What is the maximum allowable clearance between the step tread and the balustrade curtain guard?

The maximum allowable clearance between the step tread and the balustrade curtain guard is 1/8 inch. This specific measurement is crucial for ensuring the safety and security of elevator passengers. The purpose of maintaining such a small clearance is to prevent any potential hazards that could arise from larger gaps, such as individuals' clothing or body parts becoming trapped. Adhering to this standard helps maintain compliance with safety codes and reinforces the structural integrity of the elevator's design.

In the context of elevator safety, tighter tolerances are necessary to provide optimal protection against entrapment risks. This is particularly relevant for escalators and moving walkways, which require careful attention to gaps to mitigate accidents. Understanding the stipulated clearance is part of established safety practices, emphasizing the industry's commitment to passenger safety and adherence to regulations.
