Identify equipment and machinery that require written procedures.
Although there is no requirement to develop a written LOTO Program, you do have the obligation to develop, document, and make sure employees use specific written LOTO procedures for authorized employees to control potentially hazardous energy when they perform servicing or maintenance. Well-written energy control procedures accurately instruct authorized employees to do all of the following:
Inform all affected employees of equipment shutdown
Shut down equipment in the proper order
Identify and engage energy-isolating devices or block hazardous energy
Lockout or tagout the energy-isolating devices
Remove, drain, neutralize, or block any potential (stored) energy
Verify the equipment is isolated from hazardous energy and rendered inoperative
Best Practice: It is considered a best practice to have a written program,
or policy, to support the energy control program, in addition to clearly outlining expectations and accountability.
1. All of the following are methods used during lockout/tagout procedures to protect employees, EXCEPT _____.
a. Obtain approval from the safety department to begin LOTO
b. Dissipate or restrain potential energy that can't be isolated
c. Keep employees clear of energy sources during servicing
d. Verify equipment isolation

You must develop and use a written LOTO procedure for servicing or maintenance on a machine or equipment unless ALL of the following eight criteria are satisfied:
The machine or equipment has no potential for stored or residual energy or reaccumulation of stored energy after shut down which could endanger employees.
The machine or equipment has a single energy source which can be readily identified and isolated.
The isolation and locking out of the energy source will completely deenergize and deactivate the machine or equipment.
The machine or equipment is isolated from the energy source and locked out during servicing or maintenance.
A single lockout device will achieve a lock-out condition.
The lockout device is under the exclusive control of the authorized employee performing the servicing or maintenance.
The servicing or maintenance does not create hazards for other employees.
The employer, in utilizing this exception, has had no accidents involving the unexpected activation or reenergization of the machine or equipment during servicing or maintenance.
2. Which of the following is one of the 8 criteria that must be satisfied before an employer is not required to develop and use written lockout/tagout procedures?
a. Multiple lockout are necessary to achieve a lock-out condition
b. A single lockout device will achieve a lock-out condition
c. The employer has only had minor accidents involving unexpected activation of the machine
d. Identified energy sources may not cause serious injuries during maintenance
What is the scope and purpose of the LOTO procedure? Who authorizes the procedure?
If you can't meet the exception criteria listed in the previous section, written LOTO procedures must be developed and used.
The procedures for equipment with one or more sources of energy must outline the scope, purpose, authorization, rules and techniques that the employer will use to control hazardous energy.
Scope. The scope of lockout/tagout procedures may be limited to a single piece of equipment of machinery or a group of similar pieces of equipment or machinery.
Purpose. The purpose of the procedures is to ensure the unexpected energization/startup or shutdown does not occur during servicing or maintenance activities.
Authority. The responsible manager authorizes the procedures and ensures specific rules/techniques are listed within the procedures.
3. The scope of lockout/tagout procedures may be limited to _____.
a. individually identified pieces of equipment only
b. a single piece or a group of similar pieces of equipment or machinery
c. all equipment or machinery within a process
d. any group of equipment or machinery from the same manufacturer
All equipment purchased after 1990, such as these wind turbines, must be capable of being locked out.
All new machines and equipment, or all machines and equipment that undergo major repair, renovations or modification, must be equipped with energy-isolating devices capable of accepting a lockout device.
Whenever replacement or major repair, renovation or modification of a machine or equipment is performed, and whenever new machines or equipment are installed, energy isolating devices for such machine(s) or equipment must be designed to accept a lockout device.
That's about it for a discussion of the basic components of the ECP. Remember, make sure all three components have been developed and deployed. If OSHA comes inspecting, they will not cut you any slack when it comes to the LOTO program because if something goes wrong, a serious injury or fatality is likely to result.
5. Whenever new machines or equipment are installed or replaced, energy isolating devices for such machine(s) or equipment must _____.
a. be designed to accept a lockout device
b. be installed with tagout devices until operational
c. meet strict NFPA standards for lockout/tagout
d. have OSHA/Manufacturer identification plates attached
