Which is NOT a characteristic of a properly supported ladder?

A properly supported ladder must have certain characteristics to ensure safety and effectiveness during use. One key characteristic is that the top of the ladder should extend above the landing it is resting against, which provides a secure handhold for the user as they step on or off the ladder. When the top of a ladder extends below the landing, it creates a risk of losing balance and makes it more challenging to safely transition between the ladder and the surface above.

Other important characteristics include having a stable base, ensuring that the ladder is placed at the proper angle of around 75 degrees, and selecting a height appropriate for the task being performed to minimize the risk of accidents or falls. These features work together to provide a safe working environment, reducing hazards that may arise from improper ladder use.
