Electric Power Generation, Transmission, and Distribution;

Electrical Protective Equipment; Final Rule; Stay of Enforcement and

Correction

AGENCY: Occupational Safety and Health Administration (OSHA),

Department of Labor.

ACTION: Final rule; stay of enforcement and correction.

-----------------------------------------------------------------------

SUMMARY: On January 31, 1994, OSHA issued a new standard addressing the

work practices to be used during the operation and maintenance of

electric power generation, transmission, and distribution facilities

[59 FR 4320]. In that document, OSHA also revised the electrical

protective equipment requirements contained in the General Industry

Standards. This notice stays the enforcement of some of the

requirements contained in the electric power generation standard,

corrects language in the preamble explaining the standard, and corrects

several errors in the standards.

DATES: OSHA is staying the enforcement of the following paragraphs of

Sec. 1910.269 until November 1, 1994: (b)(1)(ii), (d) except for

(d)(2)(i) and (d)(2)(iii), (e)(2), (e)(3), (j)(2)(iii), (l)(6)(iii),

(m), (n)(3), (n)(4)(ii), (n)(8), (o) except for (o)(2)(i), (r)(1)(vi),

(u)(1), (u)(4), (u)(5). OSHA is also staying the enforcement of

paragraphs (n)(6) and (n)(7) of Sec. 1910.269 until November 1, 1994,

but only insofar as they apply to lines and equipment operated at 600

volts or less. Further, OSHA is staying the enforcement of paragraph

(v)(11)(xii) of Sec. 1910.269 until February 1, 1996.

The corrections to Sec. 1910.269 presented in this document become

effective on June 30, 1994.

FOR FURTHER INFORMATION CONTACT: Mr. James F. Foster, U.S. Department

of Labor, Occupational Safety and Health Administration, Room N3647,

200 Constitution Ave., N.W., Washington, D.C. 20210 (202-219-8148).

SUPPLEMENTARY INFORMATION: On January 31, 1994, OSHA issued a new

standard addressing the work practices to be used during the operation

and maintenance of electric power generation, transmission, and

distribution facilities. In that document, OSHA also revised the

electrical protective equipment requirements contained in the General

Industry Standards.

I. Correction of the Preamble: Clothing for Employees Working On or

Near Exposed Energized Parts

Paragraph (l)(6)(iii) of Sec. 1910.269 prohibits employees exposed

to flames or arcs from wearing clothing that, when exposed to flames or

arcs, could increase the extent of injury that would be sustained by

the employees. In adopting this requirement in the final rule, OSHA

relied on the evidence submitted to the record in determining what

clothing would or would not be acceptable under the language of

paragraph (l)(6)(iii). The preamble to the final rule discussed a

portion of this evidence as follows:

The requirement is intended to prohibit the types of fabrics

shown in the Duke Power Company videotape to be expected to cause

more severe injuries than would otherwise be anticipated. These

include such untreated materials as polyester and rayon, unless the

employee is otherwise protected from the effects of their burning.

Natural fabrics, such as 100 percent cotton or wool, and synthetic

materials that are flame resistant or flame retardant are acceptable

under the final rule. (If and when a national consensus standard on

clothing for electrical workers becomes available, OSHA will examine

whether or not to revise the rule to require materials conforming to

such a standard.) [59 FR 4389]

It is clear from this discussion that OSHA relied heavily on the

videotape produced by Duke Power Company and on the results of arc

tests on clothing as shown in the videotape in its finding that

clothing made from certain fabrics was prohibited and that clothing

made from other fabrics was acceptable. It is also quite clear from the

preamble quotation that the Agency intended the final rule ``to

prohibit the types of fabrics shown in the Duke Power Company videotape

to be expected to cause more severe injuries than would otherwise be

anticipated.'' However, later in that same quotation, OSHA stated that

``natural fabrics, such as 100 percent cotton or wool, and synthetic

materials that are flame resistant or flame retardant are acceptable

under the final rule.'' Several questions have been raised in the

period after the promulgation of the rule in regard to this statement

in the preamble. Interested parties have pointed out that the Duke

videotape stated specifically:

All the heavyweight natural fibers we tested performed well.

