What Is Lockout Tagout?

Safety management in the workplace is a critical aspect of any successful business. It involves creating, implementing, and overseeing policies and procedures to ensure a safe working environment. This goes beyond simply preventing accidents – it also includes protecting employee health, improving productivity, and fostering a safety culture.

In many industries, such as manufacturing, construction, and energy, safety management is especially critical due to the high-risk nature of the work. These industries often involve heavy machinery, hazardous materials, and complex processes that can pose significant risks if not managed properly.

Safety management is not a one-size-fits-all approach. Different workplaces have different hazards, and successful safety management must be tailored to address these specific risks. One common and effective safety practice is the lockout tagout system.

Defining Lockout Tagout: What is Lockout Tagout?

Lockout Tagout, often abbreviated as LOTO, is a safety procedure used in industry and research settings to ensure that dangerous machines are properly shut off and cannot be started again before maintenance or repair work is completed. The term “lockout” refers to using a lock to hold an energy-isolating device in a safe position and prevent the energization of a machine or equipment. The term “tagout” is a label placed on a locked device to indicate that it should not be operated until the tag is removed.

Lockout tagout procedures are outlined in the Occupational Safety and Health Administration (OSHA) standard for controlling hazardous energy. This standard, 1910.147, outlines the minimum performance requirements for controlling hazardous energy during servicing and maintenance of machines and equipment.

The Importance of Lockout Tagout in Safety Management

The primary goal of lockout tagout is to prevent the unexpected start-up of machinery or equipment, which can lead to serious accidents and injuries. According to OSHA, compliance with the lockout tagout standard prevents an estimated 120 fatalities and 50,000 injuries annually.

Furthermore, lockout tagout procedures help to ensure that employees are protected while performing maintenance or service work on machinery or equipment. By controlling hazardous energy, these procedures reduce the risk of electrical shock, burns, crushing injuries, cuts, and amputations.

The benefits of lockout tagout also extend beyond safety. These procedures can also improve productivity and reduce equipment downtime by preventing unexpected machine start-ups. They can also help protect machinery and equipment from damage, reducing maintenance costs and prolonging equipment life.

Key Components of a Lockout Tagout System

A successful lockout tagout system consists of several key components. The first is a comprehensive energy control program. This includes procedures for shutting down, isolating, blocking, and securing machines or equipment to control hazardous energy.

Another key component is the use of lockout and tagout devices. These devices, which include locks, tags, chains, wedges, key blocks, adapter pins, self-locking fasteners, and other hardware, are used to hold energy-isolating devices in a safe or “off” position. Training is also a crucial part of a lockout tagout system. Employees must be trained to understand the purpose and function of the energy control program and have the knowledge and skills required to apply, use, and remove energy controls safely.

How Does Lockout Tagout Work?

The lockout tagout process typically involves several steps. The first is to prepare for shutdown. This involves identifying the energy source(s), understanding the type and magnitude of the energy, and knowing the methods or means to control the energy.

The next step is to shut down the equipment. This should be done orderly, predictable, and safely to avoid additional or increased employee hazards due to the equipment stoppage. Once the equipment is shut down, the energy-isolating devices must be activated to isolate the equipment from the energy source(s). The locking and tagging of the devices can then be performed. This is typically done by authorized employees performing the servicing or maintenance work.

Before starting work, it’s important to ensure no personnel are exposed and verify the equipment’s isolation. This typically involves testing the equipment to make sure it will not operate. The equipment can be restored to normal operations once the servicing or maintenance work is complete. The lockout or tagout devices are removed, and the energy-isolating devices are deactivated.

Implementing Lockout Tagout in the Workplace

Implementing a lockout tagout system in the workplace requires careful planning and execution. It begins with developing and documenting an energy control program. This program should outline the procedures for shutting down, isolating, blocking, and securing machines or equipment to control hazardous energy.

Next, lockout and tagout devices must be provided. These devices must be singularly identifiable, durable, standardized, and substantial. They must also indicate the identity of the employee applying the device.

Training is another crucial part of implementing a lockout tagout system. Employees must be trained to understand the purpose and function of the energy control program and have the knowledge and skills required to apply, use, and remove energy controls safely. Procedures should also be implemented for inspecting the energy control program to meet the standard’s requirements. This includes conducting periodic inspections of energy control procedures and providing feedback to employees on their performance.

Lockout Tagout Training and Certification

There are many resources available for lockout tagout training and certification. OSHA offers a variety of training resources, including online courses, onsite training, and training materials. Training typically covers a range of topics, including the recognition of applicable hazardous energy sources, the type and magnitude of the energy found in the workplace, and the methods. It is necessary for energy isolation and control.

OSHA does not require certification, but it can benefit professionals in the field. Several organizations offer certification programs that can validate an individual’s knowledge and skills in lockout tagout procedures.

Common Misconceptions about Lockout Tagout

There are several common misconceptions about lockout tagout. One is that lockout tagout procedures are only necessary for large industrial machines. In reality, any device that stores energy – including small, portable equipment – can pose a risk and should be included in a lockout tagout program.

Another misconception is that lockout tagout procedures are too time-consuming and disrupt productivity. While it’s true that these procedures can take some time, the alternative – a serious accident or injury – can result in much greater downtime and loss of productivity. A third common misconception is that lockout tagout is the sole responsibility of maintenance workers or safety specialists. In reality, everyone in the workplace has a role in safety, and all employees should be trained on lockout tagout procedures.

The Consequences of Not Using Lockout Tagout

The consequences of not using lockout tagout can be severe. In addition to the risk of serious accidents and injuries, failure to comply with OSHA’s lockout tagout standard can result in hefty fines. Moreover, accidents resulting from the failure to control hazardous energy can increase workers’ compensation costs, lost productivity, and damage to machinery and equipment. They can also damage a company’s reputation and decrease employee morale.

Conclusion: The Lasting Impact of Lockout Tagout on Safety Management

In conclusion, lockout tagout is a crucial part of safety management. By controlling hazardous energy, these procedures can prevent serious accidents and injuries, improve productivity, reduce maintenance costs, and foster a safety culture.

Implementing a successful lockout tagout program requires careful planning and execution, as well as ongoing training and inspection. Despite common misconceptions, these procedures are not overly time-consuming or disruptive and are not the sole responsibility of maintenance workers or safety specialists. Rather, they are a shared responsibility that benefits everyone in the workplace.
