GRT Safety Manual
GRT Safety Manual Philosophy One accident is one too many. Here at GRT, we believe that safety and good engineering come hand in hand. We follow the mindset that “The best engineers are safe engineers.” It is imperative that we maintain a zero-accident streak, or else we may lose our shop and ability to compete in the FIRST Robotics Competition. More importantly, that accident could cause a serious injury or death to a student, resulting in life-long consequences. Engineering Technology and Robotics Team Safety Program at Gunn High School Training Program: 1. Our Safety training begins each year before school starts. Experienced students who have already been on the team for a year or two meet with instructors to develop usage and safety documents for each tool. At the same time, the students have their own safety habits refreshed by industry professionals. This process is effective because students in the group feel ownership and responsibility for the safety program. The most current documents are included. 2. Each student must go through thorough safety training before he or she is allowed to use shop tools. The program includes: a. Safety Discussion. For an entire class period, students and the instructor talk about safety rules and –more importantly- the attitude of safety. We discuss possible dangers of tools, procedures to avoid injury, the location of fire extinguishers, electrical panels and first aid kit. b. During a subsequent shop tour, students discuss safety issues and proper procedures with each tool, so that the previous topics are reinforced in front of the tool talked about. c. Students are trained by the experienced members who went through summer training. Under their supervision, and that of a watching mentor, students receive the proper instructions, and then machine a small project piece out of aluminum. This piece shows them the potential they have to create, and serves to remind them of the proper safety techniques the learned. d. Students take a written quiz on the safety and operation of each tool before they are certified to use it. All students in the shop are required to receive 100% before they can use the power tools in the shop. Accident Prevention: 1. A certified teacher is on site whenever students are working in the shop. 2. Additional adult mentors and parents are often on site during our intense build periods. The adults have gone through the proper safety training, and are aware of the procedures to be taken in case of an emergency. 3. Tools are well-maintained, and students know to report any unsafe conditions. 4. Our training program stresses safe attitudes, and students know that they can ask questions before they start work. Engineering Technology and Robotics Team Safety Program at Gunn High School In the Event of an Accident: 1. Students are required to inform the instructor, who will respond with the appropriate First Aid and/or emergency calls. Many students are also certified First Aid practitioners, as required by the district. Emergency numbers and parent contact information on file at all times. MSDS safety sheets and First Aid kits are also in an accessible location for any chemical spills. 2. The entire shop is shut down and will not reopen for 24 hours PLUS any additional time required to fix any unsafe conditions and review safety procedures with the entire team. Gunn High School Safety Regulations and Shop Policies 1. Safety Glasses are to be worn at all times. 2. Students shall not operate machine tools while wearing long sleeves, lose clothing, neckties or jewelry (wristbands, long earrings etc…) 3. Ih is highly recommended that you have short hair when operating machine tools. All students with long hair are required to tie their hair back. 4. Do not operate any machine tool unless you are thoroughly familiar with it. 5. Check machine speed setting before starting machine to assure spindle is not started at an unsafe speed. 6. Do not leave machine unsafe for the next person. Turn off power whenever you leave a machine. 7. Do not wear use gloves when operating machining tools. 8. Chuck jaws shall not extend so far out of the scroll that they will become sprung or dangerous under cutting pressure. 9. Stock should be cut to shorter lengths. Long lengths of stock extending beyond a lathe spindle must be supported to prevent whipping. 10. Never let the chuck key leave your hand unless you are putting it down. Chuck keys left in the chuck can become dangerous projectiles. 11. Do not block narrow aisle ways, fire extinguishers, or electrical panels. Nothing shall be placed within three feet of fire extinguishers and electrical panels. 12. Cover ways on equipment when sanding or grinding. 13. Work cannot be held by hand when drilling. Clamp and secure it properly. 14. Do not attempt to lift heavy objects alone. Get help or use a hoist. 15. Work or material stock should be placed on the floor, workbench, or machine in such a manner that no one can be injured by it. Return stock to the stock room as soon as you are done with it. 16. It is the responsibility of each student to clean up after themselves. Remove all chips, oil and residue from the machine including the chip pan by the end of the class, or when done using the machine. No machine will be left dirty. Chips around the machine will be swept up and vacuumed by the student. 