SECTION 3- HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
APPEARANCE: white solid. DANGER! Causes eye and skin burns. Corrosive. Hygroscopic.
Harmful if swallowed. May cause severe respiratory tract irritation with possible burns. May cause
severe digestive tract irritation with possible burns. May cause skeletal abnormalties.
TARGET ORGANS: Kidneys, respiratory system, skeletal structures.
POTENTIAL HEALTH EFFECTS
EYE: Causes e

y
e burns. Ma

y
cause chemical con

j
uctivitis and corneal dama

g
e.
SKIN: Contact with liquid is corrosive and causes sever burns and ulceration. May penetrate the
skin and cause sever tissue and bone destruction. May cause skin rash (in milder
cases), and cold and clammy skin with cyanosis and pale color.
INGESTION: Harmful if swallowed. May cause severe and permanent damage to the digestive tract.
May cause kidney damage. May cause perforation of the digestive tract. Causes
severe digestive tract burns with abdominal pain, vomiting, and possible death.
Inorganic fluorides can be harmful. Acute exposure to fluorine compounds can lead to
digestive tract burns, and abdominal pain. Fluorides can reduce calcium levels
leading to fatal hypocalcemia. May cause systemic effects.
INHALATION: Causes chemical burns to the respiratory tract. Inhalation may be fatal as a result of

spasm, inflammation, edema of the larnyx and bronchi, chemical pneumonitis and
pulmonary edema. Aspiration may lead to pulmonary edema. Depletes calcium levels
in the body which can lead to hypocalcemia and death. 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 digestive tract disturbances. Effects may be delayed. Chronic exposure to fluoride
may cause systemic toxicity.

SECTION 4 – FIRST AID MEASURES
EYES: Get medical aid immediately. Do NOT allow victim to rub 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 soap and water for at
least 15 minutes while removing contaminated clothing nd shoes. Wash clothing before
reuse. Destsroy 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 to fresh air immediately. If not
breathing, give artificial respiration. 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 or mask.
NOTES TO PHYSICIAN: Treat symptomatically and supportively.

SECTION 5 – FIRE FIGHTING MEASURES
GENERAL INFORMATION: As in any fire, wear 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. Use water spray to keep fire-exposed containers cool. Wear appropriate
(SCBA) to prevent contact with thermal decomposition products. Contact with metals
may evolve flammable hydrogen gas. Contatiners may explode when heated. Non-
combustible, substance itself does not burn but may decompose upon heating to
produce corrosive and/or toxic fumes.
EXTINGUISHING NOTES: Use water spray to cool fire-exposed containers. Substance is non-
combustible; use agent most appropriate to extinguish surrounding fire. Do NOT get
water inside containers. For small fires, use dry chemical, carbon dioxide or water
spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or
water spray.

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 runoff into storm sewers and ditches which lead to waterways. Clean up spills
immediately, observing precautions in the Protective Equipment section. Avoid gen-
erating dusty conditions. Provide ventilation.

SECTION 7- HANDLING AND STORAGE
HANDLING: Wash thoroughly after handling. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Do not breathe dust, vapor, mist, or gas. Do not get
in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or
inhale. Use only in a chemical fume hood. Discard contaminated shoes.
STORAGE: Keep away form heat and flame. Keep conatiner closed when not in use. Store in a
tightly closed conatiner. Corrosive area. Keep away form acids. Keep away from
bases. Store protected.
