado: 5.3% Nationally: 7.8% Pueblo: 23.3% Colorado: 18.6% Nationally: 26.6% Mental Health (State Hospital & Spanish Peaks Mental Health) All mental health patients discharged from the State Hospital are discharged into Pueblo County regardless of where they originally came from. Inpatient Population: 450 Colorado State Hospital – Approximately Outpatient Population: 3,809 in Pueblo County Indigent & Homeless Population Pueblo County has a homeless population of 2,800 or 2.6% of the county. Additionally, approximately 22.8% of the population is living at or below the poverty level according to CityData – 2009. 24 Uninsured and/or indigent According to the Colorado Fiscal Policy Institute in 2008, 26% of the adult population (age 18 – 64) were without health insurance. This is considerably higher than the state (17%) and national (14%) average. The indigent population is approximately 11.4% according to research conducted by American Medical Response (Currently the sole provider of ambulance service in Pueblo). While this is just one source, we believe that it gives a glance at the indigent population that we are affected by in our daily service to the City of Pueblo. Due to the high population of people with mental health problems, a large homeless population, and a large number of people without health insurance, the department tends to be the primary healthcare provider for these people. These people also tend to allow minor health issues become more significant before seeking care. Below is a chart that lists the EMS calls by type that the department responded to in 2012. 2012 EMS Calls by Nature of Problem Nature Unclassified medical problem Fall Automobile related accidents Unconscious Breathing difficulty Heart problem/ chest pain Seizure Assault with injury Abdominal pain Diabetic problem Overdose Cardiac arrest Back pain Head injury Stroke Attempted suicide Bleeding Drunk party Emotional problems Broken Bone Dizzy Laceration Allergies Stabbing Choking 25 Total 3167 1025 953 945 825 760 691 431 339 334 277 269 192 159 142 127 123 121 117 115 108 105 57 57 42 CO alarm with illness Assist party Bite wound Shooting Fever Miscarriage Taser removal Child birth Hanging Pepper spray per PD request Burn Eye injury Drowning Electrocution 26 38 37 33 27 23 22 22 19 17 15 6 4 3 1 EMS Risk Summary Based on the above information, EMS continues to be the largest demand for service for the Pueblo Fire Department. The department responded to 11,769 EMS calls for service in 2012 or 32.2 calls per day. This is a high probability/low consequence event. Falls, unconscious, diabetes and cardiovascular calls tend to be some of our most common calls. We believe that this is due to the higher than average elderly, indigent, and overweight population. Pueblo also has a large Hispanic population, which data shows have a 5% higher risk of diabetes. Low Frequency Less Than 50/Year High Frequency 51+/year Pueblo also responds to a large volume of calls that are the result of drug and/or alcohol abuse. These calls are listed above as ETOH/Drug Overdose/Poisoning. This number is believed to be much higher since the majority of the assault calls are the result of drug/alcohol abuse. Low Patient Risk Moderate Patient Risk General Weakness Neck/Back Pain Abrasions & Lacerations ETOH Pain Behavioral Problem Syncope/Dizziness Headache/Pain Strain/sprain/dislocations Respiratory Problem Seizures Abdominal Pain Diabetic Problem Nausea/Vomiting/Diarrhea Fracture Infection Cardiac Dysrhythmia Drug Overdose/Poisoning Chest Pain Unconscious/Altered LOC Head Injury Multiple Trauma Cardiac Arrest Stroke (CVA/TIA) Choking/Airway Obstruction Nose Bleed (Epistaxis) Ingestion Dehydration Blood Pressure Bite/Sting Palpitations Eye Injury GYN Problems OB Patients Allergic Reaction Penetrating Trauma GI Bleed Burns Hyperthermia Hypothermia Drowning/Near-Drowning Shock 27 High Patient Risk Chapter 6 Hazmat Risk The City of Pueblo and the department face several Hazmat risks from three main sources: Highway, Rail, and fixed facilities. Highway Risk As stated earlier the city has two major highways that bisect the city: US Highway 50 and Interstate 25. Both of these highways are used for the shipment of hazardous materials. The Colorado State Patrol conducts regular flow studies to monitor the amount of hazmat traveling through the region by road. Rail Risk The city has a large rail yard that also runs through the center of the city. The two main rail companies that transit through Pueblo are Union Pacific Railroad and Burlington Northern & Santa Fe Railway. They transport a wide variety of chemicals from hazard classes 2-9. In 2009, the BNSF Railway transported a wide range of chemicals through Pueblo by rail. Below is a list of the chemicals and the number of loaded cars that carried them: Liquefied Petroleum Gas - 4969 Cars Alcohols – N.O.S. – 4831 Cars Various Fuels – 11,687 Cars Various Acids – 3684 Cars Phenol–Molten - Poisons – 5 Cars Molten Sulfur & Other Heated Substances – 19,017 Cars Sodium Hydroxide – 808 Cars Various Other Flammable Liquids – 4198 Cars Anhydrous Ammonia – 1482 Cars Ammonium Nitrate – 392 Cars Radioactive Materials – Excepted Package – 3 Cars Other Chemical Cars – 1105 Cars 28 In addition to the above list Union Pacific transports similar commodities annually. Excel Energy also owns and operates 4 trains that continuously travel between Gillette, Wyoming and the Comanche Power Plant in Pueblo delivering as many as 125 cars of Powder River Basin Coal to the plant daily. 29 Fixed Facilities The following hazardous materials fixed facilities chemical quantities were reported to the Colorado Department of Public Health and Environment on 02/22/2010.