17. Do not dispose paper towels, or paper products in chip pans, use a trash receptacle. Gunn High School Safety Regulations and Shop Policies 18. Use a a hook or rake when removing chips from work or chip pans, and only when machine has stopped running. 19. Any slipper substance such as oil, grease, water, etc. spilled on the floor must be wiped up immediately. Use sawdust to soak up oil, and then sweep it up. 20. Do not leave waste material or refuse lying around, put them where they belong. 21. Use common sense to protect yourself and others around you from possible injury by carelessness. 22. PRACTICAL JOKES, HORSEPLAYM THROWING OBJECTS, AND AIR HOSE GAMES ARE PROHIBITED. 23. Report any unsafe or hazardous conditions to your instructor immediately. 24. Do not alter or modify any equipment. 25. Machining of magnesium or other flammable or toxic materials is prohibited. 26. Never attempt to make electrical repairs yourself. Notify the instructors so he or she can call an electrician. 27. Pedestal Grinders a. One operator at a time only. b. Stand aside when starting and dressing wheel. You must wear a face shield when dressing a wheel. c. Make sure tool rests are adjusted correctly, and are not too far from or too close to the wheel. d. Only steel is to be ground on the grinder. If it doesn’t spark, don’t grind it. Shop Renovation As an elder team that participated in the very second year of the FIRST Robotics Competition, the Gunn Robotics Team has had fantastic facilities to support its students and their passion. However, over the past few years, our mentors have noticed that the much-loved 50-year-old buildings that housed our team’s infant years have started to show their age and have turned into a less than optimal working environment. After petitioning the school district for over a year, our mentors successfully secured a $15 million grant to renovate our entire technology building. So last year, our shop was completely fixed up with a series of improvements to keep the students safe. To begin with, our entire electrical system was revamped from our antique wires to new ones capable of the strain placed by our powerful machining tools. This resulted in a safer shop better equipped to support our team. In addition, outlets are placed above workspaces on retractable cords, so there are no “trip” wires snaking across the floor or dangling down from the ceiling when they are not being used. As part of the upgrade, we also received a centralized vacuum system to aid in the maintenance of our shop. The vacuum stops dust from flying into the air when we sand wood and aluminum, and makes nightly clean-up much easier. Instead of using dustpans, which do not adequately collect fine dust produced by our machining, we simply sweep the chips into a vacuum vent and “Woosh” it disappears. Every few months, the outside receptacle is emptied. Also, it includes a HEPA filter to reduce the amount of fine dust particles in the air in our shop which we breathe. The remodel also included a new floor for a new shop. Gone was the previous cracked concrete that swallowed nuts and bolts, and in came the smooth new floor. It improved cleanup endlessly and made the shop a much nicer place to practice driving our robot. The floor was also coated with a special non- slip coating that makes cleanup of spilled liquid easier, yet prevents students from slipping. The school district also installed new, brighter fluorescent lights lights to replace the old metal halide bulbs of the last century. These new lights start up instantly, avoiding the five-minute wait that the old lights would need to reach full brightness. Also these new lights are considerably more energy efficient, enabling us to help meet our schools goal of more energy conservation. Shop Safety In order to maximize our time to work, but also make sure we have the safest time possible, our mentors sacrifice their evenings to take shifts to watch over the team. They organize these shifts themselves, and come in at least once a week to take their turn. Keeping our machinery in working order is an essential component for proper shop safety. We replace cutting and abrading equipment such as bandsaw blades, sanding discs, and sanding belts as needed to maintain a sharp cutting edge, which reduces the risk of accidents from using dull equipment. To keep the shop safe, our team also has a system of dealing with hazards and broken tools. Students immediately report any problems they have or broken machine tools to one of our mentors, because they know that the mentors will not start yelling at them. Once a broken toll or other hazard has been reported to one of our mentors, the hazard is marked off and the tool power switch “Locked out and Tagged Out” so that nobody can use the broken tool, until it has been professionally repaired. A common mantra at home is to “wash your hands before every meal.” Here at GRT, we take it a step further. To avoid painful metal splinters and just to keep our hands clean, we use industrial strength pumice hand soap to rub off the stickiest greases and the sharp chips. Cleanup is also a large part of our philosophy. It