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. Vapors or dust may form explosive mixture with air. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Fire potential
This chemical is combustible.
Hazards
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
May cause liver and kidney damage. Absorption into the body leads to the formation of methemoglobin which in sufficient concentrations causes cyanosis.
   Ingestion
May cause irritation of the digestive tract. Poison by ingestion. May cause nausea and vomiting.
   Inhalation
May cause respiratory tract irritation. Toxic if inhaled. May cause nausea, dizziness, and headache.
   Skin
May cause skin irritation. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Absorption into the body may cause cyanosis. Causes redness and pain. Toxic in contact with skin.
   Eyes
May cause eye irritation. Eye damage may be delayed. Causes redness and pain.

First aid
 
   Ingestion
Get medical aid immediately. Wash mouth out with water.
   Inhalation
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
   Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
