Safety Precautions To Take Before Climbing Up A Ladder:

Ladder accidents and injuries have become a major issue in the United States in the past few years. Over 300,000 people get injured every year on average.

Here are the safety precautions you can take to avoid such incidents:

  • Measure the weight before climbing up the ladders.
  • You should never cross the weight capacity of your ladder. 
  • Measure your weight and compare it with the ladder according to the types and see the ratings to match your choice.
  • Sometimes weight is not the factor for ladder injuries. Make sure to place the ladder on even ground.

How Can You Calculate The Weight Capacity Of A Ladder?

In order to calculate the weight capacity of a ladder, you need to add:

  • Your weight,
  • Equipment you want to carry while climbing
  • Your Clothes, protective measures, and shoes,
  • The tools you are planning to keep on the ladder while you are working.

Some people forget to calculate and add the weight of extra materials. One of the main reasons why they fail to correctly calculate the weight capacity of a ladder.

Does The Length Of A Ladder Mean It Carry More Weight?

Never! The length of a ladder does not determine the weight capacity of a ladder. A tall ladder does not necessarily mean it can hold weight beyond its limit. There are no connections between the weight of the ladder and the height. The ladder’s weight capacity depends on the materials and types of the ladder.

Which Type Of Ladder Is Best For A Heavy Person?

For a heavy person, it is recommended to climb a Type II ladder as the weight capacity is around 180-250 pounds. This type II ladder is more than enough for a heavy person. Type I will be too much for a heavy person even though it will be a safe option but this type of ladder is mostly used for construction sites and in industrial places.

Can You Trust The Weight Ratings Of The Ladder?

Definitely, the weight ratings of your ladder are more than accurate. The government has imposed a very strict law and each ladder is very well tested and demonstrated with a very heavyweight of around 1000 pounds right after the manufacturing process is done.
