What is the common term for pepper spray used in law enforcement?

The common term for pepper spray used in law enforcement is "chemical agent." This designation reflects that pepper spray is a type of chemical weapon designed to incapacitate a suspect and control situations that may escalate. It contains oleoresin capsicum (OC), an extract from hot peppers, which causes intense irritation and discomfort when applied, thus helping law enforcement officers manage encounters safely and effectively. The use of "chemical agent" underlines its classification as a non-lethal means of subduing individuals and restoring order without resorting to lethal force.

Other terms like "self-defense spray" and "defense spray" might describe the function of pepper spray but do not carry the same emphasis on its classification as a chemical substance used for law enforcement purposes. "Irritant spray" is a more generic term that could refer to various types of sprays used for self-defense or crowd control but is less specific than "chemical agent."
