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

EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin. May cause
sensitization by inhalation and skin contact.

Potential Health Effects
Eye:
May cause severe eye irritation.
Skin:
Causes skin irritation. May cause hives. May cause dermatitis.
Ingestion:
May cause irritation of the digestive tract.
Inhalation:
Dust is irritating to the respiratory tract. May cause allergic
respiratory reaction. May cause asthmatic attacks due to allergic
sensitization of the respiratory tract.
Chronic:
Chronic inhalation may cause effects similar to those of acute
inhalation.

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

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid. Flush skin with plenty of soap and water for at
least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
Call a poison control center. If swallowed, do not induce vomiting
unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. 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.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
Dusts at sufficient concentrations can form explosive mixtures with
air. Wear appropriate protective clothing to prevent contact with
skin and eyes. Wear a self-contained breathing apparatus (SCBA) to
prevent contact with thermal decomposition products.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For small fires, 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. Provide ventilation.

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

Handling:
Use with adequate ventilation. Minimize dust generation and
accumulation. Avoid contact with skin and eyes. Avoid ingestion and
inhalation.
Storage:
Keep from contact with oxidizing materials. Store in a cool, dry,
well-ventilated area away from incompatible substances.

**** 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
ventilation to keep airborne concentrations low.
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 gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
