Occupational dermatitis is a skin condition that develops when a worker's skin is repeatedly exposed to irritating or allergy-triggering substances found in the workplace, such as solvents, cleaning chemicals, cement, oils, or certain metals. The condition can present as irritant contact dermatitis, caused by direct chemical or physical damage to the skin, or allergic contact dermatitis, caused by an immune response to a specific substance after repeated exposure. Symptoms typically include redness, itching, dryness, cracking, blistering, or swelling on the hands, forearms, and other areas of skin left unprotected during work tasks. Because symptoms often develop gradually, workers may not immediately connect a rash or irritation to a specific job task, delaying both diagnosis and the implementation of protective measures.
A construction worker who regularly mixes wet cement without wearing gloves begins to notice cracked, painful skin on both hands after several weeks; an occupational health nurse identifies the condition as irritant contact dermatitis caused by the caustic properties of wet cement and recommends chemical-resistant gloves along with a barrier cream for future tasks.
Common culprits include wet cement, solvents, degreasers, epoxy resins, certain metals like nickel and chromium, latex, and frequent hand-washing or exposure to water, all of which can strip the skin's natural protective barrier or trigger an allergic response over repeated contact.
Employers can reduce risk by providing appropriate chemical-resistant gloves and other personal protective equipment, offering barrier creams, ensuring safety data sheets are reviewed before working with new substances, and training workers to recognize early skin irritation so exposure can be addressed before the condition worsens.
In many jurisdictions, occupational dermatitis that results in medical treatment beyond first aid, lost workdays, or restricted work duty must be recorded on workplace injury and illness logs, so employers should consult applicable regulations to determine spec
