OPINION

PER CURIAM:

Homelite, a Division of Deere & Company, petitions for review of
a final safety standard applicable to all logging operations promul-
gated by the Occupational Safety and Health Administration (OSHA)
pursuant to § 655(b) of the Occupational Safety and Health Act of
1970, 29 U.S.C.A. §§ 651-678 (West 1985 & Supp. 1995). Specifi-
cally, Homelite challenges OSHA's requirement that all chain saws
used by professional loggers be equipped with a chain brake. See 59
Fed. Reg. 51,672, 51,743 (1994) (to be codified at 29 C.F.R.
§ 1910.266(e)(2)(i)). Because we conclude that substantial evidence
supports OSHA's chain brake requirement, we deny the petition for
review.

I.

In terms of injury and fatality rates, logging is among the more
dangerous occupations in this country. See 59 Fed. Reg. 51,672,
51,673-80 (1994). Loggers face a wide variety of hazards arising from
their working conditions and the equipment that they use. In particu-
lar, gruesome injuries occur when an operating chain saw "kicks

                    2
back" and strikes a logger. "Rotational kickback" occurs when the
cutting chain near the upper portion of the tip of the guide bar (the
part of the saw that supports the chain and guides it into the wood)
contacts an obstruction, such as a nail or an untrimmed branch, caus-
ing the saw to move rapidly upward and backward toward the opera-
tor. "Pinch (or linear) kickback" occurs when the wood closes in on
the long edge of the cutting chain, pushing the saw toward the opera-
tor. While a chain saw can kick back in less than 0.3 of a second, the
average operator's reaction time is 0.75 of a second. Loggers often
cannot react quickly enough to avoid being struck by the chain saw.

Four safety devices have been developed to reduce or minimize the
risk of injury from chain-saw kickback. See 

tip
guards (or nose tip guards) are wedge-shaped devices bolted or
screwed onto the guide bar and shield the tip of the chain saw from
the types of obstructions that cause rotational kickback. Reduced-
kickback guide bars, which are narrower at the tip than regular guide
bars, reduce the likelihood of chain contact where kickback most
often occurs. Low- or reduced-kickback chains have idler or spacer
links between the cutting links of the chain that limit the force of
kickback. Chain brakes, located inside the engine of the chain saw,
are designed to stop the chain before the chain strikes the operator
when kickback occurs.

In 1985, a committee of the American National Standards Institute
(ANSI) set forth a voluntary industry standard for the manufacture of
chain saws. See Gasoline-Powered Chain Saws-- Safety Require-
ments, ANSI Standard B175.1 (1985) (ANSI B175.1). ANSI B175.1
requires manufacturers to equip chain saws with an engine size smal-
ler than 3.8 cubic inches of displacement with any two of the four
kickback safety devices. In addition, such saws must pass a perfor-
mance test involving the saw's computed kickback angle (CKA).
Chain saws with an engine size of 3.8 cubic inches of displacement
and larger, however, are required to have only one kickback safety
device and need not pass a CKA test. ANSI B175.1 also provides that
the average stopping time for a chain brake must not exceed 0.12 of
a second and no single stopping time may exceed 0.15 of a second.

On May 2, 1989, OSHA published a notice proposing an employee
safety standard for all types of logging operations that would replace

                    3
standards previously applicable only to pulpwood logging. See 54
Fed. Reg. 18,798 (1989) (to be codified at 29 C.F.R.§ 1910.266)
(proposed May 2, 1989). The proposed standard originally did not
require any particular safety device to prevent or reduce kickback
injuries; instead, it required frequent inspection of chain saws to
ensure "that chainbrakes and all other manufacturer's safety features
remain operational." 

May 11, 1990, OSHA pub-
lished notice of public hearings on the proposed standard and
requested comment on several issues, including "the adequacy of var-
ious chain saw safety devices and guards and the appropriate regula-
tory action for OSHA." 55 Fed. Reg. 19,745, 19,746 (1990). OSHA
conducted two public hearings on its proposed rule and received post-
hearing comments until November 21, 1990.

During the rulemaking proceedings, OSHA received comments and
heard testimony from individuals involved in the logging industry and
from representatives of logging safety organizations. Most com-
menters either reported that chain brakes had reduced kickback inju-
ries or predicted that chain brakes would reduce kickback injuries if
required. Many of these commenters also criticized the protective
value of the other safety devices, which were easily removed and
tended to interfere with cutting efficiency. The commenters favoring
chain brakes based their recommendations on general experience,
rather than empirical data. In addition to anecdotal commentary,
OSHA received statistics compiled by The State of Maine Bureau of
Labor Statistics (Maine BLS) in 1982, which indicated that chain
brakes had lessened the effects of kickback injuries. See 59 Fed. Reg.
at 51,691.

