the best ladder for the job
Ladders are available
in three basic materials and five ladder ratings, as follows:
are lightweight, strong and very affordable. They resist corrosion when
stored outside, but are not recommended for use around electrical lines.
Fiberglass Ladders are also lightweight and very strong. They are
a bit more costly than aluminum ladders and are better suited for work
around electrical lines, since they are non-conductive.
Wood Ladders are electrically non-conductive (when dry and clean)
and are the least expensive form of stepladder. Wooden extension ladders
can be very heavy and difficult to control. Wood ladders will rot if left
out in the weather.
Today's ladders are rated for load capacity, as follows:
- TYPE III
ladders are Light Duty Ladders, rated to hold up to 200 lbs.
- TYPE II
ladders are Medium Duty Ladders, rated to hold up to 225 lbs.
- TYPE I
ladders are Heavy Duty Ladders, rated to hold up to 250 lbs.
- TYPE IA
ladders are Extra Heavy Duty Ladders, rated to hold up to 300
- TYPE IAA
ladders are Special Duty Ladders, rated to hold up to 375 lbs.
and maintaining ladders
Between jobs, ladders
should be stored horizontally on supports to prevent sagging. This is
especially true for wooden ladders.
- Before using a
ladder, check to be sure all fastenings are tight and all movable parts
are lightly oiled for ease of operation.
- Check to be sure
rungs and steps are clean and free of grease and dirt.
- If the rubber
feet on an extension ladder are missing, replace them.
- If your extension
ladder is equipped with a raising rope, be sure it is in good condition
and that all pulleys are functioning properly.
