What is the proper sequence of actions when responding to a hazmat incident at the scene?

• A. Accelerate to the next exit to avoid exposure.
• B. Turn off ignition and proceed to a nearby service center without reporting.
• C. Call the shipper only and wait for instructions.
• D. Stop safely, isolate the area, notify authorities, secure the site, consult the ERG, and follow responders' directions.

Answer: (D)

When a hazmat incident occurs, the best approach is a safety-first sequence that starts with stopping and containing the situation, then bringing in proper guidance and responders. Stop safely so you’re not moving toward the hazard or through contaminated areas. Isolate the area to prevent exposure and keep others from entering a danger zone. Notify authorities so trained responders can mobilize and manage the scene. Secure the site to maintain control, prevent unauthorized access, and preserve evidence and conditions for responders. Consult the Emergency Response Guide (ERG) to identify the material involved and obtain initial protective actions. Finally, follow the directions of the responders who are trained to manage the specific substance and evolving conditions on scene. This coordinated approach reduces risk, enables proper assessment, and ensures actions align with established safety procedures.
