DOL action: Final rule: corrections and technical amendments.* summary: This document amends the final rule on the Control of Hazardous Energy (Lockout/Tagout) (29 CFR 1910.147) which was published on September 1.1989 (54 FR 36645). This action is necessary to correct typographical errors, include some information inadvertently omitted, and correct some inconsistencies in the _ reamble and regulatory text. effective DATE: September 20.1990. FOR FURTHER INFORMATION CONTACT: Mr. James F. Foster. Occupational Safety and Health Administration, room N3649, U.S. Department of Labor. Washington. DC 20210, (202) 523-8148. SUPPLEMENTARY INFORMATION: Background The final standard for the control of hazardous energy (Lockout/Tagout), which was promulgated on September 1. 1989 (54 FR 36644). requires employers to develop an energy control program consisting of the sooption and utilization of written procedures for shutting off and disabling machines and equipment whenever maintenance or servicing are performed on those machines and equipment, the instruction in use of the procedure to employees and the periodic inspection of the use of the procedure. This notice amends the preamble and the standard to correct errors or inconsistencies in those components of the final rule. Accordingly, the Final Rule document oublished September 1.1989 at 54 FR '44-36896, Federal Register Document ~ 89-20574. and 29 CFR 1910.147 are corrected as follows: Preamble 1. Page 36644. column 3. the sentence which begins on line 18 is corrected to read. "The present OSHA regulations for locking out or tagging out machines and equipment, where they do exist, are not uniform in their coverage." 2. On page 36647. column 2, the sentence which begins on line 7 is revised to read. "Practices such as reaching around guards during the cleaning of rollers of printing presses or the feed points or screw conveyors while the equipment is operating, violate the safeguarding requirements set forth in S 1910.212. and therefore, such activities are violations of that rule." 3. On page 366S2. column 2. the sentence beginning on line 27 is revised to read. `These activities differ from other activities which are routinely conducted during normal production operations in that they are usually done only on an as-needed basis." 4. On page 36653. column 2. on lines 5G to 58. one of the "a program which incorporates" is deleted. 5. On page 36654, column 1. the sentence which begins on tine 45 is revised to read. "The most vigorously contested issue was over the need to use locks or tags as the primary' means to prevent operation of energy isolating devices, such as electrical disconnects, hydraulic or pneumatic valves." 6. On page 36655. column 1. the sentence on lines 21-27 is revised to read as follows: "In order to provide adequate protection to employees, tr.e Final Rule requires employers to develop and utilize a comprehensive energy control program consisting of: procedures for shutting down and isolating machines and equipment and locking or tagging out the energy Isolating devices: employee training: and periodic inspections of the energy control procedure to maintain its effectiveness." 7. On page 36655. column 1. the parenthetical phrase beginning on line 66 is corrected to read, "except through extraordinary means such as by the use of bolt-cutters". 8. On page 36655, column 2. the citation on line 29 is corrected to read, "(Tr. pg. H194-214. W2-3 to 2-39)." 9. On page 36656. the first sentence on that page should read. "Some equipment would need to be replaced or modified significantly to accept lockable-type energy isolating devices." 10. On page 36656. coiumn l. the second half of the sentence which begins on line 10 is revised to read. "such efforts are most effectively achieved when done during'machine or equipment replacement, major repair, renovation or modification dr when new equipment is installed rather than retrofitting existing equipment within a set time frame established in this standard." 11. On page 36656. column 1. a new sentence is added beginning on line 38 to read as follows. "Second, retrofitting of existing equipment may not be technologically or economically feasible." 12. On page 36656. column 1. the sentences beginning on line 59 through the end of the paragraph are revised to read. "For such equipment. OSHA will allow employers to use the tagout program as prescribed by (c)(2)(i). but only until the equipment is replaced, or has major repair, renovation or modification performed on it. At that time, the new, renovated or modified equipment must be equipped with lockable energy isolating devices, and the energy control procedure must be revised to make use of that capability, except when the employer can demonstrate that the tagout program in >>3e provides full employee protection." 13. On page 36656. column 2. the sentence beginning on line 6 is revised to read as follows: "OSHA is. confident that this standard is a cost-effective approach to providing protection against the restarting of machines or equipment ,!nd the release of hazardous energy." 14. On page 36656, column 2. the sentence beginning on line 13 is revised to read as follows; It requires that the employer develop and utilize an energy control program consisting of written procedures, employee training and periodic inspections for servicing and maintenance of machines and equipment, using lockout or its equivalent on the great majority of energy isolating devices, namely those which are capable of being locked ouL" 15. On page 36656. column 3. lines 4 through 9 are revised to read, "installed within a cabinet, enclosure or cutout box containing several other energy isolating devices or vaives and the only means of preventing access to the L-nergy isolating device or valve is to lock the doors of the cabinet, enclosure cr box.

