Which of the following is considered a dangerous practice when operating a scissor lift?

Using a scissor lift while it is in motion is considered a dangerous practice because the stability of the lift is compromised during movement. When a scissor lift is in operation and moving, the platform can be subject to increased risk of tipping over, especially if the environment is uneven, or if the lift is being moved with a load that shifts during transit. Operators may also be at a greater risk of falling or losing balance if proper safety measures aren’t followed.

In contrast, using the lift while stationary is a standard practice that ensures stability, adjusting the lift from the ground is a safety protocol to prevent accidents, and operating within load capacity is essential for maintaining safety and stability while using these machines. Therefore, moving the lift while occupied poses the highest risk and is why it is regarded as a dangerous practice.
