Final step ensuring the installation area is tidy?

• A. Chassis Installation
• B. Customer Demonstration
• C. Cleanup
• D. Measurement Sheet

Answer: (C)

Final cleanup is the last step because it closes the job by making the installation area safe, clean, and ready for use. After the escalator or moving walk is in place, clearing debris, stowing tools, removing waste, and ensuring floors and access paths are clean removes trip hazards and signals that the project is finished. This step also helps prevent damage or loss of small components left behind and supports a smooth handover to the customer or building management.

Other activities fit earlier in the process: installing the chassis is part of the construction work, not the finishing touch; showing the customer how the unit operates typically happens after the system is ready for demonstration; and recording measurements is documentation done during or after the installation, not the final cleanup.
