Why LOTO Devices Matter

They are more than just compliance tools—they are essential safeguards that protect workers from life-threatening injuries. By physically isolating energy sources, these lockout tagout devices eliminate the risk of accidental startup during servicing. They also ensure compliance with OSHA and NFPA 70E standards, helping employers avoid costly fines and liability. Beyond safety, effective lockout tagout practices reduce equipment downtime, minimize accidents, and build a culture of trust where employees know their well-being is prioritized.

Training and Compliance

Workers can gain essential skills through OSHA Lockout Tagout Training, designed to meet federal safety expectations. Proper training ensures that employees understand how to select and apply LOTO devices, recognize hazardous energy sources, and follow OSHA and NFPA 70E requirements. Training also helps employers maintain compliance, reduce the risk of costly violations, and foster a safer and more efficient workplace.

They are essential for controlling hazardous energy during the maintenance or servicing of machines and equipment. These devices are applied to energy-isolating devices—such as disconnect switches, valves, or plugs—to ensure that machinery cannot be inadvertently energized, preventing serious injuries or fatalities. Understanding the various types of devices, their applications, and OSHA requirements is crucial for developing a compliant and effective LOTO program. If you’re new to the concept, see What is Lockout Tagout? to understand the fundamentals and how they apply in industry.

To meet the requirements outlined in CFR 1910.147, employers must implement lockout tagout practices using devices that prevent the unexpected startup of machines during servicing. This includes securing not only primary energy isolating mechanisms but also secondary controls, such as a push button that could accidentally energize equipment. A wide range of lockout tagout devices is available to accommodate different equipment types and control configurations, ensuring that facilities can tailor their energy control strategies to match specific operational needs. Compliance depends on knowing the OSHA Lockout Tagout Standard, which defines the rules for hazardous energy control.

Lockout Devices vs Tagout Devices

While both are used to prevent the unexpected startup or release of stored energy, they serve different functions and offer varying levels of protection:

• Lockout Devices are physical restraints—typically padlocks or mechanical attachments—that hold an energy isolating device in a safe or "off" position. They provide a positive means of securing energy isolation.

• Lockout Tagout Devices are warning labels or signs attached to energy-isolating devices. While they don’t provide physical restraint, they communicate that the equipment must not be operated. OSHA allows tagout alone only when an energy isolation method is not feasible and when additional safety measures are in place.

Whenever possible, OSHA mandates that lockout is preferred over tagout because it provides a more secure form of energy control. A closer look at OSHA Lockout Tagout Requirements reveals the specific steps employers must follow for compliance.

Types of Lockout Tagout Devices

There is no one-size-fits-all device. Each type is designed for specific energy control points and must be selected based on the nature of the equipment and the energy involved. Every facility needs a documented Lockout Tagout Program to integrate policy, procedures, and training into daily operations.

1. Electrical Plug Locks

Used to cover and secure electrical plugs on portable equipment. These devices prevent the plug from being reinserted into the outlet during servicing.

2. Circuit Breaker Locks

These are applied directly to circuit breakers, preventing them from being switched back to the "on" position. Models vary depending on the type of breaker and the manufacturer.

3. Valve Locks

• Ball Valve Lockouts: Encase the valve handle to prevent rotation.

• Gate Valve Lockouts: Fit over the valve wheel and are usually adjustable by diameter.

• Butterfly Valve Lockouts: Clamp the valve handle in place to prevent movement.

4. Pneumatic Locks

Used on air compressor lines to block airflow. These devices typically clamp directly to the air hose connection or the fitting.

5. Plug and Cord 

Enclose power cords or plugs to block access. This is useful in environments where machinery is powered by a simple power cord.

6. Group Lockout Boxes

These allow multiple workers to apply their personal locks to a central box holding the primary lockout key. It ensures that no single worker can re-energize the equipment until all locks are removed. When several employees are involved, Group Lockout Tagout provides a method to protect everyone working on shared equipment.

