If you are in your car and learn of an accident involving a volatile toxic substance ahead of you, what should you do?

When faced with a situation involving an accident with a volatile toxic substance, the most appropriate action is to follow instructions and remain clear of the release plume. The release plume is the area where the toxic substance is dispersed, and it can be hazardous to health. By staying clear of this area, you are protecting yourself from possible exposure to harmful chemicals.

Remaining in your vehicle can also provide a temporary buffer from potential contaminants, as vehicles can offer some protection from airborne substances. It's vital to stay informed through emergency services or local news updates to understand which way the plume is moving and how to keep yourself safe.

Turning off the car and exiting immediately may expose you to the toxic substance directly, which poses a health risk. Driving around the area quickly could also expose you to the plume, especially if wind conditions change. Notifying emergency services is important, but following established safety protocols takes precedence to ensure you are not in harm's way while doing so.
