According to standards, cable tray systems __________ shall be used in hoist ways.

Cable tray systems shall not be used in hoist ways due to safety and operational concerns outlined in electrical standards. Hoist ways are vertical shafts that accommodate elevators or other lifting mechanisms, and the presence of cable trays in these areas can pose significant hazards. For instance, they may obstruct safe access or escape routes during emergencies and can interfere with the operation of the elevator system itself.

Using cable trays in hoist ways can also complicate maintenance and inspection processes. Equipment within hoist ways needs to be easily accessible and free from additional structures that could hinder movement or the functionality of the equipment. This is why electrical standards explicitly prohibit their use in such environments, ensuring that safety, maintenance efficiency, and operational integrity are prioritized.
