LTI: Engineer injured following engine room slip/trip

The incident occurred during a dry dock, when an engineer was walking in the engine room searching for a tool and he stepped on a loose floor plate.

The floor plate was not bolted down and slipped sideways.  As the plate moved, his leg started falling to the bilge well below, and the opposite end of the plate flipped upwards and struck his abdomen. 

He sustained a large laceration to his abdomen which was attended to in the local hospital and required seven days off work to recover.

There had been a recent overhaul of diesel generators; when completed, floor plates removed to facilitate that overhaul had been replaced but were not screwed down.

Contributing causes identified were:

• No stopping mechanisms were fitted on the supporting frames/bars of the plates in order to stop these plates from sliding to the side. One particular plate was bent upwards at one corner and was able to slide freely if not bolted down.
  
  
• An existing unsafe condition (the loose floor plate) had been spotted but had not been reported or addressed.
  
  
• The permit to work (PTW) closure protocol following the earlier generator maintenance was not followed. No check had been made that the worksite had been returned to safe condition;

Root cause analysis identified that standards, policies and administrative controls were not used effectively – enforcement was not adequate.

• Procedures and overall ethos for safety during the dry dock was not adequate. There had been a failure to properly implement safety in shipyard procedures/guidelines:
  
  
  • The shipyard safety bridging document had been signed, but was not properly completed and did not effectively bridge between vessel and shipyard safety systems.
    
    
  • There had been daily morning meetings of supervisors of all parties in attendance, but these meetings had discontinued a week prior to the incident.
    
    
• On a day-to-day level, there were gaps in enforcement of the following procedures:
  
  
  • job safety analysis (JSA) and task planning
    
    
  • personal protective equipment (PPE) – the injured person was wearing a light t-shirt instead of a full coverall which contributed to the severity of the injury
    
    
  • hazard observation – the hazard posed by the existing arrangements of the flooring plates in the engine room had not been properly identified
    
    
  • managing contractors and third-parties – successful integration and supervision of sub-contractor workforce was not applied despite procedures being in place. This led to a loss of control and safety oversight of their activities to some extent as well as a diminishing of the safety culture.
