How long should a subject be monitored after OC deployment?

• A. 15 minutes
• B. 30 minutes
• C. 45 minutes
• D. 60 minutes

Answer: (C)

After OC deployment, there’s a need to observe the subject for any evolving or delayed reactions and to ensure they can be managed safely before further handling. The effects of pepper spray can irritate the eyes and airways, cause coughing or breathing difficulty, and sometimes symptoms persist or appear after the initial exposure. A monitoring window of about 45 minutes provides enough time to see if symptoms peak, begin to resolve with decontamination and basic care, or require medical attention. It also supports safe decision-making about custody and transport.

Choosing a shorter period (15 or 30 minutes) risks missing late-onset symptoms, while a longer period (60 minutes) may unnecessarily tie up resources. The 45-minute interval balances safety with practicality, ensuring the subject is stabilized before proceeding.
