How can asbestos exposure be reduced on a worksite?

To effectively reduce asbestos exposure on a worksite, utilizing engineering controls and proper personal protective equipment (PPE) is crucial. Engineering controls involve implementing systems that are designed to minimize the release and inhalation of asbestos fibers into the air. This can include using enclosed workspaces, local exhaust ventilation, and other measures that directly target the source of asbestos exposure.

Proper PPE is equally essential, as it provides a barrier between the worker and hazardous materials. Specifically, respirators designed for asbestos work filter out harmful fibers, while protective clothing prevents skin contact and reduces the risk of bringing fibers home on clothing. Combining these two strategies helps create a safer work environment and significantly lowers the risk of exposure to asbestos.

Other options, such as increasing the number of workers on site or eliminating work-related activities, do not effectively address the core issue of exposure to hazardous materials. Additionally, shortening work shifts may help reduce exposure time, but without addressing engineering controls and appropriate PPE, it does not provide a comprehensive solution to the hazard posed by asbestos.
