Ladders - Step

• 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.

The Canadian Standards Association (CSA) Standard Z11-12 recommends different lengths for different rating (or grades) of step ladders.

• Do not overreach. Move a stepladder when needed.
• Do not "shift" or "walk" a stepladder when standing on it.
• Do not stand, climb, or sit on the stepladder top or pail shelf.
• Do not stand on or above the top two rungs or steps of the stepladder.
• Do not overload. Stepladders are meant for one person.
• Do not use a stepladder as a brace or as a support for a work platform or plank.

• Do not climb a stepladder that is leaning against a wall. Use a straight ladder instead.
• Do not use stepladders on slippery surfaces
• Do not use stepladders on soft ground where one leg may sink farther into the ground than others.
• Do not place stepladders on boxes, barrels, unstable bases, or on scaffolds to gain additional height.
• Do not climb the back of a stepladder.
• Do not push or pull stepladders sideways.
• Do not use ladders in passageways, doorways, driveways or other locations where a person or vehicle can hit it. Set up suitable barriers or lock doors shut.