On page 36650, column 1. the sentence beginning on line 4 is revised to read. The tag, in this case, supplements the blank flange or blind by identifying the employees performing the maintenance, thereby establishing a method of continuous individual accountability for the employees. An effective system of administrative control, such as the use of a single master tag with provision for individuals to sign in and out as they begin or end their work on the machine or equipment, would satisfy this requirement." 21. On page 36659. column 2. the sentence beginning on line 18 is corrected to read as follows: 'The amount of detail in a procedure for shutting down a simple conveyor with a these operations (paragraph fa)(2)(iii) stated, `when it is necessary to perform the activity and if the activity is performed using alternative measures which the employer can demonstrate are equally effective')." 28. On page 36661. column 2. the sentence which begins on line 20 is revised to read as follows: "These hazards may be manifested when the employee must either remove or bypass guards or other safety devices which were not designed or intended to be removed, when the employee is required to place any part of his or her body Into an unguarded point of operation of the machine or equipment, or when an employee must reach into or enter an associated danger cone when a machine is operating." 27. On page 36661, column 3, the sentence beginning on line 30 is revised to read as follows: `Their reasoning essentially was that if alternative methods are used to keep the employee cut of the danger zone or to eliminate the danger zone, there is nothing for the standard to cover, since the employee condition, provided that the means of control of the machine remain* in the exclusive control of the person afforded the protection. This is necessary to ensure that no other person can restart the machine without the knowledge and consent of the person performing the servicing.'' 31. The sentence beginning on line 14. column 2 of page 36662 is the beginning of a new paragraph. The new paragraph is revised to read as follows; `It must be emphasized that the exclusion from lockout or tagout does not mean that the employer can avoid providing protection. As the exclusion itself makes clear, the work must be performed using alternative safeguarding measures which provide effective employee protection. This will generally involve compliance with OSHA's machine guarding standards throughout the production process.'' 32. On page 36662. column 2. the sentence beginning on line 26 is revised to read as follows: "In evaluating servicing performed during normal production operations, the first question piagle source of power, and single feed would not be exposed to a hazard. fTr. to be asked is whether employees must and discharge points, could be much p.

On page 36359. column 2. the title of the major subdivision of the preamble (line 42) is "Summary and Explanation of the Final Standard". "However," so the sentence reads, "However, minor tool adjustments and changes or other minor servicing activities performed during normal production operations, are not covered 33.

