**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if
swallowed.Hygroscopic.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
May cause skin irritation.
Ingestion:
Harmful if swallowed. Ingestion of large amounts of fluoride may
include salivation, nausea, vomiting, abdominal pain, fever, labored
breathing. Inorganic fluorides can be harmful. Acute exposure to
fluorine compounds can lead to digestive tract burns, and abdominal
pain. 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. Causes
gastrointestinal tract irritation. Contains fluoride. Fluoride can
reduce calcium levels leading to fatal hypocalcemia.
Inhalation:
May cause 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. Chronic exposure to
fluoride compounds may cause systemic toxicity.
**** 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:
Get medical aid immediately. Flush skin with plenty of soap and
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse.
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 to fresh air
immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or alcohol-resistant
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. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Use only
in a well-ventilated area. Minimize dust generation and accumulation.
Avoid contact with eyes, skin, and clothing. Avoid ingestion and
inhalation. Wash clothing before reuse.
Storage:
Store in a cool, dry, well-ventilated area away from incompatible
substances. Keep containers tightly closed.
**** 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 protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.
