**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. May
cause sensitization by skin contact. Very toxic to aquatic
organisms, may cause long-term adverse effects in the aquatic
environment.Air sensitive.Light sensitive.
Potential Health Effects
Eye:
Causes eye irritation. May cause conjunctivitis and keratitis.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts. May cause skin sensitization, an allergic reaction, which
becomes evident upon re-exposure to this material. May produce
eczematoid contact dermatitis.
Ingestion:
Harmful if swallowed. May cause irritation of the digestive tract.
May cause liver and kidney damage. Ingestion may cause gastritis,
vertigo, tremors, convulsions, and possible coma.
Inhalation:
Dust is irritating to the respiratory tract. May cause asthmatic
attacks due to allergic sensitization of the respiratory tract. May
cause rhinitis (inflammation of the mucous membrane of the nose).
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Prolonged
or repeated exposure may cause adverse reproductive effects.
**** 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:
Flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists.
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:
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.
Notes to Physician:
Antidote:
None reported.
**** 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.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid generating dusty conditions. Remove all sources of
ignition.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Minimize dust generation and accumulation. Avoid contact with skin
and eyes. Keep away from heat, sparks and flame. Do not ingest or
inhale.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Material
darkens on exposure to air.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels.
