**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. The toxicological properties of this substance have not
been fully investigated.
Inhalation:
May cause respiratory tract irritation. The toxicological properties
of this substance have not been fully investigated.
Chronic:
Adverse reproductive effects have been reported in animals.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
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:
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 not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
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
may form an explosive mixture with air. May burn with invisible
flame. 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 solid.
Spontaneously ignitable in air.
Extinguishing Media:
Use dry sand or earth to smother fire. For large fires, use water
spray, fog, or alcohol-resistant foam. Use water spray to cool
fire-exposed containers. Use dry chemical to fight fire. Contact
professional fire-fighters immediately.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Remove all sources of ignition. Use a
spark-proof tool. Isolate area and deny entry. Provide ventilation.
Place under an inert atmosphere. 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:
Remove contaminated clothing and wash before reuse. Use only in a
well-ventilated area. Minimize dust generation and accumulation.
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. Handle under an inert
atmosphere. 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. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Flammables-area. Do not expose to air. Store under an inert
atmosphere.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. 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.
