Log Rolling

An effective technique for transferring a casualty from the floor to a long board.
You need a minimum of five people - 3 for the roll, one for supporting the head, and 1 for sliding the board underneath the casualty.
The roll works thusly - the person maintaining central alignment is in control, and commands when it is time to move the casualty. The people doing the rolling kneel to one side of the casualty, lean over, cross over hands with each other, grab a bit of clothing (perferably) and on the count of the person at the top, roll the casualty towards them. The person with the long board slides it against the back of the casualty, and on the count of the 'head' person again, the casualty is then rolled back onto the board and strapped in securely, ready for transportation.
Its good for spinal casualties, with the aim to keep the spine and neck in exact alignment and minimise any movement which could result in more damage of the spine.
