Figure 1-6. Ladder safety shoes
Use only portable ladders that can be readily carried and placed by two men. Use the
correct length of ladder; never splice ladders to form a longer ladder.
Pretest all ladders and scaffolds before use by placing them horizontally, with blocks
under ends, and bouncing in the center or walking along the ladder or scaffold.
Use stepladders that are 10 feet or less in height. Avoid using stepladders as a
straight ladder or standing on the top platform of ladders.
Rope off all doorways in front of the ladder and place warning signs. Use hand lines
to raise or lower tools and materials. Avoid reaching out from the ladder in any
direction; instead, move the ladder as the work requires.
Avoid using metal ladders in areas where contact with electric power lines is possible.
Use extension ladders that have a minimum overlap of 15 percent for each section
(Figure 1-7, page 1-10).
