When should a thorough inspection of a mobile ladder be conducted?

A thorough inspection of a mobile ladder should be conducted at the time of purchase and before its initial use to ensure that it meets safety standards and is free from defects that could compromise its performance. This initial inspection allows users to confirm that the ladder has no manufacturing flaws or damage that may have occurred during shipping or handling.

While it's also important to conduct regular inspections throughout the ladder's lifespan, such as before each use or after any incidents, the initial inspection is crucial because it establishes the safety foundation for future use. It ensures that the ladder is ready to be used in a safe and effective manner right from the start. Regular monthly inspections or checks after incidents are essential for ongoing safety, but they follow the critical first step of ensuring the ladder was safe at the point of purchase and prior to its first use.
