Which option is not a standard procedure step in hazardous materials response?

• A. Disregard decontamination
• B. Locate and verify the nature of the incident
• C. Refer to the SDS
• D. Evacuate the area

Answer: (A)

In hazardous materials response, following established steps to protect people and contain the hazard is essential. Decontamination is a core part of the response because it removes or reduces hazardous substances from patients, responders, and equipment, preventing secondary exposure and the spread of contamination. Disregarding decontamination would leave responders and anyone connected to the scene at risk and undermine the effectiveness of the whole response.

Locating and verifying the nature of the incident helps you understand what you’re dealing with—whether it’s a chemical, biological, or other hazardous material—so you can apply the correct protective measures. Referring to the Safety Data Sheet provides material-specific information on hazards, required PPE, and decon procedures, guiding actions to stay safe and effective. Evacuating the area protects unexposed individuals and creates the space needed to implement decon, control the scene, and prevent further exposure.

So, the option that involves ignoring decontamination does not fit standard practice, while the other steps are typical, appropriate actions in a hazardous materials response.
