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.

The Hazard fields include special hazard alerts air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.

Fire Hazard
Excerpt from ERG Guide 112 [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. (ERG, 2024)
Health Hazard
Excerpt from ERG Guide 112 [Explosives - Division 1.1, 1.2, 1.3 or 1.5]:

Fire may produce irritating, corrosive and/or toxic gases. (ERG, 2024)
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.
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. More info about absorbents, including situations to watch out for...

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 112 [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, 2024)
Firefighting
Excerpt from ERG Guide 112 [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, 2024)
Non-Fire Response
Excerpt from ERG Guide 112 [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, 2024)
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, 2024)

First Aid
Excerpt from ERG Guide 112 [Explosives - Division 1.1, 1.2, 1.3 or 1.5]:

Refer to the "General First Aid" section. (ERG, 2024)

The Physical Property fields include properties such as vapor pressure and boiling point, as well as explosive limits and toxic exposure thresholds The information in CAMEO Chemicals comes from a variety of data sources.

Note: For Vapor Density and Specific Gravity, comparing the value to 1.0 can tell you if the chemical will likely sink/rise in air or sink/float in fresh water (respectively). Short phrases have been added to those values below as an aid. However, make sure to also consider the circumstances of a release. The Vapor Density comparisons are only valid when the gas escaping is at the same temperature as the surrounding air itself. If the chemical is escaping from a container where it was pressurized or refrigerated, it may first escape and behave as a heavy gas and sink in the air (even if it has a Vapor Density value less than 1). Also, the Specific Gravity comparisons are for fresh water (density 1.0 g/mL). If your spill is in salt water (density about 1.027 g/mL), you need to adjust the point of comparison. There are some chemicals that will sink in fresh water and float in salt water.
