Rescue of a casualty
Where a breathing apparatus team plans to exit with a casualty, it is essential that a gauge reading is taken and a calculation made on the air required to leave the incident unless they are already close to an exit. If there is an insufficient air supply to exit with the casualty, the team should request additional assistance from the BA entry control operative.
On exiting the risk area, further gauge readings should be taken when reaching familiar landmarks. By referring to earlier calculations, team members will be able to determine whether they can leave the incident with the casualty or progress as far as possible before having to leave the casualty with another BA team. The team must remain in communication with the BA entry control operative so that appropriate support and additional risk control measures can be introduced where necessary.