is impossible to maintain a safe shop without a clean shop. Tools scattered on the tables and stock on the ground is a sure way for people to injure themselves. This is why we make sure to spend at least half an hour every night making sure we are ready for the next day. We also take time after each major deadline to clean our home and boost efficiency. We know that access to the shop is a privilege, and we ought to maintain it to the best of our abilities. This sign on the wall humorously reminds us to keep our shop clean. Safety for our visitors is also an utmost priority. Though we try to halt machining whenever we have guests in the shop, we provide them with ANSI certified safety glasses to keep them safe. Not only is this proper safety protocol in our shop, we also want to reinforce safe habits so that whenever they visit another team or machine shops, they will remember to wear safety glasses. Fire is a hazard that we are trained to deal with. Firstly, we try to prevent fire by machining at safe speeds, and by This sign adorns all entrances to the shop so visitors and students alike remember to protect their eyes. Shop Safety keeping all flammable substances in a sealed cabinet away from the power tools. In addition, we keep multiple type ABC Fire Extinguishers around our shop and main classroom in strategic locations such as near exits and near the welding equipment. In case a fire ever breaks out, students will be able to use these extinguishers to fight the fire. Also, overhead fire sprinklers will turn on if they detect a large amount of heat. By this time, the students will have evacuated to our outdoor field as part of the school’s emergency fire protocol. Toxic fumes are another hazard of a machine shop. Our controls team uses lead free solder and non-toxic flux in their cubicle, with a fan blowing the fumes out the window. The paint room is equipped with industrial respirators for anyone who enters the room, as well as a paint spray booth so that the dangerous fumes are sucked away. This is the same for the welding room, where another industrial ventilation system helps remove the argon dioxide and other toxic gasses that are by products of the TIG welding process. The ventilation system in this room also helps to cool the newly welded parts rapidly so students are not burned by mistakenly touching hot metal parts. To keep all of us alert to the destructive capabilities of a machine tool, lists detailing safety tips and possible hazards are posted where the machinist can see. Before even starting the tool, the student operating it is reminded to check that chuck keys or other adjustment wrenches are removed, and that the workpiece is secured properly. We hope that these reminders will minimize the possibility of having an accident in our shop. Before we are allowed operate the machine tools by ourselves, all students must pass the shop safety test with a score of 100%. This comprehensive examination ensures that everyone knows how to operate the power tools safely, and that everyone in the shop knows how to keep it safe. Safety does not pertain to the shop alone; it is a philosophy we adopt in every aspect of our life. We know that sick and tired students do not make a good team, so we make sure to get a good night’s sleep and rest every day. During the build season, when parents take turns bringing food for the team, they know always to bring salad and fresh fruit, healthy options that contain many needed vitamins and minerals. In addition, we follow the “one cutie a day” rule to provide the necessary boost in vitamin C. Since 50 or so students are working at the same time in a room, these measures are necessary to make sure one person does not get the entire team sick. Student-Implemented Safety The Gunn Robotics Team Safety Program believes that teaching safety is not enough; its team members must have a philosophy of safety. This philosophy motivates students to keep the shop clean without anyone asking them, and also inspired the following improvements. Whether for wiping up spills or simply cleaning off a finished piece, shop towels are in integral part of shop operation. However, the bulky boxes that contain them do not fit well on the worktables near the tools. To remedy this problem, students spent their free-time after school creating simple fixtures that could hold the boxes close at hand, but out of the way. We believe in working to make our shop a safer environment. Over the summer, two students also took it into their own hands to write a machining manual that highlighted basic functions of a machine and the dangers it posed. These serve both as an introduction for our rookies, as well as a handy resource for explaining each machine to visitors. In addition, we have complete safety manuals written by students for each tool which expand on the machining manual by elaborating on specific safety rules for each tool. In addition, they offer tips holding stock correctly and maintaining the machine. Mentors read over these documents to ensure that they are accurate. Before school starts, our safety captain also makes sure our safety cabinet is fully stocked and prepared to meet any emergency. This cabinet is located right by our shop and holds First Aid