Maintenance was being carried out on a fresh water generator situated in the engine room. The day shift started the work on the generator, cleaning the condenser plates but did not complete the task and handed it over to nightshift. A toolbox talk took place between the nightshift and dayshift maintenance crew.

The injured person (IP) completed a permit to work, in order to continue the maintenance on the fresh water generator while the isolation certificate remained in place. The Mechanic de-isolated the generator in order to function the system, with the assistance of the Senior Mechanic.