7. Lockout Hasps

These metal loops enable multiple padlocks to be applied to a single isolation point, a common feature in team-based maintenance scenarios.

8. Tagout Devices

OSHA-compliant warning tags that identify the authorized worker, date, and purpose of the machine lock. Tags must be durable, securely fastened, and legible.

Choosing the Right Device for the Job

Selecting the correct lockout device depends on the type of hazardous energy present and the energy isolating mechanism used. A proper match ensures effectiveness and compliance.

• For electrical panels, circuit breaker safety locks are essential.

• For compressed air systems, pneumatic safety locks or plug safety locks are appropriate.

• Choosing between ball, gate, or butterfly valve safety locks for valves depends on the type of valve and its handle configuration.

When unsure, refer to the equipment manufacturer’s documentation or conduct a hazard assessment. OSHA mandates that lockout tagout devices must be standardized, durable, and substantial enough to prevent accidental removal. Step-by-step guidance is covered in our Lockout Tagout Procedure, outlining how to properly shut down, isolate, and secure equipment.

Examples of Correct and Incorrect Applications

• Correct: Use a gate valve safety lock that completely covers the handwheel and apply a padlock through its designated latch point.
• Incorrect: Placing a tag on a valve without any physical restraint when a lockout tagout device could have been applied.

Improper device use can lead to OSHA violations and, more importantly, create unsafe conditions for workers. Therefore, it’s essential to train authorized employees on proper device selection and use.

LOTO devices are more than safety accessories—they’re essential tools for preventing unintended energy releases. Selecting and applying the right device for each energy isolating point is central to LOTO effectiveness. By understanding the types of hazardous energy and choosing compliant, task-specific equipment, employers can meet OSHA standards while protecting workers from harm.

Selecting the right arc flash protection starts with understanding and following electrical PPE guidelines based on a thorough incident energy assessment of the work environment. This assessment helps determine the potential thermal energy a worker may be exposed to during an arc flash event. Based on this, employers must align task-based protection levels with the appropriate PPE hazard classification, ensuring that each job matches the correct safety equipment level. Organizations can minimize risk by identifying the required protective gear by task while meeting compliance requirements and safeguarding workers from preventable injuries. Use this arc flash PPE requirements chart to match clothing and gear with incident energy levels.

Understanding Hazards and PPE Levels

An arc flash is a dangerous electrical event that can release a violent burst of heat and pressure, causing severe injuries, burns, or even fatalities. To protect against this, NFPA 70E outlines four PPE levels based on incident energy, measured in cal/cm². Each level requires AR clothing and accessories designed to withstand a certain degree of thermal exposure.

PPE categories are based on the incident energy levels likely to be encountered during a task:

• Category 1 (4 cal/cm²): Requires AR shirt and pants or coverall, face shield with wrap-around protection, hard hat, and voltage-rated gloves.

• Category 2 (8 cal/cm²): This category adds an AR balaclava or flash hood and may require a heavier fabric weight.

• Category 3 (25 cal/cm²): Requires a full suit, AR hood, gloves, and hearing protection.

• Category 4 (40 cal/cm²): This category involves multi-layered suits designed for the highest exposure levels. For severe hazard scenarios, read about high-calorie suits on our 100 Cal Arc Flash Suit page.

Understanding the standards for minimum ratings ensures that protection is properly aligned with the electrical hazard classification for the task at hand. To better understand the different protection levels, explore our Arc Flash PPE Category page, which breaks down hazard levels and required gear. The NFPA 70E PPE requirements help define the proper protective equipment for various electrical tasks.

How Arc Flash PPE Requirements Are Determined

There are two acceptable methods under NFPA compliance for determining what PPE is required:

1. Incident Energy Analysis: A detailed engineering assessment calculates thermal energy at working distance. This method provides exact values for incident energy exposure levels and drives specific PPE requirements.

