What are decontamination recommendations for vehicle interiors after OC exposure?

• A. Ventilate for extended periods; clean interior surfaces with soap and water if possible; remove contaminated materials if safe; document.
• B. Sealing the vehicle and leaving it.
• C. Wiping with dry cloth only.
• D. No decontamination needed.

Answer: (B)

Decontaminating a vehicle after OC exposure centers on diluting the irritant vapors and physically removing OC residue to protect people from continued exposure. The recommended approach is to ventilate the vehicle for an extended period to exchange the air and reduce vapor concentration. Then clean interior surfaces with soap and water when possible, which helps lift and remove the oily OC residue from plastics, fabrics, and other materials. If safe to do so, remove contaminated items such as seat covers, floor mats, or clothing to prevent ongoing exposure and dispose of or treat them properly. Document the actions taken and any observations for accountability and future safety. Sealing the vehicle and leaving it traps vapors and prolongs exposure, wiping only with a dry cloth may spread residue rather than remove it, and no decontamination leaves occupants at risk.
