Electrical Lockout tagout is a safety procedure used when work needs to be done on electrical wiring or equipment. Of course the circuit breaker needs to be shut off first. But what if someone turns the breaker on while work on the wiring is still in progress? The purpose of a lockout tagout device is to prevent that from happening. All lockout tagouts have some things in common. The lockout is installed and a lock is placed on it. Only the electrician doing the work should have the key. A tagout is then placed onto the lock to notify everyone that work on circuit wiring is being done. The tag warns them not to tamper with the device. The tag should have the date and contact information of the electrician performing the work.
You can find more information on our web, so please take a look.
Every electrician must use some lockout tagout device when working on live circuit wiring. OSHA mandates the use of lockout tagout. Electrical Lockout tagout can save lives
– The Panel Lockout is much sturdier and secure than those small, red, circuit breaker lockouts, which can fall off or easily be removed.
-Many different size circuit breaker lockouts are needed to fit different types and sizes of circuit breakers. The Panel Lockout can be used any type or size breaker. It can be installed on any panel cover with screws. In addition, with our clips, the Panel Lockout can be installed on most panel covers without screws.
-The panel door can not be closed when circuit breaker lockouts are installed. Unauthorized personnel will have access to all the unprotected breakers in the panel. The door is always closed and locked with the Panel Lockout.
-Several circuit breakers are easily be locked out with the Panel Lockout with only one padlock.
-When installing a circuit breaker lockout there is a danger of accidentally tripping an adjacent breaker. The Panel Lockout is installed outside the panel so there is no chance of accidentally disturbing an active circuit breaker.
Aside from its use as a lockout tagout device, the Panel Lockout is also a time saving tool in new construction. During construction, we often wait until the last minute to terminate wiring onto live panels in order to keep the wires to the field dead as long as possible. Panel trims and covers aren’t installed until the wires are terminated. With the Panel Lockout, as soon as all the wires are installed they can be terminated. Then the panel trims and covers can be installed and all the circuit breakers can be locked out with the Panel Lockout. It eliminates searching for misplaced panel covers at the end of the job and scrambling to terminate panels at the end of the project. In addition, the early completion of the panel wiring prevents wire damage or theft.
The Panel Lockout can be used to keep breakers locked on. Critical equipment must not be accidentally shut down. So, the electrical panel can be locked and therefore unauthorized personnel are kept out.
The Panel Lockout is only 13 inches long, when retracted, and weighs only a few ounces. It fits in a toolbag and can be used on most electrical panels. With the two available extensions, the Panel Lockout can be used on panels from 14 inches to 37 inches wide. The cost of a Panel Lockout is only a fraction other lockout/tagout systems.
We also fabricate a Stainless Steel Panel Lockout. It can be used as a lockout tagout device. Additionally, the Steel Panel Lockout can help stop vandalism and theft in electrical panels and pull boxes. They are 16 inches long when retracted and fit panels or pull boxes from 17 inches to 27 inches wide.
The Steel Panel Lockout is designed to keep vandals from entering an electrical panel or a junction box. With the high price of copper, wire theft has been increasing on construction projects. Theft not only results in a loss of the value of the wire, but also the cost of re-installing it. By using our Steel Panel Lockout to lock panels and junction boxes before the power is turned on, thieves will have a difficult time trying to steal the wire.
The Steel Panel Lockout is also useful for temporary light and power panels on construction jobs. These are panels that should be accessed only by the electrician.
The Steel Panel Lockouts should not be used near exposed live bus or live wires.
Our “Clips for Panels without Screws” will work on most panels. You can see them in out web store. Clips for panels without screws
Click on the photos for close-ups.
The clips will not work on panel covers that wrap around the back box. For those types of panels you can install two screws as follows, or call us for another solution we may have for you
Drill two holes with a # 7 drill bit in the panel backbox edges (at arrows, see photo below). Tap the holes with a 1/4-20 tap. Then drill two corresponding 5/16 inch holes in the panel cover. Install two 1/4-20 panel screws (truss head) through the panel cover into the panel backbox. Then, the Panel Lockout can be used with the standard instructions. When the Panel Lockout is not in use, the two panel screws can remain installed and do not detract from the appearance of the panel.
An easy method to perform the above screw installation
1. Remove the panel cover and make sure there are no wires where you will be drilling. Replace the panel cover.
2. Drill through both the panel cover and the panel backbox at panel edge (at arrows, see photo) with a # 7 drill bit. Remove the panel cover.
3. Enlarge the two holes in the panel cover with a 5/16 drill bit. Tap the two holes in the panel backbox with a 1/4-20 tap.
4. Replace the panel cover and screw in the two panel screws.

CFR 29
[230.70(A)(1)]. In a multiple-occupancy building, each occupant must have access to the service disconnecting means [230.72(C)]. However, if electrical maintenance is provided by continuous building management, the service disconnecting means can be accessible only to building management personnel.
Comment——–The electrician (hired through the building management) is an agent of the building management and is authorized to control access. It is common for a tenant that needs access to a panel to call the building for access. In this case, the electrician’s contact information is on the tagout so access can be gained. The electrician would supervise any access so the circuit breakers he is working on do not get turned on.
