Which step is part of first aid for a civilian indoors exposed to OC spray?

• A. Move to fresh air
• B. Stay indoors and wait for symptoms
• C. Apply soap to eyes
• D. Rinse with hot water

Answer: (A)

When someone is exposed to OC spray, the immediate priority is to reduce further exposure by getting into fresh air. Moving to an open, well-ventilated environment lowers the amount of irritant they inhale and helps eyes and airways recover more quickly. Indoors, lingering spray can keep affecting the person, so exiting to outdoor air is the best first aid step. After reaching fresh air, continue with other measures as needed, such as avoiding rubbing the eyes, removing contact lenses if present, and flushing the eyes with clean water or saline. Do not use soap on the eyes or hot water to rinse—soap can irritate and hot water can worsen symptoms.
