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
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
Absorption into the body leads to the formation of methemoglobin which in sufficient concentrations causes cyanosis. Onset may be delayed 2 to 4 hours or longer.

Fire Fighting Measures

Flash Point
80
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will burn if involved in a fire. Combustible Liquid. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container.

Stability and Reactivity

Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong acids - strong bases - strong oxidizing agents - strong reducing agents.
Decomposition
Nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen fluoride.
