**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Irritating to eyes. Repeated exposure may cause
skin dryness or cracking. Vapours may cause drowsiness and
dizziness.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Repeated or prolonged exposure may cause drying and cracking of the
skin. A single prolonged skin exposure is not likely to result in
the material being absorbed in harmful amounts.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation. May cause narcotic
effects in high concentration. Exposure may produce optic nerve
damage and possible blindness. Overexposure may lead to convulsions,
shortness of breath, and stupor.
Chronic:
Chronic inhalation may cause effects similar to those of acute
inhalation.
**** 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 if irritation develops or persists. Flush skin with
plenty of soap and water.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid.
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:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Use water spray to keep fire-exposed containers
cool. Containers may explode in the heat of a fire. 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:
Use water spray to cool fire-exposed containers. Use foam, dry
chemical, or carbon dioxide. 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. Remove all sources of ignition.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. 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. Avoid breathing vapor or mist.
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. Flammables-area.
**** 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.
