What is the recommended hoseline for pin-in accidents?

In the context of pin-in accidents, the 2½" hoseline is the recommended choice due to its balance of flow capacity and maneuverability. This size hoseline provides sufficient water flow to effectively combat potential fire hazards that may arise during extrication procedures, while still being manageable for firefighters working in often confined and challenging environments typical of vehicle accidents.

The larger diameter allows for a higher volume of water to be delivered quickly if there is a fire situation, which is crucial as it helps protect both the rescuers and victims involved in the accident. This hoseline strikes the right balance; it is robust enough to handle the demands of such incidents without being overly cumbersome, which would hinder mobility and efficiency during rescue operations.

Choosing smaller hoselines like a 1½" may not provide adequate flow in more severe situations, and going for larger sizes like 3" could be excessive and impractical in the confined spaces usually encountered during pin-in rescues. Therefore, the 2½" hoseline is ideally suited for these particular emergencies, ensuring a swift and effective response.
