**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable.Moisture sensitive.
Potential Health Effects
Eye:
May cause eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
May cause irritation and dermatitis. May cause cyanosis of the
extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause cardiac disturbances. Ingestion of large amounts
may cause CNS depression.
Inhalation:
May cause respiratory tract irritation. Aspiration may lead to
pulmonary edema. Vapors may cause dizziness or suffocation. May cause
cardiac abnormalities. May cause burning sensation in the chest.
Chronic:
Effects may be delayed.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing
is difficult, give oxygen. Get medical aid. 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:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Will burn if involved in a fire. Use
water spray to keep fire-exposed containers cool. Containers may
explode in the heat of a fire. Flammable liquid and vapor. Vapors
may be heavier than air. They can spread along the ground and
collect in low or confined areas. Runoff from fire control or
dilution water may cause pollution. Runoff to sewer may create fire
or explosion hazard.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Water may be
ineffective. Do NOT get water inside containers. Do NOT use straight
streams of water. For large fires, use water spray, fog or regular
foam. For small fires, use dry chemical, carbon dioxide, water spray
or regular 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. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. Do
not get water inside containers. A vapor suppressing foam may be
used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Avoid breathing dust, vapor, mist, or gas. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. Keep container
tightly closed. Keep away from heat, sparks and flame. Avoid
ingestion and inhalation. Do not allow contact with water. Use only
in a chemical fume hood. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames. Keep from contact with moist air and steam.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Keep under a nitrogen blanket. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area. Store protected from moisture.
**** 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.

respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
