Turbine Hall Corridor

A corridor in the turbine hall area at White Bay Power Station connects the main turbine hall floor to the switch house, the boilerhouse link way, and the service lifts. The corridor walls are painted brick, the paint applied in successive coats over decades, the most recent application a pale cream over earlier green. The floor is concrete with a non-slip aggregate finish worn smooth at the centre by foot traffic. Steel-framed doors with wired glass panels are fitted at each end of the corridor. A fire hose reel cabinet is mounted on the wall with a cast-iron surround. Emergency exit signage above each door is a painted metal plate. Cable trays overhead carry instrumentation and control cabling between the turbine hall and the switch house.

Service corridors at White Bay Power Station formed the circulation network between the main plant areas. The turbine hall, boilerhouse, switch house, and administration building were linked by covered corridors that allowed operators and maintenance staff to move between areas without going outside. During continuous operation the station was staffed around the clock, and the movement of personnel between the control room, the boilerhouse, and the turbine hall was a constant feature of each shift. White Bay ran from 1917 to Christmas Eve 1983. The corridors reflect the station's multiple build phases: the earliest links from 1917, the additions of the 1920s, and the connections built in the 1950s.
