What happens to the capacity of elevating platforms when water is flowing?

When water is flowing from an aerial ladder or elevating platform, the capacity available for personnel and equipment is affected because the weight of the water needs to be considered in the overall load. Typically, when water is flowing, the capacity is reduced to ensure safety and stability. A reduction to 500 pounds accounts for the necessary weight of the water without compromising the structural integrity of the platform or the safety of personnel. This limitation helps to prevent overloading, which could lead to potential failure of the aerial device. Ensuring that the platform is operated within these guidelines is crucial for maintaining safety during fire suppression efforts or rescue operations.
