Ladder safety starts before your first step. The useful question is whether this particular ladder, in this particular location, fits the work you are about to do. A sound ladder can still become unsafe when a doorway opens into it, tools overload it, or the task requires a reach that takes you outside its rails.
Use these ladder safety checks alongside your employer’s training and the manufacturer’s instructions. If you are new to the project, begin with your first day on a jobsite so you know who can resolve an access problem before work starts.
A useful check ends with a decision: use the ladder as planned, change the setup, or stop until the problem is resolved. An unanswered question is a reason to pause and get help.
Choose the ladder around the task
Describe the job before choosing equipment: where you must reach, how long you expect to work, what you need to handle, and how you will get there. Tell your supervisor if the task involves substantial sideways force, awkward materials, or frequent repositioning. Ask whether a suitable platform or another access method would make the work easier to control.
For example, replacing fixtures along a corridor creates a different access problem from making one brief inspection. Discuss the sequence with the crew so the chosen equipment supports the whole job, including supplying materials and moving between locations.
Check height, configuration, and total load
A ladder’s overall length, permitted standing level, and duty rating describe different things. Select a size that reaches the job without standing above its permitted level. Follow the labels for the exact model and configuration; a multiposition ladder has instructions for each approved setup.
Include your body weight, clothing, tools, and materials when checking capacity. OSHA’s stepladder guidance explains why the load includes everything carried. For a conventional stepladder, open it fully, engage its spreaders, and stay off the top cap and top step. Never gain extra height by standing the ladder on boxes.
When a label is unreadable
Do not guess at the rating or approved configuration. Set the ladder aside and ask your supervisor to confirm its identification and instructions. Equipment that looks similar can have different limits. Include bulky clothing and other equipment discussed in our PPE fit and selection guide when planning the climb.
Inspect before anyone climbs
Look over the ladder where you can see its full length. Work systematically from the feet upward rather than checking only the first few steps. The OSHA portable ladder QuickCard recommends inspection before use and removing damaged ladders from service.
- Rails and steps: Look for cracks, bends, splits, corrosion, loose connections, or missing parts.
- Feet: Check for damage, contamination, and missing components that could affect contact with the ground.
- Locks and hardware: Check spreaders, hinges, and extension locks according to the manufacturer’s instructions.
- Climbing surfaces: Look for mud, grease, wet material, or anything else that could make a hand or boot slip.
A defective ladder needs a clear outcome: remove it from use, identify it as defective, and report it. Follow the site’s tagging and storage procedure so another person cannot mistake it for available equipment. Leave repair decisions to the employer’s authorized process; do not straighten, tape, or modify a damaged component to finish the job.
Your pre-use check does not replace periodic inspection by a competent person or inspection after an event that could affect safe use. Report a ladder that fell during unloading, even when damage is not obvious.
Check the ground, support, and landing
Walk around the planned position. Clear the top and bottom access areas, check the surface, and identify doors, deliveries, and nearby work. Use the approved securing or barricading arrangements where activity could displace the ladder. If equipment operates nearby, coordinate the area using the principles in working near heavy equipment before setting up.
Understand the extension ladder setup
For a manufactured straight or extension ladder, the familiar 4:1 setup means a horizontal base distance approximately one-quarter of its working length. Working length is measured along the ladder from its foot to the top support. It is not simply the ladder’s advertised size. Check the specific manufacturer’s setup instructions.
Under OSHA’s construction ladder standard, a portable ladder used to reach an upper landing must extend its side rails at least 3 feet above that landing. If its length prevents that extension, the alternative requires securing the top to a rigid support that will not deflect and providing a grasping device, such as a grabrail. Deflection under load must not cause the ladder to slip off its support. Ask the responsible supervisor to resolve the access arrangement before climbing.
Plan the climb and the work position
Face the ladder and maintain three points of contact while climbing: two hands and one foot, or two feet and one hand. Plan how tools and materials will reach the work area without occupying the hands needed for climbing or upsetting your balance. A tool belt must still fit the task and remain within the ladder’s load rating.
Keep your body centered between the rails. Come down and reposition when the work moves beyond a comfortable reach. Do not move, shift, or extend a ladder while someone is on it. OSHA’s stairways and ladders guide also addresses clear access, secure placement, and loads that could cause a climber to lose balance.
Look beyond the ladder itself
Identify overhead lines and exposed electrical equipment before carrying or positioning a ladder. Where the worker or ladder could contact exposed energized equipment, nonconductive side rails are required. That does not make approaching electrical hazards safe; have the hazard and necessary controls addressed before proceeding.
Consider what will happen if the delivery scheduled for later arrives early. Tell the supervisor if the ladder position blocks the only practical access route. A workable arrangement should allow other crews to do their jobs without stepping around the ladder or moving it without your knowledge.
Plan for the moment a tool is missing or the task changes. Come down to discuss the next step instead of improvising from the ladder. For example, a replacement fitting that needs heavier equipment or a different working position should prompt a fresh conversation about access. The original setup was chosen for the original task.
Make the check part of the handover
Before starting, explain any uncertainty rather than carrying it onto the ladder. OSHA’s ladder training requirements cover hazard recognition, correct use and placement, capacity, and retraining when necessary. Ask for a demonstration if a configuration is unfamiliar.
Add unresolved ladder issues to your daily jobsite safety checks with a clear location and responsible person. Before a coworker takes over, explain the setup and any restrictions. An inspection becomes useful when the next person understands what was checked and what still needs attention.
