In a Vertical Lift Gate Entrapment Zone, entrapment is triggered when the gap at the bottom of the gate is less than how many inches?

In a Vertical Lift Gate Entrapment Zone, entrapment is triggered when the gap at the bottom of the gate is less than how many inches?

• A. 12 inches
• B. 16 inches
• C. 4 inches
• D. 8 inches

Answer: (B)

Entrapment safety for a vertical lift gate hinges on a defined bottom entrapment zone. If the gap between the bottom of the moving gate and the surface it closes toward becomes smaller than the designated threshold, the risk of trapping a body part increases and safety controls must stop or reverse the gate. The threshold used here is sixteen inches, so a bottom gap smaller than sixteen inches indicates an entrapment condition. This value is chosen to reflect typical human dimensions and to give protective devices enough margin to detect and react before injury could occur. That’s why the correct interpretation centers on the sixteen-inch boundary.