kits, work gloves for lifting sharp objects, safety glasses for visitors, hearing protection, and hairbands to keep long locks out of the way. First Aid kits are also kept up to spec and restocked every year. After receiving Platt’s safety bag this year, we further implemented our own kit with larger gauze strips and cleaning pads. We make sure that no matter what incident, students licensed to perform First Aid, and the instructor present will have what they need to address the problem. Since the best engineers are also artists, students spent time over the summer drawing up beautiful posters they put up around the shop to remind us of safety rules all throughout the rule. To keep our shop clean, we also added trash and scrap bins by each tool at the beginning of last year. This way, chip removal is a simple matter of scooping it into the nearest red bin, while wood and plastic scrap get tossed in the black bins right next to it. These improvements all serve make our shop a safer place, but the greatest measure we take is our cleanup sessions. After every major step in the design and build process, we spend most of a day making sure our shop looks presentable, and remains a safe place to work. This extra session is in addition to cleaning up every night, and students cleaning up when they are done with a tool. With these sessions, we make sure tools are where they belong, so we can work more efficiently because things are easier to find. Outreach Students on the Gunn Robotics Team know that an important part of the team’s agenda includes helping the community. Throughout the year, we have many outreach programs to not only spread the news about FIRST and get kids interested in science, but also to promote safe habits to those they meet. One of our largest demonstrations each year is the Haunted House. 4th and 5th grade students from local elementary schools come to work on designing a haunted house with GRT members. The kids come up with the ideas, design a mechanism that is powered by a single pneumatic actuator, then GRT students help actualize their dream. While the elementary-schoolers are here, we make sure to emphasize the safe habits necessary we practice in our shop, especially wearing safety glasses and closed-toed shoes. Furthermore, we make sure that they are “machining” safely when they cut cardboard and balsawood to during prototyping. They are given safety glasses to wear, and are carefully instructed on how to saw wood correctly before they attempt it themselves. Another large outreach program at GRT is our sister FLL team. This team consists of a 4th grade Girl Scout troop from a nearby school that visits once a week to work on their competition. While they are here, our mentoring students are extra careful in escorting them when they walk through the shop, and make sure the girls are properly protected with glasses, closed-toed shoes and pony-tailed hair. To fundraise this year, we also had the opportunity to work Stanford football games by making and selling concessions. Outside our shop, especially by a deep fryer, we were especially wary of following the safety protocol required by Stanford Concessions. Aprons protected against small spills while gloves kept the food clean. We also visit the local middle-schools that feed into Gunn High School to interest the students there in science, and to explain what we do. Whenever we do presentations, we make sure to always emphasize the dangers of the machine shop, so that the students would be careful and less likely to injure themselves. We make sure that at all public presentations, such as the one we hosted for the National Science Teachers Association last year, we follow the same rigid protocols as in the shop, so that we can promote safe conduct wherever we go. Emergency Travel Procedures Away from the comfort of home, a set protocol for any unforeseen emergency is critical. To avoid most problems with people getting lost, try to follow the time schedule as well as possible, and always walk the streets with at least one buddy. In the case that something dangerous happens in the arena, the rendezvous point is at the plaza at the intersection of West Baltimore Street and Hopkins Plaza. This is about halfway between the arena and our hotel, and is by the corner of the 1st Mariner Arena. Once there, we wait until one of our supervisors of the trip come and release us. This way, no one will wander off in the confusion and get lost. It also allows the supervisors to see if anyone is missing, and to watch over the rest of the group more conveniently. Emergency Contact Info First Last Parent/Guardian 1 Phone 1 Parent/Guardian 2 Phone 2 Mentors Since its infant years, the Gunn Robotics Team has been supported by many industry professionals, some parents, some from our sponsors, but all kind-hearted men and women who sacrifice their time to instruct and watch over us. Gunn Robotics Team would like to take this space to thank them and acknowledge their contributions to helping us be the best we can be. Name Bill Dunbar Company PAUSD, Previously at Lockheed Martin Karl Van Dyk SRI International Seth Mallory Valley Transit Authority Ofer Bruhis B&G Systems Sebastian Bersch The Techshop Dale Jordan Linde Group Brian Hatchtman Tesla Charlie