# MIOSHA Fact Sheet # Lockout/Tagout For Construction MIOSHA Michigan Occupational Safety and Health Administration Construction workers can be exposed to serious physical harm or death if hazardous energy is not properly controlled. The general requirements for lockout/tagout applicable to most construction work practices are located in the Construction Standard Part 1, General Rules - Rule 127. The rule outlines measures for controlling hazardous energies including electrical, mechanical, hydraulic, pneumatic, chemical, thermal and other energy sources. Electricians and linemen who work with electricity every day face a great risk. The specific lockout/tagout requirements to protect employees working on electric circuits, equipment, and power transmission and distribution lines are found in the Construction Standard Part 16, Power Transmission and Distribution – Rule 1926.961(a)-(c)(13); and the Construction Standard Part 17, Electrical Installations - Rule 1724. It is imperative that employers develop a lockout/tagout procedure and provide training for their employees to ensure that they know, understand, and follow the procedure to protect them from being exposed to hazardous energy sources while they are working. ## Critical requirements employers must do to protect their employees. - Develop, implement, and enforce an energy control and lockout/tagout procedure and review annually. • Provide effective training as mandated for all employees covered by the standards. - Use lockout devices for equipment that can be locked out. Tagout devices may be used in lieu of lockout devices only if the tagout program provides employee protection equivalent to that provided through a lockout program. - Ensure that new or overhauled equipment is capable of being locked out. • Develop, implement, and enforce an effective tagout program for machines or equipment that are not capable of being locked out. • Use only lockout/tagout devices authorized for the parti…

NEW YORK COMMITTEE FOR OCCUPATIONAL SAFETY AND HEALTH NYCOSH # How Does Lockout/Tagout Prevent Injury? Lockout/Tagout is used to control hazardous energy, preventing equipment from being energized during repairs or maintenance. Lockout is the preferred method - and the only truly protective one. First, turn off the energy isolating device. Then, use a keyed lock to lock out the energy isolating device. The best way is one worker, one lock, one key. This practice is actually stronger than the OSHA standard. Under the one worker, one lock, one key system: - Each worker needs one lock for each energy source. For example, if there are three different energy sources on a machine, each worker would need three locks. - Multiple workers can use a hardened hasp called a scissors to allow multiple locks. • Each worker needs to remove his/her own lock when servicing work is completed. Tagout is sometimes used, but it should only be used when machines or equipment can't be locked out. Sometimes, as with older equipment, equipment can't be locked out. However, after January 2, 1990: - Equipment undergoing major modifications must get lockout, and - New equipment must be equipped for lockout. - Tags don't provide physical protection - they can't stop someone from turning on equipment. - Tags should have specific information about the job. • Tags should have specific warning messages, such as: "Do Not Start." "Do Not Open." "Do Not Operate." "Do Not Energize." Like a lock, a tag must only be removed by the worker who placed it. SOURCES: The control of hazardous energy (lockout/tagout) - 1910.147 OSHA.

# Lockout/Tagout: Controlling Hazardous Energy ## What is hazardous energy? Hazardous energy is any energy source that, if not isolated or controlled, could create a hazard. Common energy sources are electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other sources in machines and equipment that 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. LOCK-OUT OPERATE DO NOT TAG-OUT DANGER SAVES LIVES ## How can you protect workers from hazardous energy? Failure to control hazardous energy accounts for nearly 10 percent of the serious accidents in many industries. Proper lockout/tagout (LOTO) practices and procedures safeguard workers from hazardous energy releases. OSHA's Lockout/Tagout Fact Sheet* found at osha.gov/sites/default/files/publications/OSHAFS3529.pdf describes the practices and procedures necessary to disable machinery or to prevent hazardous energy release. The OSHA Standard The Control of Hazardous Energy (Lockout/Tagout) (29 CFR 1910.147) found at osha.gov/laws-regs/regulations/standardnumber/1910/1910.147 for general industry outlines measures for controlling different types of hazardous energy. The LOTO standard establishes the employer's responsibility to protect workers from hazardous energy. Employers are also required to train each worker to ensure that they know, understand, and are able to follow the applicable provisions of the hazardous energy control procedures: • Proper lockout/tagout (LOTO) practices and procedures safeguard workers from the release of hazardous energy. The OSHA standard for The Control of Hazardous Energy (Lockout/Tagout) (29 CFR 1910.147) found at osha.gov/laws-regs/regulations/standardnumber/1910/1910.147 for general industry, outlines specific action and procedures for addressing and controlling hazardous energy during servicing and maintenance of machines a…

WORKER HEALTH AND SAFETY ⑪FACT SHEET The Control of Hazardous DANG DANGER Energy (Lockout/Tagout) LOCKED OUT OSHA Oregon OSHA OAR 437 • Division 2/J . DO NOT Masier DO NOT REMOVE Department of Consumer and Business Services OPERAT ## General Industry Requirements OSHA's standard for The Control of Hazardous Energy (Lockout and Tagout), requires that hazardous energy be controlled during service and maintenance activities. These activities include the installation, setup, adjustment, inspection, modification, and routine maintenance or servicing of equipment. Hazardous energy sources include electrical, mechanical, hydraulic, pneumatic, chemical, gravity, and thermal. Equipment must be isolated from its energy sources and rendered inoperative to prevent injury or death from unanticipated, uncontrolled hazardous energy. (Control-circuit type devices are not energy-isolation devices.) Cord-and-plug-connected equipment is not covered under the standard if it's unplugged, the plug is under the exclusive control of the operator, and electricity is the only form of hazardous energy. Employers must develop and enforce an energy control program that consists of energy-control procedures, employee training, and periodic inspections. Requirements include: • Use individual lockout devices for equipment that can be locked out; that uses a positive means such as a lock, either key or combination type, to hold an energy-isolating device in a safe position and prevent the energizing of a machine or equipment. - If an energy isolating device is not capable of being locked out, provide tagout devices instead of lockout devices only if the employer can demonstrate that the use of a tagout program provides full employee protection equivalent to a lockout program. Use additional safety measures as part of the demonstration to reduce the likelihood of inadvertent energization. • Provide additional safety measures such as the removing of an electrical circuit. - Provide durable…

