CR gas

CR gas is a type of tear gas used for riot control. It was developed by the British Ministry of Defence and is considered more potent than CS gas, another commonly used tear gas.

History

CR gas was first synthesized in the 1960s by the British Ministry of Defence as a replacement for CS gas. It was used extensively in Northern Ireland during The Troubles, a period of conflict that lasted from the late 1960s to the late 1990s.

Composition and Effects

CR gas is a nitrile compound, specifically a cyanocarbon. It is a white solid at room temperature and can be dispersed as an aerosol. When inhaled or comes into contact with the skin or eyes, it causes severe irritation and a burning sensation. The effects are immediate and can last for several hours after exposure.

Unlike CS gas, CR gas cannot be neutralized with water and requires special decontamination procedures. It is also more toxic and can cause serious health problems if inhaled in large quantities.

Use in Riot Control

CR gas is used in riot control due to its potent effects and the difficulty in decontaminating areas where it has been used. It is often used in combination with other riot control agents such as pepper spray or rubber bullets to disperse crowds.

Despite its effectiveness, the use of CR gas has been controversial due to its potential health risks. Several countries, including the United States, have banned its use in riot control.
