**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed. May cause central nervous
system effects.
Inhalation:
May cause respiratory tract irritation. May cause adverse central
nervous system effects including headache, convulsions, and possible
death. Vapors may cause dizziness or suffocation.
Chronic:
Chronic ingestion may cause neurological symptoms.
**** 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
immediately.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
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 immediately.
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. Vapors may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Will burn
if involved in a fire. Use water spray to keep fire-exposed
containers cool. Extremely flammable liquid and vapor. Will be
easily ignited by heat, sparks or flame. Containers may explode when
heated.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT use straight streams of
water.
**** 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. A vapor suppressing foam may be used to reduce
vapors. Water spray may reduce vapor but may not prevent ignition in
closed spaces.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Use with
adequate ventilation. Ground and bond containers when transferring
material. 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.
This product may be under pressure; cool before opening. 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 cool, dry place. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.

CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
