What is the goal of proper comb teeth alignment?

The goal of proper comb teeth alignment is primarily to ensure passenger safety. Comb teeth are the projections at the entrance and exit of an escalator that serve as a critical safety feature. Their alignment is essential to prevent the risk of entrapment or tripping as passengers step on or off the escalator. When comb teeth are aligned correctly, they help facilitate a smooth transition onto and off the escalator, significantly reducing the chance of accidents.

While enhancing operational efficiency, reducing maintenance costs, and even aesthetic appeal are important considerations in the context of escalator operation, they do not directly contribute to passenger safety in the way that proper comb teeth alignment does. Ensuring that these safety features are correctly positioned is a fundamental requirement in escalator design and maintenance protocols.
