**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable.Air sensitive.Moisture sensitive.
Potential Health Effects
Eye:
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. Ingestion of large amounts may cause CNS depression.
Inhalation:
Aspiration may lead to pulmonary edema. Vapors may cause dizziness
or suffocation. May cause burning sensation in the chest.
Chronic:
Not available.
**** 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
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
Ingestion:
Get medical aid immediately. Do NOT induce vomiting. If conscious
and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
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.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
Evacuate area and fight fire from a safe distance. 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. May burn with
invisible flame. 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. Spontaneously ignitable in
air. Vapors may be heavier than air. They can spread along the
ground and collect in low or confined areas.
Extinguishing Media:
Do NOT use water directly on fire. Use water spray to cool
fire-exposed containers. Do NOT get water inside containers. Contact
professional fire-fighters immediately. In case of fire, use carbon
dioxide, dry chemical powder or appropriate foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
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. Use a spark-proof tool.
Place under an inert atmosphere. Do not get water inside containers.
Do not use combustible materials such as paper towels to clean up
spill. A vapor suppressing foam may be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Ground and
bond containers when transferring material. Use spark-proof tools and
explosion proof equipment. Avoid contact with skin and eyes. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Use and store under nitrogen. Do not allow contact with
water. Store and handle protected from air. 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. Do not breathe vapor.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Flammables-area. Keep containers tightly closed. Do not
expose to air. Store protected from moisture. Store under an inert
atmosphere. Store in a cool, dry area away from incompatible
substances.
**** 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.
