TRIS(2-CHLOROETHYL)AMINE

Liquid with faint odor of fish and soap, no odor when pure. Used as a delayed-action casualty military agent.

none

Acts as a strong base in water.

When heated to decomposition, it emits chloride and nitrogen oxides. No action on metals or other materials if material is kept dry. Avoid decomposing heat. (EPA, 1998)

Most toxic of the nitrogen mustards. The median lethal dose for inhalation is 1,500 mg-min/m3; for skin absorption (masked personnel) is 10,000 mg-min/m3. The medium incapacitating dose for eye injury is 200 mg-min/m3; for skin absorption is 2,500 mg-min/m3. (EPA, 1998)

When dissolved in water, it is a strong base; reacts violently with strong oxidants and acids ; attacks copper and copper compounds. [Handling Chemicals Safely 1980. p. 123]; reacts with hypochlorites to give N-chloroamines, some of which are explosives when isolated [Bretherick 1979. p. 108].

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: If this material is being used as a weapon, see ERG Table 1 - Initial Isolation and Protective Action Distances on the 153 datasheet for unassigned UN/NA numbers . Otherwise 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)

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)

Avoid inhalation and skin contact. (Non-Specific -- Poisonous Liquid, n.o.s.) Do not touch spilled material; stop leak if you can do so without risk. Use water spray to reduce vapors.

Small spills: absorb with sand or other noncombustible absorbent material and place into containers for later disposal.

Large spills: dike far ahead of spill for later disposal. (EPA, 1998)

For emergency situations, wear a positive pressure, pressure-demand, full facepiece self-contained breathing apparatus (SCBA) or pressure- demand supplied air respirator with escape SCBA and a fully-encapsulating, chemical resistant suit. (EPA, 1998)

Warning: Tris(2-chloroethyl)amine is a strong irritant. Direct contact may result in severe dermal or corneal burns. Effects may be delayed.

Signs and Symptoms of Tris(2-Chloroethyl)amine Exposure: Signs and symptoms of acute exposure to tris(2-chloroethyl)amine may include strong irritation or burning of the eyes, skin, and respiratory tract. Blisters, local phlebitis (irritation of a vein) and erythema (redness of the skin) may be noted. It may cause nausea, vomiting, and severe esophageal or gastrointestinal tract irritation if ingested. Bronchopneumonia, suppression of bone marrow activity, and hearing loss are possible longer term symptoms.

Emergency Life-Support Procedures: Acute exposure to tris(2-chloroethyl)amine may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination.

Inhalation Exposure:
1. Move victims to fresh air. Emergency personnel should avoid self-exposure to tris(2-chloroethyl)amine.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
4. Rush to a health care facility.

Dermal/Eye Exposure:
1. Remove victims from exposure. Emergency personnel should avoid self-exposure to tris(2-chloroethyl)amine.
2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
3. Remove contaminated clothing as soon as possible.
4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes. Speed in removing material from the eyes is of extreme importance.
5. Wash exposed skin areas thoroughly with soap and water. Speed in removing material from the skin is of extreme importance.
6. Obtain authorization and/or further instructions from the local hospital for performance of other invasive procedures.
7. Rush to a health care facility.

Ingestion Exposure:
1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support.
2. DO NOT induce vomiting or attempt to neutralize.
3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures.
4. Give the victims water or milk: children up to 1 year old, 125 mL (4 oz or 1/2 cup); children 1 to 12 years old, 200 mL (6 oz or 3/4 cup); adults, 250 mL (8 oz or 1 cup). Water or milk should be given only if victims are conscious and alert.
5. Rush to a health care facility. (EPA, 1998)
