If you encounter a gasoline spill on the highway, what is the appropriate immediate action to take?

When dealing with a gasoline spill on the highway, the appropriate immediate action is to contain the spill. Containment is crucial because it helps prevent the gasoline from spreading further, which can minimize the risk of fire, explosion, and environmental contamination. Containing the spill can involve using absorbent materials, barriers, or other methods to restrict the flow of gasoline, thereby making the area safer for both responders and the public.

While evacuating the area or calling emergency services may also be necessary actions, the priority is to manage and reduce the immediate hazard posed by the spill. It is critical to contain the hazard first to ensure that emergency services can act effectively without exposure to a growing risk. Trying to clean it up yourself is not advisable due to the volatile nature of gasoline, the potential safety risks involved, and the expertise required for proper cleanup and disposal. Thus, focusing on containment is the best course of action in this scenario.
