When inspecting an escalator, what is the primary function of the comb plate impact device?

To adjust the speed of the escalator
To ensure passenger safety by stopping the escalator if the comb plate is deflected
To maintain the alignment of the steps
To regulate the direction of the escalator

The correct answer is: To ensure passenger safety by stopping the escalator if the comb plate is deflected

The primary function of the comb plate impact device is to ensure passenger safety by stopping the escalator if the comb plate is deflected. This device is crucial because the comb plate is the area where the escalator steps meet the landing, and it can be a point of potential entrapment or hazard. If an object or a person interferes with the comb plate's function, the impact device detects this deflection and activates a safety mechanism to halt the escalator, preventing accidents and injuries. This feature is essential for maintaining safe operations, and its design specifically addresses the safety concerns associated with escalators, making it a vital component in the overall safety system. The other options, while related to escalator function, do not pertain directly to the primary safety role of the comb plate impact device.
