What must each crew do when two or more independent crews work on the same lines or equipment?

The correct response emphasizes the crucial nature of safety procedures when multiple independent crews are working on the same lines or equipment. Each crew must independently comply with the same lockout/tagout and de-energizing procedures to ensure that all safety protocols are followed consistently and effectively. This compliance is critical for preventing accidents and ensuring that everyone is protected from the risks associated with working on energized equipment.

Lockout/tagout procedures are designed to guarantee that machines and energy sources are properly shut off and not able to be started again until maintenance work is completed. When several crews are involved, it's imperative that each team adheres to these protocols, as relying on only one crew’s procedures could lead to misunderstandings and potentially dangerous situations. Independent compliance helps maintain a high standard of safety across all teams, ensuring that everyone involved is aware of and follows the same steps to avoid any risk of injury.
