8 Safety Information Safety Precautions for Swing Gates and Ornamental "Grill Type" Gates ENTRAPMENT ZONES Pedestrians must stay clear of the gate path, particularly the area where the gate can trap them, as shown in Figure 1. 01-G0665F18 Figure 1 Gate edges and/or photo-electric beams must be incorporated into the swing gate system to assist in the protection of people who may come near the gate operating system. Also, injuries can occur when people put their hands and arms through openings in a grill type gate and it is operated. This potential hazard can be averted by placing a screen mesh on the gate to prevent access through the openings. See Figure 2. Photo-Electric Beam Always test Gate Edges and Photo Beams anytime they are adjusted or serviced. Gate Edge on Leading Edge of Gates Doc 01-G0665 Rev C Gate Edge Figure 2 01-G0610F4 Screen Mesh
