**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Highly flammable. Toxic by inhalation and in contact with skin.
Causes burns.

Potential Health Effects
Eye:
Contact with liquid or vapor causes severe burns and possible
irreversible eye damage. Contact may cause ulceration of the
conjunctiva and cornea. Eye damage may be delayed. May cause
conjunctivitis. May cause blindness.
Skin:
Harmful if absorbed through the skin. May be absorbed through the
skin. If absorbed, causes symptoms similar to those of ingestion.
Penetration may continue for several days. Causes severe skin
irritation and burns.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns. Can cause
nervous system damage. May cause tremors and convulsions.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema. Causes
chemical burns to the respiratory tract. May cause effects similar
to those described for ingestion. Damage may be delayed. May cause
bronchial pneumonia.
Chronic:
Repeated inhalation may cause chronic bronchitis. Prolonged or
repeated contact may cause skin necrosis and/or ulceration of the
skin. May cause chronic cough.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Gently lift eyelids and flush continuously with water.
Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Discard contaminated clothing in a manner which limits further
exposure. Destroy contaminated shoes.
Ingestion:
Do not induce vomiting. 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:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do not use
mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
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. 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. Vapor may explode if ignited in a confined
area. 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. Do NOT get water inside containers. 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:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Cover with sand, dry lime or soda ash and place in
a closed container for disposal. Remove all sources of ignition.
Provide ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Ground and bond
containers when transferring material. Do not get in eyes, on skin,
or on clothing. Empty containers retain product residue, (liquid
and/or vapor), and can be dangerous. Do not ingest or inhale. Use
only in a chemical fume hood. Discard contaminated shoes. 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. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from strong acids. Flammables-area. Corrosives 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. Ventilation fans and
other electrical service must be non-sparking and have an
explosion-proof design.
Exposure Limits

Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves and clothing to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29
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.
