- Lafarge Canada Inc. hires contract workers every year as part of an extensive preventative maintenance activity to manually clean electrostatic precipitators (ESPs) at its Bath plant. The ESPs are divided into two sections, North and South, and the power supply to them is normally disconnected and locked out of service in order to protect the contract workers from electric shock.
- A worker was assigned to clean insulators in the North ESP section and the power supply to the North ESPs had been de-energized, locked out of service and tagged; however, the power supply to the South ESP section had not.
- To clean an insulator, the worker opened an access panel to a section of the ESP that happened to energize both the North and South sides. The worker received an electrical shock and fell to the ground. The worker was able to speak to other workers, was taken to hospital for treatment and released.
