none
Air & Water Reactions
Water soluble.
Fire Hazard
Special Hazards of Combustion Products: Toxic fumes of NO x (USCG, 1999)
Health Hazard
INHALATION: Burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. EYES AND SKIN: Extremely destructive to mucous membranes, upper respiratory tract, eyes and skin. Causes burns on short contact. (USCG, 1999)
Reactivity Profile
N-AMINOETHYLPIPERAZINE neutralizes 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)
- Amines, Phosphines, and Pyridines
Potentially Incompatible Absorbents
Use caution: Liquids with this reactive group classification have been
known to react with the

- Mineral-Based & Clay-Based Absorbents
Response Recommendations
Isolation and Evacuation
Excerpt from 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 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
Excerpt from 153
[Substances - Toxic and/or Corrosive (Combustible)]:
SMALL FIRE: Dry chemical, CO2 or water spray.
LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. If it can be done safely, move undamaged containers away from the area around the fire. Dike runoff from fire control for later disposal.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2020)
Non-Fire Response
Excerpt from 153
[Substances - Toxic and/or Corrosive (Combustible)]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2020)
Protective Clothing
Wear approved respirator, chemical resistant gloves, safety goggles rubber boots, and protective clothing. (USCG, 1999)

First Aid
INHALATION: Remove to fresh air; if not breathing, give artificial respiration; if breathing difficult, give oxygen.
SKIN: Remove contaminated clothing and shoes; flush affected areas with plenty of water.
EYES: Hold eyelids open and flush with water for at least 15 minutes. (USCG, 1999)
