Which of the following will require decontamination during an incident?

Decontamination during a hazardous materials incident is essential to ensure the safety of all parties involved, including victims, responders, and equipment. In this context, requiring decontamination for all these groups reflects the comprehensive nature of hazardous materials response.

Victims may be contaminated with hazardous substances, either through exposure to spills or through contact with contaminated environments. Decontamination of victims is critical for their safety, as it prevents further absorption of harmful substances and reduces the risk of spreading contamination.

Responders also need thorough decontamination after working in a contaminated area. This process protects their health, ensuring that they do not carry hazardous materials back to their vehicles or homes, which could result in further exposure or harm to themselves and others.

Equipment used during the incident, such as protective gear, tools, or vehicles, must also undergo decontamination. Contaminated equipment poses a risk of spreading hazardous materials and can compromise the safety of future operations. Proper decontamination ensures that all equipment is safe for reuse and does not contribute to secondary contamination.

Thus, the correct answer reflects a holistic approach to decontamination during a hazardous materials incident, wherein all parties must be considered to maintain safety and reduce risk.
