NREMT Advanced Emergency Medical Technician (AEMT) Practice Test

The area with the actual hazard is the hot zone, where the contaminant is present and exposure risk is highest; entry into this zone requires appropriate PPE to protect against skin contact, inhalation, and other routes of exposure. The warm zone sits between the hot and cold zones as a buffer where decontamination and PPE donning/doffing occur, and the cold zone is the clean area where operations, command, and medical support are conducted away from contamination. The public assembly area is not part of the incident’s hazardous zones.
