Avoid skin contact. Wear appropriate gloves to minimize risk of injury to skin from contact with dust or physical abrasion from

grinding or sanding.

8.2.3 Respiratory Protection

Avoid breathing of dust created by sanding, grinding or machining. Assess exposure concentrations of all materials involved in the

work process. Consider material being abraded when determining the appropriate respiratory protection. Select and use appropriate

respirators to prevent inhalation overexposure.

Select one of the following NIOSH approved respirators based on airborne concentration of contaminants and in accordance with

OSHA regulations: Half facepiece or fullface air-purifying respirator with N95 particulate filters

. Select and use respiratory protection to prevent an inhalation exposure based on the results of an exposure assessment. Consult with

your respirator manufacturer for selection of appropriate types of respirators.

8.2.4 Prevention of Swallowing

Not applicable. Not an expected route of exposure. Wash hands after handling and before eating.
