For workers performing Class I or Class II work, how often must personal air monitoring be conducted?

Personal air monitoring for workers engaged in Class I or Class II asbestos work must be conducted daily to ensure that any exposure to airborne asbestos fibers is accurately assessed and managed. Conducting monitoring on a daily basis allows for the identification of potential respiratory hazards in real-time, providing crucial data to inform safety measures and compliance with exposure limits set by regulations. Daily monitoring helps protect workers from the severe health risks associated with asbestos exposure, such as lung cancer and asbestosis.

In contrast, less frequent monitoring could lead to inadequate awareness of exposure levels and possible health risks, hence the requirement for daily monitoring in these high-risk work classifications. This regular assessment ensures that necessary controls can be implemented promptly to minimize exposure and enhance worker safety.
