What is the first level of decontamination referred to?

The first level of decontamination is referred to as "Immediate" decontamination. This stage occurs directly after exposure to a harmful material, such as a chemical, biological, or radiological agent, and is focused on rapidly reducing contamination to minimize the potential for harm. The primary goal of immediate decontamination is to remove or neutralize contaminants from the skin, clothing, and equipment as quickly as possible, often through simple means such as washing with soap and water or employing specialized decontamination wipes. This quick action helps prevent further absorption of contaminants and reduces the risk of injury or illness.

Other levels of decontamination, such as operational and preventative, serve different purposes and happen at varying time frames after the initial exposure and may involve more complex procedures that are implemented once immediate risks have been addressed.
