Which of the following methods is NOT specified by WISHA regulations for controlling airborne asbestos exposure?

Limiting work hours is not specified by WISHA (Washington Industrial Safety and Health Administration) regulations as a method for controlling airborne asbestos exposure. WISHA focuses on effective engineering controls, administrative practices, and personal protective equipment to minimize risk in environments where airborne asbestos may be present.

The other methods listed are actively endorsed by WISHA to reduce the risk of exposure. Using local exhaust ventilation is a critical engineering control that helps capture asbestos fibers at their source, thereby reducing the concentration of airborne asbestos. Providing protective clothing is essential to prevent skin exposure and contamination when working in areas where asbestos is present. Conducting regular inspections helps ensure that control measures are functioning effectively and that the workplace remains compliant with health and safety standards. Therefore, while limiting work hours may contribute to overall occupational health practices, it is not a direct method outlined in WISHA regulations for controlling asbestos exposure.
