What?

  • Occupational dermatitis is inflammation of the skin caused by contact with irritant or sensitising substances.
  • Construction workers are at high risk due to exposure to cement, solvents, epoxy resins, and wet work.
  • Irritant contact dermatitis develops from repeated exposure and affects the outer skin layers.
  • Allergic contact dermatitis occurs when the immune system reacts to a specific substance such as chromium VI.
  • Once sensitised, even tiny amounts of the substance trigger a reaction that worsens with each exposure.
  • Symptoms include redness, itching, cracking, blistering, and painful dry skin, usually on the hands.
  • Dermatitis can end careers; severe cases prevent workers from handling any construction materials.
  • COSHH 2002 requires employers to assess skin exposure risks and provide appropriate protective measures.
  • Barrier creams provide a thin layer of protection but are not a substitute for gloves and good hygiene.
  • Health surveillance including regular skin checks is required for workers exposed to dermatitis-causing substances.

Why?

Career-ending diseaseSevere occupational dermatitis forces workers to leave the construction industry permanently, ending their livelihoods.
Very commonDermatitis accounts for a significant proportion of all occupational disease cases reported in UK construction.
PreventableAlmost all cases of occupational dermatitis are preventable with the right gloves, hygiene, and skin care.
Do Don't
  • Wear the correct gloves for the substance being handled every time.
  • Apply barrier cream before work and moisturiser after washing your hands.
  • Wash hands with mild soap and warm water; dry them thoroughly afterwards.
  • Report any skin redness, itching, cracking, or blistering to your supervisor.
  • Attend skin checks as part of the health surveillance programme on site.
  • Read the safety data sheet to identify skin hazards before using chemicals.
  • Change gloves if they become torn, punctured, or contaminated inside.
  • Remove wet or contaminated clothing promptly to prevent prolonged skin contact.
  • Use tools and equipment to minimise direct skin contact with cement and chemicals.
  • Keep your skin clean but avoid harsh scrubbing or abrasive hand cleaners.
  • DON'T handle cement, solvents, or resins with bare hands at any time.
  • DON'T ignore early signs of dermatitis; early treatment prevents it getting worse.
  • DON'T use white spirit, turpentine, or diesel to clean your skin.
  • DON'T wash hands with very hot water or abrasive cleaners that strip skin oils.
  • DON'T wear the same gloves all day if they are wet, torn, or contaminated inside.
  • DON'T assume barrier cream alone is enough protection against chemical exposure.
  • DON'T delay reporting skin problems; sensitisation becomes permanent once established.
  • DON'T share gloves with other workers; contamination transfers easily between users.
  • DON'T kneel in wet cement or allow it to enter the tops of your boots.
  • DON'T skip health surveillance skin checks when they are offered to you.
