**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic if swallowed. Contact with acids liberates very toxic gas.
Irritating to eyes and skin.Moisture sensitive.
Potential Health Effects
Eye:
Causes eye irritation and possible burns. May cause chemical
conjunctivitis and corneal damage.
Skin:
Contact with skin causes irritation and possible burns, especially
if the skin is wet or moist. May cause skin rash (in milder cases),
and cold and clammy skin with cyanosis or pale color.
Ingestion:
Ingestion of large amounts of fluoride may cause salivation, nausea,
vomiting, abdominal pain, fever, labored breathing. Exposure to
fluoride compounds can result in systemic toxic effects on the heart,
liver, and kidneys. It may also deplete calcium levels in the body
leading to hypocalcemia and death. May cause irritation of the
digestive tract and possible burns. May cause respiratory paralysis
and cardiac arrest.
Inhalation:
May cause severe irritation of the respiratory tract with possible
burns. Aspiration may lead to pulmonary edema. Prolonged exposure to
dusts, vapors, or mists may result in the perforation of the nasal
septum. May cause systemic effects.
Chronic:
Chronic inhalation and ingestion may cause chronic fluoride
poisoning (fluorosis) characterized by weight loss, weakness,
anemia, brittle bones, and stiff joints. May cause reproductive and
fetal effects. Effects may be delayed. Chronic exposure may cause
lung damage. Laboratory experiments have resulted in mutagenic
effects. Chronic exposure to fluoride compounds may cause systemic
toxicity. Skeletal effects may include bone brittleness, joint
stiffness, teeth discoloration, tendon calcification, and
osterosclerosis. Animal studies have reported the development of
tumors.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
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 breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
Notes to Physician:
Individuals who suffer from diabetes insipidus or some form of renal
impairment may be at increased risk from the effects of fluoride. Due
to delayed and persistent symptoms, observe patient closely for 48
hours. Treat symptomatically and supportively.
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. Material will not burn. During a fire, irritating
and highly toxic gases may be generated by thermal decomposition or
combustion.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Do NOT get water inside containers. Use water spray, dry chemical,
carbon dioxide, or appropriate 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. Do not flush into a sewer. 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:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Do not ingest or inhale. Do
not allow contact with water. Discard contaminated shoes. Keep from
contact with moist air and steam.
Storage:
Keep container closed when not in use. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Keep away from strong acids. Store protected
from moisture. Store away from alkalies.
**** 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.
