(8) Storage. Store scaffolds in a dry place to prevent the warping or splintering of wood
sections; the rusting of wire cables, tackle blocks, or hoisting machines; or the rotting of fiber ropes.
d. Boatswain's Chair.
(1) The boatswain's chair shown in Figure 4-20 is made to support one man. Use the chair to
paint small areas that cannot be reached by ladders or where it is impractical to erect scaffolds. A
double bowline knot is used to make up the chair. For short periods of time, the chair can be used
without the notched board by inserting your legs through the loops.
Figure 4-20. Boatswain's chair
(2) The boatswains chair with suspending tackle (Figure 4-21) is supported by securing block
and tackle to the building's roof, ceiling joists, or rafters. Before using the chair, ensure that it is
attached securely. You can either raise or lower yourself or be assisted by a person on the ground.
When working alone, the fall line (control) is attached to the suspending tackle (two double blocks) with
a rolling hitch. The fall line allows you to lower yourself. When receiving assistance from the ground,
the fall line should be tied to a tree or a building member that will hold your weight.
