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

EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed.

Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns.
Skin:
May cause deep, penetrating ulcers of the skin. May cause severe
irritation and possible burns.
Ingestion:
May cause vascular collapse and damage. Causes severe digestive
tract burns with abdominal pain, vomiting, and possible death. May
cause hemorrhaging of the digestive tract.
Inhalation:
Causes delayed lung injury. May cause severe respiratory tract
irritation.
Chronic:
Chronic inhalation and ingestion may cause chronic fluoride
poisoning (fluorosis) characterized by weight loss, weakness,
anemia, brittle bones, and stiff joints.

**** 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 immediately. 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.
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 not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Notes to Physician:

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

General Information:
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:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.

**** 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.

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

Handling:
Wash thoroughly after handling. Use with adequate ventilation. Do
not get on skin or in eyes. Do not ingest or inhale.
Storage:
Store in a tightly closed container. Keep from contact with
oxidizing materials. Store in a cool, dry, well-ventilated area away
from incompatible substances. Keep away from water. Keep away from
acids. Keep away from strong bases.

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

Engineering Controls:
Local exhaust ventilation may be necessary to control any air
contaminants to within their TLVs during the use of this product.
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.
