Best Practices

  • Ensure the power is off and the equipment is blocked against motion prior to performing maintenance.
  • Devise safe methods to complete tasks involving large objects, massive weights, or where the release of stored energy is a possibility.
  • Provide proper task training.
  • Never use a hydraulic jack as the only tool for supporting large objects, massive weights, or objects that have the potential for the release of stored energy.
  • Avoid metal to metal contact because it slides much easier than wood or other materials against metal.
  • Ensure that all contact areas where jacks or other blocking materials are to be installed are free from grease or other substances to decrease the likelihood of shifting and sliding.
  • Ensure that there is sufficient space around equipment to enable work to be performed safely.
  • Consult and follow the manufacturer's recommended safe work procedures for the maintenance task and monitor work to ensure procedures are followed.
  • Ensure that contractors have safe work procedures in place for the specific task, machine, etc.
  • Before performing any job, consider all hazards and implement formal procedures that address possible hazards.
