(Boiler and Compressor-House) The boiler and compressor-house are of brick construction. The boiler-house comprises two or three furnace/boilers, situated in a double span building with each span having a curved roof. Each span has a longitudinal glazed roof monitor with ventilation louvres along its length. The front of each span has an arched opening with two windows to its side, one window above the other. The rear of the boiler-house is devoid of windows. The boiler-house chimney is of a square design which is connected by a brick discharge flue to the boiler-house burners. The dimensions of the boiler-house are, 50ft x 45ft the building height is approximately 20ft to the apex of the roof monitor. Compressor-house and plant room, including service pump and ancillary equipment necessary for the water treatment process. The approximate dimensions of the compressor-house are 35ft x 20ft building height 20ft. Single span structure with a curved roof. The roof has three circular metal air vents. The side wall has two windows, the wall that faces the chimney stack has one window, possibly two? The front wall has a door, and an opening, perhaps a window? It may have been possible to gain entry into the compressor-house through the boiler-room. Services from the boiler-house are routed through the compressor-house and exit the building via the side wall. The steam main is supported on steel posts and enters the factory production area through a gap between the receiving sheds. The steam main terminates at dispatching shed number five. The pipe supplying compressed air to the mustard gas discharge system is also visible, "but not on this image." The method of support for the compressed air pipe is similar to that of the steam main. The location of the 24-ton capacity main storage tank for mustard gas is approximately a 130ft south west of the compressor-house. The transfer of mustard gas from a 10-ton railway tank wagon to the main storage tank required a minimum air pressure of 10 lbs. P.S.I. The discharging process took about 90 minutes. There is no obvious sign of an area near the boiler-house used as an open-air coal store. Ideally, a self-draining hard surface is required, for this purpose. The boiler-house was served, by rail. In all probability, the coal was handled, manually from railway truck to the bunkers adjacent to the boilers. For ease of handling, coal may have been, delivered in sacks. '
