iv Control of Hazardous Energy (Lockout/Tagout) 
Background 

How should I use this booklet? 

This booklet presents OSHA’s general requirements for 

controlling hazardous energy during service or maintenance 

of machines or equipment. It is not intended to replace or to 

supplement OSHA standards regarding the control of hazardous 

energy. After reading this booklet, employers and other 

interested parties are urged to review the OSHA standards 

on the control of hazardous energy to gain a complete 

understanding of the requirements regarding the control of 

hazardous energy. These standards, as well as other relevant 

resources, are identified throughout this publication. 

What is lockout/tagout? 

“Lockout/tagout” refers to specific practices and procedures 

to safeguard employees from the unexpected energization or 

startup of machinery and equipment, or the release of hazardous 

energy during service or maintenance activities.1 This requires, 

in part, that a designated individual turns off and disconnects 

the machinery or equipment from its energy source(s) before 

performing service or maintenance and that the authorized 

employee(s) either lock or tag the energy-isolating device(s) to 

prevent the release of hazardous energy and take steps to verify 

that the energy has been isolated effectively. If the potential 

exists for the release of hazardous stored energy or for the 

reaccumulation of stored energy to a hazardous level, the 

employer must ensure that the employee(s) take steps to prevent 

injury that may result from the release of the stored energy.

 Lockout devices hold energy-isolation devices in a safe or 

“off” position. They provide protection by preventing machines 

or equipment from becoming energized because they are 

1 The standard refers to servicing and maintaining “machines or 

equipment.” Although the terms “machine” and “equipment” have 

distinct meanings, this booklet uses the term “machines” to refer both 

to machines and equipment. This is done for purposes of brevity only, 

and readers should not infer that it is intended to limit the scope of the 

standard. The term “equipment” is broad in scope and encompasses all 

types of equipment, including process equipment such as piping systems. 

How should I use this booklet? 1 
positive restraints that no one can remove without a key or other 

unlocking mechanism, or through extraordinary means, such as 

bolt cutters. Tagout devices, by contrast, are prominent warning 

devices that an authorized employee fastens to energy-isolating 

devices to warn employees not to reenergize the machine while 

he or she services or maintains it. Tagout devices are easier to 

remove and, by themselves, provide employees with less 

protection than do lockout devices. 

Why do I need to be concerned about lockout/tagout? 

Employees can be seriously or fatally injured if machinery 

they service or maintain unexpectedly energizes, starts up, or 

releases stored energy. OSHA’s standard on the Control of 

Hazardous Energy (Lockout/Tagout), found in Title 29 of the 

Code of Federal Regulations (CFR) Part 1910.147, spells out 

the steps employers must take to prevent accidents associated 

with hazardous energy. The standard addresses practices and 

procedures necessary to disable machinery and prevent the 

release of potentially hazardous energy while maintenance or 

servicing activities are performed. 

Two other OSHA standards also contain energy control 

provisions: 29 CFR 1910.269 and 1910.333. In addition, 

some standards relating to specific types of machinery contain 

deenergization requirements—such as 29 CFR 1910.179(l)(2)(i)(c) 

(requiring the switches to be “open and locked in the open position” 

before performing preventive maintenance on overhead and gantry 

cranes).2 The provisions of Part 1910.147 apply in conjunction 

with these machine-specific standards to assure that employees will 

be adequately protected against hazardous energy. 

2 The standard provides a limited exception to the requirement that energy 

control procedures be documented. If an employer can demonstrate the 

existence of EACH of the eight elements listed in 1910.147(c)(4)(i), 

the employer is not required to document the energy control procedure. 

However, the exception terminates if circumstances change and ANY 

of the elements no longer exist. 

2 Control of Hazardous Energy (Lockout/Tagout) 
OSHA Coverage 

How do I know if the OSHA standard applies to me? 

If your employees service or maintain machines where 

the unexpected startup, energization, or the release of stored 

energy could cause injury, the standard likely applies to you. 

The standard applies to all sources of energy, including, but 

not limited to: mechanical, electrical, hydraulic, pneumatic, 

chemical, and thermal energy. 

The standard does not cover electrical hazards from work 

on, near, or with conductors or equipment in electric utilization 

(premise wiring) installations, which are outlined by Subpart S 

of 29 CFR Part 1910. You can find the specific lockout and 

tagout provisions for electrical shock and burn hazards in 

29 CFR Part 1910.333. Controlling hazardous energy in 

installations for the exclusive purpose of power generation, 

transmission, and distribution, including related equipment for 

communication or metering, is covered by 29 CFR 1910.269. 

The standard also does not cover the agriculture, construction, 

and maritime industries or oil and gas well drilling and servicing. 

Other standards concerning the control of hazardous energy, 

however, apply in many of these industries/situations. 

When does the standard not apply to service and maintenance

activities performed in industries covered by Part 1910? 

