General Description
Colorless to light yellow liquid with a strong odor of ammonia. Floats and mixes with water. (USCG, 1999)

Hazards

Reactivity Alerts
none
Air & Water Reactions
Water soluble.
Fire Hazard
Special Hazards of Combustion Products: Toxic nitrogen oxides may form in a fire. (USCG, 1999)
Health Hazard
Inhalation of vapor causes irritation of the mucous membranes of the nose and throat, and lung irritation with respiratory distress and cough. Headache, nausea, faintness, and anxiety can occur. Exposure to vapor produces eye irritation with lachrymation, conjunctivitis, and corneal edema resulting in halos around lights. Direct local contact with liquid is known to produce severe and sometimes permanent eye damage and skin burns. Vapors may also produce primary skin irritation and dermatitis. (USCG, 1999)
Reactivity Profile
In presence of moisture, BENZYLAMINE may weakly corrode some metals. Liquid will attack some plastics (USCG, 1999). Neutralize acids to form salts plus water in exothermic reactions. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated in combination with strong reducing agents, such as hydrides.
Belongs to the Following Reactive Group(s)

Response Recommendations

Isolation and Evacuation
Excerpt from ERG Guide 153 [Substances - Toxic and/or Corrosive (Combustible)]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
Firefighting
Fire Extinguishing Agents Not to Be Used: Water may be ineffective.

Fire Extinguishing Agents: Alcohol foam, dry chemical, carbon dioxide (USCG, 1999)
Non-Fire Response
Neutralizing Agents for Acids and Caustics: Flush with water. (USCG, 1999)
Protective Clothing
Self-contained breathing apparatus; goggles or face shield; rubber gloves (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
First Aid
INHALATION: remove victim from exposure; if breathing is difficult, administer oxygen; if breathing has stopped, begin artificial respiration.

EYES or SKIN: wash with copious amounts of water for 15 min. (USCG, 1999)
