General Description
A white crystalline solid. Melting point 281°C. Practically insoluble in water. Water slurry mitigates explosion hazard. Used in solid propellants and explosives. The primary hazard is the blast effect and not flying projectiles and fragments.

Insoluble in water.
Fire Hazard
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

MAY EXPLODE AND THROW FRAGMENTS 1600 METERS (1 MILE) OR MORE IF FIRE REACHES CARGO. For information on "Compatibility Group" letters, refer to Glossary section. (ERG, 2020)
Health Hazard
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

Fire may produce irritating, corrosive and/or toxic gases. (ERG, 2020)
Reactivity Profile
CYCLOTETRAMETHYLENE TETRANITRAMINE, [WET WITH >= 10% WATER] is a high explosive. May begin a vigorous reaction that culminates in a detonation if mixed with reducing agents, including hydrides, sulfides and nitrides. May explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water. Presence of metal oxides increases thermal sensitivity. Wetting reduces sensitivity toward detonation.

Response Recommendations

Isolation and Evacuation
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area immediately for at least 500 meters (1/3 mile) in all directions.

LARGE SPILL: Consider initial evacuation for 800 meters (1/2 mile) in all directions.

FIRE: If rail car or trailer is involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, initiate evacuation including emergency responders for 1600 meters (1 mile) in all directions. (ERG, 2020)
Firefighting
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

CARGO FIRE: DO NOT fight fire when fire reaches cargo! Cargo may EXPLODE! Stop all traffic and clear the area for at least 1600 meters (1 mile) in all directions and let burn. Do not move cargo or vehicle if cargo has been exposed to heat.

TIRE OR VEHICLE FIRE: Use plenty of water - FLOOD it! If water is not available, use CO2, dry chemical or dirt. If possible, and WITHOUT RISK, use unmanned master stream devices or monitor nozzles from maximum distance to prevent fire from spreading to cargo area. Pay special attention to tire fires as re-ignition may occur. Stand by, at a safe distance, with extinguisher ready for possible re-ignition. (ERG, 2020)
Non-Fire Response
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. DO NOT OPERATE RADIO TRANSMITTERS WITHIN 100 METERS (330 FEET) OF ELECTRIC DETONATORS. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST. (ERG, 2020)
Protective Clothing
Excerpt from ERG Guide 112 [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

First Aid
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

Call 911 or emergency medical service. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Move victim to fresh air if it can be done safely. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. (ERG, 2020)
