OC Defense Spray Certification Practice Test

OC spray works by triggering acute irritation and inflammation of exposed tissues. It contains capsaicin-rich oleoresin capsicum that directly irritates mucous membranes and skin. This irritation occurs because it activates pain receptors on sensory neurons (the TRPV1 receptors), leading to a rapid inflammatory response with burning, tearing, coughing, eyelid swelling, and temporary impairment of vision. The primary effect is inflammation and irritation, which incapacitates quickly, not any narcotic or sedative effect. It’s not a cooling agent, which would produce a cooling sensation instead. In short, OC spray is classified as an inflammatory agent because its main action is to provoke inflammation and intense irritation rather than sedation, numbness, or cooling.