# Controlling hazardous energy (cont.) ## Option 3: Lockout/Tagout (LOTO). (cont.) DANGER A hasp allows multiple authorized employees to individually lock out the same energy isolating device. ## Facts about lockout and tagout devices Lockout and tagout devices must meet the following criteria to ensure that they are effective and not removed inadvertently: Durable. Lockout devices must work properly under the environmental conditions in which they are used. Warnings on tagout devices must be legible even in wet, damp, or corrosive conditions. Standardized. Lockout and tagout devices must be designated by color, shape, or size. Tagout devices must have a standardized print and warning format. Substantial. Lockout devices and tagout devices must be strong enough that they cannot be removed inadvertently. Tagout devices must be attached with a single-use, self-locking material such as a nylon cable tie with a minimum unlocking strength of 50 pounds. Identifiable. Any employee who sees a lockout or tagout device must recognize who attached it and understand its purpose. It must not be used for purposes other than the control of hazardous energy. Unique. Each lock must have a unique key; this means that only the employee who uses the lock has the key to that lock. Payment. If you are an employer, you must provide lockout and tagout devices to employees who need to shutdown equipment to service or maintain it. # Your energy control program You need to accomplish three critical activities to ensure employees' safety when they are servicing or working near equipment that could expose them to hazardous energy: A. Develop written procedures for controlling hazardous energy. B. Train employees in the procedures. C. Conduct inspections of the procedures at least annually. ## A. Develop your written energy control procedures You must document energy control procedures for use by authorized employees who lockout or tagout equipment to perform service and mainte…

# Controlling hazardous energy (cont.) ## 5. Verify equipment isolation Verification means purposely confirming that equip- ment is separated from its energy source; therefore, it is "isolated." The authorized employee must verify that: ▸ Equipment has been properly turned off/shut down. ▸ Energy-isolating devices were identified and used to effectively isolate energy. ▸ Lockout or tagout devices have been attached to the energy-isolating devices. ▸ Stored energy has been removed or controlled. Attempting to restart the equipment is one way to confirm isolation; however, testing equipment ensures that capacitors have been properly discharged, hazardous heat has dissipated, and excessive pressures have been relieved. Best practice: Some companies refer to their energy control program as "Lock, Tag, Try" or "Lock, Tag, Test" to emphasize this important verification step. Warning A word about electrical testing: "A qualified person shall use test equipment to test the circuit elements and electrical parts of equipment to which employees will be exposed and shall verify that the circuit elements and equipment parts are deenergized." [1910.333(b)(2)(iv)(B)] P.D. A-164 Electrical Safety ## Lockout (LO), tagout (TO), or lockout/ tagout (LOTO)? How to decide ## Option 1: Lockout (LO). Lockout follows an estab- lished procedure for placing a lockout device, such as a padlock, on an energy-isolat- ing device to create a physical barrier of protection. If an energy-isolating device can accept a lockout device, you must use lockout. DANGER A PELIGRO 2 Locked out (LO) ## Option 2: Tagout (TO). Tagout is a procedure for placing a warning tag or sign - a tagout device - on an energy-isolating device that cannot accept a lockout device. Tagout devices must control hazardous energy at least as effectively as lockout devices. Since tagout Tagged out (TO) during devices do not provide the vehicle maintenance same physical barrier to hazardous energy as lockout devices…

# SAMPLE LOCKOUT/TAGOUT PROCEDURE The following simple lockout procedure is provided to assist employers in developing their procedures so they meet the requirements of OSHA standard 1910.147. When the energy isolating devices are not lockable, tagout may be used, provided the employer complies with the provisions of the standard which require additional training and more rigorous periodic inspections. When tagout is used and the energy isolating devices are lockable, the employer must provide full employee protection that is specified in paragraph (c)(3) of the standard and additional training and more rigorous periodic inspections are required. For more complex systems, more comprehensive procedures may need to be developed, documented and utilized. Lockout/Tagout procedure for (name of company) at (location)_ for (machine/type of machines) This procedure establishes the minimum requirements for the lockout of energy isolating devices whenever maintenance or servicing is done on machines or equipment. It shall be used to ensure that the machine or equipment is stopped and 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. ## Compliance with this procedure All employees are required to comply with the restrictions and limitations imposed upon them during the use of lockout. The authorized employees are required to perform the lockout in accordance with this procedure. All employees, upon seeing a machine or piece of equipment which is locked out to perform servicing or mainte- nance shall not attempt to start, energize, or use that machine or equipment. (Insert type of disciplinary action to be taken for violation of the above.). ## Sequence of lockout (1) Notify all affected employees that servicing or maintenance is required on a machine or equipment and that the m…
