Guidelines for platform and stairway chairlifts.

• A. Data Plate
• B. Hinged Track
• C. Safety Standard ASME 18.1-2005
• D. Carriage

Answer: (C)

Safety Standard ASME 18.1-2005 provides the guidelines for platform and stairway chairlifts. This standard sets the required safety features, performance criteria, and testing and maintenance procedures specific to these lifts, covering aspects such as enclosure and gates, interlocks, emergency stop devices, speed limits, braking, drive systems, and inspection intervals. It is the formal reference inspectors and installers rely on to determine compliance and safe operation across different installations. Other options don’t establish the comprehensive safety criteria or testing requirements needed for these lifts—data plates merely identify equipment information, while hinged tracks and carriages are individual components rather than the full safety guidelines.
