What can occur if comb teeth are not properly aligned with step treads?

When comb teeth are not properly aligned with the step treads of an escalator, it can lead to potential accidents. The comb plates serve as a crucial safety feature by facilitating a smooth transition between the escalator steps and the landing areas. Misalignment can create a gap or a catch point, which increases the risk of users tripping or getting their footwear caught. Such situations can lead to falls and injuries, highlighting the importance of correctly installing and aligning these components for user safety. Proper alignment not only ensures the escalator functions smoothly but significantly reduces the chance of accidents occurring during its operation.
