What is the function of a rescue blanket during vehicle extrication?

The function of a rescue blanket during vehicle extrication is primarily to protect and shield the victims from debris and adverse weather elements. In rescue scenarios, particularly those involving accidents, victims may be exposed to various hazards, including flying debris from an unstable vehicle, rain, cold, or extreme heat. The rescue blanket serves as an effective barrier, helping to maintain body temperature, protect against environmental dangers, and provide a sense of comfort and security to the victims while they await further medical assistance.

Using a blanket in this way enhances the safety and care of the victims during a critical time, allowing emergency personnel to focus on extrication without compromising the victims' protection. While other options might suggest potential uses for a blanket, they do not align with the primary purpose established within the context of vehicle rescue operations.