Pueblo’s roadways and railways are major transportation routes for a large variety of chemicals ranging from fuel to hydrofluoric acid to radioactive waste. Most of these transport vehicles are designed to withstand collisions and therefore reduce the risk of a large scale event in our jurisdiction. However, due to the potential and proximity to large populations of residents, the department is equipped and trained to respond to and mitigate these types of incidents also. Low Risk High Frequency Small Fuel/Oil Spill (less than 5 gallons) Antifreeze Leak (less than 5 gallons) CO Alarms Moderate Risk Low Frequency High Risk Natural Gas Leak (Outside) Residential Natural Gas Leak (Inside) Hazmat Fixed Facilities Incident Large Fuel/Oil Spills Chemical Spills/Leaks Meth Labs Radioactive WIPP Shipments 32 Commercial Natural Gas Leak (Inside) Hazmat Rail Incident Hazmat Fires Hazmat Highway Incident Chapter 7 Technical Rescue Risk Water Rescue Risk Street Flooding A significant threat to the City of Pueblo is the Pueblo Dam on the Arkansas River located just west of the city limits. The total storage is 357,000-acre ft. at an elevation of 4,898.7ft. A vulnerability assessment for the Pueblo Dam was published on September 22, 1999. The assessment stated that a breach in the dam would result in the property damage to thousands of homes and businesses in excess of several hundred million dollars. It would also result in a great loss of life. In the event of a catastrophic dam failure, the water levels are projected to reach the 500-year flood level. This document is protected due to Homeland security and specific values are not available to the public. A copy of the document is kept in a secure location within the Emergency Operations Center. Swift Water Rescue There are three moving bodies of water through the city: the Arkansas River, Fountain Creek, and the Bessemer Ditch that pose a swift water risk to our residents. The largest potential exists in the Arkansas River which runs through the center of the City. The Arkansas River exits the Pueblo Reservoir approximately six miles west of town and flows west to east through the City and divides the City in two. The Fountain Creek merges with the Arkansas River at the southeast corner of the City. The river is actively used for recreation. A nature trail runs from the reservoir following the river through the entire city. Bicyclist, runners, and walkers actively use the trail. The river also has two low head dams and a popular white water kayak course. These features have trapped victims in the past and caused several people to venture beyond their skill level leading to several rescues and a few recoveries. Historically Pueblo has had several large floods that affected the city and its residents. The 1921 flood of the Arkansas River caused $19,000,000 in property damage and caused the known deaths of 120 people. There were also 142 people that were unaccounted for. The Fountain Creek flows south from Colorado Springs into Pueblo and flows north to south. The Fountain is normally a shallow flowing waterway, but during heavy upstream storms the Creek can become a very dangerous, swift moving body of water that causes significant damage to the areas around it. The 1965 flood on the Fountain Creek did not result in any deaths; however it caused $3,706,000 in property damage. And in the spring of 1999, a large storm moving through the southern part of the state caused major flooding in the Fountain Creek. This flooding began to 33 erode streets and land around the Pueblo Mall and the local Target department store. The flooding was stopped at the foundation wall of the Target store by an emergency response of excavators and heavy equipment operators. The President declared Pueblo County a flood disaster as a result of this storm. Parts of Pueblo’s downtown business district lie directly within the historic floodplain of the Fountain. The mean annual flow of Fountain Creek is greater than 196 cubic feet per second. This will increase greatly in the coming years, to as much as 573 cubic feet per second, as the City of Colorado Springs to the north begins exchanging water that will be taken from the Pueblo Reservoir and returned to the Arkansas River via the Fountain Creek. The Bessemer Ditch is a canal that runs through the west part of the City and supplies water to local farmers. This canal tends to be a low, slow moving body of water throughout the winter months but rises significantly from spring through fall. It runs along several residential streets and is normally protected only by a chain-link fence. The majority of incidents in the Bessemer Ditch have been vehicles that have driven into it. Due to the slow current and relatively shallow water, 3-6 feet, these accidents usually result in little if any injury to the victims and only minor environmental