Natural fibers are those found in nature, such as cotton, wool,

silk, and linen. We did little testing with silk and linen since

most people wouldn't wear them while doing electrical work, but we

performed extensive tests with cottons and wools. Lightweight

cottons and wools sometimes burned, but without the melting and

sticking of synthetics. Heavyweight cottons, wools, and blends of

the two did not burn. They actually seemed to insulate whatever they

were covering from the heat of the arc. Heavyweight means that a

material weighs at least 11 ounces per yard, like the fabric in a

denim jacket.

OSHA wrote Sec. 1910.269(l)(6)(iii) in performance-oriented

language. That language prohibits any clothing that, when exposed to

flame or arc, could increase the extent of injury sustained by an

employee. Although the record that was in place when final

Sec. 1910.269 was adopted did not provide sufficient information for

the adoption of a rule specifying clothing that would actually protect

an employee from both flames and arcs, the Agency concluded that the

record did support a rule prohibiting clothing that could further

injure a worker. In other words, OSHA adopted a rule that addresses

whether or not the clothing worn by a worker would contribute to injury

rather than a rule requiring personal protective equipment. As a

result, to determine whether clothing made from a given material meets

the standard, OSHA need only ascertain whether that material will

ignite and continue to burn under the conditions to which an employee

is exposed. If, under these conditions, a material will ignite and will

continue to burn in the absence of an ignition source, then clothing

made from such material is prohibited by Sec. 1910.269(l)(6)(iii),

unless the clothing is worn in such a manner as to eliminate the hazard

involved.

The Duke videotape, which was the primary basis for OSHA's

determination that clothing made from certain types of fabrics should

be prohibited whenever an employee is exposed to the hazards of

electric arc, states that clothing made from 11-ounce cotton would not

ignite under the conditions present during their arc tests. Clothing

made from lesser weights of cotton could ignite and, once ignited,

would continue to burn after the arc ceased. Clearly, from this

evidence in the rulemaking record, clothing made from cotton of less

than 11 ounces will not meet the performance criteria given in the

standard for employees exposed to conditions comparable to those in the

Duke Power Company tests.1 Cotton of 11 ounces or more will not

ignite and therefore does meet the requirement in

Sec. 1910.269(l)(6)(iii) under the arc test conditions.

---------------------------------------------------------------------------

\1\The conditions present during the Duke Power Company tests

involved an 3800-ampere, 12-inch (approximate) electric arc that was

approximately 12 inches from the material. The arc lasted for 10

cycles, or 0.167 seconds.

---------------------------------------------------------------------------

On the basis of this evidence in the rulemaking record, OSHA has

concluded that clothing made from 100 percent cotton or wool will be

acceptable if its weight is appropriate for the flame and electric arc

conditions to which an employee could be exposed. Employers must make a

determination of whether or not 100 percent cotton or wool clothing

worn by a worker is acceptable under the conditions to which he or she

could be exposed. The factors employers must consider in making this

determination are: The weight of the material; the available current

involved; the duration of exposure; the distance from any possible

flames or arcs that might occur; and the presence of other flammable

materials (such as flammable hydraulic fluid) that could be ignited in

the presence of an arc and, in turn, ignite the clothing. Later in this

document, OSHA is correcting the quoted sentence in the preamble to the

final rule in order to clarify the Agency's intent in this matter. (It

should be noted that OSHA is not revising either the rule in paragraph

(l)(6)(iii) or the note following that paragraph. The fabrics listed in

that note continue to be prohibited.)

Clothing made from flame-retardant or flame-resistant materials is

acceptable under the rule. Employers are encouraged to ensure that

their employees wear such clothing if they will be exposed to the

hazard of flame or electric arc. In this regard, it should also be

noted that the American Society for Testing and Materials (ASTM) has

adopted a new standard, ASTM F1506-1994, for clothing to be worn for

the protection of electrical workers who could be exposed to the hazard

of flame or electric arc. This standard, which has not yet incorporated

an arc-resistance test, requires the fabric used in clothing to pass a

vertical flame test (that is, the fabric must be flame retardant or

flame resistant). In fact, when OSHA revises Sec. 1910.269 or its

counterpart in the Construction Standards (Subpart V of Part 1926), the

Agency will be required under the Occupational Safety and Health Act of

1970 (OSH Act) to adopt a rule that, if it differs substantially from

the ASTM standard, must better effectuate the purposes of the OSH Act

than that consensus standard. Employers should keep these facts in mind

when adopting rules relating to the clothing worn by their electric

power generation, transmission, and distribution employees.

