solvents.
Avoid storing product near incompatible materials. See MSDS Section 10.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Local exhaust ventilation as necessary to maintain exposures to within applicable
Engineering Controls:
limits. Please refer to the ACGIH document, "Industrial Ventilation, A Manual of
Recommended Practices", most recent edition, for details.
When exposures exceed the PEL or TLV, use NIOSH/MSHA approved respirator
Respiratory Protection:
in accordance with OSHA Respiratory Protection Requirements under 29 CFR
1910.134.
Appropriate chemical resistant gloves should be worn.
Gloves:
Wear chemically protected gloves (neoprene or rubber), boots, aprons, and
