Summary
This safety flash examines failures to verify that electrical equipment is dead at the actual work location rather than only at a remote isolation point. Two examples describe personnel accessing live terminals after selecting the wrong thruster or ROV. It emphasises following proving-dead protocols at the point of work.
Classifications: Electrical safety; electrical hazards.
Classifications: Electrical isolation; electrical lockout.
Classifications: Operating and work procedures.
Classifications: Voltage verification; prove dead; test before touch.
Summary
One of our members discovered that some personnel and worksites were not following the intent of their own company electrical isolation protocols.
