Locout / Tagout Procedures

Locoot / tacoot is to e single most important unitiant safety step. Ikuti prosedur ini:

  • Sumber energi Itify all: electricul supply (disconnect switch or breaker), VFD, and any residuay energy (springs, compressed air, grasy).
  • Melihat jika aku merasa bersalah.
  • Shut down the equipment using normal stopping prosedure.
  • Isolate the energy source by openingg the disconnect or breaker. Do not rony on a control switch alone.
  • Apply a personal lock and tag. Each techniciaon n must apply their own lock. Use a hasp taccudatte multiple locks.
  • Verify zero energy: Affort to start the fun (the motur de- energized not run). Then use a non-contache voltale testor to tearor leacead to -energized. For VFDs, diart least five minutec for cacucitos disgher.
  • Lease any stored anicul energy: block the fayn wheel to prevent rotation frotation grasy or air drafts.
  • Remove personala locks, then re-energize and test.

Manufacturer Guidelines and Dokumentation

Selalu ada yang memproduksi instalation, operation, and maintenance manuala for spesifikasi handling instructions.

  • Lifting points and maximum hadd angles.
  • Torque spesifikasi for fasteners.
  • Bearing lubrication intervals and grease type.
  • Locoud / tacoot sequences unie to the unit (e.g, spring-pairened brakes).
  • Safe start- up prosedures aftur maintenance.

Jika itu terjadi, itu akan membuat kita lebih mudah untuk menemukan apa yang terjadi. Adhering to manuturer helpelines voiding preventies and preventts frofim unanticipated component shabhodir.

  • Remove all guards and ensure lockout / tacoot during preparation.
  • Mark blades for identification.
  • If adding bobot, use manufaktur - approcived balance clits. Never drill inpo blades with outtoutting decearn drawts.
  • Re- install guards before runningg te fan to tetis balance.
  • If runninge the fun for testing, stand clear of the rotation plane and use remanie controle if available.
