Note to Reviewer
Combining Information Collection Requests
There are two Information Collection Requests (ICRs) covering Electrical Standards; one for
Construction (Office of Management and Budget (OMB) Control No. 1218-0130) and the other
for General Industry (OMB Control No. 1218-0256). To better ensure consistency and account
for total burden hours and costs being imposed by these standards, OSHA is combining these
two ICRs into one ICR that will cover all of the collection of information requirements contained
in these Standards. The ICR will cover both 29 CFR part 1926, subpart K and 29 CFR part
1910, subpart S, and will be titled, “Electrical Standards for Construction (29 CFR part 1926,
Subpart K) and for General Industry (29 CFR part 1910, subpart S)” and will adopt the existing
OMB Control Number 1218-0130. Upon OMB approval of the combined ICRs, the Agency will
request that OMB discontinue OMB Control No. 1218-0256. The table below, Information
Collection Requests covering the Electrical Standards for Construction and General Industry,
contains the OMB control number, the title of the ICR, current burden hours, responses, and
costs.
Table 1 of the following supporting statement provides a summary of the burden hours and cost
associated with the paperwork provisions of the Standards, and Table 2 provides an explanation
of the adjustment for these provisions. OSHA is proposing to increase the existing burden hour
estimate of the information collection requirements specified by the Standards. The construction
standards’ current burden hours are 83,291, and the general industry’s current burden hours are
9,353 totaling 92,644 hours for both. Combining these two ICRs will increase the current burden
hour estimate from 92,644 hours to 151,172 hours, a total increase of 58,528 hours.

OFFICE OF MANAGEMENT AND BUDGET (OMB)
CONTROL NO. 1218-0130 (September 2008)
JUSTIFICATION
1. Explain the circumstances that make the collection of information necessary. Identify any legal or
administrative requirements that necessitate the collection. Attach a copy of the appropriate section of each
statute and regulation mandating or authorizing the collection of information.
The main objective of the Occupational Safety and Health Act of 1970 (i.e., “the Act”) is to
“assure so far as possible every working man and woman in the Nation safe and healthful
working conditions and to preserve our human resources” (29 U.S.C. 651). To achieve this
objective, the Act authorizes “the development and promulgation of occupational safety and
health standards” (29 U.S.C. 651).
Section 6(b)(7) of the Act specifies that “[a]ny standard promulgated under this subsection shall
prescribe the use of labels or other appropriate forms of warning as are necessary to insure that
employees are apprised of all hazards to which they are exposed, relevant symptoms and
appropriate emergency treatment, and proper conditions and precautions of safe use or
exposure.” This provision goes on to state that “[t]he Secretary, in consultation with the
Secretary of Health and Human Services, may by rule promulgated pursuant to section 553 of
title 5, United States Code, make appropriate modifications in the foregoing requirements
relating to the use of labels or other forms of warning . . . as may be warranted by experience,
information, or medical or technological developments acquired subsequent to the promulgation
of the relevant standard” (29 U.S.C. 655).
Under the authority granted by the Act, the Occupational Safety and Health Administration
(“OSHA” or “the Agency”) published the Electrical Standards for Construction (29 CFR part
1926, subpart K) and General Industry (29 CFR part 1910, subpart S); i.e., “the Standards”). The
Standards address safety procedures for installation and maintenance of electric utilization
equipment that prevent death and serious injuries among construction and general industry
employees in the workplace caused by electrical hazards. Item 2 and 12 below describe the
specific information collection requirements of the Standards.1
2. Indicate how, by whom, and for what purpose the information is to be used. Except for a new collection,
indicate the actual use the Agency has made of the information received from the current collection.
1
The purpose of this Supporting Statement is to analyze and describe the burden hours and costs associated
with provisions of these standards that contain paperwork requirements; this Supporting Statement does not provide
information or guidance on how to comply with, or how to enforce, the Standards.
The information collection provisions in these subparts require labels, markings, written
programs, notifications, and tags to alert employees of the presence and types of electrical
hazards in the workplace, thereby, preventing serious injury and death by electrocution.
The following provisions do not contain an information collection requirement because the
employer does not develop, collect, or maintain the information specified by the provisions.
Instead, the manufacturer provides the information on the equipment (i.e., it is usual and
customary for employers to purchase equipment that have these markings). Therefore, OSHA is
not determining the cost or burden hours for these provisions under Item 12 of this Supporting
Statement.

Paragraph 1910.333(b)(2)(iii)(B) requires employers to ensure that each tag used contains a
statement prohibiting unauthorized operation of the disconnecting means and removal of the tag.
8
Paragraph 1910.333(b)(2)(v)(B) requires employers to warn employees exposed to the hazards
associated with reenergizing the circuit or equipment to stay clear of the circuits and equipment.
3. Describe whether, and to what extent, the collection of information involves the use of automated,
electronic, mechanical, or other technological collection techniques or other forms of information technology,
e.g., permitting electronic submission of responses, and the basis for the decision for adopting this means of
collection. Also describe any consideration of using information technology to reduce burden.
Employers may use automated, electronic, mechanical, or other technological information
collection techniques, or other forms of information technology (e.g., electronic submission of
responses) when establishing and maintaining the required records. The Agency wrote the
paperwork requirements of the Standards in performance-oriented language (i.e., in terms of
what data to collect, not how to record the data).
4. Describe efforts to identify duplication. Show specifically why any similar information already available
cannot be used or modified for use for the purpose(s) described in 2 above.
Some local jurisdictions enforce the National Electrical Code (NEC), which has information
collection requirements similar to the requirements specified by the Standards. However, OSHA
has insufficient data from which to estimate the level of duplication.
