4 Safety Rules When Using A Ladder

Here are some statistics that may cause you to be more careful when using a ladder.
The American Academy of Orthopedic Surgeons published some statistics that illustrate the dangers of ladder accidents.

• In the U.S. more than 500,000 people a year are treated for ladder related injuries, and that number does not include people who suffered injuries but did not go to a medical care provider for treatment.
• About 300 people in the U.S. die from ladder related injuries annually.
• Estimated annual cost of ladder related injuries is $11 billion, including work loss, medical, legal, liability, and pain and suffering expenses.

The notion that ladder safety begins when you place your foot on the first step is wrong. Ladder safety really begins when shopping for a ladder — a daunting task considering all of the choices. First is ladder style – step or extension? Often you will need both. A stepladder can be used indoors and outdoors, but has height limitations. An extension ladder is used primarily outdoors where extra height is needed as in the case of a two-story home. An extension ladder can be useful indoors where unusually high ceilings exist.

Next is size. When it comes to ladders size does matter. For stepladders, the ladder’s height plus 4 feet equals the total reach. For example: a 4-foot ladder can be used to reach an 8-foot ceiling. Use a 6-foot ladder to reach a 10-foot ceiling, and so on. For an extension ladder, keep in mind that the base and upper sections must overlap. So, a 20-foot extension ladder is only good for about 17-feet. By the way, the ladder must travel above the roofline 2- to 3-feet so that it can be used for balance as you climb onto the roof.

Ladders are sold by “duty rating” – how much weight a ladder is rated to carry. The more weight it will hold, the stronger it must be. The American National Safety Institute (ANSI) establishes duty rating. The five duty ratings and their respective load capacities are as follows: Type IAA special duty – 375 pounds; Type IA extra heavy duty – 300 pounds; Type I heavy duty – 250 pounds; Type II medium duty – 225 pounds; and Type III light duty – 200 pounds. When in doubt, always err on the side of a heavier duty rating.

The final step in choosing a ladder is construction material. The choices are wood, aluminum and fiberglass. The oldest and most familiar ladder is one made of wood. Wood ladders have a solid, sturdy feeling. However, the fact that they are heavy makes them a bit cumbersome and somewhat difficult to transport. Also, wood must be regularly maintained to prevent cracking, splitting and rot. Wood is economical and is said not to conduct electricity when clean and dry. If you do lots of electrical work we suggest that you choose a fiberglass ladder.
Ladders made from high-strength aluminum are a lightweight, rot-free alternative to wood. But aluminum ladders have been around long enough to prove that they don’t last any longer than wood. Salt air or chemicals can corrode – and weaken – an aluminum ladder in no time.

Fiberglass has become as popular as aluminum was when it first replaced wood. Fiberglass ladders are lighter than wood but heavier than aluminum. They aren’t subject to rot, they don’t bend easily and they do come in several attractive colors. Manufacturers say that they will last generations – just what they said about aluminum. We know that plastics and resins oxidize in the same fashion as all other carbon-based materials. Only time will tell whether fiberglass will last any longer than the others.

Choosing the right ladder is only part of the safety equation. Proper use and maintenance will help ensure that you don’t become one of the unfortunate statistics that we mentioned earlier. Always read and abide by the instruction labels and stickers on the ladder BEFORE setting foot on a ladder. Failure to do so could have devastating consequences. Make a thorough inspection of the ladder to be sure that it is safe and in good working order. If you have a wooden ladder that’s rickety or broken take a saw and cut it into pieces. Then use it as firewood. There’s no excuse for using an unsafe ladder. Even a perfectly good ladder can be unsafe if not used properly.

Here are some rules and a few tips that could help prevent a ladder accident in your home, and perhaps serious injury:

Rule 1 – never use a worn-out ladder. In some instances they can be repaired, but more often than not, it is advisable to get a new one.

Rule 2 – never use a ladder unless it is rated to carry your weight. Ladders are rated by the amount of weight that they can carry. If the salesperson at the store can’t tell you the weight that the ladder is capable of carrying, find another store.

Rule 3 – use a ladder that is the right length for the job. For stepladders, the ladder’s height plus 4 feet equals the total reach. For example: a 4-foot ladder can be used to reach an 8-foot ceiling. Use a 6-foot ladder to reach a 10-foot ceiling, and so on. And that warning at the top, “this is not a step,” means just that. For an extension ladder, keep in mind that the base and upper sections must overlap. So, a 20-foot extension ladder is only good for about 17-feet. By the way, the ladder must travel above the roofline 2- to 3-feet so that it can be used for balance as you climb onto the roof.

Rule 4 – Rest the ladder properly. Don’t rest the high leg on a block of wood or a brick. Instead, dig a hole for the lower leg. Also, don’t stand the ladder up at too little or too great of an angel. The safe angle is at about 75 degrees. Remember, too, much angle reduces the ladder’s strength and not enough angle could cause you to tip backwards. Seventy-five degrees is an angel equal to when the minute hand of a clock is directly in between the 12 and the one, or 75 degrees from the three.
