Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.
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. Vapors can
travel to a source of ignition and flash back. Will burn if involved in a fire. Containers may
explode in the heat of a fire. Flammable liquid and vapor. May form explosive peroxides. Forms
explosive mixtures with air.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam.

Upper: Not available.
NFPA Rating: (estimated) Health: 2; Flammability: 3; Instability: 0
Section 6 - Accidental Release Measures
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in
suitable container. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.
Section 7 - Handling and Storage
Handling: Ground and bond containers when transferring material. Use spark-proof tools and
explosion proof equipment. Avoid contact with eyes, skin, and clothing. Do not breathe vapor.
Use only with adequate ventilation. Keep away from heat, sparks and flame.
Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Flammables-area. Storage under a nitrogen blanket has been
recommended.
Section 8 - Exposure Controls, Personal Protection
Engineering Controls: Facilities storing or utilizing this material should be equipped with an
eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations
low.
