Employees should use personal protective equipment as well as the proper lockout tagout devices to prevent electrical hazards and keep themselves safe from injury. Aside from PPE like the proper gloves, boots, suits, and more, employees should also use circuit breaker locks, plug locks, and other devices.
Plug locks can prevent specific machines from being plugged into an electric power source. However, electricity can still flow to other machines in the same area. A circuit breaker lockout, however, can shut off electricity in entire areas, thus ensuring that no electronic machines in those areas will be able to run.
