How long do most OC irritant effects last after exposure?

• A. Symptoms typically peak within minutes and resolve within 15–60 minutes; longer in sensitive individuals or with re-exposure.
• B. Effects last for several days.
• C. Effects never resolve.
• D. Effects last only a few seconds.

Answer: (D)

OC irritant effects unfold quickly but don’t end in a flash. When exposed, the eyes and mucous membranes react and the burning, tearing, coughing, and irritation typically peak within minutes. From there, the symptoms usually fade as the spray dissipates and the tissues recover, which is why most people find them resolve within a short window—about 15 to 60 minutes. Some individuals may experience longer-lasting effects, especially if they are particularly sensitive or if exposure is repeated, but lasting days is not the typical pattern. The notion of effects lasting only a few seconds underestimates how long the irritation and discomfort persist after exposure.
