Support Raised Machinery with Rated Equipment
A hydraulic jack is a lifting tool, not a support. The Health and Safety Authority advises that raised machinery must be secured on suitable axle stands or solid blocks before anyone works beneath it. Park on firm, level ground, prevent movement, isolate the engine and lower attachments where possible. Use lifting points specified by the manufacturer and equipment rated for the load; improvised timber, a bucket or a hydraulic cylinder should not be treated as a dependable substitute for a mechanical support.
Treat Hydraulic Pressure as a Serious Hazard
Hydraulic systems store energy even when a machine is switched off. A pinhole leak can inject fluid through skin and requires urgent medical assessment, so never search for leaks with a hand. Use appropriate methods and protective equipment, release pressure according to the manual and replace damaged hoses rather than patching them. Keep people clear of raised attachments and never work underneath an unsupported loader or implement.
Check Lifting Equipment and Workshop Records
HSA machinery guidance says hydraulic lifting equipment with a capacity greater than 1,000 kg should have check valves or another suitable device to prevent uncontrolled descent. Farm workshop air compressors also need attention: HSA guidance specifies examination by a competent person at least every 24 months. These requirements do not replace the manufacturer’s instructions or a risk assessment for the particular workshop. Consult the HSA’s farm machinery safety guidance and its tractor and machinery guide.
Stop When the Load or Support Is Uncertain
Keep a written inspection record for lifting equipment and remove damaged supports, chains or hoses from service. If a lift is unstable, the load rating is uncertain or the job requires entering a crush zone, stop and get competent help. A few extra minutes spent setting up supports are insignificant beside the consequences of a machine shifting unexpectedly.
