3 Types of Employees To Train for Lockout Tagout - LOTO Training

Employees handling machinery maintenance and servicing must receive lockout tagout training. This is to protect them from injuries that can happen due to an equipment’s unexpected startup or stored hazardous energy release. The lockout tagout standard of the Occupational Safety and Health Administration (OSHA) requires that organizations and facilities adopt and implement the following procedures with regard to equipment:

  • Shutting it down

  • Isolating it from its energy source

  • Preventing the release of hazardous energy while performing maintenance and servicing

You can refer to OSHA’s standard for minimum requirements and comprehensive criteria to help you establish a lockout tagout safety program specific to your requirements.

Who Needs LOTO Training?

All employees shall be instructed about the requirements and procedures of the lockout tagout safety program regardless of their position or assignment.

Authorized Employee

A lockout tagout authorized employee has been given the responsibility, training, and authority to implement lockout tagout procedures on particular equipment. He or she must be certified by his or her supervisor on each piece of equipment to demonstrate his or her thorough understanding of the lockout tagout safety procedures. His or her responsibilities include:

  1. Completing all the training required to become authorized to perform lockout tagout on a specific machine, tool, or equipment

  2. Performing lockout tagout that conforms to the company’s program

  3. Retaining hazardous energy control of the machine or equipment while servicing it and LOTO is in progress

  4. Working only under his or her own lock and tag

  5. Maintaining lockout tagout devices in good and working conditions

Affected Employee

A lockout tagout affected employee is someone who works with a machine covered by the lockout tagout safety standard. He or she is at risk of being harmed by a machine requiring lockout tagout.

Although affected employees are not authorized to apply or remove lockout tagout devices, they must understand the procedures so that they can monitor whether there are violations when it comes to applying the lockout tagout procedure.

Other Employee

He or she is someone who is working in an area where a particular LOTO procedure is used. Like affected employees, other employees cannot put or remove lockout tagout devices.

Employee Training

All affected, authorized, and other employees must be trained as required by 1910.332 and 1919.147(c). Other OSHA lockout tagout training requirements must be customized to a workplace’s needs.

Authorized Employees

The employer must either develop and provide lockout tagout training or outsource this from independent lockout tagout training providers. Either way, the following must be considered:

  1. The applicable hazardous energy sources

  2. Magnitude and type of energy in the workplace

  3. Means and methods for energy control and isolation

  4. Removal of devices that control hazardous energy

When it comes to LOTO, the supervisors of the authorized employees must ensure that the employees are certified and that training has taken place. A supervisor’s responsibilities include:

  • Creating equipment-specific LOTO procedures

  • Maintaining a list of authorized workers

  • Provide lockout tagout safety guidelines if requested

They must also provide the equipment that the authorized employees need for the equipment-specific LOTO training. The authorized employee will be presented with equipment-specific written procedures to verify their understanding of the procedure so that they perform it accordingly.

Outside Personnel

If outside contractors are hired to repair equipment where LOTO is required, the authorized employee will be the one to inform them of the energy control procedures for a particular machine. If needed, he or she will assist the contractors in locking out the machine or equipment.

Group Lockout

If a group of employees is tasked to repair a machine, each employee will put his or her personal tag or lock on the group lockout device as soon as he or she begins to work. He or she will remove this device once the work on the machine has been completed.

On the other hand, if there is more than one authorized employee required to lock or tag out a machine, there should be a primary authorized employee to:

  1. Coordinate and implement the LOTO of hazardous energy sources and the particular machine to be serviced

  2. Coordinate with the machine operators pre- and post-servicing on tasks that need LOTO

  3. Lead a group of servicing or maintenance employees

  4. Maintain accountability of each authorized employee under his or her group

Affected and Other Employees

They are given LOTO training so that they are aware of the restrictions and can identify locks and tags. Here, they will be instructed never to reenergize or restart a locked-out or tagged-out machine. They will also be retrained if there is a change in OSHA regulation or their employer’s guidelines. This retraining can be done through awareness campaigns.


Retraining is required when:
  1. A job assignment change involving the use of different LOTO procedures
  2. A change in processes, machines, or equipment that presents new hazards
  3. A change in the procedures for energy control
  4. Any reason to believe that an employee needs more knowledge on the energy control procedures
  5. An employee deviating from the established procedures
How knowledgeable are your employees with regard to the existing LOTO procedures in your workplace? You can use the following checklist for your reference:
