Which piece of equipment is required to perform an emergency drag from a vehicle?

In emergency situations involving vehicle extrications, the aim is to safely and efficiently move an injured person from a vehicle to a safer location while minimizing further injury. While various pieces of equipment can assist in patient transport, the requirement for specifically performing an emergency drag is primarily guided by the urgency and risks involved rather than the availability of a set piece of equipment.

A stretcher is often used for transporting patients securely, but it may not always be necessary or practical in an emergency drag situation. Likewise, a harness can be useful in certain rescue scenarios but is not specifically required for performing an emergency drag. The use of a rescue blanket may assist in protecting or keeping a patient warm during transport, yet it does not inherently provide the necessary support needed for a drag.

Therefore, the statement that "none of these is correct" aligns with the understanding that emergency drags can be executed without these specific pieces of equipment depending on the circumstances, the condition of the patient, and the environment.
