Assorted Tear Gas

Tear gas is also called tear gas, and the most common ingredients are acetophenone (CN) and o-chlorobenzylmalononitrile (CS). Among them, CS is the most widely used ingredient at present. It is a chemical substance that can emit tear gas and stimulate tears. It can be launched in the form of spray or grenade. Tear gas is used by police around the world and is widely used in riots to disperse demonstrators.

1. The composition of tear gased

The tear gased generally consists of ingredients such as irritants and solvents. At present, the stimulants used in international hand-held self-defense devices mainly include acetochloroethyl ketone (CN), o-chlorobenzylmalononitrile (CS), capsaicin (OC), piperine, etc., and CR and Other liquid stimulants. Among them, CS is much safer than CN, and has a stronger irritant, while OC and piperine are pure natural and non-toxic preparations, so they are widely used as preferred stimulants. Sometimes two stimulants are used in combination, because some foreign research institutions believe that the composite stimulant combines the advantages of several stimulants and is safer. The solvent is mainly used to dissolve the irritant and other components, and as a carrier for the spray of the irritant. The basic requirements for it are: strong solubility for active ingredients such as stimulants; no chemical reaction with the ingredients in the formula and good compatibility; no harmful substances. At low concentrations, tear gas can make people's eyes irritated, tearing constantly, and it is difficult to open their eyes.

If you encounter tear gased powder, get to a well-ventilated area and your symptoms should clear up quickly. The tear gased cartridges contain magnesium, aluminum, sodium nitrate, barium nitrate and other substances. After detonation, magnesium burns rapidly in the air, emitting dazzling white light containing ultraviolet rays, and at the same time releasing heat to decompose nitrates, which further promotes the combustion of magnesium and aluminum; the tear gas bomb contains volatile liquid bromine, which can stimulate people's sensitive parts - The mucous membranes of the eyes, nose and other organs are tear-jerking. It is sometimes loaded with a poison known as Sies, which can cause profuse tears, violent coughing, and unbearable sneezing, which can lead to death in severe cases.

2. Common types and models of tear gased

One is incendiary tear gas chemical. In order to meet the needs of the public security and armed police forces to deal with emergencies and conduct military training. The principle of action of the incendiary tear gas bomb is as follows: the oxidant in the main charge reacts with the combustible agent, and a large amount of heat and gas generated by the reaction sublimates and evaporates the irritant, and sprays the irritating aerosol from the smoke hole, thereby acting for living goals. The bomb can still function normally in 1-meter-deep water, and is suitable for use in rainy and snowy weather when the water is too deep. The bullet can be hand-thrown or rifle-fired.

The second is the mother-child tear gas. Child-mother tear gas chemical become an important research direction of new anti-riot bombs due to its advantages of rapid smoking, multi-point delivery, and multi-source end effect. When using it, first tear the packaging bag, take out the tear gas cartridge, hold the bullet body and safety sheet firmly with the right hand, put the index finger of the left hand into the pull ring, and pull out the safety pin forcefully. If throwing is not carried out for some reason, the safety pin must be inserted back to its original position to keep the bomb in a safe state.