The use of protective measures which prevent employee exposure to hazards, such as specially designed servicing tools and remote oilers, could satisfy the requirements of subpart O. Safeguarding for minor servicing during normal production operations also may include, for example, interlocked barrier guards, local disconnects or control switches which are under the exclusive control of the employee performing the minor servicing, provided they enable the employee to perform such minor servicing without being exposed to the unexpected energization or activation of the equipment or the release of stored energy.'' 34. On page 36663. column 2. the sentence beginning on line 5 to revised to read, "First, process shutdowns and start-ups of equipment of this nature pose extreme hazards of explosion and fire due to the type of materials being handled, and the complexities of and potential interactions between materials being conveyed or otherwise available in the workplace." 35. On page 36664. column l. the sentence beginning on line 12 is revised to read. "This standard requires the development of a program centered around the use of a standardized, written procedure, the training of employees in their *,ole in the successful use of the procedure, and periodic inspections to maintain the effectiveness of the program." 36. On page 36664. column 1. the sentence beginning on line 26 is revised to read. "In paragraph (a)(3)(ii), OSHA states that the intention of the standard is not to replace existing specific OSHA lockout and/or tagout provisions, but to supplement and support these provisions with requirements for using a written procedure, for training employees and for periodic inspections of the use of that procedure." 37. On page 36664. column 1. on line 46. the last entry under the heading Overhead and Gantry Cranes is corrected to read. "1910.179(l)(2)(i) (A), (B). (C), (D)." 3B.

On page 36664. column 3. the sentences beginning on line 11 and ending at line 19 are revised to read. "For the most part they address the importance of the proper installation of energy controls for particular types of equipment. The types of controls required by this category of current rules will determine how such equipment may be isolated from the energy source under this Final Rule." 43. On page 36664. column 3. the sentences beginning on line SO are corrected to read. "An example of a provision which specifies the use of locks as a means of controlling the energy is found in 5 19l0.179(l)(2)(i)(C) which states. The main or emergency switch shall be open and locked in the open position.' Provisions of similar content are found in paragraphs: * * *'' 44. On page 36665. column 1. lines 1 through 8 are corrected to read. "An example of a provision which specifies the use of locks or tags is found in 1910.281(i)(4)(iii) which states. 'When cleaning, inspecting, or other work requires that persons enter the beaters, all control devices shall be locked or tagged out in. accordance with paragraph (b)(4) of this section.' Provisions of similar content are found in the following: *'* 45. On page 36865. column 1. the sentence beginning on line 29 is revised to read. "Provisions of similar content are found in: * *'* 46. On page 36665. column 1. the sentence beginning on line 43 is coiTected to read as follows: "This standard supplements the other provisions in much the same way as with the first category in that it requires the establishment of procedures for energy control, the training of employees and periodic inspections of the procedures." 47. On page 36665, column 1. the sentence beginnmg on line 54 is revised to read as follows: "When current standards require the use of locks and/ or tags, those standards are supplemented rather than replaced by the requirements of this standard for the utilization of written procedures, training of employees and periodic inspections." 48. On page 36665. column 3. the sentences beginning on line 2 through line 35 are corrected to read, "If an employee is performing servicing or maintenance, and therefore must use the energy control procedure, that employee is an "authorized employee". By contrast, an "affected employee" is one who does not perform the servicing or maintenance but whose work duties are performed in an area in which servicing or maintenance is performed. The affected employee needs to know only when the energy control procedure is being used, and to understand the importance of not attempting to start up cr to use the equipment which has been locked out or tagged out. The definition of "authorized employee" also states that an affected employee is an authorized employee whenever that person performs servicing or maintenance covered by this standard on a machine or equipment. In this case, that person, as an authorized employee, must have the training and knowledge to perform the servicing or maintenance safely. 49. On page 36665. column 3. the sentence beginning on line 60 is revised to read. "The revised definition assures ) 9-26-90 Published by THE BUREAU OF NATIONAL AFFAIRS. INC- Washington, O.C. 20037 wvry 000011*30 CURRENT REPORT 777 that vvhen a servicing task is performed by an employee, that employee who is directly exposed to the hazards of the servicing operation will have to affix his/her personal lockout or tagout device before beginning the work and to remove it when he/she completes the ivork." 