Exposure Controls/Personal Protection

Personal Protection

Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

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

May cause liver and kidney damage. Absorption into the body leads to the formation of methemoglobin which in sufficient concentrations causes cyanosis.

Fire Fighting Measures

Flash Point

133

Autoignition

620

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. Containers may explode in the heat of a fire. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.

Fire Potential

May burn but will not ignite readily.

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container.

Stability and Reactivity

Incompatibilities

Oxidizing agents, acids, acid chlorides, acid anhydrides.

Stability

Stable under normal shipping and handling conditions. Substance may undergo color change upon exposure to light and air.

Decomposition

Hydrogen chloride, nitrogen oxides, carbon monoxide, carbon dioxide.

Combustion Products

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