issues. Lakes and Ponds There are nine lakes or ponds of various sizes within the City of Pueblo and a manmade river walk downtown. Two of these ponds, which are located in City Park, along with Lake Minnequa are in close proximity to residential areas. Additionally, Lake Minnequa is the focal point of a new recreation area that will serve the south end of the city. All of the lakes and ponds present possible ice rescue and drowning scenarios due to their popularity. Confined Space Risk There are several areas that pose confined space risk throughout the City of Pueblo. The largest of these is Comanche Power Generation Plant. This facility currently has over 100 confined spaces that require permits for entry. Some of these spaces have small entry points that immediately drop in excess of 70 ft. to the floor below. The facility also has places where the entry point is 16 inches in diameter. Due to the fact that this is a power generation facility many of the confined spaces have high voltage lines that also run through the confined spaces. There is currently one other older power plant located downtown and a new natural gas power plant under construction northwest of the Pueblo Airport that will have similar confined spaces. Trench Rescue Risk There is regular trench work performed throughout the city by the city streets department and by road, highway, and utility contractors. These trenches vary in depth and length. Many of these companies have a first response team but the primary trench rescue responsibilities fall to the department. 34 The City of Colorado Springs is currently constructing a 60 inch water supply line from the Pueblo Reservoir into the Colorado Springs, approximately 40 miles to the north. This pipe will transport approximately 40 million gallons of water daily. The pipeline construction involves trenches with depths in excess of 10 feet and is projected to be completed in 2014. Extrication Risk Auto Extrication Motor vehicle accidents with entrapment have historically been the most common technical rescue for the department. These accidents commonly involve two or more passenger vehicles and tend to occur along Pueblo Blvd, Hwy 50, and Interstate 25. The department has an engine company on the north and south end of the city with hydraulic extrication tools (Hurst) on the units. There is also a set on both the heavy rescue and the truck company which both respond out of Station 1. Heavy Equipment Extrication Heavy equipment extrication rescues are rare occurrences. The city has annexed in two large power generation facilities in the last few years which may increase the number of these types of calls. There are also several large industrial plants in the region that have requested assistance for injuries from heavy equipment. Elevator Rescue Risk The main elevator rescue calls the department responds to are for people stuck in elevators between floors. These are typically handled by the first due units. These incidents happen on a regular basis and typically have not resulted in any injuries. Weather has a significant effect on the number and frequency of these incidents due to power outages. High Angle / Low Angle Risk The main high angle risks that are faced by the department are located at the local power plants and in the light towers located in the BNSF rail yard. The superstructure of the Comanche Power Plant exceeds 350ft in many places and the towers vary in height from 485ft to over 500ft. Environmental engineers work at the 385ft level of the stacks regularly while taking environmental readings. The elevators that travel to the top of these stacks have failed in the past requiring the workers to climb down the attached ladders. 35 Structural Collapse Rescue Risk The city has a large amount of unreinforced masonry buildings located throughout its boundaries. The majority of these buildings are located in the downtown area, around the Union Ave business district and along the Northern Ave business district. Unreinforced Masonry (URM) is a very brittle material and does not perform well when the structure sustains damage. Walls are constructed with a thickness of three or more bricks laid long way, side by side, five or six layers high (courses), and then a layer is placed with the bricks at 90 degrees, and so on. These building techniques date back as far as the 1700’s in parts of the U.S. The strength of these buildings is highly dependent on the mortar strength. Decorative veneers also pose a significant risk of collapse. These veneers were often laid up with building paper between them and the URM wall, and were anchored with wire or galvanized ties. The ties normally corrode away within 20 years or so, leaving a heavy brick face that is susceptible to collapse when subjected to a lateral load. The Pueblo Fire Department experienced a collapse of an URM front wall in the Union Ave Historic District within the last 10 years. The collapse caused significant damage to vehicles near the building but fortunately did not injure any people. The Pueblo Fire Department also responded to another building collapse as the result of a natural gas explosion on November 13, 2008. The Branch Inn, a local bar, was totally destroyed in the explosion which also destroyed and adjacent