5. Gebrauchsanweisung (Bedienung)

Follow these general steps for applying the Master Lock S430 lockout hasp as part of a standard Lockout/Tagout procedure. Always refer to your organization's specific LOTO policy.

1. Preparation for Shutdown: Identify all energy sources and potential hazards associated with the equipment. Notify all affected personnel.
2. Equipment Shutdown: Turn off or shut down the equipment using normal operating procedures.
3. Isolation of System from Hazardous Energy: Disconnect or de-energize the equipment from its energy source(s). This may involve turning off circuit breakers, closing valves, or blocking moving parts.
4. Application of Lockout/Tagout Devices:
   • Place the Master Lock S430 hasp over the energy isolating device (e.g., circuit breaker handle, valve handle).
   • Ensure the hasp fully encompasses the device, preventing its operation.
   • Each authorized employee involved in the work should then attach their personal safety padlock through one of the holes on the hasp. The S430 can accommodate up to two padlocks.
   • Attach a lockout tag to the hasp or padlock, providing information such as the name of the person who applied the lock, the date, and the reason for the lockout.
5. Dissipation of Residual or Stored Energy: Safely release or restrain any stored energy (e.g., springs, hydraulic pressure, capacitors).
6. Verification of Isolation: Attempt to operate the equipment to confirm that it cannot be started and that all energy sources are effectively isolated. Return controls to the "off" position after verification.
7. Performing Service/Maintenance: Proceed with the necessary work.
8. Removal of Lockout/Tagout Devices: Once work is complete and the equipment is safe to operate, remove lockout devices in reverse order of application, ensuring all personnel are clear.

  • If the lockout point is too large, a different size hasp or lockout device may be required.
• Padlock does not fit through the hasp:
  • Verify that the padlock shackle diameter is compatible with the holes on the S430 hasp.
  • Use Master Lock safety padlocks designed for lockout/tagout applications, which are typically compatible.
• Hasp appears damaged or compromised:
  • Do not use a damaged hasp. Immediately remove it from service and replace it with a new, undamaged unit.