2. PPE Category Tables: Table 130.7(C)(15) and related charts define the PPE required for various tasks and equipment types, providing a simplified way to assess risk when a full engineering analysis is not performed.

Both approaches are valid and should be used according to the system's complexity and the precision needed for task-specific PPE.Selecting the right arc flash clothing is essential for compliance with NFPA 70E and CSA Z462 standards. 

Key Electrical Safety Requirements

In addition to wearing the correct PPE, electrical workers must follow these requirements to ensure safety and legal compliance:

• PPE must be AR and tested to meet or exceed the task's energy exposure.

• Garments must be inspected and maintained regularly for damage, contamination, or wear that could reduce protection.

• PPE must provide full body coverage, leaving no skin exposed during the task.

• PPE should be clearly labeled with ratings in cal/cm².

• Training must be provided to workers on the correct use and limitations of their PPE.

Employers are also responsible for maintaining a documented PPE selection process to ensure workers are properly outfitted based on the risk and job type. Explore the full range of arc flash safety gear required to minimize injuries from electrical incidents.

Best Practices for PPE Implementation

To meet and exceed requirements, companies should:

• Integrate PPE selection into job safety planning.

• Use risk-based PPE assessment tools when possible.

• Maintain and audit PPE inventories to ensure availability and compliance.

• Train staff regularly on PPE care, storage, and donning procedures.

In high-risk environments, incident energy suits and thermal-resistant garments offer additional protection, especially for workers operating close to energized components. Learn what goes into a fully compliant suit by checking out our in-depth page on the Arc Flash Suit, including face shields, gloves, and head protection. Learn how PPE performance is evaluated and rated for arc flash protection to ensure worker safety in high-risk environments.

Arc flash PPE requirements are not static checklists—they are living standards that evolve with each update of NFPA 70E. Organizations create a safer and more compliant electrical work environment by following proper PPE selection guidelines, understanding electrical hazard levels, and enforcing correct usage policies. Proper application of these rules not only satisfies compliance—it saves lives. Arc Flash Category 1 PPE includes basic protective clothing for tasks with low incident energy exposure.

Organizations planning programs can map competencies using this overview of electrical safety training topics before tailoring courses to their workforce.

Workers employed in the electrical field are expected to be very knowledgeable in how to work safely. In Canada, the Electrical Safety Authority (ESA) is one such body that offers tips and guidelines for novice electricians and ordinary laypersons while also being the monitoring body for licensed contractors and electricians. For construction environments, practical checklists in construction electrical safety address site-specific controls and coordination with other trades.

Key tips for working with basic electricity:

• Know the relevant electrical safety code for their province and municipality
• Try to work in a de-energized environment, ensuring the power is off and double-checking with a tester
• Use only approved products, identifiable by the mark of a recognized certification agency (Underwriters Laboratories, UL)
• Always have your work inspected as required by the electrical safety code

In the United States, it is the Occupational Safety and Health Administration (OSHA), a government agency of the Department of Labor responsible for maintaining a safe work environment. Electrical safety is just one aspect of OSHA’s many requirements for worker safety. Anyone who may come into contact with live electricity or an electrical hazard must be trained in electrical safety. OSHA has set forth regulations on the minimum training a worker must have, whether in a classroom or through on-the-job training. To meet these expectations, organizations can reference consolidated electrical safety requirements that translate regulatory language into actionable controls.

Electrical workers must be trained to work safely around de-energized and energized equipment. They must know lockout/tagout procedures for detaching a piece of equipment from its power source, and securing the power source so that it does not become re-energized. A general rule of thumb for working on energized parts is to allow contact up to less than 50 volts. In production settings, proven practices from industrial electrical safety help teams balance uptime with hazard mitigation.

Another part of training includes properly using and caring for portable electrical equipment such as extension cords. Workers must be trained to inspect the equipment for damage visually and connect the equipment to a power source properly.

