Adjust these devices to stop the energy flow of the device
PPE may be required
Common energy isolation techniques: close the valve and open the circuit breaker
All operational controllers must be turned off or returned to neutral by authorized personnel. Energy isolators must be used to prevent others from unintentionally opening valves, triggering switches, or performing other operations on equipment/systems.
Energy isolation requires that switches, valves and other controls be in separate or closed positions.
