Which method is recommended for initial decontamination of a victim?

Wetting the victim with water is the recommended method for initial decontamination because it helps to remove contaminants, such as chemicals or biological agents, from the surface of the skin. This process can dilute and wash away harmful substances, thereby reducing the risk of absorption through the skin and minimizing potential injury or infection.

In scenarios where a victim has been exposed to hazardous materials, immediate decontamination is critical to prevent further exposure and to protect both the victim and first responders. Water serves as a neutral medium that can effectively disperse many types of contaminants, allowing for a safer environment.

The other methods outlined do not provide immediate or effective decontamination. Applying antiseptic ointment should occur after initial decontamination has taken place, as it does not effectively remove contaminants and may even trap them against the skin. Letting the victim rest for an hour does not address the potential dangers posed by any contaminants present on their body. Wrapping the victim in plastic could create a barrier that retains contaminants against the skin and doesn't initiate the washing process necessary for thorough decontamination.
