Stretcher access?

Some construction sites require stairs of 1 metre wide to allow for an injured person to be carried down on a stretcher. Fact is that if that injured person turns out to be heavy-built, carrying this person down a flight of stairs will become a hazard in itself.

In any event, when a person is injured on a roof and is not capable of moving him/herself, simply dial 000. The operator will ask the relevant questions to determine what is required.

In cases whereby a person is to be lifted off the roof, the fire brigade might send out the High Angle Rescue Team (HART) to assist with the safe transport off the roof.
