Safety:(2) Legislation and Escalators: (2. 4) Key Safety Features: Deflector Brush: If the sensor notices a speed difference between the handrail and the steps, it sounds an alarm, pauses, and then automatically stops the escalator. In these situations, the escalator must be serviced by authorized personnel before returning to an operable state. Missing step detectors: Depending on the manufacturer and model, this sensor is either optical or physical. When a missing step is detected, the escalator automatically shuts down. Raised step edges: In some models, a difference in tread height is utilized to keep passengers' feet from the skirt board. Safety instructions: A sign, typically posted on both escalator newels at the entrance landing platform. In some situations, safety precautions are posted on walls near the escalator, included on freestanding signs, oras in some modelsprinted on the riser surface itself. Sensor switch: In automatic-start/stop escalators, this sensor automatically engages the escalator motion when a rider is detected on the first step of the entrance landing platform, and stops the escalator when there are no riders on the unit. Step demarcation lights: Either fluorescent or LED lights (traditionally green in color) located inside the truss. The illumination between the steps improves the passengers' awareness of the step divisions. Step demarcation lines: In order to clearly delineate the edges of each individual step, manufacturers offer steps trimmed in yellow, either painted or with plastic inserts
