Which term denotes a solid barrier protecting the lift's runway area?

• A. Self-Closing Door
• B. LULA
• C. Runway Enclosure
• D. Safety Switch

Answer: (C)

The essential safety feature here is a solid barrier that encloses the running area of the escalator or moving walk, keeping people and objects away from the moving steps and machinery. This protective structure is known as the runway enclosure. It forms a continuous barrier around the runway, so the area where the steps move is not accessible from the sides or bottom, reducing the risk of entrapment, injury, or interference with the drive system. Other options describe different safety or access components that don’t serve as the full barrier around the runway. A self-closing door is just an access point that closes automatically, not the entire protective enclosure of the running area. A LULA is a type of elevator, not a runway barrier for escalators. A safety switch is a control device used to stop operation, not a physical barrier guarding the runway.
