door nuts and break the joint before removing the dogs and knocking in the doors. The top access door should be knocked in first with the dogs slacked back but not removed. The access door should be held by a rope or other means when the dogs are removed. When the top access door has been removed, the bottom access door may be knocked in.
Seafarers should:
       stand clear of hot vapours when doors are opened, and
       not enter any boiler, boiler furnaces or boiler flue until it has cooled sufficiently to make work in such places safe.
Work should not be undertaken while a second boiler is in operation, or when this is not possible, there are at least two valves providing isolation between the fired boiler and the boiler being inspected.
Spaces at the top and sides of boilers should not be used for storage.
Safety valves should be properly sealed and maintained in good operational condition at all times. Special care should be taken to maintain water gauges in proper order. They should be checked and blown through in a proper manner by a competent person at frequent intervals. Only a competent person should replace gauges.
The water level should be checked at all times when fires are alight. Should the water level fall below the glass, the boiler should be immediately secured as required.
When bringing a boiler back into service, ensure that:
       the combustion chambers have been properly purged free of gas and that no loose oil has accumulated on the furnace floor
       all burners are clean and properly assembled
       the fuel oil has been recirculated until all parts of the system have reached a suitable temperature before admission to the furnace
       when lighting up a boiler, all persons are standing clear of any openings to avoid injury from a possible blowback.
Should a furnace fail to light for any reason when the oil valve is opened:
       the valve should be closed;
       the combustion chamber should be properly purged.
Seafarers cleaning tubes, scaling boilers and cleaning back-ends should wear appropriate PPE including respirators. Before using any chemicals for this work, ensure the SDS for the chemical is checked and that suitable control measures are implemented (refer to section 13).
The escape routes from the boiler fronts and firing spaces must be kept clear.
Where required to be fitted, the gauge glass cover should always be in place when the glass is under pressure. If a gauge glass or cover needs to be replaced or repaired, the gauge should be shut off and drained before the cover is removed.
The same isolating and maintenance principles should be applied
