household-grade ladders, which can be unsafe.
although fiberglass ladders are more expensive than those made from
wood or aluminum, most pros prefer them because they are sturdy and
nonconductive. fiberglass ladders are lighter than wood but heavier
than aluminum. Wood stepladders are OK for indoor use, but wood
ladders used outside can deteriorate quickly. aluminum ladders are a
reasonable compromise in price and weight but are the most electrically
conductive of the three. note: all ladder materials can conduct elec-
tricity if they’re dirty or wet.
safe working lengths of ladders are always less than their nominal
lengths. When using an 8-ft. stepladder, for example, go no higher
than 6 ft., and never stand on the top step—which usually has a label
stating, “this is not a step.” likewise, a 32-ft. extension ladder is only
26 ft. to 28 ft. long when extended. ladder sections overlap about
one-quarter, and a ladder leaning against a building should be set
away from the wall about one-quarter of the ladder’s extended length.
ladders must be solidly footed to be safe, especially extension
ladders. after setting up the ladder so that its sides are as plumb as
possible, stand on the bottom rungs to seat the feet. adjustable leg
levelers, as shown, are available for leveling ladders on slopes. if you’re
at all unsure about the ladder’s footing, stake its bottom to prevent it
from creeping.
finally, as you work, always keep your hips within the ladder’s sides.
