What Is Lockout/Tagout (LOTO)?

LOTO stands for Lockout/Tagout. LOTO procedures exist in the workplace to control hazardous energy and provide effective protection for employees. Without the use of proper lockout/tagout safety procedures, the serviced electrical equipment or machinery can start up without warning or release hazardous energy that could be extremely detrimental to your team.

Lockout/Tagout (LOTO) Procedure by RESA Power

Trust RESA Power to develop your equipment-specific LOTO procedures that are easy to read and maintain.

When Do You Need Lockout/Tagout (LOTO) Procedure?

A comprehensive lockout/tagout (LOTO) procedure is important when performing maintenance or servicing equipment that could potentially cause harm to workers. These procedures ensure that all energy sources are properly shut off and disconnected before any work begins.

Lockout/Tagout (LOTO) procedures are used when:

  • Servicing electrical equipment that does not require power to be ON to perform the Service.
  • Removing or bypassing a machine guard or other safety device where the possibility exists of being injured or caught in moving machinery.
  • Clearing jammed equipment.

RESA Power’s engineers follow the industry standards and OSHA requirements to identify what electrical assets require lockout/tagout and then develop a custom, equipment-specific LOTO procedure. Safety is our #1 priority!

By following LOTO procedures, the risk of injury or death from unexpected startup or release of stored energy is greatly reduced. Lockout/tagout procedures also ensure that equipment is properly isolated and not accidentally turned on while someone is working on it. RESA Power’s engineers carefully develop a safe and reliable Lockout/Tagout (LOTO) procedure for your team that enforces proper equipment shutdown to protect workers from hazardous energy exposure during maintenance or repair services they are performing.

LOTO Procedure for Our Customers

LOTO Procedure for Our Customers

This safety procedure establishes the necessary requirements for the lockout of energy isolation devices whenever maintenance or servicing is done on machines or equipment. It shall be used to ensure that the machine or equipment is stopped, isolated from all potentially hazardous energy sources, and locked out before employees perform any servicing or maintenance where the unexpected energization or start-up of the machine or equipment or release of stored energy could cause injury.

What is the OSHA Standard for Control of Hazardous Energy Sources?

It is essential for companies to have a well-defined and regularly practiced LOTO system in place in order to protect their workers and comply with OSHA regulations. Employers should provide proper lockout/tagout training for employees and make sure they are properly followed at all times.

The OSHA standard for The Control of Hazardous Energy (Lockout/Tagout), Title 29 Code of Federal Regulations (CFR) Part 1910.147, addresses the practices and procedures necessary to disable machinery or equipment, thereby preventing the release of hazardous energy while employees perform servicing and maintenance activities.

The standard outlines measures for controlling hazardous energies—electrical, mechanical, hydraulic, pneumatic, chemical, thermal, and other energy sources.

Hazardous Energy Control


Energy sources including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other sources in machines and equipment can be hazardous to workers. During the servicing and maintenance of machines and equipment, the unexpected startup or release of stored energy can result in serious injury or death to workers. Proper lockout/tagout (LOTO) practices and procedures safeguard workers from the release of hazardous energy.

Why Are Lockout/Tagout Procedures Important?

RESA Power requires our customers to perform all switching and grounding of their own facility equipment. All technicians are instructed to follow our policy, OSHA requirements, and the facility we are always working at LOTO requirements.

LOTO procedures must be implemented at the workplace level and employees must be trained on how to follow the same set of LOTO procedures while coming into direct contact with electrical equipment and machinery. Our safe and reliable Lockout/Tagout (LOTO) procedure is a critical aspect of workplace safety and helps to prevent accidents that might appear at the workplace, including but not limited to

  • Fires and explosions
  • Electrical accidents
  • Chemical exposure
  • Wounds and lacerations

We recommend that the ongoing LOTO training should be an essential part of your company’s safety program.
