Application of Energy Control Devices

Basic Steps in Controlling Energy

To safely apply energy controls to machines or equipment (using either lockout or tagout devices), authorized workers must perform lockout/tagout procedures in the following specific order:

LOTO follows an equipment-specific procedure.
  1. notify all affected employees of the requirement for lockout/tagout;
  2. identify all energy sources;
  3. de-energize equipment by isolating or blocking the energy sources;
  4. dissipate the potential (stored) energy that could affect the equipment (such as capacitors);
  5. lock out the equipment's energy-isolating devices (switches, valves, etc); and/or
  6. tag out the equipment's energy-isolating devices if you can't lock them out.