50. On page 36666, column 1, the sentence beginning on line 62 is revised to read. " 'Energy' as used in the standard means mechanical motion (kinetic energy--the energy of motion}; potential energy due to gravity or springs: electrical energy; thermal energy resulting from high or low temperature: and hydraulic or pneumatic energy." 51. On page 36666, column 2, the sentence beginning on line 9 is revised to read. '"L Mechanical motion (kinetic energy--the energy of motion) may be linear translation, rotation or a combination of the two. This type of energy cannot be turned off or oa but may be contained or stopped." 52. On page 36666. column 2. the sentence beginning on line 14 is corrected to read, "2. Potential energy can be due to the position or location of an object above some datum plane or it can be due to the energy stored in springs. Potential energy can be minimized by moving an object to a lower position. The energy of springs can be dissipated or controlled; it cannot be turned off or on." 53. On page 36666, column 2, a fifth numbered item is added between une 35 and line 33 to read as follows: "5. Hydraulic or pneumatic energy is the pressure (either above or below atmospheric] contained in a iiquid (such as oil or water] or in a gas (such as air). Hydraulic or pneumatic energy may be turned off. Hydraulic or pneumatic energy also may be stored: in which case, it must be released or dissipated." 54. On page 36666, column 3. the sentences beginning at line 44 through line 69 are revised to read, "This adjustment, which is done as part of the normal operation of the machine, is covered by the machine guarding requirements- Guarding must be provided to keep the employee's body away from the point of operation and other hazardous areas of the machine. However, if it becomes necessary, as a minor routine, repetitive activity which is integral to the production process, to change the speed of the machine by adjusting belt drives or other components which are normally guarded, and effective alternative safeguarding is provided which will protect employees from exposure to the hazards addressed by this standard, then the iockout/tagout requirements of this Final Rule do not apply, if effective alternative safeguarding is not provided, the minor servicing is covered by this standard. Similarly, if it becomes necessary to adjust the movement of a long-bed nulling machine worktable and die isolating hydraulic cut-off valve is not in the exclusive control of the person making the adjustment, or this requires the employee to negate the effectiveness f the safeguards so that the employee is exposed to the hazard of unexpected energization of the machine (i.e.. there is no alternative protection), this final standard applies. However, if this step is performed without the employee having to remove or bypass any safeguards or otherwise expose his/her body to the potential release of energy or the unexpected activation of the machine, this Final Rule does not apply." 55. On page 36667. column 1. the sentence beginning on line 37 is corrected to read. "Anything that is done to prepare a machine or equipment to perform its normal production operation, such as changing a machine part (e g., changing the blade of a power saw), is not considered utilization of a machine or equipment and is classified as servicing or maintenance rather than normal production operations." 56. On page 36667, column 1. the sentence on lines 56 through 61 is corrected to read. "The definition of servicing or maintenance includes those activities which require an employee to remove or bypass guards or other safety devices which were not intended to be removed during normal production operations (i.e.. resulting in exposure to the hazards addressed by this standard), or to otherwise expose himself/herseif to hazardous machine elements. 57. On page 36667, column 2. the sentence beginning on line 30 is revised to read. "The Final Rule requires that authorized, affected and other employees be trained in and understand those things which are necessary for each employee to know in order to have servicing or maintenance performed safely." 58. On page 36667. column 3. the sentence beginning on line 3 is corrected to read. "Methods of evaluating and maintaining the effectiveness of these procedures are provided in two other paragraphs of the standard: paragraph (c)(6), which addresses periodic inspections for observing employee adherence to the procedures; and paragraph (c)(7), which covers initial and follow-up training as required to develop and maintain the knowledge and skills needed by employees for the safe application and removal of enercy control devices." 59. On page 36667. column 3, the sentence beginning on line 19 is revised to read. "OSHA makes a distinction between the method of controlling the energy (the type of energy control devices utilized) based primarily upon whether or not the energy isolating device is capable of being locked out." 60. On page 36668, column 3, the sentences beginning on line 68 through line 10 of column 1 of page 36669 are corrected to read. "In lockout, the presence of a servicing employee's lockout device on an energy isolating device will prevent another employee from activating or energizing the equipment, even if that other employee does not understand the restrictions of the energy control program. By contrast, tagout is highly dependent on human factors, and requires constant vigilance to ensure that tagout devices are not removed, bypassed or disregarded." 