In June of last year, a fire broke the material storage area of a large cruise ship moored at Yokohama Port, and the Japan Transport Safety Board conducted work using a gas burner while confirmation of safety was insufficient. We have summarized the findings that it is highly possible that high-temperature heat was transferred to the iron wall and the nearby corrugated cardboard ignited.
In June of last year, there was a fire that caused smoke to rise temporarily at the material storage area on the deck of the large cruise ship "Asuka 2" anchored at Yokohama Port, and the Japan Transport Safety Board released an investigation report.
According to this, at that time, around the material storage area, the floor board connected to the iron wall was being cut with a gas burner, and the high temperature heat was transferred to the wall, which ignited the corrugated cardboard nearby and spread it. It is highly likely that it was done.
For work using fire, safety confirmation including the surrounding area was required in the procedure manual specified by the ship, but safety confirmation was insufficient, such as the work supervisor recognized that only the underfloor was the target of confirmation. I point out that.
Also, the sprinklers that were installed arbitrarily were not set to operate the pump automatically, which means that there was not enough water.
After the accident, the ship's operation management company took preventive measures such as training on fire-based work and reviewing the description in the procedure manual.
