Final answer:
Before doing any work in the hot zone, responders should establish the decontamination corridor and decontaminate their PPE.
Step-by-step explanation:
Before doing any work in the hot zone, responders should establish the decontamination corridor. This is important to prevent the spread of hazardous materials and ensure the safety of both the responders and the victims. By setting up a decontamination corridor, responders can safely remove their contaminated Personal Protective Equipment (PPE) and minimize the risk of contamination to themselves and others.
Decontaminating their PPE is also a crucial step before entering the hot zone. This ensures that the responders' protective gear is free from hazardous substances and ready to use. Decontamination methods may vary depending on the specific contaminants involved, but it typically involves washing the PPE with appropriate solutions or disinfectants.
