The most common occupationally related allergens included rubber accelerators, preservatives and bisphenol A epoxy resin. Hands (75.8%), arms (30.0%) and face (15.9%) were common sites of dermatitis.. The most affected occupations were service workers and machine operators.Our cohort may not reflect the general working population.This study identified common occupational allergens, exposure sources, and occupations/industries at risk.