61. On page 36669. column 1. the sentence beginning on line 14 is revised to read. "Such training, which involves a review of the employee's responsibilities under the energy control program and the limitations of tagout has been incorporated into the periodic inspection requirements ic paragraph (c)(6) of the final Rule, and, as such, must he provided on at least an annual basis." 62. On page 36669. column 1. the sentence beginning on line 21 is revised to read. "In addition, the standard requires that the employer's energy control procedure incorporate provisions for enforcing compliance with the restrictions and prohibitions of the program." 63. On page 36669. column 1, the paragraph beginning on line 31 is corrected to read. "Paragraph (c)(2)(i) states that tagout may be used when the energy devices are not `capable of being locked out1 as defined in the standard. This paragraph allows the employer to use tagout in this limited circumstance. If the employer wishes to perform modifications of the equipment to accommodate a lockout device. OSHA encourages such modifications, but as noted above, the standard does not require them until replacement or major modifications or repairs of the equipment is undertaken." 64. On page 36669. column 1. the first two sentences of the paragraph beginning on line 44 are corrected to read, "In paragraph (c)(2)(H). OSHA requires the use of lockout if the energy isolating devices are `capable of being locked out' unless the employer can demonstrate that the utilization of tagout will provide full employee protection'." 85. On page 36669. column 1. the sentence beginning on iine 54 is 9-26-90 Occupational Safety & Health Reoorter 0000 yv* - 778 OCCUPATIONAL SAFETY & HEALTH REPORTER corrected to read. "In brief, `full employee protection' in this context means that when equipment is capable of being locked out. the employer must demonstrate that the tagout program provides a level of safety equivalent to that obtained by using a lockout program." 66. On page 36669. column 1. a sentence is added beginning on line 63 to read as follows: This will provide additional assurance that the energy isolating device will not be accidentally or inadvertently turned on." 67. On page 36669. column 2. the sentence beginning on line 16 is corrected to read. "In order for an employer to demonstrate that a tagout program provides a level of safety equivalent to a lockout program for a piece of equipment which has lockable energy isolating devices, the employer will need to show additional steps which have been taken to enhance the tagout program." 66. On page 36669. column 2. the sentences beginning on line 50 through 56 are corrected to read. "Several parties contended that because of statistical limitations and due to underreporting, the use of accident data to evaluate an energy control program would not give a true picture of the effectiveness of the program. Similarly, discussions with authorized and iffected employees could be used only for determining the thoroughness of the training and their knowledge of the energy control program." 69. On page 36670. column 1, a sentence is added following the sentence which ends at line 59 to read. "The procedure must detail that information which the authorized employees must know to accomplish the lockout or tagout." 70. On page 36670. column 1. line 67. insert, "such as" before the word "those". 71. On page 36670. column 2. the sentence beginning on line 9 is revised to read. "For example, if there is a machine with a single energy source that must be serviced or maintained, and the means to shut down and isolate the machine is uncomplicated and apparent, such as first pushing a stop button, then opening an electrical disconnect which is at the machine, and locking out that energy isolating device, the written procedure could be very simple." 72. On page 36671. column 1, the sentence beginning on line 22 is corrected to read. "The amount of detail in an employer's procedure will depend 1 the complexity of the machine or .ece of equipment, and what the servicing employee must know to shut down and isolate the machine or equipment" 73. On page 36671, column 3. the sentence beginning on line 7 is corrected to read. "The purpose of the standard as stated in paragraph (a)(3) is to require employers to establish and utilize a program for disabling machines and equipment during their maintenance or servicing in order to prevent injury to employees." 74. On page 36671. column 3. the sentence beginning on line 63 is revised to read. "For the energy control procedure to be effective, these devices must have a single meaning to employees: "Do not energize or attempt to start or operate a machine or equipment when such a device is affixed to an energy isolating device which controls the energy to that machine or equipment".*' 75. On page 3667Z column 2. the sentence beginning on line 5 is corrected to read. "This requirement will enable employers and other employees to determine at a glance which authorized employees are performing a given servicing operation." 76. On page 36672. column 3, the sentence beginning on line 48 is corrected to read. "The proposal was intended to require that tags have some type of commonly used message which would serve to prohibit an employee from removing, bypassing or disregarding the tag." 77.

