**** 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. May result in corneal injury.
Skin:
May be absorbed through the skin in harmful amounts. Prolonged
and/or repeated contact may cause irritation and/or dermatitis.
Ingestion:
May cause irritation of the digestive tract. May cause central
nervous system depression, characterized by excitement, followed by
headache, dizziness, drowsiness, and nausea. Advanced stages may
cause collapse, unconsciousness, coma and possible death due to
respiratory failure.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation. Irritation may lead to
chemical pneumonitis and pulmonary edema. May cause numbness in the
extremities.
Chronic:
Chronic inhalation may cause effects similar to those of acute
inhalation. Prolonged or repeated skin contact may cause defatting
and dermatitis. Animal studies have reported that fetal
effects/abnormalities may occur when maternal toxicity is seen.
**** 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. Do NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid. Rinse area with large amounts of water for at least
15 minutes. Remove contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid immediately.
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. Do NOT use mouth-to-mouth
resuscitation. If breathing has ceased apply artificial respiration
using oxygen and a suitable mechanical device such as a bag and a
mask.
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 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. Flammable Liquid.
Can release vapors that form explosive mixtures at temperatures above
the flashpoint. 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. 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. 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. 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.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use only in a well-ventilated area. 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. Keep away from
heat, sparks and flame. Avoid ingestion and inhalation. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. 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.
