What are the two methods used for dispersing CS?

The correct answer identifies pyrotechnics and aerosol as the two methods for dispersing CS, commonly known as tear gas. Understanding these methods is essential for law enforcement operations and crowd control situations.

Aerosol dispersal is widely utilized due to its effectiveness in spreading the chemical agent quickly through the air, ensuring it reaches a broad area and can effectively incapacitate individuals without requiring direct contact. This method can be employed in various delivery systems, including canisters and handheld devices.

The pyrotechnics method involves using heat and combustion to disperse the CS agent. This technique typically results in a larger area of coverage and is often utilized for rapid dispersal in circumstances where immediate effect is needed. This method may deploy the agent in a more concentrated form, leading to a quicker incapacitating outcome.

Other methods mentioned in the options, such as liquid and gas, refer to other forms of dispersion but do not accurately describe the conventional techniques specifically associated with CS dispersal.