Every edition of the NEC from the 1984 edition to the present 2008 edition (representing six
code cycles) requires that specific AEGC tests be conducted, recorded, and made available to the
authority having jurisdiction. However, the specific authority having jurisdiction varies from
state to state.
5. If the collection of information impacts small businesses or other small entities (Item 5 of OMB Form 83I), describe the methods used to reduce the burden.
The information collection requirements specified by the Standards do not have a significant
impact on a substantial number of small entities. The Standards use performance language
whenever possible to provide compliance flexibility to employers and to reduce the impact on
small businesses. Performance language may require small business employers to rely more
often than other employers on contractors to provide the safety and health technical expertise
necessary to comply with these requirements.
6. Describe the consequence to Federal program or policy activities if the collection is or is not conducted
less frequently, and any technical or legal obstacles to reducing the burden.
The Agency believes that the information collection frequencies required by the Standards are
the minimum frequencies necessary to effectively monitor employee exposure to electrical
hazards in construction and general industries, and thereby to fulfill its mandate “to assure so far
as possible every working man and woman in the Nation safe and healthful working conditions
and to preserve our human resources” as specified by the Act at 29 U.S.C. 651.
7. Explain any special circumstances that would cause an information collection to be conducted in a
manner:
9
•
Requiring respondents to report information to the agency more often than quarterly;
•
Requiring respondents to prepare a written response to a collection of information in fewer than 30
days after receipt of it;
•
Requiring respondents to submit more than an original and two copies of any document;
•
Requiring respondents to retain records, other than health, medical, government contract, grant-inaid, or tax records for more than three years;
•
In connection with a statistical survey that is not designed to produce valid and reliable results that
can be generalized to the universe of study;
•
Requiring the use of statistical data classification that has not been reviewed and approved by OMB;
•
That includes a pledge of confidentially that is not supported by authority established in statue or
regulation that is not supported by disclosure and data security policies that are consistent with the
pledge, or which unnecessarily impedes sharing of data with other agencies for compatible
confidential use; or
•
Requiring respondents to submit proprietary trade secret, or other confidential information unless
the agency can prove that it has instituted procedures to protect the information's confidentially to
the extent permitted by law.
No special circumstances exist that require employers to collect information using the procedures
specified by this item. The requirements are within the guidelines set forth in 5 CFR 1320.5.
8. If applicable, provide a copy and identify the date and page number of publication in the Federal Register
of the agency's notice, required by 5 CFR 1320.8(d), soliciting comments on the information collection before
submission to OMB. Summarize public comments received in response to that notice and describe actions
taken by the agency in response to those comments specifically address comments received on cost and hour
burdens.
Describe efforts to consult with persons outside the agency to obtain their views on the availability of data,
frequency of collection, the clarity of instructions and recordkeeping, disclosure, or reporting format (if any),
and on the data elements to be recorded, revealed, or reported.
Consultation with representatives of those from whom information is to be obtained or those who must
compile records should occur at least once every three years -- even if the collection of information activity is
the same as in prior periods. There may be circumstances that mitigate against consultation in a specific
situation. These circumstances should be explained.
As required by the Paperwork Reduction Act of 1995 (44 U.S.C. 3506(c)(2)(A)), OSHA
published a notice in the Federal Register on July 8, 2008 (73 FR 39049, Docket No. OSHA2008-0017) requesting public comment on its proposal to extend the information collection
requirements contained in its Electrical Standards for Construction (29 CFR part 1926, subpart
K) and for General Industry (29 CFR part 1910, subpart S). This notice was part of a
preclearance consultation program to provide those interested parties the opportunity to comment
on OSHA’s request for an extension by the Office of Management and Budget (OMB) of a
10
previous approval of the information collection requirements found in the Standard. The Agency
received no comments in response to its notice.
9. Explain any decision to provide any payments or gift to respondents, other than renumeration of
contractors or grantees.
The Agency will not provide payments or gifts to the respondents.
10. Describe any assurance of confidentiality provided to respondents and the basis for the assurance in
statute, regulation, or agency policy.
The paperwork requirements specified by these Standards do not involve confidential
information.
11. Provide additional justification for any questions of a sensitive nature, such as sexual behavior and
attitudes, religious beliefs, and other matters that are commonly considered private. This justification should
include the reasons why the agency considers the questions necessary, the specific uses to be made of the
information, the explanation to be given to persons from whom the information is requested, and any steps to
be taken to obtain their consent.
None of the provisions in the Standards require sensitive information.
12. Provide estimates of the hour burden of the collection of information. The statement should:
•
Indicate the number of respondents, frequency of response, annual hour burden, and an explanation
of how the burden was estimated. Unless directed to do so, agencies should not conduct special
surveys to obtain information on which to base hour burden estimates. Consultation with a sample
(fewer than 10) of potential respondents is desirable. If the hour burden on respondents is expected
to vary widely because of differences in activity, size, or complexity, show the range of estimated
hour burden, and explain the reasons for the variance. Generally, estimates should not include
burden hours for customary and usual business practices.
•
If this request for approval covers more than one form, provide separate hour burden estimates for
each form and aggregate the hour burdens in Item 13 of OMB Form 83-I.
•
Provide estimates of annualized cost to respondents for the hour burdens for collections of
information, identifying and using appropriate wage-rate categories.
Estimating Cost and Burden Hours
The following sections summarize the burden hour and cost determinations for the information
collection requirements specified by the Standards. The data is based on the final economic
analysis (FEA) prepared during the revision of the final rule for 29 CFR part 1910, subpart S, as
well as OSHA's estimate of the time it would take an employee to perform the necessary
electrical safety procedures.

