**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation, in contact with skin and if
swallowed. Causes severe burns.

Potential Health Effects
Eye:
Causes eye burns. Vapors may cause eye irritation.
Skin:
Causes skin burns. May be absorbed through the skin in harmful
amounts. Prolonged or repeated contact may dry/defat the skin and
cause irritation.
Ingestion:
Causes gastrointestinal tract burns. May be harmful if swallowed.
Inhalation:
Inhalation may produce coughing, nausea, and pulmonary edema.
Chronic:
Chronic exposure may cause effects similar to those of acute
exposure.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
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:

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

General Information:
Use water spray to keep fire-exposed containers cool. 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. Extremely flammable
liquid and vapor. Vapor may cause flash fire. Vapors are heavier than
air and may travel to a source of ignition and flash back. Vapors can
spread along the ground and collect in low or confined areas.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. 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. Use water spray to dilute spill to
a non-flammable mixture. Use water spray to disperse the gas/vapor.
Remove all sources of ignition. Provide ventilation. Approach spill
from upwind.

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

Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Do not get in eyes,
on skin, or on clothing. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Avoid ingestion and
inhalation. Do not pressurize, cut, weld, braze, solder, drill,
grind, or expose empty containers to heat, sparks or open flames. Use
only with adequate ventilation. Keep away from heat, sparks and
flame.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Keep from contact
with oxidizing materials. Store in a cool, dry, well-ventilated area
away from incompatible substances. Keep away from organic halogens.
Keep away from acids.

**** 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
