Occupational dermatitis is common in construction workers. Patch testing revealed chromate as the primary allergen, followed by cobalt, nickel, epoxy resin, and rubber components like thiuram mix.

Area of Science:

  • Occupational Dermatology
  • Allergology
  • Environmental Health

Background:

  • Occupational dermatitis is a significant concern for construction workers.
  • Identifying causative allergens is crucial for prevention and management.

Purpose of the Study:

  • To analyze patch test results in construction workers with suspected occupational dermatitis.
  • To determine the prevalence of specific allergens in this cohort.

Main Methods:

  • Patch testing was performed on 449 construction workers presenting to an occupational dermatology service.
  • Data collected between 1989 and 1993 included patient history, clinical presentation, and patch test reactions.

Main Results:

  • 65.5% of tested workers showed work-related positive reactions.

  • Chromate (42.1%) was the most frequent allergen, followed by cobalt (20.5%), nickel (10%), and epoxy resin (7.5%).
  • Sensitization to rubber components, particularly thiuram mix (23.7%), was observed in 25.9% of patients.

    • Conclusions:

    • Chromate and cobalt are major allergens causing occupational dermatitis in construction workers.
    • Rubber components, especially thiuram mix, are also significant sensitizers in this industry.
    • Targeted allergen avoidance and improved safety measures are necessary for affected workers.
