Notes to Physician:

**** 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. Wear appropriate protective clothing to prevent contact with
skin and eyes. Wear a self-contained breathing apparatus (SCBA) to
prevent contact with thermal decomposition products. Flammable liquid
and vapor.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.

**** 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. Use water spray to dilute spill to
a non-flammable mixture. Remove all sources of ignition.

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

Handling:
Use only in a well-ventilated area. Avoid contact with eyes, skin,
and clothing. Keep away from heat, sparks and flame. Avoid ingestion
and inhalation.
Storage:
Keep away from heat, sparks, and flame. Keep refrigerated. (Store
below 4C/39F.) Store in a tightly closed container. Store in a dry
area. Flammables-area.

**** 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
