Codes and standards provide a roadmap for maintenance and inspection as protective measures.

by Louis Bialy

Maintenance and inspection have been recognized for many years as essential functions to ensure the safety of elevators and escalators. It is acknowledged that safety is a quality that can be continuously improved with the passage of time, although there is always an element of risk inherent in any device or system. Risk is a complex entity that is difficult to quantify; however, the need for structured processes aimed at assessing and reducing risk has gained momentum over the years. ISO 14798 Lifts (elevators), escalators and moving walks — Risk assessment and risk reduction methodology has become widely used in the elevator industry on a global basis. This methodology has many applications in design, development and ongoing use of elevator equipment.
