What risk considerations exist for bystanders and responders during deployment?

• A. Only the risk of contact with spray on skin.
• B. Secondary exposure from drift, close proximity to spray, enclosed spaces increasing concentration, and potential PPE contamination.
• C. The spray always dissipates immediately outdoors.
• D. There are no risks to bystanders.

Answer: (B)

When OC spray is deployed, the main idea is that risk extends beyond the person targeted to include bystanders and responders through several exposure pathways. Secondary exposure from drift means spray particles can be carried by air currents away from the target and reach people nearby, even if they weren’t sprayed directly. Being in close proximity increases the chance of inhaling aerosols or having spray contact the eyes, nose, or skin. Enclosed spaces worsen exposure because there’s less ventilation, so the concentration can rise and linger, intensifying irritation and potential airway effects. PPE contamination is another key factor: OC residue can cling to protective gear, gloves, or equipment and then be transferred to the wearer’s face or to others when doffing, handling surfaces, or contacting skin or eyes.

This makes the option that highlights multiple risk pathways the best choice. Saying there’s only risk from skin contact, or that outdoors everything dissipates immediately, or that there are no risks, misses these important avenues of exposure and safety implications for everyone nearby and involved in the response.
