What safety feature must be implemented when using ladders on job sites?

The requirement to inspect a ladder before use is crucial for ensuring safety on job sites. A thorough inspection helps identify any defects such as cracks, bent rungs, or worn components that could lead to accidents or falls. By checking for these issues beforehand, workers can minimize the risk of using a compromised ladder, which may otherwise lead to serious injuries.

Consider that while having a second worker hold the ladder adds an extra layer of support, it’s not always practical in every situation and does not address the ladder's structural integrity. Likewise, securing a ladder at the top is a beneficial practice, but it is often not possible for all types of ladders or situations. Limiting ladder use to short tasks can also be misleading, as ladders can be effectively used for longer jobs if used correctly and safely. Hence, the primary focus should be on the condition of the ladder itself, making the inspection process a foundational safety measure.
