【EC Risk Phrase】R 36/37/38
【EC Safety Phrase】S 26 36

Exposure Controls/Personal Protection
【Personal Protection】Eyes: Wear appropriate protective eyeglasses or chemical safety ggles 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】Increases in blood pressure and pulse have been reported. An altered mental status (coma) may be seen, but is not characteristic unless hypoxemia occurs. Seizures may occur with extensive absorption. No data were available to assess the teratogenic potential of this agent.
Decreased egg production has occurred in experimental animals. Ammonia crosses the ovine placental barrier.
No data were available to assess the potential effects of exposure to this agent during lactation.
No information about possible male reproductive effects was found in available references.
【Poison Class】4

Fire Fighting Measures
【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. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.

Accidental Release Measures
【Small spills/leaks】Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity
【Stability】Stable at room temperature in closed containers under normal storage and handling conditions.
【Incompatibilities】Strong oxidizing agents.
【Decomposition】Nitrogen oxides, carbon monoxide, carbon dioxide, ammonia.
【Combustion Products】Toxic and irritating ammonia and formic acid gases may form in fire.
