Patent number: 6098750Abstract: A safety system which protects the open side of a mezzanine, loading dock or other elevated work area when in use. The safety system is easy to use while requiring only minimal floor space. The safety system comprises two posts, a movable arm having a safety net and associated hardware such that when the safety system is in a first position the opening of the mezzanine or loading dock is substantially covered by the net. When the safety system is in a second position, the arm and net are out of the way, allowing access by workers and machinery to and from the open side. The operation of the safety system from the first position to the second position or vice versa is performed remotely from the open side, thus further reducing the risk of falling.Type: GrantFiled: November 24, 1997Date of Patent: August 8, 2000Assignee: Bay Nets, Inc.Inventors: Charles Gregory Reynolds, William K.
