(5) Steam released from safety valves shall, where necessary, be discharged into suitable escape pipes and conveyed to a point of safety.
11 Each steam boiler shall be equipped with an accurate steam pressure gauge suitably located and illuminated. Gauges shall be comparison tested not less frequently than once each six-month period and necessary corrections made. Steam gauges shall be properly connected direct to boiler steam space by a suitable syphon or equivalent device with one but not more than one cock or valve interposed between the gauge and the boiler. The shut-off cock or valve shall be located near the gauge. Gauges and associated parts shall be maintained in good condition for service.
12 (1) Heating and power boilers, other than boilers of the spill-over type, shall be equipped with at least one direct-reading water gauge glass connected direct to boiler. The visible length of the water gauge glass shall not be less than six inches. Water gauge glasses shall be provided with adequate illumination and maintained in clean condition. Tabular gauge glasses shall be provided with suitable safety guards constructed, installed and maintained to permit a clear view of the water level.
(2) Boilers, except those of the spill-over type, shall be equipped with three gauge cocks connected direct to the boiler or to a water column which is connected direct to the boiler and spaced equally within the visible range of the water gauge glass. Gauge cocks shall be adequately illuminated. On boilers where gauge cocks cannot be conveniently located and operated, a second water gauge glass shall be used. When two water gauge glasses are used they shall be located on the same horizontal lines and connected independently direct to the boiler or water column.
(3) The Chief Mechanical Officer of each railway is responsible for the proper and safe positioning of gauge glasses and gauge cocks.
(4) Water gauge glass mountings shall be equipped with independently operated shut-off valves and bottom mounting shall be provided with a drain valve. Similarly, water columns shall be fitted with drain valves. Where shut-offs are used in the connections between a boiler and a water column, or between a boiler and the mounting valves, their full open and closed positions shall be clearly and safely indicated and they shall be locked or sealed in the open position when the boiler is in use.
(5) Gauge glass, gauge cocks, water columns, their associated parts and connections to the boiler shall be maintained free from defects and known to be in good operating condition.
(6) Boilers of the spill-over type not equipped with water glasses or gauge cocks shall be provided with suitable return water flow indicators which shall be adequately illuminated and maintained free from defects.
13 (1) Each heating and power boiler before being put into service and not less frequently than once each 12-month period thereafter shall be subjected to hydrostatic pressure 25 per cent greater than maximum working pressure and all pressure parts and appurtenances shall be carefully examined while under hydrostatic pressure.
(2) Following the pressure test, an internal examination of the boiler shall be made. In order to examine as much of the interior of the boiler as is possible, a sufficient number of inspection plates, manhole covers, handhole covers and washout plugs shall be removed.
(3) Before being returned to service, the boiler and its appurtenances shall be tested under normal steam pressure.
(4) All defects disclosed by any of the above tests and inspections shall be repaired before the boiler is returned to service.
14 Boilers shall be washed out as often as is necessary to maintain them in safe operating condition; a record of each washout shall be kept on file.