Mayman Controls Expert Kevin Young GRT Alumni, Mechanical Engineer Steve Jacobowsky Restoration Robotics Introduction This is our teacher. Diligently watching over team ever since he founded it in the second year of the First Robotics Competition, Mr. Dunbar can be counted on for a good laugh or a solid insight into design. An expert machinist, Karl is a great blessing to our team. Look to him for machining tips, and advice on making tricky parts. Seth is a friendly mentor who has been with the team for many, many years. He has a knack for common sense, and can be relied upon for advice, whether for design, or for game strategy. He also has experience with emergency medical response, and has been a safety inspector at past FIRST events. A supportive parent of his three sons who all passed through GRT, Ofer has a knack for good ideas and is a good place to start with design questions. Seby is a GRT Alumni, and worked at the Techshop, a YMCA for machinists. He is very careful about safety, and tries to make sure our shop is as safe as possible. If you have a difficult part that needs to be made, ask him for protips. This professional welder comes in to instruct our small welding team, and to certify that they are using the stations correctly. If there are any malfunctions with the machine, he is also the first person we go to. Brian is a new mentor this year from Tesla. With his experience in the electric car industry, he provides good insight for optimizing our battery-powered robot with its electric motors. Father of one of the most distinguished welders on the team, Mr. Mayman is great resource and advice-giver to our controls group. They know he will have good insight into their wiring and code for the robot. A GRT Alumni of 2008, Kevin attended UC Berkeley and has a degree in mechanical engineering. Since he knows how FIRST games have traditionally been, he gives good advice on how the game will be probably play out. Steve is a master CNC’er who specializes in unique parts used for medical applications. Be sure to ask him questions about CNC and CAM while he is here. No Green, No Machine There are many steps before team members can use the machine tools by themselves. Students first engage in a full-team discussion on safe etiquette and behavior in the shop, and then go through hands-on training under the guidance of those who came in for the summer certification with our mentors. Lastly, to confirm that they are ready to work safely by themselves, students must pass a safety quiz with a score of 100%, since any mistake could be exponentially worse in the shop. Students all receive basic training and must pass the quiz. If they are willing to spend the extra time and energy, they can also learn to CNC and Weld from a mentor. Tom Jacobowsky from Restoration Robotics is the local CNC expert, while Dale Jordan from the Linde Group comes by every year to certify our welders.

Drill Press: A vertical chuck holds drill bit to make holes in a clamped material. It can be used on wood, plastic, aluminum and steel. Clamp the piece in and make sure the vice is secured to the table. Make sure to use a pin punch or center drill to make sure your hole is in the correct position. Put the bit in the chuck, and make sure to use the key to tighten the chuck at more than one hole. Turn the drill press on, check to see you have the proper spindle speed for the material you are drilling, and slowly lower the spinning bit. When machining thick stock, peck in and draw out to avoid excessive heat and chip buildup. Clean up afterwards so the tool is ready for the next person to use. Mill: A collet system holds endmills to cut slots and drill holes in precise locations in a piece. It can be used on wood if the dust is vacuumed away, plastic, aluminum, and steel. Clamp the piece in the securely. Select the correct R8 collet for your endmill, and slip it into the mill. Hold them up while you tighten the drawbar on top. When it is hand tightened, use the spindle brake and a lever to turn the drawbar another half-rotation. The power switch is at the top right. Before you cut, make sure that the spindle is spinning in the correct direction, typically clockwise, and that the spindle is turning at the proper speed for the material being machined. Use the quill to control the z-axis, and the two handles to control the x and y axis. Lathe: A collet or chuck holds the piece in the spindle. Turning, parting, boring and drill bits are used to shape cylindrical material. Make sure the piece is in securely. Drop the bit holder in, making sure that it is exactly halfway down the piece along the zaxis. Turn the machine on, making sure the piece is turn counter-clockwise when viewed opposite the spindle. Use the knobs to carefully control x and y movement of the bit. Machining Manual Vertical Bandsaw: A long blade is strung between two pulleys, and cuts moves in a constant downward motion to cut material. Turn machine on and slowly push stock along table. Be very careful that your fingers are out of the way. If it is a small piece of material, use a bar or larger piece of stock to guide it. Horizontal Bandsaw: Similar to the vertical bandsaw, but the saw moves slowly downward to cut through a clamped piece. Clamp your piece