Incompatibilities
Strong oxidizing agents, strong bases.
Decomposition
Carbon monoxide, oxides of nitrogen, oxides of sulfur, carbon dioxide.

Fire.
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.

Health.
Exposure effects
May cause liver and kidney damage.
   Ingestion
May cause central nervous system depression, kidney damage, and liver damage. The toxicological properties of this substance have not been fully investigated. May be harmful if swallowed. Ingestion of anilinonaphthalene, a similar compound, causes acute vascular changes in the liver, lungs and brain as a result of venous congestion.
   Inhalation
Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. May cause narcotic effects in high concentration. Exposure to similar compounds has caused weight loss, blood changes, and lung damage.
   Skin
Causes skin irritation. Similar compounds have been shown to cause hypersensitivity to light and acne.
   Eyes
Causes eye irritation.

First aid
 
   Ingestion
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid. Wash mouth out with water.
   Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
   Skin
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
   Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
