Special protective equipment and precautions for fire fighters
As in any fire, wear a self?contained breathing apparatus in pressure?demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Special Hazards: Carbon, nitrogen, sulphur & sodium oxides.
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
No further information available.
Environmental precautions
Methods and materials for containment and clean up
Clean up spills immediately, observing precautions in the Protective Equipment Section. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation.
7. HANDLING AND STORAGE
Precautions for safe handling
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with skin and eyes. Keep container tightly closed. Do not ingest or inhale.
Conditions for safe storage
Store in a cool, dry, well?ventilated area away from incompatible substances. Keep containers tightly closed.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Standards
Engineering controls
Use adequate ventilation to keep airborne concentrations low.
Personal protective equipment
Eye and face protection
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin protection
Wear appropriate protective gloves to prevent skin exposure. 0.11mm thick nitrile.
Body protection
Wear appropriate protective clothing to prevent skin exposure.
Respiratory protection
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirators use.