down. Add oil and turn the machine on. Reach under the hydraulic and turn the valve slowly until the saw moves slowly and steadily downwards. After the machine turns itself off, turn the valve off so the machine is safe for the next person. Disc/Belt Sander: Sandpaper is spun at high speeds to take material off parts quickly. Open the vacuum vent connecting to the sander and then turn the machine on. Slowly push your piece towards the sandpaper. Be very careful that your fingers are out of the way. If the piece is small, use vice grips or pliers. Grinding Wheels: Wheels of Silicon Carbide spin at high speeds to grind steel and sharpen lathe tools. Only grind steel; aluminum will clog up the wheel. If there are no sparks, don’t grind it! Have a cup of water handy in the holder by the machine. Turn the machine on and rest the piece against the table. Slowly brush the part against the wheel with a steady even pressure. Be sure not to just grind in one place, as that leaves notches in the wheel. Also dunk the piece in water every few passes to keep it cool. Nylon and Buffing Wheels: Similar to the grinding wheel, but this machine uses a nylon and a felt wheel for removing burrs from and for polishing aluminum. Grip the piece tightly, use pliers or vice grips if it is small. Turn the machine on and slowly brush the edge that needs to be finished against the wheel. Be sure keep moving as to avoid notches in the wheel. The piece should be contacting just below the center of the wheel in case you lose control of your part. Machining Manual Overview: Tool Hand Drills Drill Press Mill Lathe Vertical Metal Bandsaw Vertical Wood Bandsaw Horizontal Bandsaw Chopsaw Panel Saw Disc/Belt Sander Grinding Wheels Nylon and Buffing Wheels Hole Punch Shear Sheet Metal Benders Arbor Press Hydraulic Press Wood Lathe Description Press the trigger to make the bit spin. Used for drilling and screwing. A vertical chuck that uses drill bits to make holes in a piece. Similar in concept to the drill press, this machine features a collet system for holding endmills, and a movable table for more versatility. For this tool, the stock is put inside the chuck or collet, and is spun at high speeds. The part can then be turned down, drilled or bored out, or parted off. The name says it all. A long saw blade is spun around two pulleys. It’s small teeth can handle metal stock better. Like the above, but with larger teeth to cut through softer materials. This saw also has a long looped saw blade, but swings down to cut stock that is clamped. This is more useful for cutting stock with larger diameters. A rotating circular saw blade cuts smoothly down as you bring the handle down. Different blades allow you to cut different material. A rotary saw rests in a housing that slides down rails to cut large sheets of wood that rest vertically. Rotating discs or bands of sandpaper allow this tool to finish off other pieces. It can do angles and curves with ease. These wheels slowly grind down steel to sharpen or clean steel. This is especially useful for maintaining lathe bits. Don’t use if the material does not spark! Similar to the above, but for finishing parts. The nylon wheel removes sharp burrs from outside edges, while the buffing wheel polishes the piece. Just its paper counterparts, but capable of punching through metal. This is much faster and cleaner than drilling. Similar to the hole punch, this tool relies on a foot pedal to shear through sheet metal, hence its name. It allows for faster and straighter cuts than the bandsaw. Another sheet metal tool, a set of teeth hold the stock down while you lift the lever to bend it to the desired angle. This tool features a long lever that drives a ram down. It is the favored method for press-fits, since you have tactile feedback. Similar to the arbor press, but powered by hydraulics. This tool can produce many tons of force, and is better for slow steady applications, such as for broaching. Similar to the metal lathe, the wood lathe spins wood stock to be Materials Wood, Plastic, Aluminum, Steel Wood (with a vacuum), Plastic , Aluminum, Steel Plastic, Aluminum, Steel Aluminum, Steel Wood, Plastic Aluminum, Steel Wood, Plastic, Aluminum, Steel Wood Sheets Wood, Aluminum, Steel Steel Aluminum Sheet Aluminum or Steel Sheet Aluminum or Steel Sheet Aluminum or Steel Wood Machining Manual Centralized Vacuum System CNC Mills Mini Machines Welding Stations Pneumatics shaped by the use of handheld chisels. This system keeps the dust out of the air when material is sanded, and deposits chips outside in a collection bin. Like the normal mills, these machines are computer controlled and can cut intricate designs. They are programmed using G-Code and Cam software. This collection features a miniature lathe, CNC mill and drill press. They operate the in same way as their larger counterparts with less power, so they are limited to softer materials. T.I.G and M.I.G welding stations melt like metals together with the use of high currents, forming strong bonds. Similar to hydraulics, pneumatics use compressed air to move a piston in an out. This actuator allows for very simple mechanisms that require linear motion. Wood (vacuum), Plastic, Aluminum, Steel Wood (vacuum), Plastic, Steel Aluminum, Steel