building and significantly damaged another. One person was killed in this collapse and two others were trapped in the rubble. The gas explosion is believed to be the result of a faulty splice placed in the natural gas line decades ago. The risk of this occurring again in the future continues to exist due to the fact that similar splices were used for years throughout the city. Chieftain Photo by Bryan Kelsen 36 Technical Rescue Risk Summary The primary technical rescue risk for the department is auto extrication. The department responds to several calls of this nature on an annual basis. These incidents would be classified as a high frequency/moderate risk event. This is primarily because of the limited number of people involved. The department also responds to several swiftwater rescue calls each year. Most of these calls occur in the city’s white water park in the river and at one of the two low head dams. Low Frequency High Frequency Low Risk Elevator Rescue Moderate Risk Auto Extrication Confined Space Rescue High/Low Angle Rescue Trench Rescue 37 High/Special Risk Structural Collapse Swiftwater Rescue Chapter 8 WILDLAND FIRE RISK Wildland Fires The City of Pueblo has a large area of undeveloped land within the city limits. There is approximately 22,560 acres of unimproved land, nearly 63 percent of the city, which would be classified as wildland. These areas range from the large open areas of prairie grasses within Pueblo Motor Sports Park and around the edges of the City to the wide areas of mixed grasses and timber along the banks of the Fountain Creek and Arkansas River. Many of these areas surround residential and commercial properties. In order to better assess the wildland fire risk the following factors need to be examined: Fuel types, topography, fire weather and urban interface concerns. Fuel Types The National Wildfire Coordinating Group (NWCG) break wildland fuels into 13 fuel groups or models. These models are based on vegetation type: Grass (Models 1-3), Shrub (Models 4-7), Timber Litter (Models 8-10), and Logging Slash (Models 11-13). The primary fuel models found within the City of Pueblo are Models 1-6. These models are described below: Fuel Model 1 – (1 foot deep) Fire spread is governed by the fine herbaceous fuels that have cured or are nearly cured. Fires are surface fires that move rapidly through cured grass and associated material. Very little shrub or timber is present, generally less than onethird of the area. Grasslands and savanna are represented along with stubble, grass-tundra, and grass-shrub combinations that meet the above area constraint. Annual and perennial grasses are included in this fuel model. Fuel Model 2 – (1 foot deep) Fire spread is primarily through the fine herbaceous fuels, either curing or dead. These are surface fires where the herbaceous material, besides litter and dead-down stemwood from the open shrub or timber overstory, contribute to the fire intensity. Open shrub lands and pine stands or scrub oak stands that cover 1/3 to 2/3 of the area may generally fit this model but may include clumps of fuels that generate higher intensities and may produce firebrands. Some pinon-juniper may be in this model. Fuel Model 3 – (2.5 feet deep) Fires in this fuel are the most intense of the grass group and display high rates of spread under the influence of wind. The fire may be driven into the upper heights of the grass stand by the wind and cross over standing water. Stands are tall, 38 averaging about 3 feet, but considerable variation may occur. Approximately one-third or more of the stand is considered dead or cured and maintains the fire. Fuel Model 4 – (6 feet deep) Fire intensity and fast spreading fires involve the foliage and live and dead fine woody materials in the crowns of a nearly continuous secondary overstory. Examples are stands of mature shrub, 6 or more feet tall, such as California mixed chaparral, the high pocosins along the east coast, the pine barrens of New Jersey or the closed jack pine stands of the north-central states. Besides flammable foliage, there is dead woody material in the stand that significantly contributes to the fire intensity. There may be also a deep litter layer that confounds suppression efforts. Fuel Model 5 – (2 feet deep) Fire is generally carried in the surface fuels made up of litter cast by the shrubs and the grasses or forbs in the understory. Fires are generally not very intense as surface fuel loads are light, the shrubs are young with little dead material, and the foliage contains little volatile material. Shrubs are generally not tall, but nearly cover the entire area. Young, green stands with little or no deadwood, such as laurel, vine maple, alder, or even chaparral, manzanita, or chemise are examples. As the shrub fuel moisture drops, consider using a Fuel Model 6. Fuel Model 6 – (2.5 feet deep) Fires carry through the shrub layer where the foliage is more flammable than fuel model 5, but require moderate winds (>8mi/h) at midflame height. Fire will drop to the ground at low wind speeds or openings in the stand. Shrubs are older, but not as tall as shrub types of model 4, nor do they contain as much fuel as model 4. A broad range of shrub conditions is covered by this model. Typical examples include intermediate