Engineering Controls:
Use adequate general or local ventilation to keep airborne concentrations below the exposure limits.
Personal Protective Equipment:
Respirator: NIOSH approved respirator for toxic dust. The respirator selected must be based on contamination
levels found in the work area. Supply air respirator with full‐face piece.
Immediately Dangerous to Life or Health Conditions: Self‐contained breathing apparatus operated in
pressure‐demand or other positive pressure mode.
Skin and Eye Protection: Wear appropriate protective clothing and equipment to prevent repeated or
prolonged skin contact. Wear appropriate gloves to prevent contact with substance.
Eye Protection: wear splash proof or dust resistance safety goggles to prevent eye contact with this
substance.