The standard does not apply to general industry service 

and maintenance activities in the following situations, when: 

 Exposure to hazardous energy is controlled completely 

by unplugging the equipment from an electric outlet and 

where the employee doing the service or maintenance has 

exclusive control of the plug. This applies only if electricity 

is the only form of hazardous energy to which employees 

may be exposed. This exception encompasses many 

portable hand tools and some cord and plug connected 

machinery and equipment. 

How do I know if the OSHA standard applies to me? 3 
 An employee performs hot-tap operations on pressurized 

pipelines that distribute gas, steam, water, or petroleum 

products, for which the employer shows the following: 

– Continuity of service is essential; 

– Shutdown of the system is impractical; and 

– The employee follows documented procedures and 

uses special equipment that provides proven, effective 

employee protection. 

 The employee is performing minor tool changes or other 

minor servicing activities that are routine, repetitive, and 

integral to production, and that occur during normal 

production operations. In these cases, employees must 

have effective, alternative protection. 

How does the standard apply to general industry service

and maintenance operations? 

The standard applies to the control of hazardous energy when 

employees are involved in service or maintenance activities 

such as constructing, installing, setting up, adjusting, inspecting, 

modifying, and maintaining or servicing machines or equipment. 

These activities include lubricating, cleaning or unjamming 

machines, and making adjustments or tool changes, where 

the employees may be exposed to hazardous energy. 

If a service or maintenance activity is part of the normal 

production operation, the employee performing the servicing 

may be subjected to hazards not normally associated with 

the production operation itself. Although machine guarding 

provisions in Subpart O of 29 CFR 1910 cover most normal 

production operations, workers doing service or maintenance 

activities during normal production operations must follow 

lockout/tagout procedures if they: 

 Remove or bypass machine guards or other safety devices, 

 Place any part of their bodies in or near a machine’s point 

of operation, or 

4 Control of Hazardous Energy (Lockout/Tagout) 
 Place any part of their bodies in a danger zone associated 

with machine operations. 

Work involving minor tool changes and adjustments or 

other minor servicing activities that are routine, repetitive, and 

integral to the use of the production equipment and that occur 

during normal production operations are not covered by the 

lockout/tagout standard. This exception is limited, however, and 

applies only when economic considerations prevent the use of 

prescribed energy-isolation measures and when the employer 

provides and requires alternative measures to ensure effective, 

alternative protection.

 Whenever the standard is applicable, the machinery must 

be shut off and isolated from its energy sources, and lockout or 

tagout devices must be applied to the energy-isolation devices. 

In addition, the authorized employee(s) must take steps to verify 

that he or she has effectively isolated the energy. When there 

is stored or residual energy, the authorized employee(s) must 

take steps to render that energy safe. If the possibility exists 

for reaccumulation of stored energy to hazardous levels, the 

employer must ensure that the worker(s) perform verification 

steps regularly to detect such reaccumulation before it has the 

potential to cause injury. 

How does the standard apply to general industry operations? 5 
Requirements of the Standard 

What are OSHAs requirements? 

OSHA’s standard establishes minimum performance 

requirements for controlling hazardous energy. The standard 

specifies that employers must establish an energy-control 

program to ensure that employees isolate machines from 

their energy sources and render them inoperative before 

any employee services or maintains them. 

As part of an energy-control program, employers must: 

 Establish energy-control procedures for removing the 

energy supply from machines and for putting appropriate 

lockout or tagout devices on the energy-isolating devices 

to prevent unexpected reenergization. When appropriate, 

the procedure also must address stored or potentially 

reaccumulated energy; 

 Train employees on the energy-control program, including 

the safe application, use, and removal of energy controls; 

and 

 Inspect these procedures periodically (at least annually) 

to ensure that they are being followed and that they remain 

effective in preventing employee exposure to hazardous 

energy. 

If employers use tagout devices on machinery that can be 

locked out, they must adopt additional measures to provide the 

same level of employee protection that lockout devices would 

provide. Within the broad boundaries of the standard, employers 

have the flexibility to develop programs and procedures that 

meet the needs of their individual workplaces and the particular 

types of machines being maintained or serviced. 

6 Control of Hazardous Energy (Lockout/Tagout) 
What must an energy-control procedure include? 

Employers must develop, document, and use procedures 

to control potentially hazardous energy.3 The procedures 

explain what employees must know and do to control hazardous 

energy effectively when they service or maintain machinery. 

If this information is the same for the various machines used at 

a workplace, then a single energy-control procedure may suffice. 

For example, similar machines (those using the same type and 

magnitude of energy) that have the same or similar types of 

control measures can be covered by a single procedure. 

Employers must develop separate energy-control procedures 

if their workplaces have more variable conditions such as 

multiple energy sources, different power connections, or 

different control sequences that workers must follow to shut 

down various pieces of machinery. 

