In the event of exposure to a chemical agent, what is a critical first step?

When exposed to a chemical agent, one of the most critical first steps is to remove clothing if contaminated. This action is vital because clothing can absorb and retain harmful agents, prolonging exposure and potentially increasing the risk of serious injury or death. By taking off contaminated clothing, you significantly reduce the amount of the chemical agent that comes into contact with your skin and body, which is essential for minimizing the potential harmful effects.

Removing contaminated clothing also facilitates the next steps in decontamination, such as thorough washing of the skin. It is important to address contamination quickly, as chemical agents can have immediate and severe effects depending on their nature and concentration.