Some commenters, however, preferred that OSHA adopt the ANSI
standard that all chain saw manufacturers had been following because
a significantly different standard would disrupt the marketplace. See

disputed the effectiveness of chain brakes, but
OSHA determined that their contentions were unsupported by evi-
dence or data. See 

commenters, however, submitted
the 1982 Survey of Chain Brake Stopping Time in Eastern Canada by
the Forest Engineering Research Institute of Canada (FERIC). The
FERIC study indicated that only 25.2% of the saws tested stopped
within 0.15 of a second while 19.6% did not stop at all. Although the

                    4
commenter offered to provide OSHA with additional studies on chain
brake failure rates, OSHA never responded to his offer.

The administrative record also included Safe Chain Saw Design, a
book published in 1989 by the Institute of Public Safety (IPS).
Although not cited by OSHA in the final logging standard, IPS noted
that the Canadian Standards Association Committee on Chain Saws,
which had initiated the FERIC study, rejected the study's results and
continued to advocate chain brakes. IPS also supported the use of
chain brakes despite the FERIC study.

On October 12, 1994, OSHA promulgated its final logging stan-
dard, which requires that

          [e]ach chain saw placed into initial service after the effec-
          tive date of this section [February 9, 1995] shall be equipped
          with a chain brake and shall otherwise meet the require-
          ments of the ANSI B175.1-1991 "Safety Requirements for
          Gasoline-Powered Chain Saws."

be codified at 29 C.F.R.§ 1910.266(e)(2)(i)). Based
upon the comments it had received, OSHA concluded that chain
brakes should be required because: (1) chain brakes are effective and
the most widely used kickback safety device; (2) chain brakes have
widespread acceptance by logging professionals and are standard
equipment on almost all chain saws; (3) chain brakes lack the disad-
vantages of other safety devices; (4) other countries require chain
brakes; (5) the ANSI standard requires the use of sophisticated equip-
ment and exacting procedures to determine compliance; and (6) the
ANSI standard is primarily directed toward chain-saw manufacturers,
rather than employers and employees. See 

Portable Power Equipment Manufacturers Association
(PPEMA), a trade association representing chain saw manufacturers,
participated in the rulemaking proceedings and opposed the require-
ment of any specific kickback protection device. PPEMA and Home-
lite, one of its member companies, petitioned this Court for review of
the logging standard. Subsequently, PPEMA voluntarily withdrew its
petition.

Upon judicial review of a final standard promulgated by OSHA,
"determinations of the Secretary [of Labor] shall be conclusive if sup-
ported by substantial evidence in the record considered as a whole."
29 U.S.C.A. § 655(f). Substantial evidence is"such relevant evidence
as a reasonable mind might accept as adequate to support a conclu-
sion." American Textile Mfrs. Inst. v. Donovan, 

, 522
(1981) (internal quotation marks omitted). The substantial evidence
standard does not require OSHA to prove that the record supports
only one possible conclusion; indeed, "[t]he existence of a viable
alternative does not preclude the acceptance of an agency determina-
tion as supported by substantial evidence." Color Pigments Mfrs.
Ass'n v. OSHA, 

, 1160 (11th Cir. 1994); see also
Bedford County Memorial Hosp. v. Health & Human Servs., 

, 1021 (4th Cir. 1985) (stating that "an agency need not pick a
theoretical best solution for a problem, but rather, need only imple-
ment a reasonable solution"). Therefore, OSHA need only show that
its "determination is supported by evidence presented to or produced
by it and does not rest on faulty assumptions or factual foundations."

Homelite raises three challenges to OSHA's evidentiary support for
the logging standard. Homelite contends that OSHA: (1) lacked rele-
vant statistical data to support the chain brake requirement; (2) failed
to consider data indicating that chain brakes were ineffective; and (3)
lacked support for requiring both chain brakes and compliance with
ANSI B175.1. We reject these arguments and conclude that substan-
tial evidence supports OSHA's chain brake requirement.

