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 hose holders 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, 2016)

9. Physical and chemical properties
Physical state | 1H-tetrazole is an odorless white to light-yellow crystalline powder. Mp:1 55-157°C. When heated to decomposition it emits toxic oxides of nitrogen fumes. Can explode if exposed to shock or heat from friction or fire. The primary hazard is from blast effect where the entire load can explode instantaneously and not from flying projectiles and fragments. |

10. Stability and reactivity
10.1 Reactivity
Soluble in water (23 g/100 mL at 20°C) Reacts slowly with water (moisture) with release of corrosive gases (ammonia, nitrogen oxides).
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
1-H-TETRAZOLE is stable at normal temperature and pressure but decomposes rapidly and explosively if heated above its melting point of 155-157° C (Chem. Rev 1947, 41, 5). Presents an extreme risk of explosion by shock, friction, fire or other sources of ignition. Reacts violently with strong oxidizers. Reacts with acidic materials (strong acids, acid anhydrides and acid chlorides) to release heat and toxic and corrosive gases. Reacts with some active metals to give new materials that are shock-sensitive explosives. Can react exothermically with reducing agents. Heating or burning releases toxic and corrosive nitrogen oxides, carbon monoxide, carbon dioxide. [MSDS Document number : 4330220A] Soluble in water. Soluble in acetonitrile. Dilute solutions (2-3% by mass) of 1-H-TETRAZOLE in acetonitrile are used in biochemistry for DNA synthesis.
