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 minimize contact with skin.
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 methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis, rapid heart rate, unconsciousness and possible death.
Poison Class
4 (Substances and products that must be considered harmful)
Fire Fighting Measures
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with combustible materials may cause a fire. Containers may explode in the heat of a fire. May decompose explosively when heated or involved in a fire. May accelerate burning if involved in a fire. Extinguishing media: Cool containers with flooding quantities of water until well after fire is out. For small fires DO NOT use dry chemicals, carbon dioxide, halon or foams. USE WATER ONLY. For large fires flood fire with water from a distance.
Fire Potential
These substances will accelerate burning when involved in a fire.
Accidental Release Measures
Small spills/leaks
Flush spill area with water. Do not get water inside containers. Do not use combustible materials such as paper towels to clean up spill. Cover with dry earth, dry sand, or other non-combustible material followed with plastic sheet to minimize spreading and contact with water.
Stability and Reactivity
Incompatibilities
Aluminum, ammonium nitrate.
Stability
Stable at room temperature in closed containers under normal storage and handling conditions.
Decomposition
Carbon monoxide, oxides of nitrogen, irritating and toxic fumes and gases, carbon dioxide.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
