The Definition of Skin Safety

Definition of Skin Safety

Skin safety is the set of hazard controls, procedures, protective equipment and training used to protect workers' skin from damage and disease on the job. It covers chemical contact, wet work, friction and abrasion, heat and cold, ultraviolet (UV) radiation and biological agents.

The skin is both a target and a route of exposure. Some substances damage the skin directly, causing burns, irritation or allergic reactions. Others pass through intact skin and harm internal organs. Cracked or broken skin lets chemicals in more easily, which is why maintaining a healthy skin barrier is part of skin safety, not just comfort.

Contact dermatitis is the most common occupational skin disease. Most cases are irritant contact dermatitis, caused by repeated contact with water, soaps, solvents, oils and other irritants. Allergic contact dermatitis develops when a worker becomes sensitized to a substance such as epoxy resin, the hexavalent chromium in wet cement, or rubber accelerators in gloves. Once sensitized, even small exposures can trigger a reaction.

Regulations That Shape Skin Safety

• Hand protection, 29 CFR 1910.138: employers must select and require hand protection when hands are exposed to hazards such as skin absorption of harmful substances, cuts, abrasions, punctures, chemical burns, thermal burns and harmful temperature extremes.
• PPE hazard assessment, 29 CFR 1910.132: employers must assess the workplace for hazards, including skin hazards, and select appropriate personal protective equipment (PPE).
• Hazard communication, 29 CFR 1910.1200: skin corrosion, skin irritation and skin sensitization are hazard classes under the Globally Harmonized System (GHS). Section 8 of the safety data sheet lists the protective gloves and clothing needed.
• Emergency flushing, 29 CFR 1910.151(c): where the body may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing must be provided for immediate use.
• Recordkeeping: work-related skin diseases and disorders that meet the recording criteria are entered on the OSHA 300 Log, which has a separate illness column for skin disorders.
• Skin notations: NIOSH assigns skin notations to chemicals that can be absorbed through the skin in harmful amounts. A substance with a skin notation can cause harm even when airborne levels are within limits.

Common Skin Hazards at Work

Chemical hazards

• Wet cement and concrete, which are strongly alkaline and can cause severe burns hours after contact.
• Solvents and degreasers, which strip the skin's natural oils.
• Metalworking fluids, cutting oils and crude oil.
• Epoxies, isocyanates, acrylates and other resins that can cause sensitization.
• Acids, caustics and cleaning chemicals.

Wet work

Frequent hand washing, working with wet hands or wearing occlusive gloves for long periods softens the skin and weakens its barrier. Wet work is a leading cause of irritant dermatitis in cleaning, food processing, healthcare and maintenance.

Physical and environmental hazards

• UV radiation for outdoor workers, which causes sunburn and raises skin cancer risk.
• Heat, which leads to heat rash and contributes to heat stress.
• Cold and wind, which dry and crack the skin and can cause frostbite.
• Friction, abrasion and vibration from tools, materials and poorly fitting PPE.

Biological hazards

Contact with blood, body fluids, animals, plants and contaminated water or soil can cause infections or reactions, especially through cuts and cracked skin.

Controls for Skin Safety

Apply the hierarchy of controls to skin hazards the same way as to any other hazard.

• Elimination and substitution: remove unnecessary chemicals, choose less irritating or non-sensitizing products, and use low-chromium cement where available.
• Engineering controls: use automated mixing and dispensing, enclosed processes, splash guards and long-handled tools to keep hands out of the material. Provide shade for outdoor work.
• Administrative controls: include skin hazards in each job hazard analysis, limit wet work time, provide washing facilities with mild cleansers, and train workers to recognize early symptoms.
• PPE: select gloves by checking the SDS and the glove manufacturer's chemical resistance data. No single glove resists every chemical. Use sleeves, aprons, coveralls and boots where splashes are likely, and replace gloves that are damaged or contaminated inside.

Caring for the skin barrier

A simple skin care routine supports these controls. Workers should wash off contaminants promptly, dry hands fully before putting on gloves, and use fragrance-free moisturizers after work and at breaks to restore the skin barrier. Pre-work creams can make cleaning easier but are not a substitute for gloves.

Research into the skin microbiome, the community of bacteria living on and in the skin, has drawn interest in how it relates to barrier function and conditions such as eczema. Some people with dermatitis-prone skin choose oral skin probiotics as part of their personal routine. This is a personal decision best discussed with a doctor, and it does not replace workplace controls or medical treatment of occupational dermatitis.

Early reporting and health checks

Encourage workers to report redness, itching, dryness, cracking, rashes or blisters early, before a minor irritation becomes chronic dermatitis. Regular skin checks for high-risk groups, along with tracking reports by task, site and product, help identify patterns. SafetyIQ's incident management software helps teams log skin complaints and spot trends.

Example of Skin Safety

A precast concrete plant saw a rise in hand rashes among workers who finished and patched concrete panels. Several workers had cracked, bleeding skin, and two were diagnosed with allergic contact dermatitis from chromium in the cement.

The plant reviewed the task. Workers had been wearing cotton gloves that soaked through with wet concrete, then rinsing with harsh hand cleaner. The plant switched to nitrile-coated gloves with long cuffs, added a wash station with pH-neutral soap near the finishing area, and supplied moisturizer in the break room. Supervisors started a brief weekly skin check, and new cases were logged and tracked. Rash reports dropped over the following months, and no new cases of sensitization were recorded.

Frequently Asked Questions: Skin Safety

What is the most common occupational skin disease?

Contact dermatitis. Most cases are irritant contact dermatitis from repeated contact with water, cleaners, solvents and oils. Allergic contact dermatitis is less common but often lasts longer, because sensitization is permanent.

Can chemicals harm the body through the skin?

Yes. Some chemicals are absorbed through intact skin and can damage organs. NIOSH skin notations and Section 11 of the SDS identify these substances.

Do gloves always protect against chemicals?

No. Each glove material resists some chemicals and not others, and chemicals can permeate gloves over time without visible damage. Choose gloves using the SDS and manufacturer resistance charts, and replace them on a schedule.

Are skin conditions recordable on the OSHA 300 Log?

Work-related skin disorders that meet OSHA's recording criteria, such as those needing medical treatment beyond first aid or causing days away from work, must be recorded in the skin disorder column of the 300 Log.

What should a worker do after a chemical splash on the skin?

Remove contaminated clothing and flush the skin with plenty of water right away, following the first-aid measures in Section 4 of the SDS. Get medical help for burns, corrosive chemicals or any symptoms that persist.