TOTAL
The Agency has adopted the mean wage rates from “Occupational Employment and Wages, May
2006,” U.S. Department of Labor, Bureau of Labor Statistics, http://stats.bls.gov/home.htm.
Total compensation for these occupational categories includes an adjustment of 29.4 percent
(Employer Costs for Employee Compensation, September 2007, pp.4) for fringe benefits; this
figure represents the average level of fringe benefits in the private sector.
14
OSHA determined costs by multiplying the burden hours by the average compensation rates for
the year 2006 (including fringe benefits of 29.4 percent) for Standard Occupational
Classifications (SOCs) 17-2071 (electrical certified engineer), 17-3023 (electrical and electronic
engineering technician), and 11-9041 (engineering manager). The mean hourly wages for these
classifications are $37.93 (electrical certified engineer), $24.44 (electrical and electronic
engineering technician), and $52.90 (engineering manager) before fringe benefits. 4
The costs of labor used in this analysis are; therefore, estimates of total hourly compensation.
These hourly wages are:
Engineering Manager………………………………………………………….$68.45
Electrical Certified Engineer…………………………………………………..$49.08
Electrical and Electronic Engineering Technician (EEET)...………………….$31.63
Estimating the Number of Establishments and Employees
In the FEA of the final rule to revise 29 CFR Part 1910, subpart S, OSHA estimated the number
of establishments and employees affected by the rule. OSHA did not include in this FEA
estimate (or in this paperwork analysis) companies installing electrical systems and equipment
when the NEC is mandated by local or state jurisdictions. Accordingly, 43 of the 50 states
mandate the latest NEC (1999 or 2002 editions). In addition, 16 large cities outside of these
states have adopted the 1999 NEC, and three cities follow pre-1999 NECs. Based on its analysis
of the remaining employers (i.e., those employers not governed by states and cities mandating
the NEC), OSHA estimates that a total of .5 million establishments and 7.6 million employees
are affected by the Standards.
Construction Industries:
Based on the analysis, OSHA estimates that for every establishment affected, there will be an
average of nine jobsites (500,000 affected establishments x 9 jobsites = 4,500,000 jobsites).
Burden-Hour and Cost Determinations
§1926.403(h); 1910.303(f)(1)&(2)--Identification of disconnecting means and
circuits.
The burden for this requirement applies solely to employers in the construction industry because
the task occurs only during initial installation of motors and appliances. The only burden for
general industry is checking that the task has been done. The Agency assumes that only 1% of
the jobsites will need to mark and identify their system (1% of 4,500,000 jobsites = 45,000).
4
The average rates can be found at the following websites: http://www.bls.gov/oes/current/oes119041.htm,
http://www.bls.gov/oes/current/oes172071.htm, http://www.bls.gov/oes/current/oes173023.htm.
15
OSHA estimates that it takes an EEET five minutes (.08 hr.) to mark an average 30
disconnecting means or overcurrent devices usually found on a single panelboard at a jobsite.
Burden hours: 45,000 jobsites x .08 hour = 3,600 hours
Cost: 3,600 hours x $31.63 = $113,868
§1926.403(i)(2)(iii); 1910.303(g)(2)(iii)
Guarding of live parts (iii) Entrances to rooms and other guarded locations containing exposed
live parts shall be marked with conspicuous warning signs forbidding unqualified persons to
enter. The only burden for general industry is checking that the task has been done.
OSHA believes that it is usual and customary practice for employers to use the warning signs
repeatedly. These signs can be used from one location to another which reduces the burden of
constructing or ordering the sign. These reusable warning signs reduce the time and cost of
acquiring a new sign on the employer.
OSHA estimates that it will take 2 minutes (.03 hours) to acquire and post a warning sign. Only
5% of the jobsites will need to use new signs = 4,500,000 jobsites x .05 = 225,000
Burden hours: 225,000 jobsites x 1 sign x .03 = 6,750 hours
Cost: 6,750 hours x $31.63 = $ 213,503
§1926.403(j)(2)(ii); 1910.303(h)(2)(iii)(B)
Installations accessible to unqualified persons (ii) Electrical installations that are open to
unqualified persons shall be made with metal-enclosed equipment or shall be enclosed in a vault
or in an area, access to which is controlled by a lock. If metal-enclosed equipment is installed so
that the bottom of the enclosure is less than 8 feet above the floor, the door or cover shall be kept
locked. Metal-enclosed switchgear, unit substations, transformers, pull boxes, connection boxes,
and other similar associated equipment shall be marked with appropriate caution signs. If
equipment is exposed to physical damage form vehicular traffic, suitable guards shall be
provided to prevent such damage. Ventilating or similar openings will be deflected from
energized parts.
The caution signs are posted at the time the equipment is installed and therefore this requirement
is only done one time. The burden is taken in construction. The only burden for general industry
is checking that the task has been done.
OSHA estimates that it will take 2 minutes (.03 hours) to acquire and post the signs. Only 10%
of the jobsites will be affected (4,500,000 jobsites x .10 = 450,000).
Burden hours: 450,000 jobsites x 1 sign .03 hour = 13,500 hours
Cost: 13,500 hours x $31.63 = $427,005
16
§ 1926.404(b)(1)(iii)--Assured equipment grounding conductor (AEGC) program.
