**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
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. Containers
may explode in the heat of a fire.
Extinguishing Media:
Use agent most appropriate to extinguish fire. Cool containers with
flooding quantities of water until well after fire is out.

closed container for disposal. Avoid generating dusty conditions. A
vapor suppressing foam may be used to reduce vapors.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Avoid
ingestion and inhalation.
Storage:
Store in a cool, dry place. Keep container closed when not in use.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