OSHA will continue to encourage ASTM Committee F18 (the committee

responsible for ASTM F 1506) to expedite their research and standards

development activities with regard to protective clothing worn by

electrical workers. The Agency will use the latest information

available from the committee and from other sources in revising

Sec. 1910.269(l)(6)(iii) in the future.

II. Stay of Enforcement of Certain Provisions of Sec. 1910.269

The electrical protective equipment standard and the electric power

generation, transmission, and distribution standard, except

Sec. 1910.269(a)(2), became effective on May 31, 1994. The Edison

Electric Institute (EEI) petitioned OSHA to delay the effective date of

certain requirements of these two standards until January 31, 1995,

when the training requirements of Sec. 1910.269(a)(2) become effective.

It said that several provisions require the purchase of equipment that

is not in sufficient supply for the entire universe of affected

employers. EEI also contended that other provisions require the

modification of equipment or installations and that employers will need

more than the 120 days given in the notice of rulemaking to make these

modifications. It asserted that still other requirements entail

significant departure from normal company practice and that detailed

training is required to implement these requirements. The general

training requirements, it noted, do not become effective until January

31, 1995. Lastly, it maintained that employers need more time to

consult with OSHA to determine exactly what practices and procedures

are acceptable under the new standards.

OSHA has reviewed EEI's petition for delay in the effective date

and has found it justified, in part. With respect to EEI's petition

regarding requirements that necessitate the purchase of equipment that

is in short supply, the Agency finds that it is unnecessary to provide

any delay in enforcement of these requirements. It is OSHA policy to

accept purchase orders dated before the effective date of a standard to

be evidence of intent to comply with that standard. In such cases, the

Agency does not issue citations or impose penalties on companies that

have ordered but not yet received goods that are intended for

compliance with OSHA requirements.

A stay will be necessary for provisions requiring significant

modifications in equipment or installations. If an alteration is

necessary, these requirements will force an employer to plan and design

the modification, purchase any necessary materials, and then install

the appropriate modification. These adjustments will normally take more

than the 120 days given in the notice of rulemaking to put into place.

EEI has identified one provision requiring modifications to

existing coal-handling installations that will take up to 2 years for

employers to effectuate. Paragraph (v)(11)(xii) of Sec. 1910.269

requires sources of ignition to be eliminated or controlled so as to

prevent the ignition of combustible atmospheres associated with coal-

handling operations. EEI argues that extensive modifications will be

necessary at many older power plants and that these changes will take

up to 2 years to put into place.

Therefore, a stay of enforcement of Sec. 1910.269(v)(11)(xii) is

granted until February 1, 1996, and a stay of enforcement of the

following paragraphs of Sec. 1910.269 is granted until November 1,

1994:

------------------------------------------------------------------------

Paragraph Description

------------------------------------------------------------------------

(e)(3)............................. Rescue equipment for enclosed

spaces.

(u)(1)............................. Access and working space for

electric equipment in substations.

(u)(4)............................. Guarding of rooms containing

electric supply equipment in

substations.

(u)(5)............................. Guarding of energized parts in

substations.

------------------------------------------------------------------------

With respect to provisions that entail extensive changes in work

practices or procedures necessitating substantial retraining of

employees, OSHA agrees to delay enforcement until the training for any

new practices or procedures can be completed for all affected

employees. Having some employees, who have been trained in a new

procedure, use that procedure while other employees, who are not

familiar with the new procedure, use other work methods could provide

less safety. For example, the lockout and tagging requirements of

Sec. 1910.269(d) necessitate the adoption of specific procedures for

the control of hazardous energy sources. OSHA anticipates that some

employers will need to modify existing lockout and tagging procedures

to effect compliance with paragraph (d). Although the Agency believes

that most affected employers are already using programs for the control

of hazardous energy sources, some employers may need to modify their

practices to comply with the final rule and to protect their employees

fully. However, if those modifications are put into effect before all

employees have been trained in their use, errors and injuries could

result. Additionally, some of the provisions that EEI identified as

requiring substantial training efforts are specific training

requirements. For example, Sec. 1910.269(e)(2) requires employees to be

trained in the hazards of enclosed space entry, in enclosed space entry

procedures, and in enclosed space rescue procedures. These provisions

will also take longer than 120 days to implement.

Therefore, for this reason, OSHA is staying the enforcement of the

following paragraphs of Sec. 1910.269 until November 1, 1994:

------------------------------------------------------------------------

Paragraph Description

------------------------------------------------------------------------

(b)(1)(ii)......................... Training in cardio-pulmonary

resuscitation for employees at

fixed work locations.

