What is one of the first steps in the decontamination process?

One of the first steps in the decontamination process is the identification of the contaminant. This crucial step involves determining the chemical or biological agent involved in an incident, as it informs all subsequent actions necessary for effective decontamination and safety. Understanding the nature of the contaminant allows responders to select appropriate decontamination methods, protective equipment, and safety measures that are specifically tailored to handle that substance.

Identifying the contaminant also aids in assessing potential health risks, the required level of personal protective equipment needed, and the procedures for safely managing exposure. Therefore, accurate identification is paramount for ensuring the safety of both personnel and the environment during decontamination.

Although other options play essential roles in the overall response process, effective decontamination begins with knowing what responders are dealing with, making it a critical first step.
