Ladder safety

Ladders come in many sizes and shapes for many specific purposes, as pictured in Figure . They can be made of wood, aluminum, or fiberglass and are designed for either light or industrial use. The two most common types are straight ladders and stepladders. Regardless of the type or construction, be sure the ladder has a label certifying that it complies with specifications of the American National Standards Institute (ANSI) and the Underwriters Laboratories (UL).

More than 30,000 people in the United States are injured each year by falls involving ladders. Most of these accidents occur because people do not follow the basic rules of ladder safety:

  • Select the right ladder for the job.
  • Inspect the ladder.
  • Set the ladder properly and safely. Sample values for different heights are shown in Figure .
  • Climb and descend safely. Climbing too high can also lead to accidents.
  • Work on the ladder safely.
  • Secure the area around the ladder. Cordon off the work area with appropriate markers like the traffic cones shown in Figure or caution tape, as shown in Figure . Lock or block any nearby door that opens inside.