The following is a letter ruling from OSHA regarding locking an electrical panel
October 24,
Mr. Jimmy Hill
Safety and Mission Assurance Directorate
Industrial Safety Department
Marshall Space Flight Center
Huntsville, AL
Dear Mr. Hill:
Thank you for your inquiry dated May 24, , regarding clarification of the definition for “Readily accessible” as contained in the Occupational Safety and Health Administration’s (OSHA) electrical standards. This letter constitutes OSHA’s interpretation only of the requirements discussed and may not be applicable to any question not delineated within your original correspondence. We apologize for the delay in our response. Your paraphrased scenario, question, and our response are provided below.
Scenario
It is not a standard practice at the Marshall Space Flight Center to lock electrical panels operating at 600 volts or less, but a request has been received from our Facilities Department to place locks that require a key to open all electrical panels. Locking the panels is to control access by unauthorized employees. A majority of these panels are lighting panels operating at 277 volts and are located throughout the center in office buildings, shop areas, and testing facilities. The breakers in these electrical panels are not used by employees as switches to turn equipment on and off daily.
Question: Does locking the electrical panels operating at 600 volts or less (to control access by unauthorized employees) violate OSHA electrical requirements for not being “Readily accessible” in the event of an emergency?
Response: In accordance with 29 CFR .399, Readily accessible is defined as “capable of being reached quickly for operation, renewal, or inspections, without requiring those to whom ready access is requisite to climb over or remove obstacles or to resort to portable ladders, chairs, etc.” This definition, however, does not preclude the use of a lock on the disconnecting means (circuit breakers panel), provided those, for whom ready access may be necessary, have a key (or lock combination) available. Additionally, the National Electrical Code (NEC) , Article 110.26, partly states, “Enclosures housing electrical apparatus that are controlled by a lock(s) shall be considered accessible to qualified persons.” Please note that the use of multiple locks, which requires different keys or combinations, on disconnecting switches may preclude the installation from being accessible or readily accessible to a particular individual who is authorized to access the panel.
Follow up
Thank you for your interest in occupational safety and health. We hope you find this information helpful. OSHA requirements are set by statute, standards, and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA’s website at www.osha.gov. If you have any further questions, please feel free to contact the Office of General Industry Enforcement at 202-693-.
Sincerely,
Richard E. Fairfax, Director
Directorate of Enforcement Programs
There's no question that electrical safety is a complicated topic. With so many different types of activities and hazards, it can be very catastrophic if not managed appropriately. That’s why it’s so important to have a clear understanding of all the nuances to ensure the safety of your employees. Understanding the overlap and differences between electrical safety and lockout tagout safety is a prime example.
Why the distinction between lockout tagout safety and electrical safety has wide-reaching effects
Oftentimes, the terms “lock out” and “electrical safety” get confused – and that can impact everything from policies and procedures to knowing who is responsible for doing the work.
Lockout
Lockout refers to the mechanical isolation of hazardous energy on a piece of equipment ensuring it gets to a zero energy state. Any equipment with two or more hazardous energies present requires specific, written lockout procedures based on the OSHA standard .147 and Canada's CSA-Z460.
Electrical Safety
When you’re dealing with electrical safety, such as work on an electrical panel, you are not required to have a lockout procedure due to electricity being a single source of hazardous energy. However, you will need to have an electrical safety protocol guiding your overall electrical activities with any specific electrical task. These guidelines are governed by the NFPA 70E as well as OSHA 29 CFR Subpart S and CSA-Z462 requirements (if your business operates in Canada).
Understanding roles and responsibilities
There can also be confusion over who is qualified to conduct service and maintenance activities within an electrical device or panel. At times, organizations have a very small group of designated maintenance employees responsible for everything within a facility – from servicing a piece of equipment from a mechanical standpoint to conducting electrical work within a panel. If that person is not specifically trained to do electrical work, there’s a significant increase in the potential for incidents or fatalities as a result of things like arc flash or electrical shock. The importance of having the right person for the job or task is crucial.
Authorized Individual
For lockout, we are generally talking about “authorized individuals.” These are employees who have been given approval by the organization and trained based on .147 to shut down a piece of equipment according to that specific equipment’s lockout procedure. Not only should authorized individuals be trained on their role and responsibility to .147, but specific practical training for the unique policies and procedures that are particular to an organization's environment, equipment, and process for each piece of equipment they will encounter.
Supporting your safety program
Proper training is what helps keep your employees safe so it’s important to understand when specialized training is required. Whether it’s for lockout or electrical safety, you need to be aware of what equipment is being worked on, what type of task is being done, who is doing it, and what type of hazards are present. Once you assess these essential pieces of information, then you can accurately determine the type of training necessary. Training should be customized to each organization and specific to the type of equipment based on the tasks and responsibilities being asked of your employees.
If you are a company with limited internal resources, it’s important to note that there are third-party options available to help you safely perform many of these tasks. Master Lock has the experience to help you keep your people safe and your business compliant – from evaluating your program and writing policies and procedures to helping you maintain your program moving forward.
