RESUMO
OBJECTIVE: To test the feasibility of collecting reliable and representative data on exposure of Belgian employees to a selection of hazardous chemicals by using a sentinel surveillance method. METHOD: In PROBE (Hazardous chemical Products Register for Occupational use in Belgium), 47 occupational physicians were recruited as a sentinel network. Employees answered a web-based survey assessing their past week exposure to 22 chemicals. RESULTS: 47% employees were exposed to at least one chemical. The most frequently reported exposures was to diesel exhaust (14%). The exposed employees were mostly older men, with most exposed during production and manufacturing, and working in smaller companies. For diesel exhaust, wood dust, and crystalline silica, 54%, 32%, and 20% of the exposed employees, did not use collective/personal protective equipment. CONCLUSION: Sentinel surveillance is a feasible method for obtaining high-quality data on the exposure of Belgian employees to hazardous chemicals.
