Inhalation:
Remove from exposure and move to fresh air immediately. 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. Flammable liquid and vapor.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use foam, dry
chemical, or carbon dioxide. Water may be ineffective.

**** 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.

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

Handling:
Use spark-proof tools and explosion proof equipment. Avoid breathing
dust, vapor, mist, or gas. Avoid contact with skin and eyes. Use and
store under nitrogen.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Flammables-area. Store under
nitrogen.

**** 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.
Exposure Limits
CAS# 96-17-3:

Personal Protective Equipment
