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

EMERGENCY OVERVIEW
Highly flammable. Reacts violently with water liberating extremely
flammable gases. Spontaneously flammable in air. Causes burns.
Harmful : danger of serious damage to health by prolonged exposure
through inhalation. Possible risk of impaired fertility. Toxic to
aquatic organisms, may cause long-term adverse effects in the aquatic
environment. Harmful: may cause lung damage if swallowed. Vapours may
cause drowsiness and dizziness.Water-reactive.Corrosive.

Potential Health Effects
Eye:
Causes severe eye burns. May cause irreversible eye injury.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration.
Ingestion:
Aspiration hazard. May cause central nervous system depression,
kidney damage, and liver damage. Causes digestive tract burns with
immediate pain, swelling of the throat, convulsions, and possible
coma. Aspiration of material into the lungs may cause chemical
pneumonitis, which may be fatal.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Irritation may lead to chemical pneumonitis and pulmonary
edema. Causes severe irritation of upper respiratory tract with
coughing, burns, breathing difficulty, and possible coma. May cause
effects similar to those described for ingestion.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion. Chronic exposure may cause kidney
damage.

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

Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Possible aspiration hazard. Get medical aid
immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
Notes to Physician:

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

General Information:
Evacuate area and fight fire from a safe distance. Containers can
build up pressure if exposed to heat and/or fire. 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. Combustion
generates toxic fumes. Material is easily ignited if allowed to dry.
Extremely flammable. Material will readily ignite at room
temperature. Water Reactive. Material will react with water and may
release a flammable and/or toxic gas. Use water spray to keep
fire-exposed containers cool. Water may be ineffective. Material is
lighter than water and a fire may be spread by the use of water. Can
form explosive mixtures at temperatures above the flashpoint. Vapors
may be heavier than air. They can spread along the ground and
collect in low or confined areas.
Extinguishing Media:
Water may be ineffective. Do NOT use carbon dioxide. DO NOT USE
WATER! Use dry chemical. Do NOT use straight streams of water. Cool
containers with flooding quantities of water until well after fire
is out.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Scoop up with a nonsparking tool, then place into
a suitable container for disposal. Remove all sources of ignition.
Absorb spill using an absorbent, non-combustible material such as
earth, sand, or vermiculite. Do not use combustible materials such as
sawdust. Provide ventilation.

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

Handling:
Remove contaminated clothing and wash before reuse. Ground and bond
containers when transferring material. Do not get in eyes, on skin,
or on clothing. Empty containers retain product residue, (liquid
and/or vapor), and can be dangerous. Keep container tightly closed.
Do not ingest or inhale. Do not allow contact with water. Use only in
a chemical fume hood. Store and handle protected from air. Do not use
if the material has evaporated to dryness. Do not pressurize, cut,
weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Keep container closed to prevent drying out. Keep under a
nitrogen blanket. Keep from contact with oxidizing materials. Store
in a cool, dry, well-ventilated area away from incompatible
substances. Keep away from water. Keep away from organic halogens.
Refrigerator/flammables.

**** 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 explosion-proof ventilation to keep airborne levels to
acceptable levels.
