Section 3 - HAZARDS IDENTIFICATION
  EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Causes severe burns.Hygroscopic (absorbs moisture from the air).Corrosive.
Potential Health Effects
Eye:
Causes severe eye burns. May cause ulceration of the the cornea with loss of vision Skin:
May be fatal if absorbed through the skin. Causes severe burns with delayed tissue destruction. May cause cyanosis of the extremities.
Ingestion:
May be fatal if swallowed. May cause liver and kidney damage. Causes severe digestive tract burns with abdominal pain, vomiting, and possible death. May cause effects similar to those for inhalation exposure. May cause systemic effects.
Inhalation:
May be fatal if inhaled. Causes delayed lung injury. Inhalation of high vapor concentrations may cause ulceration of nasal mucous and possibly bronchospasm. Aspiration may lead to pulmonary edema. May cause coughing, choking, chills, fever, tightness in the chest, and cyanosis (bluish discoloration of skin due to deficient oxygenation of the blood). Inhalation at high concentrations may cause CNS depression and asphixiation.
Chronic:
Effects may be delayed.

Section 4 - FIRST AID MEASURES
  Eyes: Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed. Spills of HF should be flushed until medical attention arrives. SPEEDY ACTION IS CRITICAL! GET MEDICAL ATTENTION IMMEDIATELY! Skin:
Wash clothing before reuse. Destroy contaminated shoes. SPEEDY ACTION IS CRITICAL, GET MEDICAL AID IMMEDIATELY. Spills of HF should be flushed until medical attention arrives. SPEEDY ACTION IS CRITICAL! GET MEDICAL ATTENTION IMMEDIATELY.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical aid immediately. SPEED IS ESSENTIAL. A DOCTOR MUST BE NOTIFIED AT ONCE. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. SPEED IS ESSENTIAL, OBTAIN MEDICAL AID IMMEDIATELY. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Notes to Physician:
Antidote: Skin or eye exposure should be treated with 25% Calcium gluconate gel until burning ceases. May be necessary to administer subcutaneously. Ingestion may be treated with milk, chewable Calcium carbonate tablets or Milk of Magnesia.

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. Use water spray to keep fire-exposed containers cool. Combustible liquid.
Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Containers may explode when heated.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. In case of fire, use carbon dioxide, dry chemical powder or appropriate foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective Equipment section. Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Do not use combustible materials such as sawdust. Use a spark-proof tool. Provide ventilation.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Do not ingest or inhale. Use only in a chemical fume hood. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Do not breathe vapor.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area. Do not store in metal or glass containers. Store protected from moisture.

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 general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
Exposure Limits CAS# 73602-61-6: United States OSHA: 2.5 mg/m3 TWA (as F) (listed under Fluorides 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:
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use.
