Which classification of spray is primarily known for causing an inflammatory effect?

The classification of spray that is primarily known for causing an inflammatory effect is OC, which stands for Oleoresin Capsicum. OC spray, commonly referred to as pepper spray, is derived from cayenne peppers and is known for its potent inflammatory properties. When used against a subject, OC causes immediate inflammation of the mucous membranes, resulting in symptoms such as intense burning sensations in the eyes, difficulty breathing, and severe irritation of the skin. This inflammatory reaction is key to its effectiveness as a nonlethal weapon, as it incapacitates individuals by causing temporary disorientation and pain, allowing for the control of aggressive behavior.

In contrast, other sprays like CS, which is a synthetic compound, primarily cause irritation rather than full-fledged inflammation, and CN, which is a tear gas, is primarily an irritant as well. Additionally, PE, which stands for Pava or a similar agent, has different effects and mechanisms of action. Understanding the specific effects of each classification helps in determining the appropriate use of these nonlethal weapons in various scenarios.
