According to Entrapment Zone exceptions, for a Horizontal Swing Gate, how many independent entrapment protection means are required for each direction of travel if there is no entrapment zone in that direction?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (A)

The key idea is that entrapment protection rules flex based on where a guard can trap a person. When there is no entrapment zone in the direction the gate moves, the risk of entrapment in that direction is essentially absent, so only one independent entrapment protection means is required for that direction. The purpose of having two independent means is to provide redundancy in a real entrapment zone; without such a zone, one protective device suffices to stop the motion if contact occurs. In the opposite direction, if an entrapment zone exists, you would typically need two independent means. So for a Horizontal Swing Gate with no entrapment zone in that direction, one independent entrapment protection means is required.
