What is the typical onset time for OC spray effects?

• A. Several hours
• B. 5-10 minutes
• C. Immediately after exposure only
• D. Seconds to a minute

Answer: (D)

OC spray effects show up very quickly because the irritants act on the eyes and mucous membranes right away. When the spray contacts the face, the capsaicin compounds irritate sensory nerves, causing tearing, burning, coughing, throat irritation, and a strong urge to rub or blink. Because these nerves respond so fast, most people start feeling noticeable effects within seconds, usually by about a minute after exposure. It isn’t something that only happens after a long delay, nor is it limited to an instantaneous event that ends at exposure—the symptoms tend to develop quickly and can persist for several minutes as the irritation runs its course. Factors like concentration, distance from the spray, and wind can affect how intense the onset is, but the typical window remains seconds to a minute.
