Which guidelines advise following industry standards during installation?

• A. Hoistway Travel Check
• B. Jumper Plugs
• C. Safety Guidelines
• D. Hydraulic Power Source

Answer: (C)

The core idea here is that safety guidelines tell installers to follow industry standards during a job. These guidelines lay out the accepted rules, codes, and manufacturer instructions that govern how an escalator or moving walk should be installed. By following them, workers ensure the equipment is installed correctly, safely, and in a way that complies with recognized standards, reducing the risk of hazards and ensuring reliable operation.

The other items refer to a specific task or part rather than a guidance framework. A hoistway travel check is a particular verification step, jumper plugs are electrical components used in circuits, and a hydraulic power source is a type of power supply. They don’t embody the overarching instruction to adhere to industry standards during installation.
