Abstract
The safety systems enhance the safety of confined spaces which can present a danger to human occupants who may become entrapped within the confined space during a dangerous condition. The safety systems are particularly useful with confined spaces having access openings and a door or other movable barrier for the access opening. The safety systems having movable safety gates proximate the access openings. The disclosed safety gates are movable from a closed position where the safety gate forms a physical barrier which inhibits human entry into the confined space to a safety position where the safety gate prevents the door from closing and entrapping a person within the confined space.
Claims15
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 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.
Operating equipment comprising:
- a structure defining a confined space and comprising at least a first access opening comprising a width for ingress into and egress from said confined space;
- a source for supplying at least one operating condition to the confined space for performing an operation, wherein said at least one condition would present an imminent danger to the survivability of a human adult present within said confined space during said operation;
- a selectively openable and closable access barrier which is selectively movable from a closed position to an open position, said access barrier openable to an open position which permits ingress to and egress from said confined space through said first access opening and closable to a 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 and obstructs the ingress of an adult human 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.
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.
