Final answer:
Before entering a hot zone, technical decontamination (technical decon) must be set up to ensure the safety of entry personnel and prevent the spread of hazardous substances. Proper personal protective clothing is also a must. Instructing victims to disrobe can be a part of the decontamination process.
Step-by-step explanation:
Before entry personnel enter the hot zone, several measures need to be in place to ensure their safety and the effectiveness of the operation. Among the options provided, setting up technical decon is a critical step. Technical decontamination involves the establishment of controlled areas to prevent the spread of hazardous substances and to reduce the contamination on personnel and equipment. This setup allows for a systematic approach to cleaning and makes sure that first responders are not carrying hazardous materials back into clean areas, thereby protecting additional response personnel and the public.
Personal protective clothing, including protective coats, face protection, and cut-resistant gloves, is essential for health and safety. First responders should be properly dressed in fire-resistant clothing and breathing apparatus when needed. Avoiding flashy or revealing clothes and maintaining proper personal hygiene are basic precautions to prevent additional risks.
Victims, if they are to be moved or treated, must be handled carefully, and often they are the ones who are decontaminated first, depending on the situation. Procedures such as instructing victims to disrobe might occur to prevent the spread of contamination.
