Lesson 3 describes lockout and tagout devices and how they are used. Lesson 4 briefly explains the requirements for energy program training and inspections. Page 4 of 4

6 Lesson 2: Energy Control Basics 2001 Introduction & Objectives Welcome to the lesson on energy control basics. FLASH ANIMATION: 2001.SWF/FLA After completing this lesson, you should be able to: List the features of an energy-control procedure Identify sources of hazardous energy Recall the importance of energy-isolating devices and lockout / tagout devices Page 1 of 14

7 2002 Energy-Control Procedures: Definition OSHA requires that employers have energy-control procedures. IMAGE: 2002.SWF/FLA These procedures are used to remove hazardous energy from equipment or machinery before the equipment or machinery is: Serviced Maintenanced Different energy-control procedures are required for different types of equipment, depending on: The type of energy the equipment uses How much energy the equipment uses Similar types of equipment may have similar procedures. Page 2 of 14

8 2003 Energy-Control Procedures: Overview An energy-control procedure must have specific instructions for: Getting the equipment ready for shutdown Shutting down the equipment Disconnecting or isolating the equipment from its energy source Using devices to 1) lock energy away from the equipment ( lockout ) or 2) provide a tag to warn against reconnecting the equipment to its energy source ( tagout ) Getting rid of any stored or leftover energy in the equipment Checking that energy does not re-accumulate in the equipment, if there is a possibility that this could occur Verifying that energy has been removed from the equipment, and that the equipment has been removed from its energy source IMAGE: 2003.SWF/FLA These features of an energy-control procedure will be explained further, as we continue on in the lesson. Page 3 of 14

9 2004 Maintenance and Service Activities Let s first take a closer look at when energy-control procedures must be used. IMAGE: 2004.SWF/FLA Remember: Energy-control procedures must be used when equipment is maintenanced or serviced. Maintenance and service activities include: Construction Installation Setup Adjustment Inspection Modification Maintenance or service work All of these activities require the use of an energy-control procedure. Page 4 of 14

10 2005 Maintenance and Service Activities: Exceptions Energy-control procedures may NOT be required during certain minor servicing activities. Examples of such activities are: Lubrication Cleaning Un-jamming Minor adjustments Minor tool changes IMAGE: 2005.SWF/FLA Energy-control is not required during these activities if: The activity is routine, repetitive, and a basic part of the work of the equipment. The activity occurs during normal production operation (link to glossary) of the equipment. The employer provides another way to protect against worker injury during the activity. Page 5 of 14

11 2006 Hazardous Energy Now let s take a look at what is considered to be hazardous energy. Energy-control procedures are required for the following types of energy: Electrical energy Kinetic energy Thermal energy Click on each type of energy for more information. CLICK TO REVEAL Electrical energy This type of energy comes from sources such as generators, batteries, and capacitors. Energy-control procedures are required for any equipment powered by electrical energy, except if both of the following are true: Exposure to hazardous electrical energy can be completely controlled by unplugging the equipment from an electric outlet. Service workers have sole control of the equipment plug during service activities. Kinetic energy Kinetic energy may also be called mechanical energy. This type of energy is in the moving parts of a mechanical system. For example, a machine that uses motion or rotation has kinetic energy. Hazardous kinetic energy also may be released from potential energy stored in: Pressure vessels Gas cylinders and tanks Hydraulic or pneumatic systems Springs Thermal energy Thermal energy is energy in the form of heat. Thermal energy is produced from: Mechanical work Radiation Chemical reactions Electrical resistance Page 6 of 14

12 2007 Energy Isolation Remember: The first two steps in an energy-control procedure are: Getting the equipment ready for shutdown Shutting down the equipment. IMAGE: 2007.SWF/FLA However, it is not enough just to shut the equipment down. The equipment could re-energize if: There is a short-circuit. Someone accidentally turns the equipment back on. This could injure or kill the worker doing the maintenance. Therefore, the third step in energy control is to disconnect or isolate the equipment from its energy source. Page 7 of 14

