Inspecting Ground Conditions Before Ladder Use Toolbox Talk

Before setting up any ladder, the ground must be inspected to ensure it can safely support both the ladder and the worker. Even the best ladder can become unstable if it is placed on soft, uneven, slippery, or shifting ground. Taking a few moments to assess ground conditions helps prevent slips, tip-overs, and falls.

This toolbox talk reviews how to evaluate ground conditions before ladder use and the steps needed to ensure a stable and secure setup.

Why This Matters

• Unstable ground is a leading cause of ladder movement and falls.
• Proper footing helps keep the ladder secure throughout the task.
• Ground conditions can change due to weather, excavation, or nearby work activities.
• Inspecting the work area helps identify hazards before climbing.
• A stable foundation is essential for safe ladder use.

Common Hazards

• Soft ground, mud, sand, or loose gravel.
• Uneven or sloped surfaces.
• Wet, icy, oily, or otherwise slippery conditions.
• Recently backfilled trenches or excavations.
• Ground weakened by erosion, vibration, or underground voids.
• Debris, cords, hoses, or materials beneath the ladder feet.
• Floor surfaces with holes, cracks, or damaged concrete.
• High winds or weather conditions affecting ladder stability.

Safety Checklist

Before Work Begins

• Inspect the entire work area and select a firm, level, and stable surface.
• Remove debris, loose materials, and other obstructions from the ladder base.
• Check for soft soil, unstable fill, or damaged flooring that could allow the ladder to shift.
• Ensure the ladder feet make full contact with the supporting surface.
• Do not use boxes, bricks, pallets, or other makeshift objects to level the ladder.
• Secure the ladder where practical to prevent movement.
• Consider weather conditions that could affect stability, especially when working outdoors.

During Work

• Monitor ground conditions for changes caused by rain, vibration, excavation, or other site activities.
• Maintain three points of contact while climbing.
• Keep your body centered between the ladder side rails.
• Reposition the ladder if the surface no longer provides stable support.
• Do not continue using a ladder that shifts, rocks, or sinks into the ground.
• Stop work immediately if the supporting surface becomes unsafe.

Crew Talking Points

• Is the selected location firm, level, and capable of supporting the ladder?
• Have recent weather or site activities changed the ground conditions?
• Can the ladder be secured to prevent movement?
• Would another type of access equipment be safer for this location?
• Has everyone inspected the ladder setup before climbing?
• Speak up immediately if you notice unstable ground or a ladder beginning to shift.

Stop Work If

• The ground cannot safely support the ladder.
• The ladder rocks, slips, or sinks during use.
• The ladder feet cannot make stable contact with the supporting surface.
• Changing weather or site conditions create instability.
• Makeshift methods are required to level or stabilize the ladder.
• You are unsure whether the ladder can be used safely.

Final Reminder

A ladder is only as stable as the surface beneath it. Always inspect the ground before setup, choose a firm and level location, secure the ladder whenever practical, and never climb if the supporting surface cannot provide safe, stable footing.
