4 Major Causes of Ladder Accidents

Posted by David Burch on

Think about the products you use every day. How many of those products are exactly the same as they were when your grandfather was using them?

I bet you can’t name very many.

Some of the very basic ones like a knife and fork or a needle haven’t changed, but most have. How many TV channels were there when you were a kid? What did your phone look like? Believe it or not, our phone was stuck to the wall and you had to turn a dial around for each number. How about your family car? Did it have seat belts or airbags? Ours didn’t; if my dad wanted us to sit down he would just tap the brakes and down you went. Why do cars have seat belts?

Safety through design

Silly question, right? Statistics show there are 10 million traffic accidents a year that result in more than 30,000 fatalities. We train people to avoid accidents, but we know they are going to have them. Because car companies know accidents are going to happen, they’ve added safety features that will protect the driver even when the driver does something wrong. Seat belts and airbags have been proven to reduce injuries and fatalities and now car companies are adding sensors that will stop your car before you run into something even if you aren’t stepping on the brakes. Seat belts and sensors are examples of safety through design, not just training.

The safest way to design a product is to design out all the dangers. If it’s impossible to design out all the dangers, then you guard against those dangers. The lowest form of design is putting a warning sticker on it. Have you looked at the side rail of a ladder lately? It’s covered in warning labels with tons of fine print. While other products have improved and become safer, ladder companies have just added more stickers to tell you what not to do.

Causes of ladder accidents

Grandpa’s ladder hasn’t changed much in design in hundreds of years. They’ve changed the material from wood to aluminum to fiberglass (which is non-conductive) but the basic design has remained unchanged. There are a lot of stickers telling you how to safely use the product and companies hold training classes to teach you how to use the product safely; but, statistically, we know people are still going to do things that will cause an accident. If we know these accidents are going to happen we can identify the causes and design safety features to prevent them.

1 Ladders are too heavy

In some service industries almost half of their ladder-related injuries are strains and sprains from handling a heavy ladder. Some workers are doing 8-12 visits a day with a 28-foot extension ladder that weighs more than 70 lbs. You thought you were tired at the end of a day. The solution to this problem is to make lighter ladders. New fiberglass materials are available and can reduce the weight of your ladder by 20 percent. Most ladder companies now offer a lighter weight version of some of their ladders.

2 People use the wrong ladder for the job

This happens mostly because the right ladder for the job is too heavy. If I have the choice to carry a 4-foot stepladder or an 8-foot stepladder, I’ll probably carry the 4-footer and try to make it work by climbing on the top step or top cap of the ladder to get the job done. The top step of a stepladder has a sticker on it that says, “This is not a rung. Don’t stand here.” If the only purpose for the top step is to hold the sticker telling you not to use it, why is it there in the first place? If the rung’s not there, you can’t use it, and, hopefully, it will discourage you from trying to stand on the top of the ladder.

3 Leveling a ladder

When I ask people how they level their ladders, the common response is bricks and boards.  There are several companies that make levelers you can add to your ladders. Some ladder companies are building leveling devices integrated right into the ladders.

4 Over-reaching

Improper leveling and over-reaching are the major causes of tip-and-fall accidents. These accidents cause thousands of disabling injuries and hundreds of fatalities every year. We train people to keep their bodies between the side rails of the ladder, but we know that doesn’t always happen. One solution to this problem is adding outriggers to the bottom of an extension ladder to increase the footprint. If the climber can’t get outside of the footprint of the ladder, they won’t be able to tip it over. Those outriggers would also level to the ground, giving the ladder a wide level base. Also, by adding a caged platform at the top of a stepladder, you can keep the user centered inside the footprint of a stepladder.

Training isn’t enough

OSHA has great ladder safety training on its website. The American Ladder Institute offers free online ladder safety training at its website,, but training alone is not enough. We know how people misuse ladders, so we can add safety features to prevent the accidents from happening—even when they are misused. We advocate for safety through design, not just safety training.
