the wearer. Any snap hooks should be made of materials resistant to sparking on impact. An air hose of 19mm internal diameter with a smooth bore lining. The hose is so constructed that it does not collapse. Where lengths of hose are coupled together, and at the connections to the bellows and harness, sealing washers are used. The hose must be long enough to reach from the open deck to any part of the vessel. However, it will not normally be permitted to provide an air hose of less than 18m, nor required to provide an air hose in excess of 36m. A lifeline of flexible galvanised steel wire covered in plaited rope. The lifeline must be 3m longer than the air hose. Double action foot bellows. The double action ensures that air is supplied to the fire fighter on both the up stoke and down stoke of the bellows. There will be a filter arrangement to prevent foreign bodies being transmitted along the air line. Two signal plates are provided: one screwed to the bellows and one attached to the harness. It is anticipated that communication between the wearer and the bellows operator will be giving short, sharp pulls on the lifeline. For example: 1 pull = more air required 2 pulls = give more slack on lifeline 3 pulls = help me out immediately / come out immediately. All members of the fire fighting parties should be thoroughly familiar with the signals. A safety helmet. This is often part of the fireman’s protective clothing. The entire apparatus should be carefully stowed in a suitably sized container.
