3 SAFETY
3.1 General - Operations
Only authorised people and qualified personnel should work on the system, and take suitable
precautions to prevent any potential injuries. Always adhere to authorised working practices, and
use the correct tools for the job. To facilitate this, make sure that these are available before
commencing the test.
Ensure that the working area is kept clear and uncluttered.
3.2 General - Hydraulic
Do not work on pressurised systems. Hydraulic systems contain a large amount of stored energy
when pressurised, therefore the system (including any accumulators) should be de-pressurised,
and the power pack switched off, prior to working on the system. Exceptions to this would be
system adjustments to components requiring the presence of pressure and/or flow.
Any personnel authorised to work on the system must have a complete understanding of the
operation of the hydraulic system, so that they will be aware of any system liable to remain
pressurised or hazardous in any other way. Ensure that all personnel are clear of any
mechanical/hydraulic system likely to move if pressure to system actuators is released or applied.
Do not attempt to tighten any leaking fittings whilst under pressure. A hose/fitting rupture could
result, leading to injury from flying components and/or oil jets.
Regularly inspect fittings and pipe-work for mechanical damage. If any such damage is found, the
item must be repaired or replaced as necessary before pressure is applied to the system. Do not
allow damaged fittings to remain in service.
Take care when inspecting, commissioning, repairing or maintaining the system to avoid jets of oil
issuing from open orifices; pipe ends etc. if pressure is applied. Particular care should be taken to
protect the eyes.
Hydraulic components may be heavy and slippery when covered in oil. Ensure that adequate
protective clothing and footwear is used.
Any moving component should be treated with caution when the system is pressurised during
operation, and especially during on-deck testing and repair. Keep clear of all moving components,
and take all necessary precautions to avoid injury when working on these systems by preventing
movement of any components likely to cause injury.
3.3 General - Mechanical
Ensure that all the relevant guards are in place before applying power to the system. The power
must be turned off and any potential movement prevented before removal of any guard.
Beware of and keep clear of all moving components. Do not work on the system whilst power is
applied, or if there is any potential for components to move.
Ensure that all load bearing components are adequately and regularly inspected. If damage is
found the component must be repaired/replaced as necessary. Do not allow damaged components
to remain in service.
