2. Applying only a tag on a control switch de-energizes equipment.
Placing a physical locking mechanism on either the electrical supply cord or the place where the machinery is plugged in is absolutely necessary when using lockout/tagout procedures. Then a tag, hence the name tagout, must be placed on or near the locking device to indicate the source of energy as well as who is working on the machine at the time.
These devices are what serve as both a physical barrier and visual reminder for preventing other people from inadvertently energizing a machine. They can be used for a number of different types of applications regarding energy release. Those include:

12. Arrange the following steps of the lockout procedure in the correct sequence.
(i) SHUT DOWN: Shut it down equipment using the normal stopping procedure (i.e., close valve, open switch, press it down). (ii) ISOLATION: Isolate the machine or equipment from its energy source. (iii) PREPARATION: Communicate to all affected employees that a machine or equipment requires servicing and must be shut down and locked out. (iv) LOCKOUT/TAGOUT: Lock out the energy isolating device(s) with assigned locks and “Danger!” tags. (v) ISOLATION VERIFICATION: Return operating controls to “off” or “neutral” after verifying that the machine is isolated from its energy source. (vi) STORED ENERGY CHECK: Check that the machine is isolated from all energy sources (including residual energy,) first, by making sure that no employee is exposed to it, then by trying normal operating procedure to see if the machine is working.
Lockout/Tagout. A Lockout/Tagout procedure or method should include the following six steps: 1. Preparation 2. Shutdown 3. Isolation 4. Lockout/Tagout 5. Stored energy check 6. Isolation verification.
13 / 26
13. A tagout device must be labeled to identify employees authorized to apply and remove it.
Lockout and tagout devices (locks and tags) must identify the name of the worker applying the device. All energy sources to equipment must be identified and isolated. After the energy is isolated from the machine or equipment, the isolating device (s) must be locked out or tagged out in safe or off position only by the authorized employees.
14 / 26
14. When you cannot lockout the energy isolating device of a machine, you must still attach the tagout device to it, and complete the tagout procedures.
The appropriate lockout/tagout devices are applied to the equipment by each authorized employee working on the equipment or process. The authorized employee(s) must use lockout devices, unless the hazardous energy source cannot be locked out and the supervisor shows that tagout devices alone will provide the same level of protection. In this case, attach the tag at the same location that a lock device would have been attached. Where feasible, supplement each tag with additional safety measures, such as isolating circuit elements, blocking control switches, opening extra disconnect devices, or opening or closing a valve handle.
15 / 26
15. In case the servicing and/or maintenance is performed by a group of employees, who is responsible for executing the tagout/lockout procedure?
In the Lockout/Tagout Procedure, if more than one individual is required to lock out equipment, each shall place his or her own personal lockout device or tagout device on the energy-isolating device (s). When an energy-isolating device cannot accept multiple locks or tags, a hasp or lockbox may be used.
16 / 26
16. Both lockout and tagout devices are required when isolating equipment.
The purpose of both locks and tags is to ensure equipment isn't reenergized before it's safe. Locks and tags are usually applied at breakers or electrical disconnects, traditional plugs, and battery backups because electrical lockout/tagout is the most common. However, any source of power will need a lockout device.
17 / 26
17. Turning off the power switch removes all energy from powered equipment.
Equipment may have stored energy (also residual or potential energy) that resides or remains in the power supply system. When stored energy is released in an uncontrolled manner, individuals may be crushed or struck by objects, moving machinery, equipment or other items. Stored energy can be mechanical, gravitations, hydraulic, or pneumatic. Common examples are: Capacitors, springs, elevated components, rotating flywheels, hydraulic lift systems, air, gas, steam, water pressure, etc.
18 / 26
18. Lockout/Tagout is necessary whenever you are performing service or maintenance around any machine where you could be injured by:
Lockout/Tagout is required when the unexpected energization or start up (or release of stored energy ) of machines, equipment or prime movers could injure workers during cleaning, repairing, servicing, setting-up, adjusting and un-jamming.
19 / 26
19. If a worker is not present to remove his own lock, any co-worker can remove it as long as he first makes sure it its safe?
ONLY the employer of the authorized employee may remove a lockout device as long as a documented procedure is followed. This procedure, at a minimum, must include: (1) verification by the employer that the [authorized] employee [who applied the device] is not on site; (2) [all] reasonable efforts to contact the authorized employee to inform him or her that the lock has been removed; and (3) the employee is definitely informed of the removal of the lock upon his or her return to work.
20 / 26
20. Before removing the lock you must do which of the following?
21 / 26
21. Once you have isolated a system from its main power source, you can be sure no energy will reach the equipment.