In these situations, when the complexity of the servicing operation necessitates an alternative to such frequent attachment and removal of lockout or tagout devices, the use of the work permit or comparable means, with each employee signing in and out as he or she begins or stops working on the equipment, combined with the servicing employees verifying that the equipment is deenergized prior to beginning work, would be an acceptable approach to compliance with group lockout/tagout and shift change provisions of the standard." 130.

Appendix A to S 1910.147 is revised to read as follows: Appendix A--Typical Minimal Lockout Procedure General The following simple lockout procedure is provided to assist employers in developing their procedures so they meet the requirements of this standard. 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 (see paragraph (c)(3)) 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 Procedure Lockout procedure for (Name of Company for single procedure or identification of equipment if muLuple procedures are used) Purpose 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, 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 or stored energy could cause injury. Compliance With This Program 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 observing a machine or piece of equipment which is locked out to perform servicing or maintenance shall not attempt to start, energize or use that machine or equipment.

The following guidance relative to specific provisions of 29 CFR 1910.147 is provided to assist compliance officers in conducting inspections where the standard aay be applicable: a. The standard as specified in 39 CFR 1910.147(b). applies to any source at seensnicai. hydraulic, pnsumstie. chemical, mental, or other energy. (1) The standard applies to piping syeteas, and raquira*. at 29 CFR mo.H7(d)(S), that all potentially hasardoue stored or residual energy be relieved, disconnected, restrained, and otherwise rendered safe. If there is a possibility of reaccumulation of stored energy to a hazardous laval, continued monitoring snail be performed while a potential hazard exists. (2) The standard also applies to high intensity electromagnetic fields regulated at 29 CFR 1910.97. nonionizing radiation. Such electromagnetic devices shall be deenergized and held off whenever workers ere present within a nigh intensity ambient field.

(See 29 CFR 1910, Subpert L.) t. The standard does not apply to servicing and aamtenanca when eaployeaa are not exposed to tne unexpected reieese of hazardous energy. ;. Safeguarding workers froa the hazards of contacting electrically live parts lexpoeure to electric current) continues to oe regulated at Subpart S. d. Servicing and maintenance functions conducted during normal production operations ere not regulated at 29 CFR 1910.147 XX the safeguarding provisions of subpart o or other applicable portions at 29 CFR 1910 prevent worker exposure t: hazards creatad by tne unexpected energization er start-up of the machine or equipment. However, lockout/tagaue procedures ere required IX the production safeguards are rendered ineffective while an employee is exposed to hazardous portions of the aachines or equipaent. e. Generally, activities such as lubrication, cleaning ar uniaaming. servicing of aachines or equipmant. and making adjustment* or tool changes, where the employee aay be exposed to the UNEXPECTED energization er start-up of the equipaent or release of hazardous energy, are covered by this standard.

