TITLE
Fatal 1 - LOTOTO - Failure To Implement Isolation Procedure
COUNTRY OF ORIGIN

WHAT HAPPENED

?

  • Whilst discharging a marine aggregate dredger, a cargo conveyor hopper became blocked with material. 
  • The Discharge Operator started work to clear the blockage without informing the Duty Officer or Duty Engineer (Manager In Charge).
  • The Discharge Operator closed and padlocked the control cab door using a security padlock; but did not isolate energy at source.
  • The Discharge Operator then requested assistance from a co-worker, who was a recently appointed temporary employee.
  • The co-worker asked if the system had been made safe, to which the Discharge Operator replied that it had been.

KEY FINDINGS

  • The Discharge Operator was a long service employee familiar with isolation procedures.
  • The Discharge Operator had placed himself under time pressure as it was approaching the end of the working day. 
  • The newly employed co-worker understood the need for isolation, and was correct to question the isolation status.
  • The Discharge Operator provided a false and invalid isolation assurance to their co-worker.
  • Upon observing the task, the Duty Officer Stepped-in, issued a stop work order and informed the Master and Duty Engineer.
  • The Discharge Operator confirmed that he had not been time pressured by his Manager(s) (Master or Officers) and was unable to account for his non-compliance.
  • Correct procedures were invoked before work resumed.

LEARNING POINTS / ACTIONS TAKEN

HOW COULD THIS HAVE BEEN AVOIDED?

  • The Discharge Operator’s breach of isolation requirements was addressed through disciplinary procedures and they no longer work for the company.
  • The co-worker received further training in LOTOTO procedures, inc. manager-in-charge / one-person-one lock requirements etc; following exposure to non-compliant isolation procedures.

KEY REVIEW POINTS

  • The Manager-in-Charge requirement overseeing isolations is critical to the process, ensuring machinery is correctly and effectively isolated.
  • Experienced employees must set an exemplary standard to less experienced or newly employed personnel.
  • Security locks must never be used for isolation, there may be more than one key in circulation, or be a combination padlock.
  • The Duty Officer was effective in monitoring activity on board, and pro-actively stepped-in to halt hazardous circumstances.
