What should be done before using a ladder when working on installation projects?

Before using a ladder, checking the stability of the ground is essential for ensuring safety during installation projects. A stable surface is crucial to prevent the ladder from slipping or tipping over, which can lead to accidents and injuries. Even if the ladder itself is in good condition, unstable ground can compromise its effectiveness.

Ladders should be placed on firm and level surfaces whenever possible. Different surfaces, such as mud, gravel, or uneven terrain, can increase the risk of accidents. By ensuring that the ground is stable, workers can create a secure base for the ladder, thereby enhancing safety.

While all the other choices address important safety considerations, such as checking for nearby electricity and verifying the ladder's height, the stability of the ground is foundational. If the ground is not stable, even the best ladder practices may not suffice to ensure safety. Thus, prioritizing the assessment of the ground stability before ladder use is critical in installation projects.
