Abstract: On May 25, 2007, an employee, boat service technician, independent contractor, was engaged in the repair of pleasure boats. The employee was alone in the boatyard. A fire developed on the after end of the boat, possibly from a boat battery explosion. The battery was previously removed from the engine compartment and apparently sitting on top of the boat hooked up to a battery charger. The employee was either burned in a flash explosion or enveloped in a fire that moved quickly enough so that he could not escape the flames. The employee sustained serious burns, and he died later at the hospital.
