Exterior View of Sliding Gate Entrapment Zone by Nice/HySecurity
Last month I discussed “Protection Against Entrapment In A Sliding Gate Installation“. There are three possible areas (or zones) where people can be trapped on the interior, or owner, side of the sliding gate during the gate operation. (Read the article for details.) In this article I will examine the public or exterior view of the sliding gate for potential entrapment.
We must assume there are barriers such as fencing or walls (as shown in the photo above courtesy of Nice/HySecurity) preventing pedestrians from going around the gate. Then there is a single area where pedestrians can be trapped by the closing of the gate. It is to the far left where the gate would come to rest in its closed position. This area requires entrapment protection.
The entrapment area is shown again to be protected by a photoelectric beam and it reflector in the diagram. When someone interrupts that beam a signal is sent to the gate operator to stop and return to the open position. This is similar to the operation of modern garage doors to prevent toddlers on bikes being crushed by a closing door. Our overall goals are protecting the safety of people in the area and avoiding potential liability.
Entrapment Zone in Other Gate Security Applications
I have also written about gate security applications and protecting the entrapment zones in other applications. I wrote about “Entrapment Zone Consideration in a Barrier Gate Installation”, “Entrapment Zones in a Vehicular Double Swing Gate System” as well as “Checking Entrapment Zones | Part of Vehicle Gate Maintenance“.
Once again, please refer to Underwriter’s Laboratory (U.L.) code UL-325 and ASTM (International) F-2200 for a further explanation of applicable codes to your installation. As always, we caution you to consult with legal counsel regarding liability issues involved with your vehicle gate system(s).