Homelite first argues that OSHA could not have relied on its only
statistical data, the 1982 Maine BLS study, because it involved only
twenty-nine kickback injuries and reported the effects of the presence
of chain brakes in all chain-saw accidents, not accidents involving
kickback. Nonetheless, the study states that chain brakes "appear[ ] to
have played a significant role in lessening the effects of the injury.
Basically, the person injured in the kickback accident with the chain
brake was less likely to lose time or if the injury were disabling was
likely to lose fewer days." (J.A. 252.) Moreover, even if this Court
ignored the 1982 Maine BLS study, the numerous comments of chain

                     6
brake advocates based on their experiences constitute substantial evi-
dence supporting OSHA's determination that all chain saws should be
equipped with a chain brake.

Homelite's second contention, that OSHA refused to consider data
critical of the performance of chain brakes, is more troublesome.
Although some commenters disputed the effectiveness of chain
brakes, OSHA stated that none of them had submitted evidence or
data supporting their claims. See 

1982 FERIC study
submitted by one commenter, however, indicated that chain brakes
performed dismally under test conditions. OSHA now offers four
responses to the study: (1) the committee that initiated the study
rejected its results; (2) laboratory tests are less indica tive of effective-
ness than the favorable comments based on actual use in the forest;
(3) IPS recommended chain brakes despite the study; and (4) no certi-
fication program existed in Canada at the time of the study, rendering
it impossible to know how many tested saws had been manufactured
to stop the chain within 0.15 of a second.

Although OSHA probably should not have waited until this peti-
tion to defuse the results of the FERIC study, OSHA need not discuss
and defeat every comment contrary to the chosen standard, provided
its conclusion is supported by "such relevant evidence as a reasonable
mind might accept as adequate." American Textile Mfrs. 

. The majority of commenters, who based their recommen-
dations on years of experience, advocated chain brakes and criticized
the effectiveness of other safety devices. Thus, OSHA reasonably
could have discounted the single FERIC study, the results of which
were discredited by other materials in the administrative record.*

Finally, Homelite contends that OSHA lacked support for requiring
both chain brakes and compliance with ANSI B175.1, thereby estab-
lishing different safety standards for larger and smaller chain saws
_________________________________________________________________
*Homelite also argues that chain brakes are ineffective and impractical
because loggers cannot determine whether the chain brake is working
properly, i.e., whether it will stop the chain quickly enough to avoid an
injury. The factual basis for this concern, however, is contradicted in the
administrative record by the many commenters who reported fewer and
less serious kickback injuries when chain brakes were used.

                      7
used by loggers. Homelite asserts that it is illogical to require a more
stringent standard for smaller saws than larger saws and that OSHA
simply did not consider the full effect of incorporating ANSI B175.1
by reference. Some commenters, however, warned OSHA that adopt-
ing standards significantly different from ANSI B175.1 would disrupt
the marketplace because all chain saw manufacturers had been fol-
lowing the ANSI standard. See 

OSHA
reasonably could have determined that incorporating ANSI B175.1 by
reference would provide loggers with additional protection because it
establishes minimum performance criteria for chain brakes, as well as
other safety requirements.

Unpersuaded by Homelite's arguments, we conclude that OSHA's
determination that chain brakes should be required on all chain saws
satisfies the substantial evidence standard. Many representatives of
logging companies and safety organizations advocated chain brakes.
See 

on their experiences, these commenters
reported that chain brakes had been the most effective safety device
against kickback injuries. Although these commenters lacked statis-
tics to support their claims, OSHA reasonably could have relied on
the experiences of members of the industry affected by the standard,
especially if, as here, statistical data is sparse.

In addition to advocating chain brakes, many commenters pointed
out deficiencies in the other safety devices permitted by ANSI
B175.1. Many commenters noted that although bar or nose tip guards,
reduced kickback guide bars, and reduced kickback chains effectively
reduce the likelihood and severity of kickback injuries when used,
they are easily removed from chain saws. See 

thermore, these devices prevent certain logging maneuvers and tend
to reduce cutting efficiency, giving loggers incentives to remove or
replace them. Based on these comments, we conclude that OSHA rea-
sonably could have determined that chain brakes would be more
effective than the other devices because a logger would be less likely
to disengage or remove a safety device that did not interfere with the
chain saw's performance.

III.

Because the majority of commenters advocated chain brakes and
criticized other safety devices, we conclude that substantial evidence
supports OSHA's determination that chain brakes should be required

                    8
on all chain saws used by professional loggers. Accordingly, we deny
the petition for review.
