K: Article containing both an explosive substance and a toxic chemical agent (1.2K, 1.3K) L Explosive substance or article containing an explosive substance and presenting a special risk (e.g., due to water-activation or presence of hypergolic liquids, phosphides, or pyrophoric substances) needing isolation of each type (1.1L, 1.2L, 1.3L ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
Red water (also known as "Sellite water") is produced during the process used to purify the crude TNT. It has a complex composition containing more than a dozen aromatic compounds, but the principal components are inorganic salts ( sodium sulfate , sodium sulfite , sodium nitrite and sodium nitrate ) and sulfonated nitroaromatics .
Both operations were connected to a multi-state illegal fireworks distribution and production ring, and multiple people were eventually sent to prison for their involvement in both incidents. [ 18 ] The 1986 San Francisco fireworks disaster occurred when an illegal machine making M-80s failed, resulting in widespread destruction of a city block ...
According to a 2017 report by the Dutch Safety Board, 25% of all fireworks tested failed to meet safety standards and were banned from sale. [2] Since 2010, safety testing of fireworks is required in the entire European Union, but companies are allowed to test their products in one member state before importing and selling them in another.

Some of the sucrose does not burn, but merely decomposes at the high temperature, giving off elemental carbon and water vapor: [4] C 12 H 22 O 11 (s) → 12 C(s) + 11 H 2 O(g) The carbon in the reaction makes the snake black. The overall process is exothermic enough that the water produced in the reactions is vaporized.
Tovex, a form of water gel explosive. A water-gel explosive is a fuel-sensitized explosive mixture consisting of an aqueous ammonium nitrate solution that acts as the oxidizer. [1] Water gels that are cap-insensitive are referred to under United States safety regulations as blasting agents. Water gel explosives have a jelly-like consistency and ...
Colored fireworks were developed from earlier (possibly Han dynasty or soon thereafter) Chinese application of chemical substances to create colored smoke and fire. [13] Such application appears in the Huolongjing (14th century) and Wubeizhi (preface of 1621, printed 1628), which describes recipes, several of which used low-nitrate gunpowder ...
