What is critical for ensuring the safety of glass panel installation on escalators?

The correct choice emphasizes the importance of using appropriate tools during the installation of glass panels on escalators. Using the right tools ensures that the installation process adheres to safety standards and reduces the risk of accidents. Tools that are specifically designed for glass handling can minimize the chances of breakage and allow for precise placement, which is crucial given the weight and fragility of the materials involved.

While other factors such as worker experience, panel thickness, and weather conditions can influence the overall installation procedure, the use of appropriate tools directly relates to the immediate safety of the installation process. Proper tools help in securely fastening the glass, reducing stress on the material, and effectively managing any unique challenges that might arise, thus safeguarding both the workers and the escalator's operation.
