Ladder Safety at Work: Common Mistakes and How to Avoid Serious Injuries

Ladders look simple. Anyone can climb one, right? But unsafe ladder use is actually one of the most common causes of falls from height at work. Ladder accidents happen everywhere — construction sites, maintenance teams, warehouses, factories, healthcare facilities, logistics hubs, oil and gas operations, cleaning crews, and electrical work.

Ladder safety at work is not just about climbing carefully; it is about choosing the right ladder, inspecting it, setting it up correctly, and using it only when the task is suitable. A single overlooked step can turn a routine task into a serious injury.

Workers and supervisors who regularly perform height-related tasks can strengthen their knowledge through the Working at Height Safety course.

What is ladder safety at work? Ladder safety at work means selecting, inspecting, positioning, securing, climbing, and using ladders in a way that prevents falls, slips, overreaching, electrical contact, and serious workplace injuries.

Why Ladder Safety Matters in the Workplace

Falls from ladders are rarely minor. They can cause fractures, head injuries, spinal injuries, long-term disability, lost working days, legal claims, and enforcement action against employers who fail to manage the risk properly.

For global safety teams, resources like OSHA ladder safety standards, HSE guidance, CCOHS ladder resources, and NIOSH fall-prevention tools are essential references. NIOSH's ladder safety page states that in 2020 there were 161 workplace fatalities from ladders and 22,710 workplace ladder injuries in the United States — numbers that show why ladder fall prevention remains a serious occupational safety issue.

Building a culture around ladder injury prevention, ladder accident prevention, and broader workplace fall prevention isn't optional. It's a core part of occupational injury prevention programs across every industry that uses ladders.

Common Ladder Safety Mistakes That Cause Serious Injuries

1. Choosing the Wrong Ladder for the Job

Workers often grab whatever ladder is closest, even if it's too short, too weak, made of the wrong material, or simply unsuitable for the task. Proper ladder selection means thinking about ladder height selection, ladder type selection, and ladder load rating or duty rating before you climb.

For example, using a metal ladder near electrical work increases the risk of electric shock. For electrical tasks, non-conductive ladders such as fibreglass are generally safer when appropriate.

2. Skipping the Ladder Inspection

A ladder inspection checklist should be second nature before every use. Look for cracked rails, bent rungs, damaged feet, loose locking devices, corrosion, oil, mud, missing labels, or unstable spreaders.

Never use a damaged ladder. Tag it out and remove it from service immediately.

3. Poor Ladder Setup and Positioning

Unstable ground, slippery surfaces, doorways, traffic areas, and uneven floors are all common causes of ladder accidents. Getting proper ladder setup right — including ladder positioning safety and ladder stability safety — is critical.

For extension ladders, remember the 4 to 1 ladder rule: the base should sit about 1 foot away from the wall for every 4 feet of ladder height. OSHA's ladder safety standards for construction  also highlights serious fall and electrocution risks when extension ladders are set up incorrectly.

4. Overreaching While Working

Ladder overreaching shifts your centre of gravity and can cause the ladder to slip or tip without warning. The practical rule is simple: keep your belt buckle or body centre between the ladder's side rails at all times, and reposition the ladder instead of stretching further.

5. Losing Three Points of Contact

Safe ladder climbing depends on maintaining three points of contact — two hands and one foot, or two feet and one hand — throughout the climb. This single habit is one of the most effective ways to prevent slips and falls during ladder climbing.

Ladder Hazards at Work: What Safety Teams Should Assess

For HSE officers and supervisors, a practical hazard review should cover:

A proper ladder risk assessment should be completed before the task begins — especially for construction, maintenance, roof access, electrical work, and warehouse operations. Taking a few extra minutes to assess these factors can be the difference between a routine job and a serious incident.

Safe Ladder Use: Practical Guidelines Workers Should Follow

Knowing how to use a ladder safely comes down to a few consistent habits, applied every single time — not just when someone's watching.

Before Using a Ladder

• Choose the right ladder for the job
• Check the ladder load rating and weight capacity
• Inspect the ladder before use
• Place it on firm, level ground
• Keep the area clear of doors, vehicles, and obstructions
• Secure the ladder where needed
• Avoid using ladders in unsafe weather or poor lighting

While Climbing or Working

• Face the ladder while climbing
• Maintain three points of contact
• Do not carry heavy tools by hand while climbing
• Do not stand on the top cap of a stepladder
• Do not overreach
• Do not move or shift a ladder while someone is on it

The HSE's safe-use guidance is useful for explaining when ladders are suitable and when alternative equipment should be considered.

Ladder Inspection Checklist: What to Check Before Work Starts

How do you inspect a ladder before use? Inspect the ladder's side rails, rungs, steps, feet, locking devices, spreaders, labels, cleanliness, and overall stability. If anything is cracked, bent, loose, missing, slippery, or damaged, do not use the ladder.

Quick Ladder Inspection Checklist

• Side rails: no cracks, bends, dents, or splits
• Rungs/steps: clean, dry, secure, and not slippery
• Feet: anti-slip feet present and in good condition
• Locks/spreaders: working correctly
• Labels: visible load rating and safety information
• Surface condition: no oil, mud, grease, or wet material
• Damage control: defective ladders tagged out immediately

CCOHS provides ladder safety fact sheets covering selection, inspection, climbing, securing, storage, and handling.

Ladder Safety Training: Who Needs It and Why?

Ladder safety training isn't just for new hires — it's important for workers, supervisors, contractors, and HSE teams alike. Good training covers ladder hazards, ladder selection, ladder inspection, safe climbing, ladder setup, securing methods, emergency response, and fall prevention.

Whether you're looking into ladder safety training, a ladder safety course, ladder safety certification, or a ladder safety certificate, the goal is the same: reducing preventable injuries. This also extends to more specific areas like ladder inspection training, portable ladder training, extension ladder training, step ladder training, working at height training, and fall prevention training.

A structured Working at Height Safety course can help workers and supervisors understand ladder risks as part of wider height-safety control measures.

This is especially useful for workers applying for safety-related jobs in the USA, Canada, GCC, UK, and EU; construction; oil and gas; maintenance; logistics; manufacturing; and industrial sectors.

Ladder Safety Do's and Don'ts

Preventing Ladder Injuries Starts Before the Climb

Most ladder accidents are preventable. Serious injuries often happen because of small mistakes: using the wrong ladder, skipping inspection, setting up on unstable ground, overreaching, or rushing the job.

For workers, supervisors, and safety professionals, ladder safety should be part of a wider working-at-height culture. Build stronger prevention skills with our Working at Height Safety course and learn how to reduce fall risks before injuries happen.
