Any alteration to passenger car ventilation is classified as what type of alteration?

Altering passenger car ventilation is classified as a minor alteration because such modifications typically do not affect the overall safety, structure, or primary function of the elevating device. Minor alterations are those changes that are not likely to introduce significant risks or structural changes, which is the case with adjustments to passenger car ventilation systems. These adjustments usually focus on improving comfort or air quality without compromising the operational integrity of the elevator.

Major alterations, on the other hand, involve significant changes that could affect safety or the performance of the device, such as modifications to the drive system or structural components. Temporary alterations refer to modifications that are not intended to be permanent, and while they might not apply here, they are also not relevant to changes meant for ventilation systems. Thus, classifying the ventilation change as a minor alteration is specifically aligned with established industry standards regarding safety and modification categories.