Employees working around electricity must be trained in the type and proper use of protective equipment (PPE – Personal Protective Equipment). They must know how to use insulated headgear and eye protection in appropriate settings where there is a danger to the head or eyes. Employees must be able to determine when insulated tools should be used (such as working around or on an exposed electrical circuit). Employees who must be trained in electrical safety but are not qualified personnel (unqualified personnel) must also be trained in other electrical safety practices that will keep them safe. Unqualified persons are deemed those not permitted to work on or near exposed live electricity.

Qualified personnel must be trained in how to locate and identify exposed live electrical circuits and equipment. Training must include determining the voltage of these live parts and accurately knowing the distance that voltage can travel through the air.

Arc flash incidents pose a serious threat to electrical workers, often resulting in severe arc flash injuries such as second- and third-degree burns. 

Within this arc flash boundary, the use of personal protective equipment PPE is not optional—it’s essential.

 See our Arc Flash PPE article for more information.

Implementing effective OSHA electrical safety protocols starts with conducting a formal hazard analysis that considers system voltage, fault current, and clearing time.

How Incident Energy Is Calculated Using IEEE 1584

To determine the amount of incident energy that can be released during an arc flash, electrical professionals rely on the IEEE 1584-2018 standard. This calculation takes into account a range of system and environmental variables.

Accurate assessment depends on understanding the following core inputs:

• Arcing Current: The actual current that sustains the arc during the fault event.

• System Voltage: The operating voltage of the equipment under evaluation.

• Available Fault Current: The maximum short-circuit current supplied to the arc.

• Clearing Time: How quickly protective devices interrupt the fault.

• Working Distance: The distance between the arc and the worker, typically 18 inches.

These calculations are essential components of a full arc flash risk assessment and are often conducted using specialized software and data from the facility’s arc flash study (short circuit and coordination studies).

Real-World Example: How Incident Energy Affects PPE

Consider a 480V system with a potential fault current of 30,000 amps. Using IEEE 1584, the resulting incident energy may reach 9.6 cal/cm² at 18 inches.

At this level:

• Workers require arc-rated clothing with an ATPV rating greater than or equal to the calculated exposure (≥12 cal/cm²).

• If clearing time is reduced, incident energy may drop below 8 cal/cm², lowering PPE requirements and improving mobility.

For a deeper understanding of how these figures are determined, please refer to our main Arc Flash Study page.

Techniques to Reduce Incident Energy

Modern facilities use design and operational strategies to lower exposure:

• Current-Limiting Fuses: Interrupt arcs within milliseconds.

• Arc-Resistant Equipment: Redirects blast energy away from personnel.

• Maintenance Mode Switches: Shorten trip times during energized work.

• Zone-Selective Interlocking (ZSI): Improves protective coordination.

NEC requirements (such as Sections 240.67 and 240.87) mandate the reduction of incident energy in certain equipment, reinforcing the importance of proactive design.

These techniques are covered in more depth in our guide to arc flash study requirements, which outlines everything employers must include in a safety study.

Compliance With NFPA 70E and CSA Z462

Both standards require incident energy evaluations as part of a complete electrical safety program. Compliance includes:

• Labeling equipment with incident energy values or PPE categories.

• Providing PPE based on calculated exposure.

• Training workers to recognize and mitigate arc flash hazards.

Skipping these steps exposes companies to citations, liability, and preventable accidents.

For further guidance, see our Arc Flash Study, Arc Flash PPE, OSHA Electrical Safety, and Lockout Tagout (LOTO) resources.

Arc Flash Analysis Training

Companies that skip these steps risk citations, legal liability, and preventable injuries. Discover how to develop a compliant program with our arc flash analysis training courses designed for qualified personnel. A comprehensive electrical safety program should include regular arc flash assessments, incident energy calculations, PPE training, and strict adherence to NFPA 70E compliance standards.

Benefits of Accurate Incident Energy Evaluation

Accurate evaluation delivers:
