Special protective equipment and precautions for fire fighters
Carbon & Nitrogen oxides, hydrogen chloride gas. 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
6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures
Use proper PPE
Environmental precautions
Clean up spills immediately, observing precautions in the Protective Equipment Section.
Methods and materials for containment and clean up
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Provide ventilation.