stands of chemise, chaparral, oak brush, low pocosins, Alaskan spruce taiga, and shrub tundra. Cured hardwood slash can be considered. Pinon-juniper shrub lands may fit, but may over predict rate of spread except at high winds (20 mi/h at the 20 ft. level). Fire behavior is significantly different between fuel models. Fire in the Grass Models (1-3) typically produces the following: Rapid burnout, low intensity, rate of spread of 2,300 to 6,600 feet per hour, and flame lengths up to twelve feet. Fires in the shrub models (4-6) typically have rates of spread between 1,188 to 4,950 feet per hour and flame lengths of 4 to 19 feet. Fire Weather Pueblo has historically had extremely hot summers with a low relative humidity (RH). The summer temperatures regularly reach 100 degrees with an RH below 20%. These conditions coupled with the high winds that are common in our area, especially during approaching thunderstorms, create “red flag” conditions. Red flag warnings are issued when fire danger is extreme. These warnings occur throughout the warmer months in Pueblo. 39 Urban Interface The primary urban interface risk within the City of Pueblo is located on the bluffs on the south side of the Arkansas River and along Pueblo Blvd. in the vicinity of Lake Minnequa. These hillsides and bluffs are covered with tall grasses and heavy brush such as oak brush. There are several homes that sit in among this brush and would be severely threatened in the case of a wildfire in these areas. Wildland/Urban Interface Fire Risk Summary The primary wildland fire risk that the department encounters are small grass fires of less than 1 acre. These fires are typically not threatening residential or commercial structures. These fires are usually handled by the primary responding engine. If these fires show any potential to grow, the brush truck is dispatched. Additional units can be requested by the assistant chief on duty or any of the responding company officers. Low Frequency High Frequency Low Risk Grasses – Contained within residential lots Moderate Risk Grasses – Less than 1 acre (Fuel models 1-3) Grasses– Greater than 1 acre (Fuel models 1-3) River Bottom Fires (Fuel models 1-6) High Risk 40 Bluffs along Arkansas River (Fuel Models 1-6) Prairies around El Camino (Fuel models 1-3) Prairies around city limits (Fuel models 1-3) Chapter 9 Aircraft Rescue & Firefighting Risk Introduction The City of Pueblo Fire Department provides aircraft rescue and firefighting (ARFF) services for the Pueblo Memorial Airport located approximately 5 miles east of the city of Pueblo. The Pueblo Memorial Airport is a medium sized general and commercial aviation airport; it is certified as a Class I airport by the Federal Aviation Administration. Under the regulations of this certification the airport is allowed scheduled operations of medium air carrier aircraft. This allows the airport to handle regularly scheduled aircraft to 126 feet in length, with approximately 120 to 175 passengers. Also under this certification the airport is required to maintain ARFF capabilities to an Index B level. The Pueblo Air Traffic Control Tower is among the busiest in Colorado and ranks in the top 100 nationally for operations handled per year. Scheduled air passenger service is provided by Great Lakes Airlines which code shares with United Airlines for service to Denver International Airport. Due to the airport’s close proximity to several correctional facilities the airport is used by the United States Marshall Service’s Convict Air Transport Service several times throughout the year. 41 The largest user of the Pueblo Memorial Airport is DOSS Aviation which operates the U.S. Air Force initial flight screening program. DOSS will begin training the Predator drone pilots which will add significantly to the number of annual sorties. The school currently processes approximately 2,220 candidates annually, with these candidates staying in dormitory type housing on the airport. DOSS Aviation flies, in excess of 45,000, sorties per year at the airport. In addition they have recently added night operations to the school’s curriculum. In addition, the airports favorable location, close to both Denver International and Colorado Springs Municipal airports, makes it an excellent location for flights experiencing delays and ground holds due to weather at the afore mentioned airports. Pueblo Memorial Airport is favorable in deteriorating weather conditions due to it having a 10,500 foot east-west runway, something lacking at other Front Range airports. This runway (designation 8L/26R) can handle most, if not all, planes flown by both civilian and military fleets. From the period January 2010 to January 2011 the Pueblo Memorial Airport handled 84 diverted flights. Most of these diverted flights being the Boeing 737 and Airbus 300 series aircraft. Recently Great Lakes Aviation procured a larger deicer truck for their use in de-icing diverted aircraft; they are actively marketing this to carriers currently serving Denver and Colorado Springs, citing favorable weather when the other airports are delayed for weather. This could possibly lead to an increase in the number of diverted aircraft into the airport. The airport is also a training site for short field nighttime landing operations