The energy-control procedures must outline the scope, 

purpose, authorization, rules, and techniques that employees 

will use to control hazardous energy sources, as well as 

the means that will be used to enforce compliance. These 

procedures must provide employees at least the following 

information: 

 A statement on how to use the procedures; 

 Specific procedural steps to shut down, isolate, block, 

and secure machines; 

 Specific steps designating the safe placement, removal, 

and transfer of lockout/tagout devices and identifying 

who has responsibility for the lockout/tagout devices; and 

 Specific requirements for testing machines to determine 

and verify the effectiveness of lockout devices, tagout 

devices, and other energy-control measures. 

3 The standard provides a limited exception to the requirement that energy 

control procedures be documented. If an employer can demonstrate the 

existence of EACH of the eight elements listed in 1910.147(c)(4)(i), 

the employer is not required to document the energy control procedure. 

However, the exception terminates if circumstances change and ANY 

of the elements no longer exist. 

What must an energy-control procedure include? 7 
In Appendix A to 1910.147, OSHA provides a Typical 

Minimal Lockout Procedure for employers to consult when 

preparing their own specific energy-control procedures. The 

outline is a nonmandatory guideline to help employers and 

employees comply with the standard. Nothing in the appendix 

adds to or detracts from any of the requirements in the standard. 

What must workers do before they begin service

or maintenance activities? 

Before beginning service or maintenance, the following 

steps must be accomplished in sequence and according to the 

specific provisions of the employer’s energy-control procedure: 

(1) Prepare for shutdown; 

(2) Shut down the machine; 

(3) Disconnect or isolate the machine from the energy 

source(s); 

(4) Apply the lockout or tagout device(s) to the 

energy-isolating device(s); 

(5) Release, restrain, or otherwise render safe all potential 

hazardous stored or residual energy. If a possibility 

exists for reaccumulation of hazardous energy, regularly 

verify during the service and maintenance that such 

energy has not reaccumulated to hazardous levels; and 

(6) Verify the isolation and deenergization of the machine. 

What must workers do before they remove their

lockout or tagout device and reenergize the machine? 

Employees who work on deenergized machinery may 

be seriously injured or killed if someone removes lockout/tagout 

devices and reenergizes machinery without their knowledge. 

Thus, it is extremely important that all employees respect lockout 

and tagout devices and that only the person(s) who applied these 

devices remove them. 

8 Control of Hazardous Energy (Lockout/Tagout) 
Before removing lockout or tagout devices, the employees 

must take the following steps in accordance with the specific 

provisions of the employer’s energy-control procedure: 

 Inspect machines or their components to assure that they 

are operationally intact and that nonessential items are 

removed from the area; and 

 Check to assure that everyone is positioned safely and 

away from machines. 

After removing the lockout or tagout devices but before 

reenergizing the machine, the employer must assure that all 

employees who operate or work with the machine, as well as 

those in the area where service or maintenance is performed, 

know that the devices have been removed and that the machine 

is capable of being reenergized. (See Sections 6(e) and (f) of 

29 CFR Part 1910.147 for specific requirements.) In the rare 

situation in which the employee who placed the lockout/tagout 

device is unable to remove that device, another person may 

remove it under the direction of the employer, provided that the 

employer strictly adheres to the specific procedures outlined in 

the standard. (See 29 CFR 1910.147(e)(3).) 

When do I use lockout and how do I do it? 

You must use a lockout program (or tagout program that 

provides a level of protection equal to that achieved through 

lockout) whenever your employees engage in service or 

maintenance operations on machines that are capable of being 

locked out and that expose them to hazardous energy from 

unexpected energization, startup, or release of stored energy. 

The primary way to prevent the release of hazardous 

energy during service and maintenance activities is by using 

energy-isolating devices such as manually operated circuit 

breakers, disconnect switches, and line valves and safety 

blocks. Lockout requires use of a lock or other lockout device 

to hold the energy-isolating device in a safe position to prevent 

machinery from becoming reenergized. Lockout also requires 

What must workers do before they remove their lockout or tagout device? 9 
employees to follow an established procedure to ensure that 

machinery will not be reenergized until the same employee 

who placed the lockout device on the energy-isolating device 

removes it. 

How can I determine if the energy-isolating device

can be locked out? 

An energy-isolating device is considered “capable of being 

locked out” if it meets one of the following requirements: 

 Is designed with a hasp or other part to which you can 

attach a lock such as a lockable electric disconnect switch; 

 Has a locking mechanism built into it; or 

 Can be locked without dismantling, rebuilding, or replacing 

the energy-isolating device or permanently altering its 

energy-control capability, such as a lockable valve cover 

or circuit breaker blockout. 

What do I do if I cannot lock out the equipment? 

Sometimes it is not possible to lock out the energy-isolating 

device associated with the machinery. In that case, you must 

securely fasten a tagout device as close as safely possible to the 

energy-isolating device in a position where it will be immediately 

obvious to anyone attempting to operate the device. You also 

must meet all of the tagout provisions of the standard. The tag 

alerts employees to the hazard of reenergization and states that 

employees may not operate the machinery to which it is attached 

until the tag is removed in accordance with an established 

procedure. 

