Claim 10:
11. A safety system comprising an entrapment preventer in the form of a movable safety gate, the safety system comprising:
a confined space comprising at least a first access opening comprising a width and a selectively openable and closable access barrier which is selectively movable from a closed position to an open position, said access barrier openable to said open position which permits ingress to and egress from said confined space through said first access opening and closable to said closed position which does not permit ingress and egress through said first access opening;
a safety gate movable from a closed position, wherein the gate extends across a substantial portion of the width of said first access opening said first access opening and obstructs the ingress into said confined space through said first access opening, to a safety position which does not permit said access barrier to be positioned in said closed position;
said access barrier movable independent of said safety gate such that movement of said access barrier does not cause movement of said safety gate.