for the U.S. Air Force and other branches of the military. A large number of military flights train at the Pueblo Airport throughout the year. The Pueblo Memorial Airport has recently undergone several capital improvement projects with more planned well in the near future, all these improvements are aimed at increasing the usage and the safety of the airport. Along with the planned growth of the airport will come more usage and more risk exposure on the airfield. The US Army is currently in negotiations with Pueblo to house up to thirty attack helicopters at the Pueblo Memorial Airport. Aviation Specific Risk While aviation is an inherently safe mode of travel and commerce it does pose some very unique risks to the firefighting community. The firefighting community has responded to these risks with advents in both technology and tactics. As the field of aviation evolves so must the fire service, identifying these changes are paramount to the safety of the fire service and the general public. Many aircraft have standard equipment that can be hazardous if not dealt with properly. Hazards that exist normally can become even more dangerous in an emergency situation. Familiarization with these hazards is of extreme importance. 42 Fuels All powered aircraft can hold considerable quantities of fuel on board. These fuels may be found in wing tanks and auxiliary tanks in the fuselage. There are two main types of fuel commonly used at the Pueblo Memorial Airport. Aviation Gasoline Aviation gasoline also commonly known as AVGAS and 100LL is an extremely volatile flammable liquid. The flash point of 100LL is about -49°F; it will give off sufficient vapors in any weather condition to form an ignitable mixture in the air, near the surface of the liquid. The vapor flammability limits in air are between one and seven percent; flame spread from 100LL is between 700 and 800 fpm. Auto ignition occurs between 825° and 960°F. The current capacity of 100LL storage at the airport fuel farm is 60,000 gallons. Jet- A Fuel Jet-A fuel is a kerosene-grade fuel used as a fuel in turbine engines. It carries a military fuels designation of JP-5. The flash point of Jet-A is between 45° and 95°F, depending on the mixture. It will mix with air above the flash point and become flammable when the fuel air mixture is just less than one percent. The upper flammability limit is just over 5 percent in air. Auto ignition temperatures range from 440° to 475°F with a flame spread rate less than 100 fpm. The current capacity of Jet A storage at the airport fuel farm is 200,000 gallons. Vehicle Fuels In addition the fuel farm has 600 gallons of unleaded gasoline and 1,200 gallons of diesel fuel at any one time. This fuel is only dispensed into vehicles at the fuel farm and is not placed in mobile fuel delivery apparatus. In the event of a fuel leak both on the airfield or within the tank-farm facility itself the ARFF units assigned to Station 10 would respond and request other assistance as needed. The assistance would come from units in other stations including the assistance of the department hazardous materials team. Tires and Wheels Due to the need to conserve weight in aircraft frequently the wheels on landing gear assemblies are made from magnesium and can become overheated and ignite upon landing. Due to the nature of the wheel construction and the metals used, powdered extinguishing agents are essential on the apparatus. Tire and wheel events would be handled by a response of the ARFF units from Station 10, along with the response of the assistant chief, two engines, rescue/squad and a truck. Each apparatus 43 stationed at Station 10 is equipped with dry chemical systems and extinguishers that could handle these events. Additionally fans from the rescue/squad or truck could be utilized for the cooling of hot wheel events. Ballistic Recovery Systems (BRS) Many modern aircraft, and some modified older aircraft are fitted with on-board parachute recovery systems. These systems are rocket propelled and deploy at over 100mph within 1/10th of a second, leading to severe injury or death to anyone in its path. Due to this BRS equipped aircraft should have the BRS disarmed immediately. To address advents in technology, all personnel assigned to ARFF duty along with the second in engine companies are trained monthly on ARFF topics as required by the FAA. Composites Many of today’s aircraft are built using composites and other lightweight materials. This is to reduce weight of the aircraft thus increasing its fuel economy and performance. When these composites are exposed to fire as in a post-crash incident, toxins can be released as a by-product of the combustion. In addition cutting or fracturing composite skin panels may release hazardous dusts and micro-fibers. Familiarization with aircraft and the recognizing of composites is of extreme importance to firefighter safety. To address advents in technology all personnel assigned to ARFF duty along with the second in engine companies are trained monthly on ARFF topics as required by the FAA. Threatened Aircraft A threatened aircraft would include those that have been hijacked during flight or those that have a bomb threat to them. In these situations the aircraft would be allowed to land and then