Regarding paragraph (b)(1)(iii)(A), OSHA estimates that 99% (4,455,000) of the construction
sites elect to use ground-fault circuit interrupters. The remaining 1% (45,000) jobsites use the
AEGC program. Assuming that existing contractors already have written AEGC programs, only
new contractors need to develop and implement such programs. OSHA estimates that it takes
one hour (1.00 hr.) for an EEET to develop an AEGC program. 4 Accordingly, the Agency
estimates that the total annual burden hours and cost of developing the written AEGC programs
are:
Burden hours: 45,000 jobsites x 1.00 hour = 45,000 hours
Cost: 45,000 hours x $31.63 = $1,423,350
In addition, paragraph (b)(1)(iii)(A) requires construction contractors to maintain the written
programs at the jobsite, and to disclose them on request to OSHA compliance officers and
affected employees. The Agency estimates that its compliance officers inspect 1.4% (630) of the
covered contractors each year, 5 during which they request access to the written programs.
OSHA estimates that it takes an EEET five minutes (.08 hour) to disclose the program to one of
its compliance officers during an inspection. The Agency also assumes that all 45,000 of the
AEGC programs are being maintained and that it will take one minute (.02 hour) per program for
this task.
Burden hours: (630 programs x .08 hour) + (45,000 jobsites x .02 hour) = 950 hours
Cost: 950 hours x $31.63 = $30,049
For paragraphs (b)(1)(iii)(E) and (b)(1)(iii)(G), OSHA believes that the 45,000 employers who
have AEGC programs test equipment and record the test results four times a year, and that it
takes an EEET three minutes (.05 hour) to perform each test and two minutes (.03 hour) to
record the test results, for a total test-and-record time of five minutes (.08 hour). Additionally,
the Agency estimates that it will inspect about 1.4% (630) of these programs each year, and
assumes that an EEET takes about two minutes (.03 hour) to disclose the written program to an
OSHA compliance officer.
4
Construction trade associations contacted by OSHA state that they provide preprinted AEGC programs to
employers to reduce the time required to develop an AEGC program to about one hour.
5
The Agency estimated the number of inspections by determining the inspection rate (1.4%) for all
establishments under the jurisdiction of the Act (including both federal OSHA and approved state-plan agencies),
then multiplied the total number of contractors using the AEGC program (45,000) by this percentage (i.e., 45,000 x
1.4% = 630 inspections.)
17
Burden hours:
Cost:
(45,000 AEGC programs x .08 hours x 4 times/year) + (630
inspections x .03 hours) = 14,419 hours
14,419 hours x $31.63 = $456,073
Total burden for AEGC program: 6
45,000 hours + 950 hours + 14,419 hours =
60,369 hours
Total cost:
$1,432,350 + $30,049 + $456,073 =
$1,909,472
§1926.404 (d)(2)(ii); §1910.304 (e)(2)(ii)
(d)(2) Services over 600 volts nominal. (ii) Warning signs. Signs warning of high voltage
shall be posted where other than qualified employees might come in contact with live parts.
The only burden for general industry is checking that the task has been done.
OSHA believes that it is usual and customary practice for employers to use the warning signs
repeatedly. These signs can be used from one location to another which reduces the burden of
constructing or ordering the sign. These reusable warning signs reduce the time and cost of
acquiring a new sign on the employer.
OSHA estimates that it will take three minutes (.05 hour) to acquire and post the warning sign.
Only 3% of the jobsites (135,000) will need to use new signs.
Burden hours: 135,000 jobsites x 1 sign x .05 hour = 6,750 hours
Cost: 6,750 hours x $31.63 = $213,503
§1926.405 (h); §1910.305 (h)(8)
Terminations (h): This paragraph applies to portable cables used at more than 600 volts
nominal. Termination enclosures shall be suitably marked with a high voltage hazard warning,
and terminations shall be accessible only to authorized and qualified employees.
The caution signs are posted at the time the equipment is installed. This requirement is done only
one time and; therefore, the burden is taken in construction. The only burden for general industry
is checking that the task has been done.
OSHA estimates that it will take 3 minutes (.05 hour) to acquire and post the sign. And only 5%
of the jobsites (225,000) will be affected.
Burden hours: 225,000 jobsites x 1 sign x .05 hour = 11,250 hours
Cost: 11,250 hours x $31.63 = $355,838

§1926.405 (j)(4)(ii)(A); §1910.305 (j)(4)(ii)-- Motors.
Disconnecting means (j)(4)(ii): An individual disconnecting means shall be provided for each
controller. A disconnecting means shall be located within sight of the controller location.
However, a single disconnecting means may be located adjacent to a group of coordinated
controllers mounted adjacent to each other on a multi-motor continuous process machine. The
controller disconnecting means for motor branch circuits over 600 volts, nominal, may be out of
sight of the controller, if the controller is marked with a warning label giving the location and
identification of the disconnecting means that is to be locked in the open position.
The burden for this task applies solely to employers in the construction industry because the task
occurs only during initial installation of controller-disconnecting means. The only burden for
general industry is checking that the task has been done.
OSHA estimates that it takes five minutes (.08 hour) for an EEET to construct and post a
warning label for each controller-disconnecting means, and that 2% of the new construction sites
(90,000) use these warning labels on a single controller-disconnecting means.
Burden hours: 90,000 jobsites x .08 hour = 7,200 hours
Cost: 7,200 hours x $31.63 = $227,736
§1926.405 (j)(5)(ii); §1910.305(j)(5)(ii)—Equipment for general use.
Transformer (j)(5)(ii): The operating voltage of exposed live parts of transformer installations
shall be indicated by signs or visible markings on the equipment or structure. The only burden
for general industry is checking that the task has been done.
The burden for this task applies solely to employers in the construction industry because the task
occurs only during initial installation. OSHA estimates that it takes three minutes (.05 hour) for
an EEET to acquire and post a warning sign, and that 5% of the construction sites (225,000) need
to use warning signs.
