(2) Raising and placing a ladder. To raise a ladder (Figure 4-3), place the ladder base against

the foundation of the building, raise the top end of the ladder, and walk under it toward the building. As

soon as the ladder is perpendicular, pull the ladder bottom out from the building to a distance of one-

fourth of the working length of the ladder (Figure 4-4). If it is necessary for you to get on top of a

building, the ladder must extend at least 30 inches above the eaves. The ideal ladder angle is about 70

degrees, this is shown on the far right of Figure 4-5, page 4-4. At this angle, the feet of a 28-foot ladder

touches the ground about 72 inches from the building. The ratio is 1 foot away from the wall for every 4

feet of the ladder's height.