instructed to taxi to park at taxiway C5, this is in the northwestern corner of the airfield. In the event of a bomb threat without hijacking the passengers will be deplaned and taken at least 500 feet from aircraft involved. As can be seen by the above, the Pueblo Fire Department has plans in place to deal with these unique hazards of the aviation industry and the airfield itself. Aircraft Incidents It is a commonly accepted risk to assume the first arriving ARFF vehicles at an incident involving large amounts of fire will attack the fire with turrets from the trucks; no manpower is deployed for interior firefighting. The theory is to extinguish the fire before the flames penetrate the fuselage; it has been shown, however, this penetration occurs in less than one minute in aviation fires. By meeting the current FAA guidelines of a three minute response, showing extinguishing agent to 44 the mid-point of the longest runway a fire would penetrate the fuselage two minutes prior to arrival of the ARFF apparatus. It is important to note this time is from the time of incident and includes notification by the control tower to the fire station, thus making the placements of stations a priority in emergency planning for the airfield. There is a current call for change to this standard making the three minute response to any point on the airfield; this is a recommended change from the commercial and general aviation communities nationwide and could have wide impact on the ARFF community. 45 Common Aircraft at Pueblo Memorial Airport Beechcraft 1900 No. Of Engines: 2 Aircraft Type: Turbo Prop Passenger Capacity (Max): 19 Cruising Speed (MPH): 303 Payload Capacity (in Lbs.): Wingspan: Length: Height: 4000 54.5 57.9 14.9 Takeoff Weight (in Lbs.): Cabin Type: Fuel Capacity Pounds 15245 Pressurized 4,484 Fuel Capacity Gallons 660 46 Airbus 320 Series No. Of Engines: Aircraft Type: Jet Passenger Capacity (Max): Passenger Capacity (Min): Payload Capacity (in Lbs.): Wingspan: Length: Takeoff Weight (in Lbs.): Body Type: Cabin Type: Pressurized Fuel Capacity Pounds Fuel Capacity Gallons 2 179 164 45,686 111 123 77,000 53,233 7,840 47 Boeing 737 No. Of Engines: Aircraft Type: Jet Passenger Capacity (Max): Passenger Capacity (Min): Cruising Speed (MPH): Payload Capacity (in Lbs.): Wingspan: Length: Takeoff Weight (in Lbs.): Cabin Type: Pressurized Fuel Capacity Pounds Fuel Capacity Gallons 2 189 108 577 29,093 93 94 130,000 46,681 6,875 48 McDonnell Douglas MD-80 Series No. Of Engines: 2 Aircraft Type: Jet Passenger Capacity (Max): 172 Passenger Capacity (Min): 137 Cruising Speed (MPH): 576 Wingspan: 107 Length: 147 Height: 29 Takeoff Weight (in Lbs.): 140,000 Body Type: Cabin Type: Pressurized Fuel Capacity 39,654 Pounds Fuel Capacity Gallons 5,840 49 Lockheed C-130 No. Of Engines: Aircraft Type: Turbo-prop Passenger Capacity (Max): Passenger Capacity (Min): N/A Cruising Speed (MPH): Wingspan: Length: Height: Takeoff Weight (in Lbs.): Cabin Type: Pressurized Fuel Capacity Pounds Fuel Capacity Gallons 4 92 374 133 97 38 155,000 60,000 8,836 50 Bombardier CRJ-700 No. Of Engines: Aircraft Type: Jet Passenger Capacity (Max): Passenger Capacity (Min): Cruising Speed (MPH): Wingspan: Length: Height: Takeoff Weight (in Lbs.): Cabin Type: Pressurized Fuel Capacity Pounds Fuel Capacity Gallons 2 78 2 515 76 106 25 75,000 19,450 2,865 51 ARFF Risk Summary The majority of the air traffic in Pueblo is currently general aviation related. The city does have daily commercial commuter aircraft traffic. There are three flights daily with service to Denver International Airport. The US military also uses the airport for training. These are much larger aircraft and would have greater consequences to the community. However, there are significantly more general aviation operations daily. Many of these operations are conducted by DOSS Aviation, a flight school that provides initial flight screening for the Air Force. Low Frequency Operations High Frequency Operations Low Risk 1-15 Passengers General Aviation Military Flights DOSS Aviation Moderate Risk 16-50 Passengers Great Lakes Aviation Military Heavy Lift Aircraft High Risk 51 Passengers & up 52 U.S. Marshal Prisoner Air Transport – “Conair” Diverted Aircraft from COS and DIA Armed Military Aircraft Chapter 10 Weather Related Risk Winter Storms and Blizzards Pueblo is vulnerable to major winter storms. The city averages 31 inches of snowfall annually, however in the winter of 1989 to 1990 69.6 inches of snow fell. On November 14, 1985 sixteen inches of snow fell. The snowfall along with the high winds causes blizzard conditions at times. The last large blizzard in Pueblo occurred in 1997. This storm dropped large amounts of snow and produced drifts that were several feet tall. This caused traffic to almost totally cease. Winds The City of Pueblo is subjected to winds throughout the year. Many of the wind events have gusts in excess of 70 mph. The winds cause downed power lines and downed trees/branches throughout the city. The downed lines in turn cause power failures which tend to create false fire alarms and stuck elevators. These winds severely affect the Wildland fire risk in addition to damaging structures and trees. 