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.

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.

Fire Fighting Measures

Flash Point

70

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.

Fire Potential

Non-Combustible

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. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Stability

Stable under normal temperatures and pressures.

Incompatibilities

Strong oxidizing agents.

Decomposition

Hydrogen chloride, carbon monoxide, oxides of nitrogen, irritating and toxic fumes and gases, carbon dioxide, hydrogen fluoride.

Combustion Products

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
