What precautions should be taken during escalator installation?

During escalator installation, it is essential to focus on proper alignment, securing components, and verifying electrical connections to ensure a safe and functional installation. Proper alignment is critical as it ensures that the escalator functions smoothly and reduces the risk of mechanical failure. If components are not securely fastened, this could lead to dangerous situations such as the escalator getting misaligned or even detaching from its mounting, potentially causing accidents. Moreover, verifying electrical connections is vital for the safe operation of the escalator, ensuring that all systems function correctly and safely without electrical failures.

The other options, while they may contain elements relevant to escalator installation, do not emphasize the crucial safety and operational protocols necessary for installation. Using only local materials may not guarantee the quality or standards required; user feedback is essential during installation for safety and usability, and making aesthetic changes before the system is properly secured can lead to significant safety hazards.
