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

EMERGENCY OVERVIEW
Highly flammable. Toxic by inhalation and if swallowed. Causes
burns.Corrosive.Flammable liquid.

Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns.
Ingestion:
May be fatal or cause blindness if swallowed. Poison by ingestion.
Causes gastrointestinal tract burns. May cause liver and kidney
damage. 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. May cause cardiac
disturbances. Aspiration of material into the lungs may cause
chemical pneumonitis, which may be fatal.
Inhalation:
Harmful if inhaled. Inhalation of high concentrations may cause
central nervous system effects characterized by headache, dizziness,
unconsciousness and coma. Causes chemical burns to the respiratory
tract.
Chronic:
Chronic inhalation and ingestion may cause effects similar to those
of acute inhalation and ingestion.

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

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower lids. Get medical aid
immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
soap and water for at least 15 minutes while removing 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 to fresh air
immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
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

place into a chemical waste container.

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

Handling:
Use spark-proof tools and explosion proof equipment. Do not get on
skin and clothing. Do not breathe dust, vapor, mist, or gas. Use only
in a chemical fume hood.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Flammables-area.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
