Exposure controls.
IMPORTANT:
1. Use of employee rotation to control exposures is not advisable since inorganic arsenic is a known carcinogen.
2. Respirators and other personal protective equipment (PPE) do not substitute for feasible exposure controls.
You must use feasible exposure controls to reduce exposures to or below the permissible exposure limit (PEL), or as low as achievable.
