Extension Ladder Safety: A Brief Guide

Working at heights poses serious risks, especially when proper safety precautions are not taken. Extension ladders can provide safe and secure access when used correctly, but they are also involved in many preventable accidents each year. Understanding how to properly select, inspect, set up, and climb extension ladders is crucial for avoiding ladder-related injuries. This comprehensive guide covers everything you need to know about extension ladder safety.

Introduction

Falls from ladders are alarmingly common. According to the Ladder Safety Institute, over 500,000 people visit emergency rooms and over 300 people die from ladder-related accidents in the U.S. every year. Many of these accidents occur while using extension ladders incorrectly or using faulty or inappropriate equipment.

Extension ladders are designed to safely support a user at working heights. However, they require proper selection, maintenance, setup, and use. Taking the time to learn extension ladder safety pays dividends through preventing serious or fatal falls. Critical safety knowledge like maintaining three points of contact, selecting ladders rated for the intended use, and correctly angling ladders should all become second nature.

With training and safe equipment, ladders can be an effective and secure choice for working at heights. This guide covers the essential information you need to make your next climb a safe one.

Choosing the Right Extension Ladder

Not all extension ladders are created equal. The first step in safely using an extension ladder is selecting the right ladder for the intended purpose. Here are key factors to consider:

Height – The ladder must extend high enough to reach the work area without overextending. Leaving at least 3 feet of overlap with the roof or surface is ideal.

Weight capacity – The ladder’s duty rating must exceed the total load. This includes the user’s weight plus tools and materials.

Material – For electrical work, use a nonconductive fiberglass ladder. Aluminum ladders conduct electricity and should only be used when no contact with wires is expected.

Duty rating – The duty rating reflects the maximum safe load capacity of the ladder. For example, a ladder rated “Type IA 300lbs Duty Rating” can safely support 300lbs. Use a ladder with a duty rating at least four times the expected total load.

Slip resistance – Ladder rungs, steps, and feet should have slip-resistant surfaces.

When selecting your extension ladder, carefully check the specifications for height, weight capacity, material, duty rating, and slip resistance. Using a ladder too short or weak for the intended use can have catastrophic results.

Inspecting Your Extension Ladder

Before hauling out and climbing any ladder, a thorough inspection is a must. Check the ladder carefully before each use for any signs of damage, wear, loose rungs or bolts, or instability. Here are key inspection points:

Rungs/steps – Ensure all rungs are straight, securely fastened, and free of grease, oil, or dirt.
Feet – Check feet for deep grooves and slip resistance. Also check leveling pads or spikes for damage.
Rails – Inspect rails for any denting, cracks, corrosion, or twisting. Rails must be straight and true.
Locks, pulleys, ropes – Test all moving parts operate smoothly with no binding or sticking.
Labels – Check duty rating label remains readable and affixed to the ladder.
Accessories – Inspect any levelers, stabilizers, pole straps, or other accessories for damage.

Even minor damage like splinters or twisting can compromise the ladder’s ability to support weight safely. When in doubt, take the ladder out of service.

Proper Extension Ladder Setup

With the right undamaged ladder selected, proper setup is critical for safety and stability. Follow these steps:

Place the ladder on a firm, stable, and level surface. Avoid setting ladders on loose or uneven ground.
Position the ladder base a quarter of the working height away from the structure. For example, if the ladder extends 20 feet, place the base 5 feet from the building.
Extend the ladder to the desired height with at least 3 feet overlapping the roof or surface. Raise by pulling the rope, not the rungs.
Level the ladder by adjusting the extendable legs or using leveling accessories. Recheck for level after extending.
Securely tie or fasten the top of the ladder to prevent shifting or slippage. Use anchor brackets designed for this purpose.
Firmly secure the ladder feet to the ground using stakes, cleats, pads, or other anti-slip surfaces.

Proper ladder angle, overlap, and securing the top and bottom are critical for stability. Always double check for secure footing before climbing.

Climbing and Working Safely on Extension Ladders

Once your extension ladder is properly set up, you must climb, work on, and descend the ladder safely. Follow these tips:

Maintain three points of contact – Keep two hands and one foot or two feet and one hand on the ladder at all times.
Face the ladder and grip rungs, not rails – Look straight at the ladder while climbing and grip rungs or steps securely.
Wear slip-resistant shoes – Shoes with slip-resistant soles minimize the risk of slipping.
Avoid carrying items in hands – Keep hands free for gripping the ladder. Instead, use pockets, tool belts, or hoists.
Don’t overextend or lean sideways – Keep your belt buckle between the ladder rails and do not lean or reach too far to the side.
Work below the top 3 rungs – The top section can become unstable if weighted at the very top.
Take materials up after climbing – Climb up and anchor yourself before hauling up heavy objects. Use pulleys when possible.
Descend slowly with 3 points of contact – Climb down cautiously and never slide down or rush.

By following safe climbing techniques and avoiding overextension, you can work from extension ladders securely. Use accessories like tool belts and pulleys when needed to keep hands free during the climb.

Ladder Safety Equipment and Accessories

While a basic ladder may be sufficient for straightforward jobs, certain accessories can significantly improve safety and stability. Consider incorporating equipment like:

Ladder levelers – Attach to the bottom feet to level the ladder on uneven surfaces.
Ladder stabilizers – Provide a wider, more stable base of support. Often V-shaped.
Ladder extensions – Used to “walk” taller ladders away from the structure.
Anchor brackets – Secure the ladder top to the roof, gutter, or overhang.
Ladder stand-offs – Keep the ladder rails off the gutter or roof parapet.
Temporary guardrails – Prevent falls from the sides for extended work.
Tool holders – Attach pouches and holsters to the rails to keep hands free.
Ladder hoists – Manual or electric pulleys that lift materials up the ladder.

Taking advantage of purpose-built safety accessories minimizes injury risks inherent in working on extension ladders at height.

Ladder Safety Training and Resources

Given the dangers posed by improper ladder use, formal safety training is highly recommended. Many worksites require training for any employees using ladders. Free online training is also available, such as ladder safety tutorials offered by the American Ladder Institute.

Beyond training, staying current on evolving ladder safety best practices and regulations is important. Helpful resources include:

Occupational Health and Safety Administration – OSHA Fact Sheet: Safe Use of Extension Ladders
National Institute for Occupational Safety and Health – NIOSH Ladder Safety
American Ladder Institute – Ladder Safety Training Videos
Ladder Association – UK-based ladder safety organization offering advice

With the right knowledge, gear, and training, extension ladders can be used safely by professionals and do-it-yourselfers alike. This guide covers the essentials but further study through formal training and staying informed is key for staying safe. Work smart, choose equipment suitable to the task, inspect thoroughly, and climb with care.