Devices which are not exposed to harsh environments need not be capable of withstanding such exposure. f. 29 cm 1910.147(e)(5)(11)(C)(2) requires that tagout devices having rsusabie, non-locking, easily detacnmble means of attachment (suen as string, cord, or adhesive) are not permitted. Employees and Training. a. The standerd recognises these types of sapleyees: (1) 'authorized* and (2)"affected". defined in 1910.147 (b), and (D'other*. defined in 1910.147 ;)(7)(ill (C). Different level* of training are required based upon the respective roles of employees in the control of energy end tn* knowledge which they must possess to accomplish their tasks safely and te ensure the safety of fallow workers as related to the lockout/tagout procedures (1910.147(c)(7)(D). B. Employees who exclusively perform functions related to normal production operations, and who perform servicing and/or maintenance under the protection of normal sacnin* safeguarding, need only be trained as 'affected* (rather than "authorized*) eapleyeea even if tagout procedures are used. (See, 1.1.d. end I.l.e. of this instruction,) c. The employer's training program suet cover, at a minimum, the following three areas: energy control program, elements of energy control procedures relevant to employe* duties, and the pertinent requirements of the standard (1910.147(c)(7) and id) through (f)!, d. The employer must provide: (2) Effective initial training; 12) l'feetlv* retraining as needed: and ()) Certification of training. The certification snail contain each employee'a name end dates :C training (1910.1*7(c)(7)(iv|i. . Retraining of authorized and affected employees is required: ll) whenever there is a change in eeployee yob assignments: (2) whenever a new hazard is introduced due to a change in macnines, equipment or process: (3) whenever there le a change in the energy control procedures: or 14) Whenever e periodic inspection by the employer reveals inadequacies in the company procedures or in tne knowledge of tn* employees. 5. Periodic Inspection bv the Finlav.r a. At least annually, the employer shell ensure that sn authorized employee other then the oneis) utilizing the energy control procedure being inspected, is required to inspect and varify tne effectiveness of the company energy control procedures. These inspections shall at least provide for a demonstration of the procedures and say be implemented throuqn random audits and planned visual observations. These inspections are intended te ensure that tne energy control procedures are being properly implemented and to provide an essential check on tne continued utilization of tna procedures i29 cFR 1910.147 tci (6) (i)). (l) When lockout is used, the eopioyer's inspection snail include a review of the responsibilities of aacn authorized eaployee implementing the procedure with that eaployee. Group meetings between the authorized employee wno is oerferming the inspection and all authorized employ*** who impleaent tn* procedure vcuid constitute compliance with this requirement. 2) -hen tagout is used, the employer shall conduct this review with *acn affected and authorized employee. energy control procedures used less frequently than once a yeer need be inspected only when used. c. rn* periodic inspection must provide for ana ensure effective correction of identified deficiencies (29 ent 1910.147(cI(SIt11(B] ) . c. The employer is required to certify that the prescribed periodic inspections r.ave been performed (29 CFR 1910.147(cm 6)i11j). 6. Equipment Testing or Positioning. Grider 2$ cm 1910.147(f)(1), OSKA allows tn* temporary removal of lockout or tagout devices and the recnergizacion of the machine or equipment ONLY during the limited time necessary fer the testing or positioning of machines, equipment or components.

Group lcckout/tagout procedures snail be tailored to tha specific industrial operation and may be unique in the Banner that employee protection from the release of hazarcous energy is achieved. Irrespective of the situation, tne requirements of this generic standard specify that aacn atployee performing maintenance or servicing activities snail be in control of hazardous energy during his/her period of exposure. a. Group operations normally require that a loexout/tagout program be implamented which tnsures that each authorized employe* is protected from tn* unexpected release ef hazardous energy by his/her personal lockout/tagout aeviceis). No eaployee may affix tne personal lockout/tagout device of another employee. various group lockout/tagout procedures Ciscusseo in Appendix C provide for each authorized employee's use of his/her personal lockout/tagout devico(S). b. One of the most difficult problems addressed by the standard involves the servicing and eaintenance of complex equipment. Such eguiptent is frequently used in tne petrochemical and chemical industries. Acceptable group lockout/tagout procedures for ccspisx equipment are discussed further at Appendix c. .8 Csnnliance witn Croup Lockout/Taaaut. These operations shall, at a minimum, provide for the following: a. Before the machine or equipment is shut down, each authorizad employe* who is to be involved during the eervicing/maintenanee operation snail be made aware by the employer of the type, magnitude, and Hazard* related to the energy to be controlled and of the method or means to control the energy. In tn* event that tha machine or equipment is already shut down, the authorized employee snail be mad* aware of theae elements before beginning his/her work (29 cm 1910.147(d)(1)). verification shall be performed as noted at l.S.f. of this instruction. 9-26-90 Published by THE BUREAU OF NATIONAL AFFAIRS.
