(4) Carrying a ladder. When carrying a ladder, use your arms to stabilize it then carry the
ladder horizontally at waist-height (Figure 4-7). A long ladder may require two people to carry it.

(5) Using extension planking and ladder jacks. Two ladders may be adapted to hold a
scaffold board or extension planking by using one steel ladder jack (Figure 4-8) for each ladder. Mount
the jack on the front or back side of the ladder. By placing the ladder jacks between the ladder and the
building being painted, you can work closer to the wall. Extension planking (Figure 4-9, page 4-6) is
made of well-seasoned material that is straight-grained and free of any knots or defects. Extension
planking is available in various sizes and is constructed so that its length is adjustable. As shown in
Table 4-1, page 4-6, the size of the lumber used for planking depends on the scaffold span. A scaffold
board made of lumber that is straight-grained and free of knots or any other defects may be used in place
of an extension planking.
