8 Company Name Lockout/Tagout Procedure I. OBJECTIVE The objective of this procedure is to establish a means of positive control to prevent the accidental starting or activating of machinery or systems while they are being repaired, cleaned and/or serviced. This program serves to: A. Establish a safe and positive means of shutting down machinery, equipment and systems. B. Prohibit unauthorized personnel or remote control systems from starting machinery or equipment while it is being serviced. C. Provide a secondary control system (tagout) when it is impossible to positively lockout the machinery or equipment. D. Establish responsibility for implementing and controlling lockout/tagout procedures. E. Ensure that only approved locks, standardized tags and fastening devices provided by the company will be utilized in the lockout/tagout procedures. II. ASSIGNMENT OF RESPONSIBILITY A. Responsible Person will be responsible for implementing the lockout/tagout program. B. Responsible Persons are responsible for enforcing the program and insuring compliance with the procedures in their departments. C. Responsible Person is responsible for monitoring the compliance of this procedure and will conduct the annual inspection and certification of the authorized employees. D. Authorized employees (those listed in Attachment A) are responsible for following established lockout/tagout procedures. E. Affected employees (all other employees in the facility) are responsible for insuring they do not attempt to restart or re-energize machines or equipment which are locked out or tagged out. III. PROCEDURES The ensuing items are to be followed to ensure both compliance with the OSHA Control of Hazardous Energy Standard and the safety of our employees. A. Preparation for Lockout or Tagout Employees who are required to utilize the lockout/tagout procedure (see Attachment A) must be knowledgeable of the different energy sources and the proper sequence of shutting off or disconnecting energy means. The four types of energy sources are: 7

9 1. electrical (most common form); 2. hydraulic or pneumatic; 3. fluids and gases; and 4. mechanical (including gravity). More than one energy source may be utilized on some equipment and the proper procedure must be followed in order to identify energy sources and lockout/tagout accordingly. See Attachment F for specific procedure format. B. Electrical 1. Shut off power at machine and disconnect. 2. Disconnecting means must be locked or tagged. 3. Press start button to see that correct systems are locked out. 4. All controls must be returned to their safest position. 5. Points to remember: a. If a machine or piece of equipment contains capacitors, they must be drained of stored energy. b. Possible disconnecting means include the power cord, power panels (look for primary and secondary voltage), breakers, the operator's station, motor circuit, relays, limit switches, and electrical interlocks. c. Some equipment may have a motor isolating shut-off and a control isolating shut-off. d. If the electrical energy is disconnected by simply unplugging the power cord, the cord must be kept under the control of the authorized employee or the plug end of the cord must be locked out or tagged out. C. Hydraulic/Pneumatic 1. Shut off all energy sources (pumps and compressors). If the pumps and compressors supply energy to more than one piece of equipment, lockout or tagout the valve supplying energy to the piece of equipment being serviced. 2. Stored pressure from hydraulic/pneumatic lines shall be drained/bled when release of stored energy could cause injury to employees. 3. Make sure controls are returned to their safest position (off, stop, standby, inch, jog, etc.). D. Fluids and Gases 1. Identify the type of fluid or gas and the necessary personal protective equipment. 2. Close valves to prevent flow, and lockout/tagout. 3. Determine the isolating device, then close and lockout/tagout. 4. Drain and bleed lines to zero energy state. 5. Some systems may have electrically controlled valves. If so, they must be shut off and locked/tagged out. 6. Check for zero energy state at the equipment. 8

10 E. Mechanical Energy Mechanical energy includes gravity activation, energy stored in springs, etc. 1. Block out or use die ram safety chain. 2. Lockout or tagout safety device. 3. Shut off, lockout or tagout electrical system. 4. Check for zero energy state. 5. Return controls to safest position. F. Release from Lockout/Tagout 1. Inspection: Make certain the work is completed and inventory the tools and equipment that were used. 2. Clean-up: Remove all towels, rags, work-aids, etc. 3. Replace guards: Replace all guards possible. Sometimes a particular guard may have to be left off until the start sequence is over due to possible adjustments. However, all other guards should be put back into place. 4. Check controls: All controls should be in their safest position. 5. The work area shall be checked to ensure that all employees have been safely positioned or removed and notified that the lockout/tagout devices are being removed. 6. Remove locks/tags: Remove only your lock or tag. G. Service or Maintenance Involving More than One Person When servicing and/or maintenance is performed by more than one person, each authorized employee shall place his own lock or tag on the energy isolating source. This shall be done by utilizing a multiple lock scissors clamp if the equipment is capable of being locked out. If the equipment cannot be locked out, then each authorized employee must place his tag on the equipment. H. Removal of an Authorized Employee s Lockout/Tagout by the Company Each location must develop written emergency procedures that comply with (e)(3) to be utilized at that location. Emergency procedures for removing lockout/tagout should include the following: 1. Verification by employer that the authorized employee who applied the device is not in the facility. 2. Make reasonable efforts to advise the employee that his/her device has been removed. (This can be done when he/she returns to the facility). 3. Ensure that the authorized employee has this knowledge before he/she resumes work at the facility. 9

