10.0 MAINTENANCE

Compressed air can be dangerous if incorrectly handled. Before doing any work on the unit, ensure that all pressure is vented from the system and that the machine cannot be started accidentally.

Ensure that maintenance personnel are adequately trained, competent and have read the Maintenance Manuals.

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 machine cannot be started accidentally or otherwise, by posting warning signs and/or fitting appropriate anti−start devices.

•all residual electrical power sources (mains and battery) are isolated.

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 accidentally or otherwise, by posting warning signs and/or fitting appropriate anti−start devices.

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. pressurized 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.

Upon completion of maintenance tasks and prior to returning the machine into service, ensure that:−

•the machine is suitably tested.

•all guards and safety protection devices are refitted.

•all panels are replaced, canopy and doors closed.

•hazardous materials are effectively contained and disposed of.
