CR gas, also known as dibenzoxazepine, is a type of [[tear gas]] that is used for [[riot control]] and [[crowd dispersal]]. It is a potent [[lachrymatory agent]], which means it causes tearing and irritation of the eyes and respiratory system. CR gas is considered to be more potent than other tear gases such as [[CS gas]] and [[CN gas]].


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.  
==Chemical Properties==
CR gas is a pale yellow crystalline solid at room temperature. It is chemically classified as a dibenz[b,f][1,4]oxazepine. The chemical formula for CR gas is C13H9NO, and it has a molar mass of 195.22 g/mol. It is insoluble in water but can be dissolved in organic solvents such as acetone and benzene.


== Composition and Effects ==
==Mechanism of Action==
CR gas works by irritating the mucous membranes of the eyes, nose, mouth, and respiratory tract. Upon exposure, individuals experience a burning sensation in the eyes, excessive tearing, coughing, and difficulty breathing. The effects are usually temporary, lasting from 15 to 30 minutes after exposure has ceased.


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.  
==Uses==
CR gas is primarily used by law enforcement agencies for [[riot control]] and [[crowd management]]. It is deployed in situations where non-lethal force is necessary to disperse crowds or subdue individuals. CR gas can be delivered via grenades, aerosol sprays, or other dispersal devices.


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.  
==Health Effects==
[[File:Gas mask.jpg|thumb|left|A gas mask is used to protect against inhalation of CR gas.]]
While CR gas is intended to be non-lethal, it can cause significant discomfort and health effects. Short-term exposure can lead to:
* Severe eye irritation and tearing
* Skin irritation and redness
* Respiratory distress, including coughing and difficulty breathing
* Nausea and vomiting


== Use in Riot Control ==
Prolonged or high-level exposure can exacerbate these symptoms and may lead to more serious health issues, particularly in individuals with pre-existing respiratory conditions such as [[asthma]].


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.  
==Safety and Protection==
To protect against CR gas exposure, individuals can use [[gas masks]] or respirators equipped with appropriate filters. Protective clothing can also help prevent skin contact. In the event of exposure, moving to fresh air and rinsing the affected areas with water can help alleviate symptoms.


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.  
==Legal and Ethical Considerations==
 
The use of CR gas is subject to legal and ethical scrutiny. While it is considered a non-lethal weapon, its use in [[crowd control]] situations raises concerns about human rights and the potential for misuse. International regulations and guidelines govern the deployment of CR gas to ensure it is used appropriately and safely.

An overview of CR gas, its properties, uses, and effects


CR Gas[edit]

CR gas, also known as dibenzoxazepine, is a type of tear gas that is used for riot control and crowd dispersal. It is a potent lachrymatory agent, which means it causes tearing and irritation of the eyes and respiratory system. CR gas is considered to be more potent than other tear gases such as CS gas and CN gas.

Chemical Properties[edit]

CR gas is a pale yellow crystalline solid at room temperature. It is chemically classified as a dibenz[b,f][1,4]oxazepine. The chemical formula for CR gas is C13H9NO, and it has a molar mass of 195.22 g/mol. It is insoluble in water but can be dissolved in organic solvents such as acetone and benzene.

Mechanism of Action[edit]

CR gas works by irritating the mucous membranes of the eyes, nose, mouth, and respiratory tract. Upon exposure, individuals experience a burning sensation in the eyes, excessive tearing, coughing, and difficulty breathing. The effects are usually temporary, lasting from 15 to 30 minutes after exposure has ceased.

Uses[edit]

CR gas is primarily used by law enforcement agencies for riot control and crowd management. It is deployed in situations where non-lethal force is necessary to disperse crowds or subdue individuals. CR gas can be delivered via grenades, aerosol sprays, or other dispersal devices.

Health Effects[edit]

A gas mask is used to protect against inhalation of CR gas.

While CR gas is intended to be non-lethal, it can cause significant discomfort and health effects. Short-term exposure can lead to:

  • Severe eye irritation and tearing
  • Skin irritation and redness
  • Respiratory distress, including coughing and difficulty breathing
  • Nausea and vomiting

Prolonged or high-level exposure can exacerbate these symptoms and may lead to more serious health issues, particularly in individuals with pre-existing respiratory conditions such as asthma.

Safety and Protection[edit]

To protect against CR gas exposure, individuals can use gas masks or respirators equipped with appropriate filters. Protective clothing can also help prevent skin contact. In the event of exposure, moving to fresh air and rinsing the affected areas with water can help alleviate symptoms.

Legal and Ethical Considerations[edit]

The use of CR gas is subject to legal and ethical scrutiny. While it is considered a non-lethal weapon, its use in crowd control situations raises concerns about human rights and the potential for misuse. International regulations and guidelines govern the deployment of CR gas to ensure it is used appropriately and safely.
