Unless rescue is required, the incident commander should not commit personnel to the hot zone until what is available?

• A. Decontamination capabilities
• B. Medical support
• C. Air monitoring
• D. Communication plan

Answer: (A)

Decontamination capabilities must be in place before sending personnel into the hot zone. The hot zone contains the highest level of hazard, and responders can become contaminated simply by performing tasks there. Having decon ready ensures that once personnel are exposed, there is a safe, organized way to remove contaminants from PPE and gear before they exit to less hazardous areas, preventing secondary spread and enabling a safe return to operations or exit from the scene.

Air monitoring, medical support, and a solid communication plan are all important for overall incident safety and coordination, but they do not address the immediate need to prevent contaminant transfer to responders and others. Decontamination setup directly mitigates that risk, making it the critical prerequisite before entry unless a rescue operation requires otherwise.
