The Ultimate Guide to Lockout Tagout (LOTO) Devices: Safety, Standards & Best Practices

Ensuring the safety of workers during maintenance and servicing of machinery is a critical aspect of any industrial operation. Lockout Tagout (LOTO) is a well-established procedure designed to prevent accidental energy release and protect employees from harm. This comprehensive guide will walk you through everything you need to know about LOTO devices, their importance, and how to implement them effectively in your workplace.

What are Lockout Tagout Devices and Their Importance?

Lockout Tagout (LOTO) devices are safety mechanisms used to isolate hazardous energy sources in machinery and equipment during maintenance or repair. They play a vital role in preventing the accidental startup of machinery or the release of stored energy, which can lead to severe injuries or fatalities.

The importance of LOTO devices lies in their ability to:

  • Enhance worker safety: By ensuring machines remain de-energized, LOTO devices protect workers from unexpected hazards.
  • Ensure regulatory compliance: Adhering to LOTO procedures is a legal requirement under OSHA regulations, helping organizations avoid penalties and maintain safe working conditions.
  • Promote operational efficiency: Proper use of LOTO devices minimizes downtime and enhances the safety culture within an organization.

Difference Between Lockout and Tagout

Lockout and Tagout are two methods used to control hazardous energy. Here’s how they differ:

  • Lockout: This method involves physically locking a device to an energy-isolating mechanism, such as a valve or switch. The lockout device, often a padlock, ensures that the machinery cannot be activated until the lock is removed by the person who applied it.
  • Tagout: This method uses tags to warn personnel that the equipment is isolated and should not be operated. Unlike lockout, tagout does not provide a physical barrier to energizing the equipment but serves as a warning indicator.

While both methods aim to prevent accidental startup, lockout is generally more secure because it physically restrains the equipment from being powered on.

Lockout Tagout and Machine Guarding

Machine Guarding and LOTO are complementary safety measures that serve different purposes:

  • Machine Guarding: Involves the use of physical barriers or shields to protect workers from moving parts and other operational hazards during the normal functioning of machinery.
  • LOTO: Ensures that machinery is completely de-energized and incapable of accidental startup during maintenance or servicing.

Together, these safety practices provide comprehensive protection, addressing both operational safety (machine guarding) and maintenance safety (LOTO).

OSHA Lockout Tagout Standard

The Occupational Safety and Health Administration (OSHA) regulates LOTO practices under the 29 CFR 1910.147 standard. This standard specifies the requirements for controlling hazardous energy during the servicing and maintenance of machines and equipment. Key points of the standard include:

  • Establishing an energy control program: Employers must develop and document procedures to isolate and control hazardous energy.
  • Training employees: All employees involved in LOTO must receive proper training on their roles and responsibilities.
  • Conducting periodic inspections: Regular inspections are required to ensure compliance and effectiveness of the LOTO procedures.

OSHA Lockout/Tagout Exceptions

OSHA provides certain exceptions to the LOTO requirement under specific conditions. These include:

  • Cord and plug connected equipment: When equipment is unplugged and the plug remains under the exclusive control of the employee performing the service.
  • Minor servicing activities: Such as minor tool changes and adjustments that are routine, repetitive, and integral to the use of the equipment, provided they do not pose significant risk.
  • Hot tap operations: Involving work on pressurized pipelines where shutdown is impractical and the employer demonstrates that continuity of service is essential, and other effective safety measures are in place.

OSHA Lockout/Tagout Violations

Violations of OSHA’s LOTO standards can result in significant penalties and increased risk of accidents. Common violations include:

  • Lack of a documented energy control program: Failing to have written procedures for controlling hazardous energy.
  • Inadequate employee training: Not providing sufficient training for employees on LOTO practices.
  • Failure to conduct periodic inspections: Neglecting to regularly inspect and verify the effectiveness of LOTO procedures.

  • Circuit breaker lockouts: Prevent circuit breakers from being switched on, isolating electrical energy.
  • Plug lockouts: Secure electrical plugs, preventing them from being connected to power sources.

What is an Energy Isolating Device?

An energy isolating device is a mechanical device that physically prevents the transmission or release of energy. Examples include:

  • Manually operated disconnect switches: Cut off electrical power supply.
  • Slide gates and slip blinds: Block the flow of materials in pipelines.
  • Line valves: Control the flow of liquids or gases in a system.

These devices are crucial in the lockout process as they ensure hazardous energy is effectively isolated.

What is a Lockout Device?

A lockout device is a tool that locks the energy isolating device in a safe position, preventing it from being operated. Lockout devices are essential for ensuring that equipment remains de-energized until maintenance is complete and the device is safely removed by authorized personnel.

Padlocks

Padlocks are the most common type of lockout device. Each padlock should be uniquely keyed and dedicated solely for lockout purposes. The key to a padlock should be kept only by the person who applied the lock, ensuring that it can only be removed by the individual who placed it.

What is a Tagout Device?

A tagout device is a prominent warning tag attached to the energy isolating device, alerting others not to operate the equipment.
