First Aid MeasuresBack to Contents
【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.
【Ingestion】

Seek medical assistance.
【Inhalation】

TOXIC; inhalation, ingestion, or skin contact with material may cause severe injury or death. Effects of contact or inhalation may be delayed.
【Inhalation】

Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method 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. Administer oxygen if breathing is difficult.
【Inhalation】

Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
【Skin】

Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
【Skin】

Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
【Skin】

Contact with molten substance may cause severe burns to skin and eyes. See Inhalation.
【Eyes】

See Inhalation.
【Eyes】

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
【Eyes】

Immediately flush with running water for at least 20 minutes.
Handling and StorageBack to Contents
【Storage】

Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Do not expose to air. Store under an inert atmosphere.
【Handling】

Wash thoroughly after handling. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Do not ingest or inhale. Handle under an inert atmosphere. Store protected from air.
Hazards IdentificationBack to Contents
【Ingestion】

See Inhalation.
【Inhalation】

May cause respiratory tract irritation. May cause a delayed damaging effect on the lung alveoli.
【Skin】

May cause skin irritation. Harmful if absorbed through the skin.
【Eyes】

Causes severe eye irritation.
【Ingestion】

Harmful if swallowed. May cause irritation of the digestive tract. Human systemic effects include acute renal failure, acute tubular necrosis, cough, diarrhea, dyspnea, headache, hypermitility, nausea, vomiting, ulceration or bleeding from stomach.
【Hazards】

Avoid strong oxidizers.
【Hazards】

Contact with metals may evolve flammable hydrogen gas.

Exposure Controls/Personal ProtectionBack to Contents
【Personal 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.
【Personal Protection】

Wear appropriate protective gloves, clothing and goggles.
【Respirators】

Wear positive pressure self-contained breathing apparatus (SCBA).
【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.
【Exposure Effects】

Effects may be delayed. Chronic ingestion may cause fetal effects. Laboratory experiments have resulted in mutagenic effects.
【Exposure limit(s)】

OSHA PEL: TWA 0.5 mg/m3 (resp) skin NIOSH REL: TWA 0.1 mg/m3 (resp) skin NIOSH IDLH: 1 mg/m3

Fire Fighting MeasuresBack to Contents
【Flash Point】

86
【Fire Fighting】

Extinguish using agent most appropriate for surrounding 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. Extinguishing media: Use agent most appropriate to extinguish fire. 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.
Accidental Release MeasuresBack to Contents
【Small spills/leaks】

Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. Place under an inert atmosphere. Cover with dry earth, dry sand, or other non-combustible material followed with plastic sheet to minimize spreading and contact with water.
【Small spills/leaks】

ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.
Stability and ReactivityBack to Contents
【Stability】

Stable under normal temperatures and pressures.
【Incompatibilities】

Strong oxidizing agents.
【Decomposition】

Hydrogen chloride, nitrogen oxides, carbon monoxide, carbon dioxide, nitrogen.
【Combustion Products】

During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
【Combustion Products】

Fire may produce irritating, corrosive and/or toxic gases.
