| SECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION |
|-------------------------------------------------------------------------|
ENGINEERING CONTROLS: If dry-sanding, provide sufficient mechanical
ventilation to maintain exposure below PEL and TLV. While mixing, provide
sufficient mechanical ventilation (local or general exhaust) to maintain
exposure below PEL and TLV.
RESPIRATORY PROTECTION: National Institute for Occupational Safety and
Health (NIOSH) has recommended that the permissible exposure limit be
changed to 50 micrograms respirable free silica per cubic meter of air
(0.05 mg/m3) as determined by a full shift sample up to 10 hour working
day, 40 hours per week. The 1974 NIOSH Criteria for a recommended Standard
for Occupational Exposure to Crystalline Silica should Be consulted for
more detailed information. If 8 hour exposure limit or value is exceeded
for any component, use an approved NIOSH/OSHA dust mask. Consult your
safety equipment supplier and the OSHA regulation, 29 CFR 1910.134 for
respirator requirements. A respiratory protection program that meets OSHA
1910.134 and ANSI Z88.2 requirements must be followed whenever workplace
conditions warrant a respirator's use.
