8. Exposure controls/personal protection
Control parameters:
Quartz, respirable dust, (see crystalline silica)(CAS#14808-60-7): Occupational Exposure
Limit Value (8-hour reference period): 0.1 mg/ m3 (Ireland)
Quartz, total(CAS#14808-60-7): 0.3 mg/ m3 (Denmark)
Quartz (CAS#14808-60-7): 0.1 mg/ m3 (Malaysia)

Appropriate engineering controls:
Handle in accordance with good industrial hygiene and safety practice. Wash hands before
breaks and at the end of workday.
Personal protective equipment:
Eye/face protection:
Wear chemical splash goggles.
Skin protection:
Wear appropriate protective clothing to prevent skin exposure.
Respiratory protection:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European
Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if
exposure limits are exceeded or if irritation or other symptoms are experienced.
Hand protection:
Wear appropriate protective gloves to prevent skin exposure.
