What is required for safety at the scene of an incident?

Wearing a reflective vest is essential for safety at the scene of an incident because it significantly enhances visibility, especially in low-light conditions or during adverse weather. This visibility is crucial for ensuring that all personnel involved, including first responders and motorists, can see each other from a distance. A reflective vest helps to define the area as active and minimizes the risk of accidents, making it easier for passing vehicles to recognize that there is a situation that requires caution.

While warning oncoming traffic is important, it is not as effective as wearing a reflective vest since the vest provides a continuous visibility measure for anyone approaching the scene. Jacking up an involved vehicle is a task that should be executed carefully and primarily concerns mechanical work rather than safety during initial response. Setting tow truck lights on high beam might initially seem beneficial for visibility, but it can actually create glare, making it harder for drivers to see and react appropriately. Thus, wearing a reflective vest is the best practice for ensuring safety in these situations.