Burden hours: 225,000 jobsites x .05 hour = 11,250 hours
Cost: 11,250 hours x $31.63 = $355,838
§1926.405 (j)(6)(ii)(A); §1910.305(j)(6)(ii)(C)—Equipment for general use.
Capacitors (j)(6)(ii): Isolating or disconnecting switches (with no interrupting rating) shall be
interlocked with the load interrupting device or shall be provided with prominently displayed
caution signs to prevent switching load current; and The only burden for general industry is
checking that the task has been done.
OSHA estimates that it will take 3 minutes (.05 hour) to acquire and post the signs. Only 2% of
the jobsites (90,000) will be affected.
19
Burden hours: 90,000 jobsites x 1 sign x .05 hour = 4,500 hours
Cost: 4,500 hours x $31.63 = $142,335
§1926.408 (a)(2)(iii); 1910.305(a)(5)(vii)—Special Systems
Interrupting and isolating devices (a)(2)(iii) A means (for example, a fuseholder and fuse
designed for the purpose) shall be provided to completely isolate equipment for inspection and
repairs. Isolating means that are not designed to interrupt the load current of the circuit shall be
either interlocked with an approved circuit interrupter or provided with a sign warning against
opening them under load. The only burden for general industry is checking that the task has been
done.
OSHA estimates that it will take 3 minutes (.05 hrs) to acquire and post the warning sign. Only
1% of the jobsites will need to use new signs = 4,500,000 jobsites x .01 = 45,000
Burden hours: 45,000 jobsites x 1 sign .05 hour = 2,250 hours
Cost: 2,250 hours x $31.63 = $71,168
§1926.408 (a)(3)(i); 1910.305(a)(6)(i)—Special Systems
Mobile and portable equipment (a)(3)(i) A metallic enclosure shall be provided on the mobile
machine for enclosing the terminals of the power cable. The enclosure shall include provisions
for a solid connection for the grounding terminal to effectively ground the machine frame. The
method of cable termination used shall prevent any strain or pull on the cable from stressing the
electrical connections. The enclosure shall have provision for locking so only authorized
qualified persons may open it and shall be marked with a sign warning of the presence of
energized parts.
OSHA believes that it is a usual and customary practice for employers to use the warning signs
repeatedly. These signs can be used from one location to another which reduces the burden of
constructing or ordering the sign. These reusable warning signs reduce the time and cost of
acquiring a new sign on the employer.
OSHA estimates that it will take 2 minutes (.03 hour) to acquire and post the warning sign. Only
2% of the jobsites (90,000) will need to use new signs.
Burden hours: 90,000 jobsites x 1 sign x .03 hour x = 2,700 hours

§1926.408 (a)(3)(ii); §1910.305(a)(6)(ii)— Special Systems
Mobile and portable equipment--(a)(3)(ii): All energized switching and control parts shall be
enclosed in effectively grounded metal cabinets or enclosures. Circuit breakers and protective
equipment shall have the operating means projecting through the metal cabinet or enclosure so
these units can be reset without locked doors being opened. Enclosures and metal cabinets shall
be locked so that only authorized qualified persons have access and shall be marked with a sign
warning of the presence of energized parts. Collector ring assemblies on revolving-type
machines (shovels, draglines, etc.) shall be guarded.
OSHA believes that it is a usual and customary practice for employers to use the warning signs
repeatedly. These signs can be used from one location to another which reduces the burden of

Burden hours: 90,000 jobsites x 1 sign x .03 hour = 2,700 hours
Cost: 2,700 hours x $31.63 = $85,401
§1926.416 (a)(3)—General requirements
Before work is begun, the employer shall ascertain by inquiry or direct observation, or by
instruments, whether any part of an energized electric power circuit, exposed or concealed, is so
located that the performance of the work may bring any person, tool, or machine into physical or
electrical contact with the electric power circuit. The employer shall post and maintain proper
warning signs where such a circuit exists. The employer shall advise employees of the location
of such lines, the hazards involved, and the protective measures to be taken.
These warning signs and marks alert unqualified and unauthorized employees of the presence of
electrical hazards, and notify electricians of the need to exercise caution and to take other
measures to protect themselves when they are near electrical hazards.
OSHA estimates that it will take 2 minutes (.03 hour) to acquire and post the warning sign. Only
2% of the jobsites (90,000) will need to use new signs.
Burden hours: 90,000 jobsites x 1 sign x .03 hour = 2,700 hours
Cost: 2,700 hours x $31.63 = $85,401
§1926.417 (a), (b),& (c)--Lockout and tagging of circuits
Controls: (a) Controls that are to be deactivated during the course of work on energized or
deenergized equipment or circuits shall be tagged.
21
Equipment and circuits: (b) Equipment or circuits that are deenergized shall be rendered
inoperative and shall have tags attached at all points where such equipment or circuits can be
energized.
Tags: (c) Tags shall be placed to identify plainly the equipment or circuits being worked on.
The Agency assumes that contractors tag one electrical hazard at each jobsite, and that an
electrician spends one minute (.02 hour) tagging each hazard. OSHA estimates that only 5% of
the jobsites (225,000) will need to use lockout and tagging.
Burden hours: 225,000 jobsites x 1 tags x .02 hour = 4,500 hours
Cost: 4,500 hours x $31.63 = $142,335
General Industry:
Based on the analysis of the total number of establishments, only the new installations will be
affected. OSHA estimates that only 1% of the affected establishments will be new (i.e., 500,000
establishments x 1% = 5,000 new establishments).
§1910.303(f) -- Disconnecting means and circuits
Paragraph (f)(5)(i)--Where circuit breakers or fuses are applied in compliance with the series
combination ratings marked on the equipment by the manufacturer, the equipment enclosures
shall be legibly marked in the field to indicate that the equipment has been applied with a series
combination rating.
Paragraph (f)(5)(ii)--The marking required by paragraph (f)(5)(i) of this section shall be readily
visible and shall state "Caution -- Series Combination System Rated_____Amperes. Identified
Replacement Component Required."
Since this information is readily available to employers (i.e., provided on the equipment by the
manufactures), OSHA estimates that an EEET takes two minutes (.03 hour) to determine the
series-combination ratings on the equipment and mark the ampere rating of the system in the
designated space. In addition, the Agency estimates that 75% (3,750) of the new establishments
need to mark the ampere ratings (5,000 new establishments x .75 = 3,750 new establishments),
and that each new establishment needs to mark one equipment enclosure. Accordingly, the total
yearly burden hour and cost estimates resulting from this requirement are:
Burden hours: 3,750 new installations x .03 hour = 113 hours
Cost: 113 hours x $31.63 = $3,574
22
§1910.304(b) -- Branch circuits
Identification of multiwire branch circuits (b)(1)--Where more than one nominal voltage
system exists in a building containing multiwire branch circuits, each ungrounded conductor of a
multiwire branch circuit, where accessible, shall be identified by phase and system. The means
of identification shall be permanently posted at each branch-circuit panelboard.
Since this information is readily available to employers (i.e., provided on the equipment by the
manufacturer), OSHA estimates that it takes an EEET approximately one minute (.02 hour) to
mark the phase and system of each ungrounded conductor. The Agency also estimates that 75%
(3,750) of the new establishments need to perform this task (i.e., mark one ungrounded
conductor). Thus, the total annual burden hours and cost estimated for this requirement are:
Burden hours: 3,750 new establishments x .02 hour = 75 hours
Cost: 75 hours x $31.63 = $2,372
Ground-fault circuit interrupter protection for personnel (b)(3)(ii)(C)(1)--A written
description of the program, including the specific procedures adopted by the employer, shall be
available at the jobsite for inspection and copying by the Assistant Secretary of Labor and any
affected employee;
Assuming that 99.97% of the establishments will use ground-fault circuit-interrupter protection
and; therefore, are not eligible to use an AEGC program, then the Agency estimates that .03%
(150) of the establishments will use a written AEGC program (500,000 establishments x .0003 =
150 establishments). Based on information obtained from construction-trade associations,
employers are provided with preprinted AEGC programs that reduce program development time.
OSHA estimates that an EEET will take one hour to develop a written AEGC program. The total
burden hours and cost of the development of this program is:
Burden hours: 150 establishments x 1 hour = 150 hours
Cost: 150 hours x $31.63 = $4,745
This provision also requires employers to maintain the written AEGC programs at the jobsite,
and to disclose the programs to OSHA compliance officers and affected employees. The Agency
estimates that an EEET requires one minute (.02 hour) each year maintaining written program.
Additionally, OSHA determines that compliance officers inspect 1.4% of the establishments
having written AECG programs annually (1.4 x 150 establishments = 2 inspections; see Item 14
for an explanation of the inspection rate). The Agency also assumes that it takes an EEET two
minutes (.03 hour) to disclose the written program to a compliance officer during each of these
inspections.
Based on these estimates, the total time for an EEET to maintain the program is .02 hour and to
disclose a written AEGC program is .03 hour to the compliance officer. Therefore, the Agency
23
estimates that the total annual burden hours and cost for these information collection
requirements are:
Burden hours: 150 establishments x .05 hour = 8 hours
Cost: 8 hours x $31.63 = $253
Paragraph (b)(3)(ii)(C)(6)--Tests performed as required in paragraph (b)(3)(ii)(C) of this section
shall be recorded. This test record shall identify each receptacle, cord set, and cord- and plugconnected equipment that passed the test and shall indicate the last date it was tested or the
interval for which it was tested. This record shall be kept by means of logs, color coding, or
other effective means and shall be maintained until replaced by a more current record. The
record shall be made available on the jobsite for inspection by the Assistant Secretary and any
affected employee.
OSHA believes that the 150 establishments with written AEGC programs test equipment and
record the test results four times a year. It also estimates that an EEET takes three minutes (.05
hour) to perform each test and two minutes (.03 hour) to record the test results, for a total testand record time of five minutes (.08 hour). These requirements result in total annual burden hour
and cost estimates of:
Burden hours: 150 establishments x 4 tests/year x .08 hour = 48 hours
Cost: 48 hours x $31.63 = $1,518
Total burden hours for AEGC programs: 150 hours + 8 hours + 48 hours = 206 hours
Total cost: $4,745 + $253 + $1,518 = $6,516
§1910.306(c) -- Specific purpose equipment and installations.
Paragraph (6)(i)--Where there is more than one driving machine in a machine room, the
disconnecting means shall be numbered to correspond to the identifying number of the driving
machine that they control.
In meeting this requirement, OSHA estimates that identifying and correctly numbering the
disconnecting means takes an EEET eight minutes (.13 hour), and that 20% (1,000) of the new
establishments must perform this task (5,000 new establishments x .20 = 1,000 new
establishments). Accordingly, the estimated total annual burden hours and cost for this
requirement is:
Burden hours: 1,000 new establishments x .13 hour = 130 hours
Cost: 130 hours x $31.63 = $4,112
Paragraph (6)(ii)--The disconnecting means shall be provided with a sign to identify the location
of the supply-side overcurrent protective device.
