Even after lockout, electrical potential may exist in some equipment, typically capacitors. Such potential energy could result in severe burns or death if improperly dissipated.
To ensure safe conditions for maintenance, the stored electrical energy must be dissipated. This may require a defined waiting period that is sufficient to complete the dissipation, or there may be specific plant requirements. In many cases testing is required to ensure zero potential.
Information covering sources of electrical energy is available on the Electrical Energy Sources page.
Proper lockout/tagout can virtually eliminate the risk involved with hazardous energy.