11 I. Shift or Personnel Changes Each facility must develop written procedures based on specific needs and capabilities. Each procedure must specify how the continuity of lockout or tagout protection will be ensured at all times. See (e)(4). J. Procedures for Outside Personnel/Contractors Outside personnel/contractors shall be advised that the company has and enforces the use of lockout/tagout procedures. They will be informed of the use of locks and tags and notified about the prohibition of attempts to restart or re-energize machines or equipment that are locked out or tagged out. The company will obtain information from the outside personnel/contractor about their lockout/tagout procedures and advise affected employees of this information. The outside personnel/contractor will be required to sign a certification form. If outside personnel/contractor has previously signed a certification that is on file, additional signed certification is not necessary. K. Training and Communication Each authorized employee who will be utilizing the lockout/tagout procedure will be trained in the recognition of applicable hazardous energy sources, type and magnitude of energy available in the work place, and the methods and means necessary for energy isolation and control. Each affected employee (all employees other than authorized employees utilizing the lockout/tagout procedure) shall be instructed in the purpose and use of the lockout/tagout procedure, and the prohibition of attempts to restart or re-energize machines or equipment that are locked out or tagged out. Training will be certified using Attachment B (Authorized Personnel) or Attachment C (Affected Personnel). The certifications will be retained in the employee personnel files. L. Periodic Inspection A periodic inspection (at least annually) will be conducted of each authorized employee under the lockout/tagout procedure. This inspection shall be performed by the (Responsible person). If (Responsible person) is also using the energy control procedure being inspected, then the inspection shall be performed by another party. The inspection will include a review between the inspector and each authorized employee of that employee's responsibilities under the energy control (lockout/tagout) procedure. The inspection will also consist of a physical inspection of the authorized employee while performing work under the procedures. The (Responsible person) shall certify in writing that the inspection has been performed. The written certification (Attachment D) shall be retained in the individual's personnel file. 10

19 Lockout/Tagout General Checklist Use the following checklist when locking and tagging out: Identify ALL sources of electrical energy for the circuits, tools and equipment in question. Disable backup energy sources such as generators and batteries. Identify all shut-offs for each energy source. Notify all personnel that equipment and circuitry must be shut off, locked out and tagged out. (Turning a switch off is NOT enough.) Shut off energy sources and lock switchgear in the OFF position. Each worker should apply his or her individual lock (if necessary). DO NOT give your key to anyone. Test equipment and circuitry to make sure they are de-energized. This must be done by a qualified person. Deplete stored (residual) energy by bleeding, blocking, grounding, etc. Apply a tag to alert other workers than an energy source or piece of equipment has been locked out. Make sure everyone is alerted, safe and accounted for before equipment and circuits are unlocked and turned back on. Not that only a qualified person may determine when it is safe to re-energize circuits. 17

20 Questions to Ask when Locking & Tagging Out Ask the following questions when locking and tagging out: Is all machinery or equipment capable of movement required to be de-energized or disengaged and blocked or locked out during cleaning, servicing, adjusting or setting up operations? If the power disconnected for equipment does not also disconnect the electrical control circuit, are the appropriate electrical enclosures identified and is a means provided to ensure that the control circuit can also be disconnected and locked out? Is the locking out of control circuits instead of locking out the main power disconnects prohibited? Are all equipment control valve handles provided with a means for locking out? Does the lockout procedure require that stored energy (mechanical, hydraulic, air, etc.) be released of blocked before equipment is locked out for repairs? Are appropriate (authorized) employees provided with individually keyed personal safety locks? Are employees required to keep personal control of their key(s) while they have safety locks in use? Is it required that only the employee exposed to the hazard can place or remove the safety lock? Is it required that employees check the safety of the lockout by attempting a startup after making sure no one is exposed? Are employees instructed to always push the control circuit stop button prior to reenergizing the main power switch? Is there a means provided to identify any or all employees who are working on locked out equipment by their locks or accompanying tags? Are a sufficient number of accident prevention signs or tags and safety padlocks provided for any reasonable foreseeable repair emergency? When machine operations, configurations or size require an operator to leave the control station and part of the machine could move if accidentally activated, is the part required to be separately locked out or blocked? If the equipment or lines cannot be shut down, locked out and tagged, is a safe job procedure established and rigidly followed? 18