24
OSHA assumes that all new establishments must provide one sign to identify the location of the
supply-side overcurrent protective device, and that an EEET performs this task in eight minutes
(.13 hour). This requirement results in the following total annual burden hour and cost estimates:
Burden hours: 5,000 new establishments x .13 hour = 650 hours
Cost: 650 hours x $31.63 = $20,560
▪
§1910.306(k) --- Carnivals, circuses, fairs, and similar events
Paragraph (4)(iv)(B)--Single-pole separable connectors used in portable professional motion
picture and television equipment may be interchangeable for ac or dc use or for different current
ratings on the same premises only if they are listed for ac/dc use and marked to identify the
system to which they are connected;
The Agency estimates that .5% (25) of the new establishments use interchangeable single-pole
separable connectors in portable professional motion pictures and television equipment (5,000
new establishments x .005 = 25 new establishments), and that an EEET requires eight minutes
(.13 hour) to list the connectors for ac/dc use and mark them to identify the system to which they
are connected. Therefore, OSHA estimates the total annual burden hours and cost of this
requirement is:
Burden hours: 25 new establishments x .13 hour = 3 hours
Cost: 3 hours x $31.63 = $95
§1910.307(b) -- Documentation
Paragraph (b)--All areas designated as hazardous (classified) locations under the Class and Zone
system and areas designated under the Class and Division system established after August 13,
2007 shall be properly documented. This documentation shall be available to those authorized to
design, install, inspect, maintain, or operate electric equipment at the location.
This documentation consists of area-classification drawings that provide information for
designers, installers, inspectors, and other personnel who must ensure that electrical equipment
installed and maintained at hazardous (classified) locations meets the certification requirements
specified elsewhere in the Standard. The Agency assumes that 40% (2,000) of the new
establishments will require this documentation (5,000 new establishments x .4 = 2,000 new
establishments) for one of these locations, and that an electrical certified engineer takes four
hours to produce this documentation. Consequently, the estimated total annual burden hours and
cost for this documentation are:
Burden hours: 2,000 new establishments x 4 hours = 8,000 hours
Cost: 8,000 hours x $49.08 = $392,640
25
§1910.308(b) -- Emergency power system
Paragraph (b)(3)(i)--A sign shall be placed at the service entrance equipment indicating the type
and location of on-site emergency power sources. However, a sign is not required for individual
unit equipment.
According to OSHA’s estimates, an engineering manager takes one minute (.02 hour) to brief an
EEET about the required task, and five minutes (.08 hour) for the EEET to acquire and place the
sign. The Agency assumes that 30% (1,500) of the new establishments must acquire and place
one of these signs (5,000 new establishments x .3 = 1,500 new establishments). The resulting
annual total burden hour and cost estimates are:
Burden hours: 1,500 new establishments x .02 hour = 30 hours
1,500 new establishments x .08 hour = 120 hours
Total burden hours: 150 hours
Cost: 30 hours x $68.45 = $2,054
120 hours x $31.63 = $3,796
Total cost: $5,850
Paragraph (b)(3)(ii)--Where the grounded circuit conductor connected to the emergency source is
connected to a grounding electrode conductor at a location remote from the emergency source,
there shall be a sign at the grounding location that shall identify all emergency and normal
sources connected at that location.
To meet this requirement, the Agency estimates that an engineering manager takes one minute
(.02 hour) to brief an EEET regarding the required task, and five minutes (.08 hour) for the
EEET to acquire and place the sign. OSHA believes that 2% (100) of the new establishments
must acquire and place one of these signs (5,000 new establishments x .02 = 100 new
establishments). The Agency estimates the annual total burden hours and cost of this
requirement to be:
Burden hours: 100 new establishments x .02 hour = 2 hours
100 new establishments x .08 hour = 8 hours
Total burden hours: 10 hours
Cost: 2 hours x $68.45 = $137
8 hours x $31.63 = $253
Total cost: $390
1910.333--Selection and use of work practices.
Procedures. Paragraph 1910.333(b)(2)(i) requires employers to maintain a written copy of the
procedure outlined in paragraph (b)(2) of this standard, and to make it available for inspection by
26
employees and by the Assistant Secretary of Labor and his/her authorized representatives. The
written procedures may be a copy of paragraph (b) of this standard.
OSHA estimates that it will take 15 minutes (.25 hours) to record and maintain a written copy of
the procedure outlined in requirement. Only 85% of the establishment will need a written copy
of the procedure to use for tagging (.85 x 5,000 establishments = 4,250).
Burden hours: 4,250 new establishments x 1 procedure x .25 hour = 1,063
hours
Cost: 1,063 hours x $31.63 = $33,623
Application of locks and tags. Paragraph 1910.333(b)(2)(iii)(B) requires employers to ensure
that each tag used contains a statement prohibiting unauthorized operation of the disconnecting
means and removal of the tag.
These tags alert unqualified and unauthorized employees of the presence of electrical hazards,
and notify other employee in the vicinity of the need to exercise caution when they are near
electrical hazards.
The Agency assumes that each establishment will use one tag for each system and that an
electrician spends three minutes (.05 hour) tagging each disconnect. OSHA estimates that only
85% of the establishment (4,250) will need to use lockout and tagging (.85 x 5,000
establishments = 4,250
Burden hours: 4,250 new establishments x 1 tags x .05 hour = 213 hours
Cost: 213 hours x $31.63 = $6,737
Paragraph 1910.333(b)(2)(v)(B) requires employers to warn employees exposed to the hazards
associated with reenergizing the circuit or equipment to stay clear of the circuits and equipment.
