Hazards

Reactivity Alerts
none
Air & Water Reactions
Water soluble.
Fire Hazard
Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in fire.

Behavior in Fire: May produce toxic oxides of nitrogen. (USCG, 1999)
Health Hazard
If inhaled may be harmful. Contact may cause burns to skin and eyes. (Organic base.) (USCG, 1999)
Reactivity Profile
N-PROPANOLAMINE neutralizes acids to form salts plus water in an exothermic reaction. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Reacts with strong reducing agents, such as hydrides to generate flammable gaseous hydrogen.
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below.

Response Recommendations

Isolation and Evacuation
Excerpt from 153 Polymerizable warning [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 car or tank truck 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, 2020)
Firefighting
Fire Extinguishing Agents: Small fires: Dry chemical, CO2, water spray or alcohol foam. Large fires: Water spray, fog or alcohol foam. (USCG, 1999)
Non-Fire Response
Neutralizing Agents for Acids and Caustics: Cover spilled material with sodium bisulfate. Flush with water. (USCG, 1999)
Protective Clothing
Wear butyl rubber gloves and face shield or all-purpose canister respirator for spills. Wear self-contained breathing apparatus and full protective clothing for fires. (USCG, 1999)

First Aid
INHALATION: Move victim to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.

SKIN AND EYES: Immediately flush skin or eyes with running water for at least 15 minutes; hold eyelids open if necessary. Remove and isolate contaminated clothing and shoes. Maintain normal body temperature. (USCG, 1999)
