Molecular Weight of AgentBoth
AgentIsocyanates, flour dust and enzymes, metalworking fluids, rosin based solder fume, wood dust
OccupationWorkers in motor vehicle repair shops (MVR), bakers, workers in electronics and woodworking industries
Outcome/DiagnosisWork-related short latency respiratory disease (SLRD) and asthma
Activity Intervention1. Controlling isocyanates exposure in MVR. 2. Introduction of a maximum exposure limits (MEL) and a workplace exposure limit (WEL) for controlling flour dust. 3. Controlling inhalation exposure to metalworking fluids. 4. Introduction of MEL and WEL for and controlling inhalation exposure to rosin-based solder flux fume (RBSFF). 5. Controlling inhalation exposure to wood dust.
Participation RateNo report of participation rate.
Intervention EffectivenessRatio of incidence rate ratios (RIRRs) for SLRD and asthma: 1. The incidence of SLRD declined significantly for all agents in MVR workers compared to other workers during the intervention period (RIRR: 0.34, 95% CI 0.12 to 0.95). 2. Throughout the period of analysis (1996 – 2010), there was a significant decline in the incidence of SLRD and asthma attributed to RBSFF relative to all other agents (annual RIRR 0.94, 95% CI 0.90 to 0.99, and annual RIRR 0.95, 95% CI 0.90 to 1.00, respectively).
