What is the biggest cause of ladder accidents?

Posted on 3rd Mar, 2026 | By Niamh Holden

Ladders may seem simple, but they remain one of the main causes of workplace and home injuries. Whether you are a tradesperson or just doing some DIY, ladder accidents can happen fast and often lead to serious injuries.

So, what is the biggest cause of ladder accidents?

The most common reasons for ladder injuries are incorrect use, overreaching, and/or incorrect setup. Accidents are rarely caused by a single issue; they’re usually due to poor judgment, rushed work, or unsafe conditions.

This blog looks at the main reasons ladder accidents occur and what you can do to prevent them.

What is the biggest cause of ladder accidents?

Ladder accidents are usually caused by improper use, particularly when users overreach, fail to maintain three points of contact, or position the ladder incorrectly.

Falls from height are a leading cause of workplace fatalities and serious injuries, and ladders are frequently involved. While ladders are not inherently unsafe, they are often used incorrectly, especially for jobs that should involve a scaffold tower, podium step, or platform.

The main problem is that people use ladders as if they are stable work platforms, but ladders are really meant for short, low-risk tasks.

Why does overreaching cause so many ladder falls

Overreaching is one of the most common mistakes people make when using ladders.

This happens when someone leans too far to the side instead of climbing down and moving the ladder. Even a small change in body weight can make the ladder unstable, especially if it is not secured.

Why overreaching is so dangerous:

• It shifts your centre of gravity outside the ladder’s side rails
• It reduces your ability to grip properly
• It can cause the ladder to slip or twist
• It increases the chance of losing balance suddenly

A good rule to follow is to keep your belt buckle between the ladder’s side rails. If your hips go past the rails, you are reaching too far.

Poor ladder positioning and unstable ground

Another major cause of ladder accidents is improper placement of the ladder.

If the ladder is at the wrong angle, it can easily slip at the bottom or fall backwards. Many people still set ladders too upright, thinking it is safer, but this increases the risk of tipping.

Common ladder positioning mistakes include:

• Placing the ladder on gravel, mud, or uneven paving
• Setting it up on slippery surfaces (wet decking is a big one)
• Not securing the top of the ladder
• Using makeshift supports like bricks or timber
• Positioning the ladder too steeply or too shallowly

A common guideline is the 4:1 rule. For every 4 units of height, the base of the ladder should be 1 unit away from the wall.

Using the wrong ladder for the job

Not all ladders are designed for all tasks.

Using a lightweight domestic ladder for heavy trade work is very risky. Also, using a short ladder and standing on the top rungs to reach higher is one of the main reasons people fall.

Wrong ladder choices often include:

• Using step ladders as leaning ladders
• Using extension ladders indoors without stability
• Using ladders that are too short
• Standing on the top step or top rung
• Choosing ladders not rated for the user’s weight and tools

Often, ladder accidents happen because someone tries to “make do” instead of using the right equipment for the job.

Ladder condition and lack of inspection

Even if you use a ladder correctly, it can still be dangerous if it is damaged.

Cracks, loose rungs, worn feet, and bent stiles all reduce ladder stability. Many accidents occur because ladders are old, poorly maintained, or not checked before use.

Signs a ladder should not be used:

• Loose or missing rungs
• Damaged locking mechanisms
• Slippery, worn feet
• Cracks in fibreglass ladders
• Bent aluminium treads / rungs / stiles
• Rust on steel components

At work, ladders should be checked regularly. At home, it is still good practice to do a quick safety check each time you use a ladder.

Human error: rushing, fatigue, and distraction

One of the most overlooked reasons for ladder accidents is people’s behaviour.

People often rush, especially when they think the job will only take five minutes. This way of thinking is very common when clearing gutters, painting, or going into loft spaces.

Being tired also plays a big part. Working at height requires good balance and coordination, which can be affected by tiredness, alcohol, illness, or distraction.

These accidents can be caused by:

• Carrying tools in your hands while climbing
• Not maintaining three points of contact
• Being distracted by phones or other people
• Trying to work too fast
• Working when tired or stressed

Even a brief lapse in attention can lead to a serious fall.

Weather and environment conditions

Many outdoor ladder accidents happen in autumn and winter due to slippery ground.

Strong wind gusts can cause imbalance; wet or icy rungs can cause you to slip from the ladder; and even fallen leaves can make ladder work hazardous.

If the weather is bad, it is usually best to wait or use different equipment to reach the area safely.

How to reduce ladder accidents

Preventing ladder accidents mostly comes down to being prepared and following good habits.

Here are practical ways to reduce risk:

Use the correct ladder

Always pick a ladder that fits the height you need, the weight it must hold, and the work site.

Set it up properly

Set the ladder at the right angle and make sure the base is steady and level.

Avoid overreaching

Climb down and move the ladder instead of leaning to the side.

Maintain three points of contact

Maintain three points of contact at the working position. This means two feet and one hand, or when both hands need to be free for a brief period, two feet and the body supported by the ladder / step ladder.

Inspect the ladder before use

Check the rungs, rails, feet, locks, and hinges before you use the ladder.

Wear proper footwear

Do not wear shoes with slippery soles. Safety boots or sturdy shoes work best.

Don’t work too long on a ladder

As a guide, if your task would require staying up a leaning ladder or stepladder for more than 30 minutes at a time, it is recommended you use alternative equipment.

For both professional and home use, Browns Ladders provides reliable access equipment built for safety and durability. This helps you get your work done properly and safely.

FAQs

What is the number one cause of ladder accidents?

The number one cause is incorrect ladder use, particularly overreaching and poor positioning, which can cause the ladder to slip or tip.

Are ladder accidents common in the UK?

Yes. Ladder accidents remain a major contributor to falls from height, which are among the leading causes of workplace injuries in the UK.

Is it safe to stand on the top step of a ladder?

No. Ladders are not designed for standing on the top step or top rung. A platform stepladder is however designed for that purpose.

What is the safest type of ladder to use?

The safest ladder depends on the job. For many tasks, platform ladders, podium steps, or mobile scaffold towers are safer than traditional leaning ladders.

How can I stop a ladder slipping?

Use non-slip feet, place it on stable ground, follow the correct angle, and secure it at the top or bottom where possible.
