Which equipment is essential for securing a scene after a vehicle accident?

Traffic cones are essential for securing a scene after a vehicle accident as they serve as a visual warning to approaching motorists about the hazard ahead. Placing cones strategically can help direct traffic away from the accident site, protecting both the victims and emergency responders from potential secondary accidents or injuries. This is crucial for maintaining safety around the scene and ensuring that emergency personnel can work effectively without interference from vehicles.

While other equipment like fire hoses, cutting tools, and medical kits are important for emergency responses, they do not serve the primary function of securing the scene and managing traffic flow, which is a critical first step in emergency management after a vehicle accident.
