Decomposition
Irritating and toxic fumes and gases.

Fire.
Flash Point,°C
146
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
Combustible material: may burn but does not ignite readily.
Hazards
Containers may explode when heated.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
   Ingestion
Nausea, vomiting, and diarrhea may be noted following ingestion.
   Inhalation
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Effects of contact or inhalation may be delayed.
   Skin
Cyanosis unresponsive to oxygen therapy may be noted in patients with methemoglobinemia due to absorption of excessive amounts of these agents.
   Eyes
See Skin.

First aid
 
   Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately.
   Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
