The Ultimate Ladder Safety Quiz II

Ladder inspections are conducted before using the ladder to ensure that the rungs are clean and undamaged, the side-rails and locking devices are free of damage, and the non-skid safety feet are in place and undamaged. This comprehensive inspection covers all of the mentioned aspects to ensure the ladder's safety and functionality.

Aluminum ladders should not be used around electricity or when using power tools because aluminum is a good conductor of electricity. This means that if the ladder comes into contact with an electrical source, it can easily conduct the electricity and pose a risk of electric shock or electrocution to the person using the ladder. Therefore, it is important to use ladders made of non-conductive materials, such as wood or fiberglass, in situations where there is a potential for contact with electricity.

The proper selection of a ladder requires considering various factors, including the work site environment, the size of the ladder, and the total weight it can support. The work site environment is important to ensure that the ladder is suitable for the conditions and can be safely used. The size of the ladder is crucial to ensure that it reaches the desired height and provides stability. Additionally, the ladder should be able to support the total weight of the user and any equipment they may be carrying. Therefore, all of the mentioned factors are necessary for the proper selection of a ladder.

When using a ladder to access a roof, the ladder needs to extend 3 feet above the top support. This is to ensure stability and safety while climbing up or down the ladder. Having the ladder extend 3 feet above the top support allows for a secure handhold and prevents any accidents or falls. It is important to have this extension to provide a stable and reliable means of accessing the roof.

Falls from ladders can be caused by a combination of factors such as haste and lack of attention. When individuals are in a hurry or not paying proper attention, they may not take the necessary precautions while using a ladder, which can lead to accidents and falls. Therefore, the correct answer is "Haste & lack of attention."

Single and extension ladders require a level top support because this ensures stability and prevents the ladder from tipping over. If the top support is not level, the ladder may become unstable and pose a safety risk to the user. Therefore, it is important to always check and ensure that the top support of the ladder is level before using it.

The misuse of ladders leads to approximately 300 deaths per year.

When using a step ladder, it is important to never climb higher than the second step from the top cap. This is because climbing beyond this point can lead to instability and increase the risk of falling or losing balance. The top cap of the ladder provides stability and support, and going beyond the second step from the top can compromise this support, making it unsafe. Therefore, it is crucial to adhere to this safety guideline to prevent accidents and ensure personal safety while using a step ladder.

Stepping on the top three rungs of a ladder is dangerous because it increases the risk of losing balance and falling. The lower rungs provide a more stable and secure foothold, while the top rungs are narrower and less stable. By avoiding stepping on the top three rungs, one can minimize the chances of accidents and ensure their safety while using a ladder.

A ladder's weight rating refers to the maximum weight that the ladder can safely support. This means that the weight of the person or objects being placed on the ladder should not exceed this weight rating. It is important to adhere to the weight rating to prevent accidents or damage to the ladder.
