8 – EXPOSURE CONTROLS AND PERSONAL PROTECTION

No occupational exposure limits have been established for bauxite. This material is a particulate matter and adequate inhalation/respiratory protection should be used to minimize exposure. The exposure limits for Exposure Limits Particulates Not Otherwise Regulated (PNOR) are applicable. OSHA (PEL) 15 mg/m3 (TWA, total particulates not otherwise regulated); 5 mg/m3 (TWA, respirable particulates not otherwise regulated).

Provide local exhaust or process enclosure ventilation system. Ensure Engineering Controls compliance with applicable exposure limits.

Wear appropriate Personal Protective Equipment (PPE) to minimize Personal Protection exposure to this material

If workplace conditions warrant respirator, wear adequate respirators Respiratory Protection against dust when handling the material.

Eye / Face Protection Wear splash resistant safety goggles with a face shields. An eye wash station should be readily available near areas of use.
