How should the edges of elevator doors be designed for safety?

The design of elevator door edges is critical for safety, and beveled or rounded edges are recommended to minimize the risk of injury to passengers. A beveled or rounded edge reduces the likelihood of sharp corners that could lead to cuts or bruises when individuals are entering or exiting the elevator. This design also enhances the overall safety of the elevator by facilitating smooth operation, as beveled edges allow for easier alignment with the door frame.

In contrast, flat edges pose a greater risk of injury due to their sharpness, making them less desirable from a safety perspective. Covering the edges with rubber, while it could provide some cushioning, does not inherently address the fundamental design of the edges that could lead to accidents. Similarly, reinforcing the edges with metal might increase durability, but it does not improve the safety aspect of preventing injuries from sharp corners. The focus on beveling or rounding edges shows a commitment to passenger safety and adherence to industry best practices.
