In terms of PPE requirements, how do personnel operate in the warm zone?

In the warm zone, personnel typically operate in an area that serves as a buffer between the contaminated hot zone and the safe cold zone. This zone is where decontamination processes occur, and while some level of contamination may be present, it is generally less hazardous than in the hot zone, where full protective measures are necessary due to high levels of exposure risk.

The requirement for wearing lower levels of personal protective equipment (PPE) in the warm zone is designed to balance safety with the need for mobility and functionality. Personnel are still protected to a degree, as they encounter potential contaminants, but they do not need the full protective suits required in the hot zone.

In contrast, wearing full protective suits is typically necessary only in the hot zone due to the higher risk of exposure. No PPE requirement or only standard uniforms would not provide adequate protection given the possible hazards even in the warm zone. Thus, personnel need to maintain a level of readiness without the extensive protection needed for the most dangerous areas of the incident scene.
