Lockout Tagout for Affected Employees
Lockout/tagout is the placement of a lock or tag on an energy isolating device, in accordance with an established procedure, ensuring that the energy isolating device and the equipment being controlled cannot be re-energized until the locking device is removed. While an authorized person usually performs the lockout, an affected employee is any employee that is affected by the lockout/tagout. This course focuses on the general awareness needed for affected employees.

Key Questions
Lockout/tagout (or LOTO) refers to specific practices and procedures to safeguard all workers from the unexpected startup of machinery and equipment or the release of hazardous energy during service or maintenance activities. Lockout/tagout is the placement of a lock or tag on an energy isolating device, in accordance with an established procedure, ensuring that the energy isolating device and the equipment being controlled cannot be re- energized until the locking device is removed.
Who are affected employees in a lockout/tagout?An affected employee is an employee that is affected by the lockout. This commonly includes machine operators who need to know that their machine should not be operating.
What are primary energy sources to be isolated during lockout/tagout?Primary energy sources include electricity, hydraulics (fluids), and pneumatics (air or vacuum energy).
What are secondary (or stored) energy sources to be isolated during lockout/tagout?Secondary energy sources include springs, capacitors, accumulators, counterbalance systems, gravity, and inertia.
Who is an authorized person or employee?An authorized person is the one who performs the lockout. This is someone who is familiar with the equipment and capable of locking it out properly.
What are the 6 steps of an effective energy control program?The six steps to an effective energy control program include:
- Preparation
- Shut down
- Isolation
- Lockout/tagout
- Stored energy check
- Isolation verification
Locks and hasps are used to lockout machinery for energy control.
Sample Video Transcript
“Hazardous energy can take many forms. Consider the simple task of removing a pump and motor unit from a process. Most people would realize that the electricity to the motor needs to be interrupted and locked out before removal, but there is another source of energy that presents a less obvious hazard, and that some people might not think of. The pump is connected to process piping which probably has pressure within it. Before the pump can be removed, workers must be protected by closing valves or inserting blanks to isolate the pump from upstream or downstream fluid pressure and draining the associated piping.”