13 2008 Energy Isolation Energy is considered to be isolated or blocked when it cannot flow or be used. IMAGE: 2008.SWF/FLA In general, equipment is isolated from its energy source by using a mechanical device that physically blocks the flow or release of energy. Examples of this sort of device are: Manual circuit breakers Disconnect switches Line valves Safety blocks Page 8 of 14

14 2009 Lockout / Tagout Devices The next step in an energy-control procedure is to use a lockout or tagout device. IMAGE: 2009.JPG Remember: An energy-isolating device blocks the flow or release of energy to equipment. A lockout device locks the energy-isolating device in an off/safe position. The device cannot be operated until the lockout device is removed. A tagout device is a notice that warns that the energy-isolating device should NOT be turned to the on/unsafe position. Tagout devices are used for energy-isolating devices that cannot be locked. Lockout and tagout devices and their use will be described in greater detail in the next lesson. Page 9 of 14

15 2010 Releasing Stored Energy The next step in an energy-control procedure is to get rid of any stored or leftover energy in the equipment. IMAGE: 2010.JPG Getting rid of stored energy may include: Discharging capacitors by grounding Releasing or blocking springs that are under tension Venting fluids from pressure vessels or tanks until the internal pressure is equal to atmospheric pressure Allowing all equipment to come to a full stop after it has been shut down and isolated from its energy source Page 10 of 14

16 2011 Energy-Control Procedures: Last Two Steps The last two steps in an energy-control procedure are: Checking to see whether hazardous energy builds back up in the equipment, if there is a possibility that this could occur Verifying that energy has been removed from the equipment, and that the equipment has been removed from its energy source IMAGE: 2011.SWF/FLA These final steps ensure that the equipment is safe to work on.

19 2014 Summary You have completed the lesson on energy control basics. NO IMAGE Remember: OSHA requires employers to have energy-control procedures. These procedures must achieve the following: 1) Prepare equipment for shutdown. 2) Shut down equipment. 3) Isolate equipment from its energy source. 4) Lockout or tagout energy-isolation devices. 5) Release or remove any stored or leftover energy. 6) Check for re-accumulation of hazardous energy. 7) Verify that equipment has been deenergized and isolated from its energy source. Devices used to isolate equipment from energy sources include manual circuit breakers, disconnect switches, line valves, and safety blocks. Energy-isolation devices must be turned to the safe/off position during service work. They also must be locked or tagged out, to make sure they will not accidentally be turned to the on position.

20 Lesson 3: Lockout and Tagout Devices 3001 Introduction & Objections Welcome to the lesson on lockout and tagout devices. FLASH ANIMATION: 3001.SWF/FLA After completing this lesson, you should be able to: Define lockout and tagout Recall when lockout is required and when tagout may be used instead List the required features of lockout and tagout devices Page 1 of 15

21 3002 Lockout Remember: Lockout uses a physical mechanism to hold a line valve, safety block, or other energy-isolating device in the safe/off position. IMAGE: 3002.JPG Lockout is required if all of the following are true: An employee is performing service or maintenance activities on a piece of equipment. Unexpected startup of the equipment could expose the employee to hazardous energy and risk of injury or death. The equipment can be locked out. Page 2 of 15

22 3003 Equipment That Can Be Locked Out A piece of equipment can be locked out if any of the following is true: The equipment is designed with a hasp or other part that makes it possible to attach a lockable energy-isolating device, for example, a lockable electronic disconnect switch. The equipment has a built-in locking mechanism. The equipment has a valve cover, circuit breaker blockout, or other energy-isolating device that can reasonably be locked. IMAGE: 3003.JPG Page 3 of 15

23 3004 Equipment That Cannot Be Locked Out If a piece of equipment cannot be locked out, tagout may be used instead. This is discussed in more detail later in the lesson. IMAGE: 1001.JPG When equipment that cannot be locked out is repaired, renovated, or replaced, a lockable energy-isolating device must be installed. The equipment then must be locked out during service work. Note: Even when equipment can be locked out, tagging out may be okay under certain circumstances. This is described later in the lesson. Page 4 of 15

