Key Concepts

-
Electrical Isolation
Electrical isolation involves disconnecting equipment from its energy source to ensure that no hazardous voltage is present during work. This procedure minimizes the risk of electrical shock or other dangers associated with contact with live circuits.
Lockout/Tagout Procedures
Lockout/Tagout procedures are safety protocols used to secure isolated equipment, preventing accidental re-energization during maintenance or repair work. This process ensures that once a circuit is deactivated, it remains so until the work is complete, significantly reducing the potential for accidents.
