Which change is classified as a minor alteration Type B?

The classification of minor alterations, particularly Type B, involves changes that do not significantly affect the safety or operation of the elevating device. In this context, any change to car ventilation is considered a minor alteration Type B because such modifications typically do not impact the overall functionality or safety features of the elevator system. They often target aesthetic or comfort factors without posing risks to the structural integrity or operational reliability of the elevator.

In contrast, installing a new elevator control panel or upgrading safety systems in the elevator would classify as more significant alterations, potentially requiring extensive evaluations and compliance checks due to their potential to influence overall system functionality and safety. Repainting the elevator car, while maintaining appearance and potentially small in scope, is generally viewed as maintenance rather than an alteration, which distinguishes it from procedural or technical changes classified under Type B.