10 Control of Hazardous Energy (Lockout/Tagout) 
What other options do I have? 

If it is possible to lock out an energy-isolating device, 

employers must use lockout devices unless they develop, 

document, and use a tagout procedure that provides 

employees with a level of protection equal to that provided 

by a lockout device. In a tagout program, an employer can 

attain an equal level of protection by complying with all 

tagout-related provisions of the standard and using at least one 

added safety measure that prevents unexpected reenergization. 

Such measures might include removing an isolating circuit 

element, blocking a controlling switch, opening an extra 

disconnecting device, or removing a valve handle to minimize 

the possibility that machines might inadvertently be reenergized 

while employees perform service and maintenance activities. 

When can tagout devices be used instead of lockout devices? 

When an energy-isolating device cannot be locked out, the 

employer must modify or replace the energy-isolating device 

to make it capable of being locked out or use a tagout system. 

Whenever employers significantly repair, renovate, or modify 

machinery or install new or replacement machinery, however, 

they must ensure that the energy-isolating devices for the 

machinery are capable of being locked out. 

Tagout devices may be used on energy-isolating devices 

that are capable of being locked out if the employer develops 

and implements the tagout in a way that provides employees 

with a level of protection equal to that achieved through a 

lockout system. 

When using a tagout system, the employer must comply 

with all tagout-related provisions of the standard and train 

employees in the limitations of tags, in addition to providing 

normal hazardous energy control training for all employees. 

What other options do I have? 11 
What are the limitations of tagout devices? 

A tagout device is a prominent warning that clearly states 

that the machinery being controlled must not be operated until 

the tag is removed in accordance with an established procedure. 

Tags are essentially warning devices and do not provide the 

physical restraint of a lock. Tags may evoke a false sense of 

security. For these reasons, OSHA considers lockout devices 

to be more secure and more effective than tagout devices in 

protecting employees from hazardous energy. 

What are the requirements for lockout/tagout devices? 

Whether lockout or tagout devices are used, they must 

be the only devices the employer uses in conjunction with 

energy-isolating devices to control hazardous energy. 

The employer must provide these devices and they must 

be singularly identified and not used for other purposes. 

In addition, they must have the following characteristics: 

 Durable enough to withstand workplace conditions. 

Tagout devices must not deteriorate or become illegible 

even when used with corrosive components such as acid 

or alkali chemicals or in wet environments. 

 Standardized according to color, shape, or size. Tagout 

devices also must be standardized according to print and 

format. Tags must be legible and understandable by all 

employees. They must warn employees about the hazards 

if the machine is energized, and offer employees clear 

instruction such as: “Do Not Start,” “Do Not Open,” 

“Do Not Close,” “Do Not Energize,” or “Do Not Operate.” 

 Substantial enough to minimize the likelihood of 

premature or accidental removal. Employees should be 

able to remove locks only by using excessive force with 

special tools such as bolt cutters or other metal-cutting 

tools. Tag attachments must be non-reusable, self-locking, 

and non-releasable, with a minimum unlocking strength 

12 Control of Hazardous Energy (Lockout/Tagout) 
of 50 pounds. Tags must be attachable by hand, and 

the device for attaching the tag should be a one-piece 

nylon cable tie or its equivalent so it can withstand all 

environments and conditions. 

 Labeled to identify the specific employees authorized to 

apply and remove them. 

What do employees need to know about lockout/tagout programs? 

Training must ensure that employees understand the 

purpose, function, and restrictions of the energy-control 

program. Employers must provide training specific to the 

needs of “authorized,” “affected,” and “other” employees. 

“Authorized” employees are those responsible for 

implementing the energy-control procedures or performing 

the service or maintenance activities. They need the 

knowledge and skills necessary for the safe application, 

use, and removal of energy-isolating devices. They also 

need training in the following: 

 Hazardous energy source recognition; 

 The type and magnitude of the hazardous energy 

sources in the workplace; and 

 Energy-control procedures, including the methods and 

means to isolate and control those energy sources. 

“Affected” employees (usually machine operators or users) 

are employees who operate the relevant machinery or whose 

jobs require them to be in the area where service or maintenance 

is performed. These employees do not service or maintain 

machinery or perform lockout/tagout activities. Affected 

employees must receive training in the purpose and use of 

energy-control procedures. They also need to be able to do 

the following: 

 Recognize when the energy-control procedure is being 

used, 

What are the requirements for lockout/tagout devices? 13 
 Understand the purpose of the procedure, and 

 Understand the importance of not tampering with lockout 

or tagout devices and not starting or using equipment 

that has been locked or tagged out. 

All other employees whose work operations are or may 

be in an area where energy-control procedures are used must 

receive instruction regarding the energy-control procedure 

and the prohibition against removing a lockout or tagout 

device and attempting to restart, reenergize, or operate 

the machinery. 

In addition, if tagout devices are used, all employees 

must receive training regarding the limitations of tags. 

(See 29 CFR 1910.147(c)(7)(ii).) 

When is training necessary? 

The employer must provide initial training before starting 

service and maintenance activities and must provide retraining 

as necessary. In addition, the employer must certify that 

the training has been given to all employees covered by the 

standard. The certification must contain each employee’s name 

and dates of training. 

Employers must provide retraining for all authorized and 

affected employees whenever there is a change in the following: 

 Job assignments, 

 Machinery or processes that present a new hazard, or 

 Energy-control procedures. 

Retraining also is necessary whenever a periodic inspection 

reveals, or an employer has reason to believe, that shortcomings 

exist in an employee’s knowledge or use of the energy-control 

procedure. 

14 Control of Hazardous Energy (Lockout/Tagout) 
What if I need power to test or position machines, equipment,

or components? 

OSHA allows the temporary removal of lockout or tagout 

devices and the reenergization of the machine only in limited 

situations for particular tasks that require energization—for 

example, when power is needed to test or position machines, 

equipment, or components. However, this temporary exception 

applies only for the limited time required to perform the 

particular task requiring energization. Employers must provide 

effective protection from hazardous energy when employees 

perform these operations. The following steps must be 

performed in sequence before reenergization: 

1. Clear tools and materials from machines. 

2. Clear employees from the area around the machines. 

3. Remove the lockout or tagout devices as specified in 

the standard. 

4. Energize the machine and proceed with testing or 

positioning. 

5. Deenergize all systems, isolate the machine from the 

energy source, and reapply energy-control measures 

if additional service or maintenance is required. 

The employer must develop, document, and use energy-control 

procedures that establish a sequence of actions to follow whenever 

reenergization is required as a part of a service or maintenance 

activity, since employees may be exposed to significant risks 

during these transition periods. 

What if I need power to test or position machines? 15 
What if I use outside contractors for service 

or maintenance procedures? 

If an outside contractor services or maintains machinery, 

the onsite employer and the contractor must inform each other 

of their respective lockout or tagout procedures. The onsite 

employer also must ensure that employees understand and 

comply with all requirements of the contractor’s energy-control 

program(s). 

What if a group performs service or maintenance activities? 

When a crew, department, or other group performs service 

or maintenance, they must use a procedure that provides all 

employees a level of protection equal to that provided by 

a personal lockout or tagout device. Each employee in the 

group must have control over the sources of hazardous energy 

while he or she is involved in service and maintenance activities 

covered by the standard. Personal control is achieved when each 

authorized employee affixes a personal lockout/tagout device to 

a group lockout mechanism instead of relying on a supervisor 

or other person to provide protection against hazardous energy. 

Detailed requirements of individual responsibilities are provided 

in 29 CFR 1910.147(f)(3)(ii)(A) through (D). Appendix C of 

OSHA Directive STD 1-7.3, 29 CFR 1910.147, the Control of 

Hazardous Energy (Lockout/Tagout)-Inspection Procedures 

and Interpretive Guidance, (September 11, 1990), provides 

additional guidance. 

What if a shift changes during machine service or maintenance? 

Employers must make sure that there is a continuity of 

lockout or tagout protection. This includes the orderly transfer 

of lockout or tagout device protection between outgoing and 

incoming shifts to control hazardous energy. When lockout 

or tagout devices remain on energy-isolation devices from 

a previous shift, the incoming shift members must verify 

for themselves that the machinery is effectively isolated 

and deenergized.

How often do I need to review my lockout/tagout procedures? 

Employees are required to review their procedures at least 

once a year to ensure that they provide adequate worker 

protection. As part of the review, employers must correct any 

deviations and inadequacies identified in the energy-control 

procedure or its application. 

What does a review entail? 

The periodic inspection is intended to assure that employees 

are familiar with their responsibilities under the procedure and 

continue to implement energy-control procedures properly. 

The inspector, who must be an authorized person not involved 

in using the particular control procedure being inspected, must 

be able to determine the following: 

 Employees are following steps in the energy-control 

procedure; 

 Employees involved know their responsibilities under 

the procedure; and 

 The procedure is adequate to provide the necessary 

protection, and what changes, if any, are needed. 

For a lockout procedure, the periodic inspection must 

include a review of each authorized employee’s responsibilities 

under the energy-control procedure being inspected. Where 

tagout is used, the inspector’s review also extends to affected 

employees because of the increased importance of their role in 

avoiding accidental or inadvertent activation of the machinery. 

In addition, the employer must certify that the designated 

inspectors perform periodic inspections. The certification 

must specify the following: 

 Machine or equipment on which the energy-control 

procedure was used, 

 Date of the inspection, 

 Names of employees included in the inspection, and 

 Name of the person who performed the inspection.

What additional information does OSHA provide

about lockout/tagout? 

