What safety procedure should be implemented before working on electrical systems?

The implementation of lockout/tagout procedures is crucial before working on electrical systems because it ensures that all sources of energy, including electrical, are properly isolated and cannot be inadvertently energized while work is being performed. This procedure involves placing a physical lock and a tag on the energy isolating device, effectively communicating to others that maintenance or repair is taking place and that they should not attempt to operate the equipment or circuit.

Lockout/tagout practices are designed to prevent accidental startup of machinery and provide a safe working environment, significantly reducing the risk of electrical shock or injury. This practice is not only a standard safety protocol but also often mandated by regulatory agencies, emphasizing its importance in ensuring worker safety.

While using insulated gloves, checking for proper lighting, and informing coworkers are all important safety measures to consider in a workplace, none of these actions alone provide the same level of protection and systematic approach to energy control that lockout/tagout procedures offer. Therefore, adhering to lockout/tagout procedures is the best practice for ensuring safety before engaging with electrical systems.
