Before turning off the vehicle, what should you do?

Rolling down the windows and unlocking the doors is the appropriate step to take before turning off the vehicle, especially in an emergency response situation. This action provides a way for ventilation and ensures that the vehicle is accessible when needed. In the context of emergency services, it allows for a quick exit should the situation demand it, particularly if there are concerns about safety or a quick departure from the area.

Proper ventilation is critical to prevent the buildup of harmful fumes, especially if the vehicle has been idling for a while. Additionally, by unlocking the doors, it ensures that team members can exit the vehicle quickly if necessary. This proactive measure enhances safety and ensures readiness to respond rapidly if the situation changes.

In emergency scenarios, it's vital to prioritize accessibility and safety over other actions that may not have the same immediate impact.
