Where should signage be posted when establishing a regulated area for asbestos work?

Signage must be posted at all access points when establishing a regulated area for asbestos work to ensure that everyone entering the area is aware of the potential hazards associated with asbestos exposure. This requirement is crucial for maintaining safety as it alerts workers and visitors that they are entering a zone where specific precautions must be taken due to the risk of asbestos. By placing signs at all entry points, it provides a clear and direct message regarding the strict regulations and safety measures in place, which helps to prevent unauthorized access and minimizes exposure risk.

The other locations, like the main office, break room, and near the waste disposal site, do not serve the same purpose. While signage may be necessary in those areas for different reasons, signage at access points specifically addresses the immediate need for awareness and caution among individuals entering the regulated area.
