Extension Ladder Setup and Use Toolbox Talk

Extension ladders are used on almost every construction site, but they are also involved in many fall injuries. A ladder that is set up incorrectly, placed on unstable ground, or used beyond its limits can shift, slide, or tip over without warning. Even a small mistake during setup can turn a routine task into a serious fall.

This toolbox talk focuses on proper extension ladder setup and safe work practices while climbing and working from ladders. Taking a few extra minutes to position the ladder correctly and inspect it before use can prevent falls and keep the crew working safely.

Why This Matters

• Falls from ladders are one of the most common construction injuries
• Improper ladder angles increase the risk of the ladder sliding out or tipping backward
• Unstable ground or uneven surfaces can cause ladder movement
• Overreaching while on a ladder can shift the center of balance
• Damaged ladders can fail under normal use

Common Hazards

• Ladders set at the wrong angle or not fully extended
• Ladder feet placed on mud, gravel, or loose material
• Ladders not tied off or secured at the top
• Workers carrying tools while climbing
• Standing on the top rungs or beyond the safe working height
• Wind or passing equipment causing ladder movement

Safety Checklist

Before Work Begins

• Inspect the ladder for cracks, bent rails, loose rungs, or damaged feet
• Set the ladder using the 4-to-1 rule for proper angle
• Place the ladder on firm, level ground
• Extend the ladder at least three feet above the landing surface
• Secure the ladder at the top or have someone stabilize it if needed

During Work

• Maintain three points of contact while climbing
• Face the ladder when going up or down
• Keep your belt buckle between the ladder rails
• Use tool belts or hoist tools instead of carrying them while climbing
• Do not move or shift the ladder while someone is on it

Crew Talking Points

• Where are extension ladders commonly used on this jobsite?
• Who checks ladders for damage before they are used?
• What should you do if the ground is uneven where the ladder needs to be placed?
• How do we secure ladders when accessing roofs or elevated platforms?
• What signs indicate a ladder should be taken out of service?
• Does anyone have questions or concerns about ladder use on this site?

Stop Work If

• The ladder is damaged or missing safety feet
• The ladder cannot be placed on stable ground
• The ladder is not tall enough to safely reach the work area
• Wind or site conditions make ladder use unsafe
• Workers are climbing with materials or tools that limit safe movement

Final Reminder

A ladder may seem like simple equipment, but it must be set up correctly every time. Take the time to inspect it, position it properly, and climb safely to prevent falls.