(d), except for (d)(2)(i) and (d) Control of hazardous energy sources

(2) (iii). (generation installations).

(e)(2)............................. Enclosed space training.

(j)(2)(iii)........................ Cleaning, repair, and testing of

live-line tools.

(m)................................ Deenergizing transmission and

distribution installations for the

protection of employees.

(o), except for (o)(2)(i).......... High-voltage and high-power testing

and test facilities.

------------------------------------------------------------------------

The remaining requirements for which EEI requested delay are those

that it claims will need additional consultation with OSHA so that

employers will know exactly what is required by the standard. Because

the standard is written in terms of performance, rather than in terms

specifying the means of compliance, employers are given flexibility in

meeting the standard. However, sometimes it may not be clear whether or

not a given method will comply with an individual provision. For

example, employers will likely need more time to identify the types of

clothing that will be acceptable under Sec. 1910.269(l)(6)(iii).

Therefore, OSHA is staying the enforcement of the following

paragraphs of Sec. 1910.269 until November 1, 1994:

------------------------------------------------------------------------

Paragraph Description

------------------------------------------------------------------------

(1)(6)(iii)........................ Clothing worn by employees working

on or near exposed energized

parts.

(n)(3)............................. Equipotential zone for protective

grounding.

(n)(4)(ii)......................... Impedance of protective grounding

devices.

(n)(6)\1\.......................... Order of connection of grounds.

(n)(7)\1\.......................... Order of removal of grounds.

(n)(8)............................. Additional precautions for

protective grounding.

(r)(1)(vi)......................... Line-clearance tree trimming during

and after storms and other

emergencies.

------------------------------------------------------------------------

\1\Only with respect to lines and equipment operating at 600 volts or

less.

OSHA emphasizes that the record is not being reopened on any of the

delayed provisions of Sec. 1910.269. Revised Sec. 1910.137 and

Sec. 1910.269 are final rules, and the Agency is not considering the

modification of any of these requirements. Additionally, Sec. 1910.137

and all paragraphs of Sec. 1910.269 other than paragraph (a)(2), which

becomes effective on January 31, 1995, went into effect on May 31,

1994, as scheduled.

PART 1910--[AMENDED]

For the reasons set forth above, the following Note is added to

Sec. 1910.269 immediately preceding the text of the section.

Sec. 1910.269 Electric power generation, transmission, and

distribution.

OSHA is staying the enforcement of the following paragraphs of

Sec. 1910.269 until November 1, 1994: (b)(1)(ii), (d) except for

(d)(2)(i) and (d)(2)(iii), (e)(2), (e)(3), (j)(2)(iii), (l)(6)(iii),

(m), (n)(3), (n)(4)(ii), (n)(8), (o) except for (o)(2)(i), (r)(1)(vi),

(u)(1), (u)(4), (u)(5). OSHA is also staying the enforcement of

paragraphs (n)(6) and (n)(7) of Sec. 1910.269 until November 1, 1994,

but only insofar as they apply to lines and equipment operated at 600

volts or less. Further, OSHA is staying the enforcement of paragraph

(v)(11)(xii) of Sec. 1910.269 until Februrary 1, 1996.

III. Corrections.

Several provisions in Sec. 1910.269 contained minor typographical

or grammatical errors. Additionally, several national consensus

standards were approved and published by the American National

Standards Institute (ANSI) and by ASTM shortly after the promulgation

of revised Sec. 1910.137 and Sec. 1910.269. Some non-mandatory notes

and a non-mandatory appendix contained references to older editions of

these ASTM standards. These non-mandatory references are intended to

provide employers, employees, and other affected parties with

additional information on techniques of complying with the OSHA rules.

In fact, two notes in Sec. 1910.137 accept compliance with specific

ASTM standards as being compliance with Sec. 1910.137. The Agency has

reviewed the new ANSI and ASTM standards and has found them to provide

newer, more technically up-to-date information than the older versions.

Therefore, this correction notice is updating the references in

Sec. 1910.137 and Sec. 1910.269 to the later ANSI and ASTM standards.

In Sec. 1910.137, OSHA is retaining the slightly older editions of the

ASTM standards, in addition to the more recent editions, to clarify

that electrical protective equipment manufactured in accordance with

the older standards is still acceptable.
