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 ladder’s load rating and of the weight it is supporting, including the weight of any tools or equipment.

Ladders are built from one of three basic materials; wood, fiberglass, and metal (aluminum).  

The environment of your work site is the first factor in choosing the material from which your ladder is constructed. For example, if you are working near sources of electricity, a metal ladder should be rejected since aluminum is an electrical conductor.  Your body can complete an electrical circuit between the electrical power source, the ladder, and then to the ground in the event of a live wire contact incident.  An electrical shock while working from a ladder can trigger a fall or cause your heart to stop leading to serious injury or death.  On the other hand, if there are no electrical power sources in your work area, the aluminum ladder is the lightest weight when compared to fiberglass or wood.  

There are also several kinds of ladders manufactured for a variety of uses.  Again, evaluation of your work environment and knowledge of what ladders are available will allow you to choose the right ladder for the job.  Each of the following considerations addresses safety issues in your work environment: 

  • Will the ladder be resting on an uneven surface?
  • Is the work area crowded with people and/or materials?
  • What obstructions are in the path of the climb?

Next, the proper ladder length must be selected.It is unsafe to use a ladder that is too long or too short.  When using a Step Ladder,for example, standing on the top cap or the step below the top cap is not permitted due to the increased likelihood of losing your balance.  Likewise, when using an Extension Ladder, the top three rungs are not to be used for climbing. A Straight Ladder is too long, for example, if ceiling height prohibits the ladder from being set-up at the proper angle.  Likewise, an Extension Ladder is too long if the ladder extends more than 3 feet beyond the upper support point.  In this case, the portion of the ladder that extends above the upper support point can act like a lever and cause the base of the ladder to move or slide out.  Safety standards require a label on the ladder to indicate the highest standing level.

Next, consider the Duty Rating of the ladder.  This is an indication of the maximum weight capacity the ladder can safely carry.  To figure out the total amount of weight your ladder will be supporting, add:

  • Your Weight; plus
  • The Weight of Your Clothing and Protective Equipment; plus
  • The Weight of Tools and Supplies You Are Carrying; plus
  • The Weight of Tools and Supplies Stored on the Ladder

There are five categories of ladder Duty Ratings:
Type IAA (Extra Heavy Duty)  375 pounds
Type IA (Extra Heavy Duty) 300 pounds
Type I (Heavy Duty) 250 pounds
Type II (Medium Duty) 225 pounds
Type III (Light Duty) 200 pounds                                        No No No

The Duty Rating of your ladder can be found on the specifications label.  Safety standards require a Duty Rating sticker to be placed on the side of every ladder.  Do not assume that a longer ladder has a higher weight capacity.   There is no relationship between ladder length and weight capacity.
