Which regulation regarding the use of stepladders must be met?

The correct regulation regarding the use of stepladders relates to the angle at which they are placed. When using a stepladder, it is essential to ensure that the base is positioned correctly to maintain stability and prevent tipping. An angle between the foot of the ladder and the ground that exceeds 80 degrees indicates that the ladder is too steep and increases the risk of loss of balance and tipping over.

Ensuring the correct angle—typically between 75 and 80 degrees—is crucial for safety. This angle supports the weight evenly and allows for better balance when climbing and working from the ladder. Meeting this regulation helps reduce accidents and injuries associated with ladder use.

Other options regarding the ladder’s surface and material, or the maximum height, do not align with the key structural and safety considerations for proper ladder use. Non-slip surfaces, while important for safety, are not a regulatory requirement stated in the context of this question. Additionally, while material and height specifications may exist for certain circumstances, they do not directly address the critical requirement for stability that the angle of the ladder does.