24 3005 Lockout Devices Lockout devices must be: Provided by the employer Durable enough for workplace conditions Standard in color, shape, or size IMAGE: 3002.JPG Page 5 of 15

25 3006 Lockout Devices Lockout devices also must be: The only devices used for lockout Used only for lockout Very difficult to remove accidentally Labeled with identification Click on each item above for more information. CLICK TO REVEAL The only devices used for lockout This means that the lockout devices provided by the employer are to be used for lockout whenever lockout is required. Other devices may not be used instead. Used only for lockout This means that lockout devices may not be used for any purpose other than lockout. Very difficult to remove accidentally This means that lockout devices must be strong enough to resist accidental removal. For example, it should take extreme force with tools such as bolt cutters to remove the device without its key. Labeled with identification Each lockout device must be labeled with the identification of the specific employee authorized to apply and remove that device. The authorized employee is usually the worker performing the service activity. Each worker should have his or her own lockout device and the single key to that device. Each worker should apply his or her own lockout device whenever working on equipment that requires lockout. Page 6 of 15

26 3007 Tagout Remember: Tagout uses a written warning against re-energizing a piece of equipment. IMAGE: 3007.JPG As compared to lockout devices, tags: Are easier to remove Provide less protection Therefore, tagout may be used instead of lockout only if either of the following is true: The equipment cannot be locked out. The equipment can be locked out, but the specific tagout procedure provides the employee with at least as much protection as would a lockout procedure. Page 7 of 15

27 3008 Tagout For lockable equipment that uses tagout, tagout must provide at least as much protection as would a lockout. IMAGE: 3007.JPG Therefore, the tagout procedure must have all of the required features of an energy-control procedure. In addition, the procedure must have at least one extra safeguard against re-energizing of the equipment during a service activity. Examples of additional safeguards are: Removing an isolating circuit element Removing a valve handle Blocking a controlling switch Opening an extra disconnecting device Page 8 of 15

28 3009 Tagout Devices Tagout devices must: Be provided by the employer Have a standard color, shape, or size Have a standard print and format Be legible and understandable Be attachable by hand NO IMAGE Page 9 of 15

29 3010 Tagout In addition, tagout devices must: Be the only devices used for tagout Be used only for tagout Be durable Warn and give clear instructions Be very difficult to remove accidentally Be labeled with identification Click on each item to learn more. CLICK TO REVEAL Be the only devices for tagout This means that the tagout devices provided by the employer must be used for tagout whenever tagout is required. No other device may be used instead. Be used only for tagout This means that tagout devices may not be used for any other purpose. Be durable Tags must not deteriorate or become illegible even when used in wet environments or near corrosive chemicals. Warn and give clear instructions This means that tagout devices must warn employees of the danger of reenergizing tagged out equipment. They must give clear instructions, such as: Do Not Start! Do Not Open! Do Not Close! Do Not Energize! Do Not Operate! Be very difficult to remove accidentally The tag attachment must be a one-piece nylon cable tie or equivalent. It must: Remain intact in all environments and conditions. Be non-reusable. Be self-locking and non-releasable. Have a minimum unlocking strength of 50 pounds. Be labeled with identification Each tagout device must be labeled with the identification of the specific employee authorized to apply and remove that device This is usually the worker performing the service activity. Page 10 of 15

30 3011 Limitations of Tagout Devices Lockout is preferable to tagout whenever possible. IMAGE: 3011.JPG Tagout devices may create a false sense of security. Remember: Tags are warning devices only. They do not provide the physical protection of a lock. Page 11 of 15

31 3012 Removal of Lockout and Tagout Devices Lockout / tagout devices should be removed ONLY by the person who put them in place. IMAGE: 3012.JPG All other employees must respect locks and tags. If a person who put a lock or tag in place is unable to remove it, the lock or tag should be removed as directed by the employer. When a lockout / tagout device has been removed, all appropriate employees should be informed that: The locks / tags have been removed. The equipment may be reenergized. Page 12 of 15

32 3013 Review Which of the following is a feature of an appropriate lockout device? Note that a particular employee, Joe, is authorized to apply and remove the device. a.
