First Aid Measures

Ingestion

If swallowed, wash out mouth with water provided person is conscious. Call a physician.

Ingestion

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

See Inhalation.

Inhalation

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

Inhalation

If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.

Inhalation

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.

Skin

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

Skin

Get medical aid. 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.

Eyes

See Inhalation.

Eyes

Assure adequate flushing of the eyes by separating the eyelids with fingers.

Eyes

Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Exposure Controls/Personal Protection

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 government approved respirator, chemical-resistant gloves, safety goggles, other protective clothing. Faceshield (8-inch minimum).

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

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.

Exposure Effects

Corrosive. Causes burns. Harmful by inhalation, in contact with skin and if swallowed.

Fire Fighting Measures

Flash Point

192

Fire Fighting

Extinguish using Dry chemical powder. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

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 water spray, dry chemical, carbon dioxide, 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 Measures

Small spills/leaks

Clean up spills immediately, using the appropriate protective equipment. Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Provide ventilation.

Small spills/leaks

Cover with dry lime or soda ash, pick up, keep in a closed container, and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete.

Stability and Reactivity

Incompatibilities

Acids.

Incompatibilities

Oxidizing agents.

Stability

Stable under normal temperatures and pressures.

Decomposition

Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.

Decomposition

Hydrogen bromide gas.

Combustion Products

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