Which of the following is NOT an example of improvised edge padding?

Improvised edge padding is crucial in technical rescue operations to protect rope and equipment from sharp edges that could cause damage during a rescue. The correct choice highlights that safety helmets are not typically used for this purpose.

Bunker gear, fire hose, and rope bags can all provide effective padding around edges. Bunker gear, which is made of thick, durable materials, can be wrapped around or placed against sharp edges to cushion the rope. Fire hose, with its robust construction, can also be cut and shaped to protect edges effectively. Rope bags can serve a similar function, as their material is generally designed to avoid damage to the rope they hold, thus providing a layer of protection.

In contrast, safety helmets are designed to protect the head from falling objects or impacts, focusing on personal protection rather than providing edge padding for equipment. While they are essential for safety in hazardous environments, they do not serve the same function as the other listed items when it comes to protecting ropes against sharp surfaces.
