What is the typical duration of OC spray effects?

• A. Effects last all day.
• B. Most effects subside within 15 to 60 minutes, though residual irritation can linger.
• C. Effects subside in 5 minutes.
• D. Effects never subside.

Answer: (B)

OC spray effects are temporary and typically not long-lasting. After exposure, the strongest symptoms—burning eyes, excessive tearing, coughing, and a runny nose—usually peak quickly and subside within about 15 to 60 minutes. Some residual irritation, such as tearing or a dry, irritated throat, can linger for a bit longer, but the overall effects aren’t expected to persist all day. Individual factors like the amount sprayed, ventilation, and prior exposure can influence the exact duration, but the common pattern is a return toward normal once the primary irritation fades. This is why the choice stating that most effects subside within 15 to 60 minutes, with possible lingering irritation, best fits typical OC spray duration.