These warning signs and marks alert unqualified and unauthorized employees of the presence of
electrical hazards, and notify electricians of the need to exercise caution and to take other
measures to protect themselves when they are near electrical hazards.
OSHA estimates that it will take five minutes (.08 hour) to acquire and post the warning sign.
Only 15% of the jobsites (45,000 jobsites x .15 = 6,750) will need to use new signs.
Burden hours: 6,750 jobsites x 1 sign x .08 hour = 540 hours
Cost: 540 hours x $31.63 = $17,080
13. Provide an estimate of the total annual cost burden to respondents or recordkeepers resulting from the
collection of information. (Do not include the cost of any hour burden shown in Items 12 and 14.)
•
The cost estimate should be split into two components: (a) a total capital and start-up cost
component annualized over its expected useful life); and (b) a total operation and maintenance and
27
purchase of service component. The estimates should take into account costs associated with
generating, maintaining, and disclosing or providing the information. Include descriptions of
methods used to estimate major cost factors including system and technology acquisition, expected
useful life of capital equipment, the discount rate(s), and the time period over which costs will be
incurred. Capital and start-up costs include, among other items, preparations for collecting
information such as purchasing computers and software; monitoring, sampling, drilling and testing
equipment; and record storage facilities.
•
If cost estimates are expected to vary widely, agencies should present ranges of cost burdens and
explain the reasons for the variance. The cost of purchasing or contracting out information
collection services should be a part of this cost burden estimate. In developing cost burden estimates,
agencies may consult with a sample of respondent (fewer than 10), utilize the 60-day pre-OMB
submission public comment process and use existing economic or regulatory impact analysis
associated with the rulemaking containing the information collection, as appropriate.
•
Generally, estimates should not include purchases of equipment or services, or portions thereof,
made: (1) prior to October 1, 1995, (2) to achieve regulatory compliance with requirements not
associated with the information collection, (3) for reasons other than to provide information or keep
records for the government, or (4) as part of customary and usual business or private practices.
Capital Cost Determinations
As noted under section B of Item 12 above, OSHA estimated that §1910.304(b)(1) requires 75%
(3,750) of the new establishments to label the phase and system of one ungrounded conductor a
year. Therefore, these establishments must purchase a total of 3,750 labels to complete this task.
The Agency assumes that each label costs $2.00. Accordingly, the total cost each year to these
employers is:
Cost: 3,750 labels x $2.00 = $7,500
14. Provide estimates of the annualized cost to the Federal Government. Also, provide a description of the
method used to estimate cost, which should include quantification of hours, operational expenses (such as
equipment, overhead, printing, and support staff), any other expense that would not have been incurred
without this collection of information. Agencies also may aggregate cost estimates from Items 12, 13, and 14
into a single table.
OSHA estimates that a compliance officer (GS-12, step 5), with an hourly wage rate of $37.89,
spends about five minutes (.08 hr.) during an average inspection reviewing the information
collections required by the Standards. The Agency estimates compliance officers inspect about
630 firms/employers regulated by the Standards during each year covered by this ICR. 7
However, an average inspection for an AEGC program might take 10 minutes (.17 hour) to
review the information collections required by the standard. OSHA considers other expenses,
such as equipment, overhead, and support staff salaries, to be normal operating expenses that
7
The Agency estimated the number of inspections by determining the inspection rate (1.4%) for all
establishments under the jurisdiction of the Act (including both federal OSHA and approved state-plan agencies),
and then multiplied the total number of firms/employers affected by these Standards by this percentage (i.e.,
4,500,000 jobsites/employers x 1.4% = 63,000 jobsites/employers).
28
would occur without the paperwork requirements specified by the Standards. Therefore, the total
cost of these paperwork requirements to the Federal government is:
Cost in construction:
(63,000 total inspections – 630 AEGC inspections) = 62,370 inspections
62,370 inspections x .08 hour x $37.89 =
630 AEGC inspections x .17 hour x $37.89 =
Total
$189,056
$ 4,058
$193,114
Cost in general industry:
70 inspections – 2 AEGC inspections) = 68 inspections
68 inspections x .08 hour x $37.89=
2 AEGC inspections x .17 hour x $37.89=
Total cost:
$212
$ 13
$225
Total cost in both industries: $193,114 + $225 = $193,339
15. Explain the reasons for any program changes or adjustments reported in Items 13 or 14 of the OMB
Form 83-1
OSHA is proposing to increase the existing burden hour estimate of the information collection
requirements specified by the Standards. In this regard, the Agency is proposing to combine the
Electrical Standards for both construction (1218-0130) and general industry (1218-0256). The
construction standards current burden hours are 83,291 and the general industry current burden
hours are 9,353 totaling 92,644 hours for both. This will increase the current burden hour
estimate from 92,644 hours to 151,172 hours, a total increase of 58,528 hours. See Table 2
below which describes each of the proposed burden hour adjustments.
16. For collections of information whose results will be published, outline plans for tabulation, and
publication. Address any complex analytical techniques that will be used. Provide the time schedule for the
entire project, including beginning and ending dates of the collection information, completion of report,
publication dates, and other actions.
OSHA will not publish the information collected under the Standards.
17. If seeking approval to not display the expiration date for OMB approval of the information collection,
explain the reasons that display would be appropriate.
No forms are available for the Agency to display the expiration date.
18. Explain each exception to the certification statement identified in Item 19 per "Certification for
Paperwork Reduction Act Submission," of OMB Form 83-I.
29
OSHA is not seeking an exception to the certification statement specified by Item 19 of OMB
83-I.
