5 Occupational Dermatitis Hazards and How to Stop Them
More than 13 million American workers face job-related exposures to
chemicals that can be absorbed through the skin, in industries ranging
from construction to health care and food service. The occupational skin
diseases that arise from these exposures can be every bit as debilitating
as occupational lung diseases or severe ergonomic injuries, forcing
workers out of their jobs.
Therefore, you should determine if the five risk factors for occupational
dermatitis exist and must be addressed in your workplace.
What Is Occupational Dermatitis?
Dermatitis occurs when skin becomes inflamed and irritated. The two general types of dermatitis are
primary irritation and sensitization.
Primary irritation usually results from contact with a substance—such as strong acids, caustics,
and solvents—in a significant quantity, concentration, and length of time. This affects the skin
directly at the exposure site in different ways, depending on the type of chemical. For example,
solvents work by removing fats and oils from the skin, while prolonged exposure to oils and waxes
can plug up the skin's hair follicles and sweat ducts, causing inflammation and acne.
Sensitization is an allergic reaction that occurs when the body’s immune system reacts to a
substance. Workers may become sensitized after a single exposure to a substance, or they may be
exposed to a substance for years before their body begins to react.
Identifying Dermatitis Risks
No industry can claim immunity to problematic skin exposures. For example:
• Workers in construction are exposed to Portland cement.
• Healthcare workers are at risk from latex, chemical sterilants and disinfectants, and
hazardous drugs.
• Agricultural workers' skin is exposed to pesticides.
• Many hairdressers are forced out of their trade because they develop skin reactions to the
chemicals they use on their clients.
Any worker exposed to hazardous chemicals in the workplace should be aware of the potential for
skin damage, the dangers of occupational dermatitis, and preventive measures, including wearing
appropriate gloves to prevent contact.
These five factors increase the risk of occupational dermatitis:
1. Frequent or prolonged contact with chemicals. A chemical that might be harmless or mildly
irritating during occasional use can become much more hazardous with frequent or prolonged
contact. Examine the safety information for any chemical that is in contact with workers' skin
frequently or for prolonged periods to ensure that it does not cause skin irritation, sensitization, or
systemic effects.

Also, look for less obvious sources of chemical contact. For example, pesticide residues will linger
on plants, and workers who handle these plants may have significant exposures through the skin
even after the waiting period required following pesticide applications.
Sources of skin exposure include:
•
•
•
•
Direct contact with contaminated surfaces
Aerosolized particles
Immersion
Splashes
2. Skin that is already damaged. Intact skin can protect against many exposures, but damaged skin
may permit chemicals that would otherwise be blocked to enter the body.
Employees who work with chemicals that pose a skin hazard should be aware of whether they need
to take additional precautions when they have scratches or cuts on their skin. Under some
circumstances—for example, workers with large open wounds that could come into contact with
chemicals—they may need to be temporarily reassigned.
Workers exposed to mechanical hazards, such as friction, pressure, abrasive materials, or sharp
edges, can suffer skin damage on the job that will make chemical exposures much more dangerous.
Make sure chemical exposure hazards are not compounded by trauma hazards in the workplace.
3. Poor hygiene. Workers with dermal exposures should wash frequently so chemicals do not
remain on their skin for long periods of time. Skin hygiene in the presence of hazardous chemicals is
somewhat different from skin hygiene at home. Workers should:
•
•
•
•
Wash their hands before putting gloves on so they do not trap hazardous materials against
their skin.
Wash their gloves before removing them so they do not transfer hazardous chemicals from
the gloves to their skin.
Wash their hands after removing contaminated gloves, and dry their hands gently, but
thoroughly.
Use only moisturizers provided by the employer that will not damage gloves, and apply
lotions and moisturizers only to clean skin.
Note: If pH is an issue (as it is for workers who use Portland cement), employers should provide pH
neutral or buffered soaps at work, and workers should also use them at home.
4. Temperature extremes or exposure to sunlight. Heat and cold both stress the skin, making it
more susceptible to chemical injury. Sunlight, too, can make some exposures more dangerous
through its interaction with chemicals.
5. Wet work. A chemical that might not ordinarily penetrate the skin in large amounts could do so
under wet conditions—including heavy perspiration—because wet skin is more permeable than dry
skin. Workers in wet environments may need to take precautions—such as wearing gloves—that
would not be necessary if their skin were dry.
Tip: Workers who use solvents, such as methylene chloride, may be tempted to clean their skin with
it. Teach them about the hazards and to clean their skin with soap and water only, rather than with
potentially hazardous solvents.
