Report No. 99027

The oil fired boiler had failed and was urgently needed as the ship was required to manoeuvre. The junior engineer was investigating this fault. While trying to find the fault, the junior engineer tried to ignite the boiler. The burner unit was not secured to the boiler and the combustion chamber had not been purged. Unfortunately, the junior engineer succeeded in his attempt to ignite the boiler and the residual fuel ignited explosively. The force of the explosion detached the burner unit which struck the junior engineer in the chest and face. The flame from the explosion burnt his left hand, wrist and arm and the force of the impact knocked him over backwards, which caused a head wound.

The junior engineer was taken to the ship's hospital for treatment. The boiler was shut down and the fuel valve closed. The burner's forced draught fan was started to purge the furnace. There was an excessive amount of un-burnt fuel in the furnace. The burner unit was not secured to the furnace. The forced draught fan had not been used to purge the furnace. The junior engineer was in a hurry.

No amount of perceived pressure should be allowed to influence safe working practises. The junior probably thought that he was being quick, efficient and helpful. Instead he very nearly delayed the ship, and left her short handed.

Conclusions:

Ø Had the burner been properly secured - the explosion would have been contained.

Ø All of the failures were human.

Ø Ensure that the burner is correctly secured.

Ø Ensure that purging is carried out prior to ignition.

Ø Since all the basic safety precautions and procedures are already in place, it remains only to remind all staff to follow them.
