Portable Ladder Safety

Falls from portable ladders (step, straight, combination and extension) are one of the leading causes of occupational fatalities and injuries.
  • Read and follow all labels/markings on the ladder.
  • Avoid electrical hazards! Look for overhead power lines before handling a ladder. Avoid using a metal ladder near power lines or exposed energized electrical equipment.
  • Always inspect the ladder prior to using it. If the ladder is damaged, it must be removed from service and tagged until repaired or discarded.
  • Always maintain a 3-point (two hands and a foot, or two feet and a hand) contact on the ladder when climbing. Keep your body near the middle of the step and always face the ladder while climbing (see diagram).
  • Only use ladders and appropriate accessories (ladder levelers, jacks or hooks) for their designed purposes.
  • Ladders must be free of any slippery material on the rungs, steps or feet.
  • Do not use a self-supporting ladder (e.g., step ladder) as a single ladder or in a partially closed position.
  • Do not use the top step/rung of a ladder as a step/rung unless it was designed for that purpose.
  • Use a ladder only on a stable and level surface, unless it has been secured (top or bottom) to prevent displacement.
  • Do not place a ladder on boxes, barrels or other unstable bases to obtain additional height.
  • Do not move or shift a ladder while a person or equipment is on the ladder.
  • An extension or straight ladder used to access an elevated surface must extend at least 3 feet above the point of support (see diagram). Do not stand on the three top rungs of a straight, single or extension ladder.
  • The proper angle for setting up a ladder is to place its base a quarter of the working length of the ladder from the wall or other vertical surface (see diagram).
  • A ladder placed in any location where it can be displaced by other work activities must be secured to prevent displacement or a barricade must be erected to keep traffic away from the ladder.
  • Be sure that all locks on an extension ladder are properly engaged.
  • Do not exceed the maximum load rating of a ladder. Be aware of the ladders load rating and of the weight it is supporting, including the weight of any tools or equipment.
