**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Irritating to eyes, respiratory system and skin.
Potential Health Effects
Eye:
Causes eye irritation. Causes redness and pain. May cause
chemical conjunctivitis and corneal damage.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
defatting of the skin and dermatitis. Causes redness and pain. 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:
Effects may be delayed. Causes respiratory tract irritation. May
cause dizziness, incoordination, and unconsciousness. Aspiration may
lead to pulmonary edema. Vapors may cause dizziness or suffocation.
Can produce delayed pulmonary edema. May cause burning sensation in
the chest.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis. May cause liver and kidney damage. Prolonged exposure may
produce a narcotic effect. 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. Wash mouth out with 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. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Treat symptomatically and supportively.
**** 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. Use water spray to keep fire-exposed
containers cool. Water may be ineffective. Material is lighter than
water and a fire may be spread by the use of water. 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. May polymerize explosively when
involved in a fire. Runoff to sewer may create fire or explosion
hazard.
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. Cool containers with flooding quantities of water until well
after fire is out.
**** 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. A
vapor suppressing foam may be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Avoid contact with
eyes, skin, and clothing. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Take precautionary
measures against static discharges. Keep container tightly closed.
Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Use with adequate ventilation. Wash clothing before
reuse. This product may be under pressure; cool before opening. Do
not use if the material has evaporated to dryness. 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. Do not store in direct sunlight. Store in a tightly closed
container. 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 explosion-proof ventilation to keep airborne levels to
acceptable levels.
