Name a safety procedure when using ladders.

Ensuring the ladder is stable and positioned on a firm base is crucial for safe ladder use. A stable ladder reduces the risk of slipping or tipping over, which can lead to falls and serious injuries. This practice involves checking that the ladder is on level ground or secured properly if the ground is uneven. Additionally, the angle of the ladder should be appropriate, typically at a 75-degree angle, to provide maximum stability while in use. This safety procedure minimizes hazards and creates a safe working environment when using ladders for maintenance or other tasks.

The other choices suggest practices that can compromise safety, such as keeping tools in your pocket, which could lead to loss of balance or increased risk of falling. Leaning a ladder against a wall without proper support can create instability, and using ladders only on windy days is not appropriate, as high winds can significantly increase the chances of accidents. Proper ladder safety protocols are essential to prevent injuries and ensure a safe working environment.