53 Severe Thunderstorms The City of Pueblo has several severe thunderstorms every year with varied amounts of rain, damaging winds, hailstones from pea size to occasionally golf ball and softball size, and frequent cloud to ground lightning strikes. Seven people have been injured and one killed by lightning strikes in the last twenty years. According to Colorado State Hazard Mitigation Plan, Wind and Hail hazards are a moderate hazard for Pueblo. 54 Tornado Pueblo is considered a low hazard risk for tornados. Historically tornadoes have been relatively infrequent in Pueblo County and have not struck urbanized areas. The tornados that have occurred in Pueblo County have been relatively small, weak and short-lived. (Excerpt from Pueblo County Emergency Operations Plan – Annex B – Tornado/Thunderstorm) Source of above three maps was Natural Hazard Risk Assessment for the State of Colorado by: Hazard Mitigation & Vulnerability Assessment Class University of Colorado at Denver and Health Sciences Center In support of: Colorado State Hazard Mitigation Plan, 2004 State of Colorado, Division of Emergency Management Severe Rains/Flooding Pueblo experiences rain storms annually that produce large amount of water over a short period of time. This has resulted in several incidences of street flooding. This flooding has caused entire intersections to be covered with six feet of water or more. These situations typically resolve themselves over time as soon as the heavy rain subsides. The primary risk resulting from these incidents is water rescues from submerged cars, people trapped on top of submerged cars and people swept into storm drains. Pueblo has been susceptible to floods in the past with a series major floods of which the Great Flood of 1921was the biggest. Drought The city has been dealing with drought conditions for several years. The entire region, including Pueblo County, is listed as being in a D3-Extreme Drought by the U.S. Drought Monitor. This 55 indicates that there is “major crop or pasture losses; extreme fire danger; and widespread water shortages or restrictions. The results of the drought conditions can be seen in the Waldo Canyon Fire which occurred about forty miles north of Pueblo in June 2012. This wildfire was the most destructive wildfire in Colorado history killing two people, destroying 346 homes, and consuming over 15,000 acres of land. 56 Weather Related Risk Summary The most common weather related incidents in Pueblo are severe thunderstorms, drought, high wind events, and hail storms. These events are outside of our control for prevention, however we are able to train and equip for the responses. These events typically affect a large portion of the city when they occur. Damage is typically downed electrical lines, downed trees, localized street flooding, and hail damage to house roofs and vehicles. The power lines down create power failures throughout the city which in turn increase the number of fire alarms and elevator rescues. Low Frequency High Frequency Low Risk Weather Event Moderate Risk Weather Event Hail Storms Severe Thunderstorm High Wind Events Drought Winter Storm/Blizzards Severe Rains/Flooding 57 High Risk Weather Event Tornado Chapter 11 CONCLUSION Overall Risk Analysis Summary The primary risks that the Pueblo Fire Department face are EMS calls and single-family residential structure fires (Structure Fire – Moderate Risk). In 2012, there were approximately 11,769 EMS calls. This was approximately 69% of the total calls for service. This is considered a low risk / high occurrence event. The time of day that most of the EMS calls occurred was from 11:00 am to 7:00 pm. The risk analysis process will be an on-going process into the future. All structures are continually being analyzed for fire risk during the annual inspection cycles. There were several moderate risk/low occurrence and high risk/low occurrence risks that were identified. These risks have planned responses for and are often included in the multi-agency county disaster drills. These risks will continue to be monitored for any changes. 58 Low Risk Basic Life Support EMS Wildfire - Grasses – 1 Acre or less High Frequency Fires in Outbuildings or Sheds Fires in Detached Residential Garages Dumpster/Trash Fires Car/Vehicle Fires Elevator Rescue Small Fuel/Oil Spill (Less than 5 Gallons) Antifreeze Spill (Less than 5 Gallons) CO Alarms Moderate Risk Advanced Life Support EMS EMS – Auto Accident w/ Injuries Residential Structure Fire Hail Storms Severe Thunderstorm High Wind Events Auto Extrication Natural Gas Leak (Outside) Residential Natural Gas Leak (Inside) Wildfire – Grasses – (Greater than 1 acre) Aircraft Crash/Fire – Low Frequency Small Aircraft (6 passengers of less) High Risk Confined Space Rescue High/Low Angle Rescue Winter Storm/Blizzards Severe Rains/Flooding Trench Rescue Heavy Equipment Extrication Hazmat Fixed Facilities Incident Large Fuel/Oil Spills Chemical Spills/Leaks Meth Labs Radioactive WIPP Shipments Incidents Commercial Natural Gas Leak (Inside) 59 Multi-Family Residential Structure Fires Commercial Structure Fire Industrial Fires Hazmat Risk Highway Hazmat Risk Rail Fire Involving Hazmat Structural Collapse Swiftwater Rescue Aircraft Crash/Fire – Commercial, Prisoner Transport or Military Aircraft Tornado Explosions Wildfire/Urban Interface – Aberdeen Bluffs Area
