Hazards and Protection.
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.
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. Avoid contact with 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 vapors.
Protection
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 a respirator's use.
Small spills/leaks
Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Use a spark-proof tool. Provide ventilation.
Disposal code

Stability
Stable under normal temperatures and pressures.
Incompatibilities
Moisture, explosive reaction with cyanogen fluoride; glycerol + nitric acid; sodium (with aqueous acid); methanesulfonic acid (evolves oxygen difluoride that explodes). Violent reaction with As2O3; P2O5; acetic anhydride; NH4OH; HBiO3; CaO; F2; potassium permanganate; Na; NaOH; H2SO4; vinyl acetate; HgO; Dangerous storage hazard with nitric acid + lactic acid; nitric acid + propylene glycol (mixtures evolve gas which may burst a sealed container). Reacts with water or steam to produce toxic and corrosive fumes. Strong oxidants. Dinitrogen tetroxide, maleic anhydride, N2O4, Chlorine, Hypochlorite, and halogenated compounds. Strong bases, glass, metals, Alkali metals, light.
Decomposition
Nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen fluoride, nitrogen, fluoride fumes.

Fire.
Fire fighting
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. 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.
Fire potential
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Hazards
Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases. Reaction with water may generate much heat which will increase the concentration of fumes in the air. Contact with metals may evolve flammable hydrogen gas.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
Effects may be delayed. Chronic effects of exposure include weight loss, malaise, anemia, bloo d effects, discoloration of the teeth, and osteosclerosis.
   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. Inhalation at high concentrations may cause CNS depression and asphixiation.
   Skin
May be fatal if absorbed through the skin. Causes severe burns with delayed tissue destruction. May cause cyanosis of the extremities.
   Eyes
Causes severe eye burns. May cause ulceration of the the cornea with loss of vision

First aid
 
   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 to fresh air immediately. If breathing is difficult, give oxygen. SPEED IS ESSENTIAL, OBTAIN MEDICAL AID IMMEDIATELY. Do not use mouth-to-mouth respiration 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.
   Skin
Wash clothing before reuse. Destroy contaminated shoes. SPEEDY ACTION IS CRITICAL, GET MEDICAL AID IMMEDIATELY. Spills of HF should be flushed for a MAXIMUM of 5 minutes.
   Eyes
Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Spills of HF should be flushed for a MAXIMUM of 5 minutes.
