What height and locking features are specified for the safety device used at the lift entry?

• A. 24 inches high, non-locking
• B. 42 inches high, self-closing, self-locking
• C. 36 inches high, self-locking
• D. 60 inches high, self-closing

Answer: (B)

A safety gate at the lift entry must provide a sturdy, automatic barrier to prevent accidental falls into the shaft while still allowing authorized access when needed. The height of forty-two inches is chosen because it’s tall enough to deter climbing and stepping over, while still being practical for use in the entrance area. The combination of self-closing and self-locking means the gate will automatically return to the closed position and will lock on its own after closing. This prevents the gate from being left open or easily opened by someone who should not have access, maintaining a continuous protective barrier. Shorter gates or those that are not self-closing or self-locking don’t provide the same level of assurance, since they can be left ajar or easily bypassed.
