EMERGENCY OVERVIEW
Moisture sensitive.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
May cause respiratory tract irritation.
Chronic:
Not available.
**** 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.
Skin:
Flush skin with plenty of soap and water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Wash clothing before reuse.
Ingestion:
Do NOT induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid.
Inhalation:
Remove from exposure to fresh air immediately. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid if cough or other symptoms appear.
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. Dusts at sufficient concentrations can form
explosive mixtures with air. Dousing metallic fires with water may
generate hydrogen gas, an extremely dangerous explosion hazard.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam. Do
NOT get water inside containers.
**** 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. Very fine particles can cause a fire or explosion.
Eliminate all ignition sources. Clean up spills immediately,
observing precautions in the Protective Equipment section. Avoid
generating dusty conditions. Provide ventilation. Do not get water
inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Minimize dust generation and accumulation. Avoid contact with skin
and eyes. Avoid ingestion and inhalation. Do not allow contact with
water. Use only in a chemical fume hood. Keep from contact with moist
air and steam.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from moisture.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Good general ventilation should be sufficient to control airborne
levels. Facilities storing or utilizing this material should be
equipped with an eyewash facility and a safety shower.
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 to prevent skin
exposure.
Clothing:
Wear a chemical apron. Wear appropriate protective
clothing to prevent skin exposure.
Respirators:
A NIOSH/MSHA approved air purifying dust or mist
respirator or European Standard EN 149.
