STEP LADDERS:
What should you do when using a stepladder?
Check the load rating that is marked on the stepladder. The rating should cover the person's weight and
the weight of tools that will be used.
Use a stepladder that is about 1 m (3 ft) shorter than the highest point you have to reach. This gives a
wider, more stable base and places shelf at a convenient working height.
Do not use a ladder that has cracks, lose or corroded rivets, defective braces, or parts (including the slip
resistant feet) that are in poor condition. Make sure it is free of grease or oil or other slippery
substances.
Open the stepladder spreaders and shelf fully and lock the braces.
Check stability. Ensure that all ladder feet are on a firm, level and non-slippery surface.
Place a stepladder at right angles to the work, with either the front or back of the steps facing the work.
Keep the stepladder close to the work.
Avoid pushing or pulling stepladders from the side. Repeated sideways movement can make ladders
wobbly since they are weaker or less stable in those directions.
Face the stepladder when climbing up or down. Keep your body centered between side rails. You have
climbed too high if your knees are above top of the stepladder or if you cannot maintain a handhold on
the ladder.
Maintain a firm grip. Use both hands when climbing.
What are step ladder ratings, and is there a maximum length for a step ladder?
The Canadian Standards Association (CSA) Standard Z11-12 recommends different lengths for different rating
(or grades) of step ladders.
