TRIMETHYLHEXAMETHYLENEDIAMINES

A colorless to light yellow liquid. Insoluble in water and less dense than water. Contact may severely irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make other chemicals.

none

Insoluble in water.

Special Hazards of Combustion Products: May contian toxic and irritating gases including NOx.

Behavior in Fire: May generate toxic and irritating gases. (USCG, 1999)

INHALATION: Irritating to mucous membranes. EYES and SKIN: Irritation. INGESTION: May be harmful if swallowed. (USCG, 1999)

Amines, such as TRIMETHYLHEXAMETHYLENEDIAMINE, are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

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)

Excerpt from ERG Guide 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, RAIL TANK CARS OR HIGHWAY TANKS: 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 in direct contact with flames. (ERG, 2024)

Excerpt from ERG Guide 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, 2024)

Wear self-contained (positive pressure if available) breathing apparatus (with acid filter like that used for ammonia) and full protective clothing. (USCG, 1999)

No information available.

INHALATION: Remove victim to fresh air. Keep victim warm and quiet. If breathing has stopped, give artificial respiration. If breathing is difficult, administer oxygen.

EYES or SKIN: Immediately flush with running water for at least 15 minutes. (Hold eyelids open if necessary.) Keep victim quiet and maintain normal body temperature. Remove and isolate contaminated clothing and shoes at site.

INGESTION: If victim is unconscious or having convulsions, do nothing except maintain normal body temperature and seek medical aid. (USCG, 1999)
