Abstract: A remote isolation system (10) for a plant comprising equipment (20,21) energizable by an energy source (30) and a control system (50,260) enabling automated isolation of the equipment (20,21) from said energy source (30) to an isolated state when authorized by the control system (50,260), wherein said control system (50,260) enables remote isolation of the equipment (20,21) by one or more mobile isolation device(s) (120) provided as part of the remote isolation system (10) and configured to request the control system (50,260) to authorize equipment (20,21) isolation.

Abstract: An equipment isolation system (10) for remotely isolating equipment (20, 21, 210, 250) in a plant comprising equipment (20, 21, 210, 250) energisable by an energy source and a control system (50) for controlling operation of said equipment (20, 21, 210, 250) and isolation of said equipment from said energy source to an isolated state by an operator, wherein said control system (50, 260, 700) includes an identification device (790) for an operator to provide operator identification data; and a processor for comparing said operator identification data with stored identification data (261) for operators authorised to use the equipment isolation system (10) wherein said control system (50, 260, 700) is configured to enable use of the equipment isolation system (10) by said operator only where the processor matches operator identification data provided to the identification device (790) and said stored identification data (261).

Abstract: An equipment isolation switch assembly (200) for use in a remote isolation system (10) for isolating an equipment item (20,21) comprising an equipment isolation switch (400) movable between a first position (NORMAL) in which said equipment item (20,21) is energized by an energy source (30) and a second isolated position (ISOLATE) in which said equipment item (20,21) is isolated from said energy source (30) and an actuating device (500) co-operable with the equipment isolation switch (400) to move it between said first and second positions wherein said isolation switch assembly (200) includes at least one securing means (291,405) for securing said actuating device (500) in co-operation with said equipment isolation switch (400) whenever in operative state.
