6. Personal Protective Equipment
In situations where airborne concentrations of chrysotile asbestos are above the permissible exposure limit (PEL) value, appropriate respirators are mandatory. Workers should be informed of when and why a respirator must be used, and the importance of using it continuously and properly. The correct procedures for the use and verification of protective equipment should be demonstrated.
Respiratory protection must be used only as a temporary measure and should not be adopted as a substitute for engineering controls or other corrective technical measures.
6.1 Evaluation of chrysotile dust level
6.2 Selecting the appropriate respirator
The clean-up of dust and debris which can collect around the equipment should be carried out on a frequent basis using wet sweeping, HEPA vacuum cleaners. Clean-up crews must wear approved HEPA respirators when performing vacuuming operations.
