Is placing a mobile ladder on boxes or barrels to gain additional height acceptable?

Placing a mobile ladder on boxes or barrels to gain additional height is not acceptable because it compromises the ladder's stability and safety. Ladders are designed to be used on level, stable surfaces to ensure that they maintain their structural integrity and can support the weight of the person using them. When a ladder is elevated in this manner, it is more prone to tipping, slipping, or collapsing, which significantly increases the risk of falls and serious injuries. The proper use of a ladder requires adherence to safety guidelines that emphasize maintaining an adequate base and ensuring that the ladder is set up in a secure manner. This practice of using makeshift supports directly violates those safety standards.
