What should be done if fiber levels exceed the OEL during moderate-risk abatement?

When fiber levels exceed the occupational exposure limit (OEL) during moderate-risk abatement, it is imperative to halt work until the situation is addressed and corrected. The rationale behind this response is rooted in safeguarding both worker health and regulatory compliance. Exceeding the OEL indicates a potentially hazardous situation where workers may be exposed to unsafe levels of fibers, which could lead to serious health issues.

Stopping work allows for immediate intervention measures to be implemented, such as reassessing the control measures, enhancing protective equipment, reviewing ventilation systems, or modifying work practices. This action not only protects the workers from potential health risks but also demonstrates a commitment to maintaining a safe work environment, fulfilling legal and ethical responsibilities as set by health and safety regulations.

Continued work despite high fiber levels presents the risk of prolonged exposure, leading to adverse health effects. Therefore, it is critical to prioritize worker safety by pausing operations until effective corrective actions are taken.
