The duration of OC effects at 10% concentration is typically about?

• A. Approximately 45 minutes.
• B. Several hours.
• C. A few days.
• D. Several seconds.

Answer: (A)

The main idea here is how long the peak effects of OC spray typically last at a common strong concentration. At 10% OC, the uncomfortable symptoms—burning eyes, tearing, coughing, temporary impaired vision—rise quickly after exposure and then gradually fade as the irritant is washed away and your tissues recover. In most cases, the full, noticeable effects resolve in about 45 minutes. Some irritation may linger briefly, but the majority of people regain normal function within roughly an hour. This is why longer durations like several hours or days aren’t the norm for standard exposure, and only a very brief, seconds-long onset would miss the time it takes for the irritation to develop and then subside. If decontamination is prompt—flush with clean water, move to fresh air, avoid rubbing the eyes—the duration can be shortened further.
