The victim sustained burns on his face, neck and hands due to radiant heat. He was given first aid and signed off from the vessel for further medical attention ashore. The investigation found that he had attempted to check the voltage across breaker terminals with the multimeter selector knob at the Resistance (1 Ohm) setting instead of the Voltage (1000VAC) setting. The electric charge found its shortest path (through the multimeter), which then exploded. It was also found that the victim had failed to use insulating gloves which would have decreased the severity of the injury.
