How can you determine the right-hand side of an escalator?

Determining the right-hand side of an escalator involves understanding the perspective from which the reference point is established. When standing on the lower landing and looking up toward the upper landing, you are aligned with the direction of travel of the escalator. This viewpoint allows you to see the escalator’s inclination and helps clarify which side corresponds to the right side from a user’s perspective.

This method is standard practice in the industry because it provides a consistent frame of reference for installation, maintenance, and safety procedures. It ensures that everyone working with or around the escalator has a unified understanding of directional terms, which is crucial for effective communication and adherence to safety guidelines. The other options do not consistently offer the proper perspective, as they might lead to confusion or misuse of directional designations depending on where a person is standing.
