    Area of Science:

    • Occupational Health
    • Dermatology
    • Environmental Health

    Background:

    • Occupational dermatoses are common in construction.
    • Cement and chemicals are frequent causes of skin issues.
    • Prevalence of specific allergens like chromate needs further study.

    Purpose of the Study:

    • To determine the prevalence of occupational dermatoses in a prefabrication construction factory.
    • To identify specific causative agents, including cement, chromate, and rubber chemicals.
    • To assess the prevalence of chromate and cobalt sensitivity.

    Main Methods:

    • Field study involving 272 workers.
    • Interviews, clinical examinations, and patch testing.
    • Testing included chromate, cobalt, nickel, rubber mixes, epoxy resin, melamine formaldehyde, and conplasts.

    Main Results:

    • Overall dermatitis prevalence was 14% (38/272).
    • Cement caused 57% irritant and 39.5% allergic contact dermatitis.
    • Chromate sensitivity was 8.5% (23/272), with 34.8% asymptomatic. Cobalt reactions (17.4%) were linked to chromate allergy.

    Conclusions:

    • Cement is a major cause of occupational dermatitis in this setting.
    • Chromate sensitivity is a significant concern, often asymptomatic.
    • Workplace interventions should address cement exposure and chromate sensitization.