21 Lockout/Tagout Cautions Hazardous energy releases may occur during the installation, maintenance, service or repair of machines, equipment, processes or systems. Turning off a machine (placing the switch to OFF) for maintenance or repair DOES NOT mean that all the energy from the machine has been released. Authorized employees must know WHY lockout/tagout is important & WHY repairs & maintenance on machines & equipment must not be attempted without first going through proper lockout/tagout procedures. Often, an authorized employee & an affected employee may be the same person. Employers must periodically review the effectiveness of the lockout/tagout program & ensure that all employees are following established guidelines & procedures. Servicing & maintenance activities: constructing, installing, setting up, adjusting, inspecting, modifying, lubricating, cleaning, unjamming, & making tool changes. NEVER use lockout/tagout devices for any other purpose other than locking & tagging out energy sources. Remember, ONLY an authorized employee may apply a lockout device & ONLY that employee should have the key or combination to remove it. Remember, ONLY authorized employees may perform lockout/tagout procedures. NEVER loan out your lockout device & NEVER use another workers lockout device. NEVER apply a lockout/tagout device unless you are instructed to do so by a shop or job foreman, or other appropriate supervisor. NEVER remove another workers lockout/tagout device & NEVER allow another worker to remove your lockout/tagout device. Under certain situations it may be appropriate to position employees in specific locations in order to protect against unauthorized reconnection of energy sources. Remember, tagout devices can be used to add further clarification to lockout devices. If outside personnel refuse to comply with your lockout/tagout procedures & OSHA regulations for any reason, it may be best to refrain from doing business with them. If it is not possible for oncoming personnel to apply their lockout/tagout device(s) before the exiting personnel removes their devices, oncoming personnel should apply their device(s) immediately after the exiting personnel removes theirs. 19

22 Procedures for Isolating and Blocking Energy (Examples) Note: Following are some examples of procedures that are used to isolate and block energy sources. These examples are not meant to be all encompassing and you should be appropriately trained on the lockout/tagout procedures used in your shop. Mechanical Motion Energy Type: Mechanical Motion (rotation, translation, linear, oscillation) Method 1: Remove segments Method of isolating or blocking energy: Remove segments of operating mechanical linkages such as dismantling push rids, removing belts and removing flywheels. Method of securing the point of control: Tag the linkage and place them in a locked cabinet away from the machine. OR Attach warning tags where linkages were removed and restrict access to trained/authorized personnel. OR Post a person to protect against unauthorized reinstallation of the linkages. 20

23 Mechanical Motion Energy Type: Mechanical Motion (rotation, translation, linear, oscillation) Method 2: Blocking devices Method of isolating or blocking energy: Use blocking devices such as wood or metal blocks. Method of securing the point of control: Chain and lock in point of control or use metal pins driven or welded in place. OR Attach warning tags on the blocking devices and restrict access into the area to trained/authorized personnel. OR Post a person to protect against unauthorized removal of the blocking devices. 21

24 Mechanical Motion Energy Type: Mechanical Motion (rotation, translation, linear, oscillation) Method 3: Remove power Note: Method of isolating or blocking energy: Remove power or energy from the driving mechanism such as: Disconnect main electrical source. OR Close hydraulic or pneumatic valves and bleed. Method of securing the point of control: Padlock in the OFF position. Disconnect pneumatic and hydraulic lines and tag. OR Attach warning tags at control points and restrict access to trained/authorized personnel. Post a person to protect against unauthorized reconnection of the energy source. Check for alternate sources of power. Check for stored (residual) pneumatic and hydraulic energy. 22

25 Electrical Energy Energy Type: Electrical Method 1: Turn off disconnect switch Note: Method of isolating or blocking energy: Place the main electrical disconnect switch in the OFF position. Method of securing the point of control: Secure by a padlock, a clip and padlock, or a bar and padlock. OR Attach a warning tag and restrict access into the area to trained/authorized personnel. OR Post a person to protect against unauthorized actuation of the switch. Check for alternate sources of power. 23

26 Electrical Energy Energy Type: Electrical Method 2: Remove electrical circuits Method of isolating or blocking energy: Remove segments of electrical circuit, such as printed circuit modules. Method of securing the point of control: Tag the module and place in a locked cabinet away from the control center and tag the control center door. OR Attach a warning tag at the module location and restrict access to trained/authorized personnel. OR Have a person remain at the control center to protect from unauthorized installation or a spare of replacement module. 24

27 Energy Type: Potential (Pressure) Method: Close valves Potential Energy (Pressure) Method of isolating or blocking energy: Close valves and maintain open vent to relieve. Method of securing the point of control: Secure/block valve with locking device. OR Attach warning tags and restrict access to trained/authorized personnel. OR Station a person at the valves to protect against unauthorized actuation. 25

28 Energy Type: Potential (Gravity) Method: Blocking devices Note: Potential Energy (Gravity) Method of isolating or blocking energy: Block in place by using metal or wood blocks under the mechanism or pin the linkage in a position where gravity will not cause the mechanism to inadvertently fall. Method of securing the point of control: Secure, block or pin with a locking device. OR Attach warning tags to blocks, linkages and pins, and restrict access to trained/authorized personnel. OR Station a person at the mechanism to prevent unauthorized removal of blocks and pins, and reinstallation of linkages. Energy can be dissipated by lowering to a point where gravity could no longer cause inadvertent falling. 26

29 Energy Type: Potential (Springs) Method: Blocking Note: Potential Energy (Springs) Method of isolating or blocking energy: Block in a safe position by pinning or clamping the device, eliminating the potential of unrestricted and undesired travel. Method of securing the point of control: Secure pin or clamp in place with a locking device. OR Attach warning tags to the pins and clamps, and restrict release or access to trained/authorized personnel. OR Station a person at the control point to protect against pin or clamp removal, and unauthorized activation of the spring mechanisms. Spring energy can be dissipated by release or dismantling of the mechanism. 27
