Summary
During contractor equipment demobilisation aboard a vessel, removal of lockout/tagout re-energised a disconnected cable at 440 volts. Its ends touched the chassis and arced near an employee’s hand; nobody was injured. The flash identifies communication, permit, isolation verification, multiple-key lockout, breaker labelling and electrical drawing deficiencies.

Summary
A cable believed isolated became live at 440 volts after lockout controls were removed, narrowly avoiding contact and an arc injury.
