Prior to attempting any maintenance work, ensure that:-
•
all air pressure is fully discharged and isolated from the system. If the automatic
blowdown valve is used for this purpose, then allow enough time for it to complete
the operation.
•
the discharge pipe / manifold area is depressurised by opening the discharge valve,
while keeping clear of any airflow from it.
WARNING
!
Pressure will remain in the system between the minimum pressure valve
and the service valve after shutdown and operation of the auto blowdown
valve.
This pressure must be relieved by :
(a) Disconnecting any downstream equipment.
(b) Opening the discharge valve to atmosphere.
•
the machine cannot be started. Post warning signs and/or fit anti-start devices.
•
Disconnect battery cables.
Prior to opening or removing panels or covers to work inside a machine,
ensure that:-
•
anyone entering the machine is aware of the reduced level of protection and the
additional hazards, including hot surfaces and intermittently moving parts.
•
The machine cannot be started.
Prior to attempting any maintenance work on a running machine, ensure that:-
•
the work carried out is limited to only those tasks which require the machine to run.
•
the work carried out with safety protection devices disabled or removed is limited to
only those tasks which require the machine to be running with safety protection
devices disabled or removed.
•
all hazards present are known (e.g. pressurised components, electrically live
components, removed panels, covers and guards, extreme temperatures, inflow and
outflow of air, intermittently moving parts, safety valve discharge etc.).
•
appropriate personal protective equipment is worn.
•
loose clothing, jewelry, long hair etc. is made safe.
•
warning signs indicating that Maintenance Work is in Progress are posted in a
position that can be clearly seen.