To gain a more comprehensive understanding of the 

requirements for controlling hazardous energy, employers 

and other interested persons should review the following: 

 OSHA standards with provisions regarding the control of 

hazardous energy such as 29 CFR 1910.147, The control 

of hazardous energy (lockout/tagout); 29 CFR 1910.269, 

Electric power generation, transmission, and distribution; 

and 29 CFR 1910.333, Selection and use of work practices. 

Employers in the maritime, agriculture, and construction 

industries are urged to review the provisions for the control 

of hazardous energy contained in 29 CFR Parts 1915, 1917, 

1918, 1925, and 1926. 

 The regulatory preambles to 29 CFR 1910.147 

(54 Federal Register 36644 (September 1, 1989)) and 

1910.269 (59 Federal Register 4320 (January 31, 1994)), 

which contain comments from interested parties and 

OSHA’s explanation for the provisions of the standards. 

 OSHA instructions concerning the control of hazardous 

energy—Directive CPL 2-1.18A, Enforcement of the 

Electrical Power Generation, Transmission, and Distribution 

Standard (October 20, 1997) and OSHA Directive 

STD 1-7.3, 29 CFR 1910.147, the Control of Hazardous 

Energy (Lockout/Tagout)-Inspection Procedures and 

Interpretive Guidance, (September 11, 1990). 

 OSHA letters of interpretation regarding the application 

of standards concerning the control of hazardous energy. 

Most of these documents are available on the OSHA 

website at www.osha.gov. 

18 Control of Hazardous Energy (Lockout/Tagout) 
Additionally, OSHA offers a variety of web-based tools to 

help educate employers and employees about the lockout/tagout 

standard and how to apply it in their workplace. These include 

the following: 

 The Lockout/Tagout Interactive Training Program, which 

includes a tutorial, five abstracts with a detailed discussion 

of major lockout/tagout issues involved, and interactive 

case studies; 

 The Lockout/Tagout Plus Expert Advisor, an interactive, 

expert, diagnostic software package to help users 

understand and apply OSHA standards that protect workers 

from the release of hazardous energy; and 

 The Lockout/Tagout electronic Compliance Assistant Tool 

(eCAT), an illustrated tool to help businesses identify and 

correct workplace hazards. 

These tools are available on the OSHA website at 

www.osha.gov. For the Lockout/Tagout Interactive Training 

Program, click on Technical Links. For the Expert Advisor and 

eCAT, click on eTools.

Commonly Used Terms 21 
OSHA Assistance, Programs, and Services 

How can OSHA help me? 

OSHA can provide extensive help through a variety of 

programs, including assistance about safety and health 

programs, state plans, workplace consultations, voluntary 

protection programs, strategic partnerships, training and 

education, and more. 

How does safety and health program management assistance

help employers and employees? 

Effective management of worker safety and health 

protection is a decisive factor in reducing the extent and 

severity of work-related injuries and illnesses and their related 

costs. In fact, an effective safety and health program forms the 

basis of good worker protection and can save time and money 

—about $4 for every dollar spent—and increase productivity. 

To assist employers and employees in developing effective 

safety and health programs, OSHA published recommended 

Safety and Health Program Management Guidelines (Federal 

Register 54(18):3908-3916, January 26, 1989). These voluntary 

guidelines can be applied to all worksites covered by OSHA. 

The guidelines identify four general elements that are 

critical to the development of a successful safety and health 

management program: 

 Management leadership and employee involvement, 

 Worksite analysis, 

 Hazard prevention and control, and 

 Safety and health training. 

The guidelines recommend specific actions under each of 

these general elements to achieve an effective safety and health 

program. The Federal Register notice is available online at 

www.osha.gov. 

22 Control of Hazardous Energy (Lockout/Tagout) 
What are state plans? 

State plans are OSHA-approved job safety and health 

programs operated by individual states or territories instead 

of Federal OSHA. The Occupational Safety and Health Act 

of 1970 (OSH Act) encourages states to develop and operate 

their own job safety and health plans and permits state 

enforcement of OSHA standards if the state has an approved 

plan. Once OSHA approves a state plan, it funds 50 percent 

of the program’s operating costs. State plans must provide 

standards and enforcement programs, as well as voluntary 

compliance activities that are at least as effective as those 

of Federal OSHA. 

There are 26 state plans: 23 cover both private and public 

(state and local governments) employment, and 3 (Connecticut, 

New Jersey, and New York) cover only the public sector. 

For more information on state plans, see the listing at the end 

of this publication, or visit OSHA’s website at www.osha.gov. 

How can consultation assistance help employers? 

In addition to helping employers identify and correct 

specific hazards, OSHA’s consultation service provides free, 

onsite assistance in developing and implementing effective 

workplace safety and health management systems that 

emphasize the prevention of worker injuries and illnesses. 

Comprehensive consultation assistance provided by OSHA 

includes a hazard survey of the worksite and an appraisal of all 

aspects of the employer’s existing safety and health management 

system. In addition, the service offers assistance to employers 

in developing and implementing an effective safety and health 

management system. Employers also may receive training and 

education services, as well as limited assistance away from the 

worksite. 

What are state plans? 23 
Who can get consultation assistance and what does it cost? 

Consultation assistance is available to small employers 

with fewer than 250 employees at a fixed site and no more 

than 500 corporatewide who want help in establishing and 

maintaining a safe and healthful workplace. 

Funded largely by OSHA, the service is provided at no cost 

to the employer. Primarily developed for smaller employers 

with more hazardous operations, the consultation service is 

delivered by state governments employing professional safety 

and health consultants. No penalties are proposed or citations 

issued for hazards identified by the consultant. The employer’s 

only obligation is to correct all identified serious hazards within 

the agreed-upon correction time frame. 

Can OSHA assure privacy to an employer who asks for

consultation assistance? 

OSHA provides consultation assistance to the employer with 

the assurance that his or her name and firm and any information 

about the workplace will not be routinely reported to OSHA 

enforcement staff. 

Can an employer be cited for violations after receiving

consultation assistance? 

If an employer fails to eliminate or control a serious hazard 

within the agreed-upon timeframe, the Consultation Project 

Manager must refer the situation to the OSHA enforcement 

office for appropriate action. This is a rare occurrence, 

however, since employers request the service for the expressed 

purpose of identifying and fixing hazards in their workplaces. 

What incentives does OSHA provide for seeking

consultation assistance? 

Under the consultation program, certain exemplary 

employers may request participation in OSHA’s Safety and 

Health Achievement Recognition Program (SHARP). Eligibility 

24 Control of Hazardous Energy (Lockout/Tagout) 
for participation in SHARP includes, but is not limited to, 

receiving a full-service, comprehensive consultation visit, 

correcting all identified hazards, and developing an effective 

safety and health management system. 

Employers accepted into SHARP may receive an exemption 

from programmed inspections (not complaint or accident 

investigation inspections) for a period of 1 year initially, or 

2 years upon renewal. 

For more information concerning consultation assistance, see 

the list of consultation offices beginning on page 34, contact 

your regional or area OSHA office, or visit OSHA’s website at 

www.osha.gov. 

What are the Voluntary Protection Programs? 

Voluntary Protection Programs (VPPs) represent one part 

of OSHA’s effort to extend worker protection beyond the 

minimum required by OSHA standards. VPP— along with 

onsite consultation services, full-service area offices, and 

OSHA’s Strategic Partnership Program (OSPP)— represents a 

cooperative approach which, when coupled with an effective 

enforcement program, expands worker protection to help meet 

the goals of the OSH Act. 

How does the VPP work? 

There are three levels of VPPs: Star, Merit, and Demonstration. 

All are designed to do the following: 

 Recognize employers who have successfully developed 

and implemented effective and comprehensive safety and 

health management systems; 

 Encourage these employers to continuously improve 

their safety and health management systems; 

 Motivate other employers to achieve excellent safety 

and health results in the same outstanding way; and 

 Establish a relationship between employers, employees, 

and OSHA that is based on cooperation. 

What incentives does OSHA provide for seeking consultation assistance? 25 
How does VPP help employers and employees? 

VPP participation can mean the following: 

 Reduced numbers of worker fatalities, injuries, and 

illnesses; 

 Lost-workday case rates generally 50 percent below 

industry averages; 

 Lower workers’ compensation and other injury- and 

illness-related costs; 

 Improved employee motivation to work safely, 

leading to a better quality of life at work; 

 Positive community recognition and interaction; 

 Further improvement and revitalization of already-good 

safety and health programs; and 

 A positive relationship with OSHA. 

How does OSHA monitor VPP sites? 

OSHA reviews an employer’s VPP application and conducts 

a VPP Onsite Evaluation to verify that the safety and health 

management systems described are operating effectively at 

the site. OSHA conducts onsite evaluations on a regular basis, 

annually for participants at the Demonstration level, every 18 

months for Merit, and every 3 to 5 years for Star. Each February, 

all participants must send a copy of their most recent annual 

evaluation to their OSHA regional office. This evaluation must 

include the worksite’s record of injuries and illnesses for the 

past year. 

Can OSHA inspect an employer who is participating in the VPP? 

Sites participating in VPP are not scheduled for regular, 

programmed inspections. OSHA handles any employee 

complaints, serious accidents, or significant chemical releases 

that may occur at VPP sites according to routine enforcement 

procedures. 

26 Control of Hazardous Energy (Lockout/Tagout) 
Additional information on VPP is available from OSHA 

national, regional, and area offices, listed beginning on page 34. 

Also, see Outreach at OSHA’s website at www.osha.gov. 

How can a partnership with OSHA improve worker safety and health? 

OSHA has learned firsthand that voluntary, cooperative 

partnerships with employers, employees, and unions can be a 

useful alternative to traditional enforcement and an effective 

way to reduce worker deaths, injuries, and illnesses. This is 

especially true when a partnership leads to the development and 

implementation of a comprehensive workplace safety and health 

management system. 

What is OSHAs Strategic Partnership Program (OSPP)? 

