What should be done with power lines to electrical outlets before starting work?

Before starting any work related to asbestos or similar hazardous materials, it is crucial to turn off and lock down power lines to electrical outlets. This action ensures that there is no risk of electrical shock or accidental power activation while workers are engaged in the process. Locking down the power lines is a safety protocol that prevents anyone from accidentally turning the power back on while work is in progress, which could lead to serious accidents or injuries.

Turning off the power is a fundamental aspect of creating a safe work environment, particularly in the context of asbestos work, where the presence of airborne fibers presents additional risks. By securing the power lines, workers can focus on their tasks without the concern of electrical hazards, thereby promoting a safer and more controlled working atmosphere.

Covering power lines with plastic or leaving them as is does not eliminate the risk of electrical shock and does not provide the same level of assurance. Disconnecting them could be appropriate but may not always be needed if the primary action of turning off and locking down is effective. Therefore, turning off and locking down is the recommended procedure before commencing work.