OSHA Strategic Partnerships are alliances among labor, 

management, and government to foster improvements in 

workplace safety and health. These partnerships are voluntary, 

cooperative relationships between OSHA, employers, employee 

representatives, and others such as trade unions, trade and 

professional associations, universities, and other government 

agencies. OSPPs are the newest member of OSHA’s family of 

cooperative programs. 

What do OSPPs do? 

These partnerships encourage, assist, and recognize the 

efforts of the partners to eliminate serious workplace hazards 

and achieve a high level of worker safety and health. Whereas 

OSHA’s Consultation Program and VPP entail one-on-one 

relationships between OSHA and individual worksites, most 

strategic partnerships seek to have a broader impact by 

building cooperative relationships with groups of employers 

and employees. 

Can OSHA inspect an employer who is participating in the VPP? 27 
What are the different kinds of OSPPs? 

There are two major types: 

 Comprehensive, which focuses on establishing 

comprehensive safety and health management systems 

at partnering worksites; and 

 Limited, which helps identify and eliminate hazards 

associated with worker deaths, injuries, and illnesses, or 

have goals other than establishing comprehensive worksite 

safety and health programs. 

OSHA is interested in creating new OSPPs at the national, 

regional, and local levels. OSHA also has found limited 

partnerships to be valuable. Limited partnerships might address 

the elimination or control of a specific industry hazard. 

What are the benefits of participation in the OSPP? 

Like VPP, OSPP can mean the following: 

 Fewer worker fatalities, injuries, and illnesses; 

 Lower workers’ compensation and other injury- and 

illness-related costs; 

 Improved employee motivation to work safely, leading to 

a better quality of life at work and enhanced productivity; 

 Positive community recognition and interaction; 

 Development of or improvement in safety and health 

management systems; and 

 Positive interaction with OSHA.

OSHA office or go to the agency website at www.osha.gov. 

28 Control of Hazardous Energy (Lockout/Tagout) 
Does OSHA have occupational safety and health training for

employers and employees? 

Yes. The OSHA Training Institute in Des Plaines, IL, 

provides basic and advanced training and education in safety 

and health for federal and state compliance officers, state 

consultants, other federal agency personnel, and private-sector 

employers, employees, and their representatives. 

Institute courses cover diverse safety and health topics 

including electrical hazards, machine guarding, personal 

protective equipment, ventilation, and ergonomics. The facility 

includes classrooms, laboratories, a library, and an audiovisual 

unit. The laboratories contain various demonstrations and 

equipment, such as power presses, woodworking and welding 

shops, a complete industrial ventilation unit, and a sound 

demonstration laboratory. More than 57 courses dealing with 

subjects such as safety and health in the construction industry 

and methods of compliance with OSHA standards are available 

for personnel in the private sector. 

In addition, OSHA’s 73 area offices are full-service centers 

offering a variety of informational services such as personnel 

for speaking engagements, publications, audiovisual aids on 

workplace hazards, and technical advice. 

Does OSHA give money to organizations for training and education? 

OSHA awards grants through its Susan Harwood Training 

Grant Program to nonprofit organizations to provide safety and 

health training and education to employers and workers in the 

workplace. The grants focus on programs that will educate 

workers and employers in small business (fewer than 250 

employees), train workers and employers about new OSHA 

standards, or a high-risk activities or hazards. Grants are 

awarded for 1 year and may be renewed for an additional 12 months 

depending on whether the grantee has performed satisfactorily. 

Does OSHA have occupational safety and health training? 29 
 

OSHA expects each organization awarded a grant to develop 

a training and/or education program that addresses a safety and 

health topic named by OSHA, recruit workers and employers 

for the training, and conduct the training. Grantees are also 

expected to follow up with people who have been trained to 

find out what changes were made to reduce the hazards in their 

workplaces as a result of the training. 

Each year OSHA has a national competition that is announced 

in the Federal Register and on the Internet at www.osha-slc.gov/ 

Training/sharwood/sharwood.html. If you do not have access 

to the Internet, you can contact the OSHA Office of Training 

and Education, 1555 Times Drive, Des Plaines, IL 60018, 

(847) 297–4810, for more information. 

Does OSHA have other assistance materials available? 

Yes. OSHA has a variety of materials and tools available 

on its website at www.osha.gov. These include eTools, Expert 

Advisors, Electronic Compliance Assistance Tools (eCATS), 

Technical Links, regulations, directives, publications, videos, 

and other information for employers and employees. OSHA’s 

software programs and compliance assistance tools walk you 

through challenging safety and health issues and common 

problems to find the best solutions for your workplace. OSHA’s 

comprehensive publications program includes more than 100 

titles to help you understand OSHA requirements and programs. 

OSHA’s CD-ROM includes standards, interpretations, 

directives, and more and can be purchased on CD-ROM from 

the U.S. Government Printing Office. To order, write to the 

Superintendent of Documents, U.S. Government Printing Office,
