I. Background

A. Executive Summary

    In 1971, the Occupational Safety and Health Administration (OSHA) 
adopted the American National Standards Institute (ANSI) standard Z88.2 
1969, ``Practices for Respiratory Protection,'' as well as ANSI 
Standard K13.1 1969, ``Identification of Gas Mask Canisters'' as its 
standard for respiratory protection. In April of 1971, OSHA promulgated 
29 CFR 1926.103, the initial respiratory protection standard for the 
construction industry. On February 9, 1979, OSHA announced that 29 CFR 
1910.134 would be formally recognized as also being applicable to the 
construction industry (44 FR 8577). On November 15, 1994, OSHA issued a 
Notice of Proposed Rulemaking to revise 29 CFR 1910.134 (59 FR 58884). 
On January 8, 1998, OSHA issued a Final Rule in the Federal Register 
(63 FR 1152) revising 29 CFR 1910.134. The prior respirator standard 
was re-designated as 1910.139 and applied only to respiratory 
protection against M. tuberculosis (TB). On December 31, 2003, OSHA 
withdrew 1910.139 and made compliance with 1910.134 effective 
immediately (68 FR 75776). On August 24, 2006, OSHA published revisions 
to the 1910.134 Final Rule, to add definitions and requirements for 
Assigned Protection Factors (APFs) and Maximum Use Concentrations 
(MUCs) (71 FR 50122). The revisions also supersede the respirator 
selection provisions of existing substance-specific standards with 
these new APFs (except for the respirator selection provisions of the 
1,3-Butadiene Standard).
    The current OSHA Respiratory Protection Standard (29 CFR 1910.134) 
aims to protect workers from inhaling hazardous airborne contaminants 
(e.g., dusts, fogs, fumes, mists, gases, smokes, sprays, vapors) in the 
workplace by requiring employers to establish a comprehensive written 
respiratory protection program that includes procedures for respirator 
use, training, and fit testing. A key component of this program is 
medical evaluation, which determines whether employees are physically 
able to wear respirators safely. Before using a respirator, employees 
must be evaluated by a physician or other licensed health care 
professional (PLHCP), using the mandatory OSHA medical questionnaire or 
an equivalent method, to assess medical conditions that could interfere 
with respirator use, such as cardiovascular or pulmonary diseases. A 
medical evaluation helps ensure that any employee required to use a 
respirator can tolerate the physiological burden associated with 
respirator use which is crucial to ensure worker safety. Additionally, 
the standard mandates fit testing for tight-fitting facepiece 
respirators, training on proper use and maintenance, and ongoing 
monitoring of workplace conditions to ensure the selected respirators 
provide adequate protection. The program must be regularly evaluated 
for compliance and effectiveness, with records maintained for medical 
evaluations, fit testing, and training, to reduce the risk of 
respiratory-related occupational illnesses.
    OSHA is proposing an update to the Respiratory Protection Standard 
to amend the medical evaluation requirements specified in paragraph (e) 
where an employee is required to wear either a filtering facepiece 
respirator (FFR) or loose-fitting powered air-purifying respirator 
(PAPR) and seeks comment on all aspects of this proposal. Using a 
respirator may place a physiological burden on employees that varies 
with the type of respirator worn, the job and workplace conditions in

[[Page 28465]]

which the respirator is used, and the medical status of the employee. 
OSHA has preliminarily determined this burden differs based on the type 
of respirator worn and therefore proposes an amendment to the medical 
evaluation requirements of the standard for FFRs and loose-fitting 
PAPRs.

B. Health Literature Background

Introduction
    In this section, OSHA provides an overview of the agency's evidence 
to determine whether this proposed rule impacts material impairment of 
health. The Secretary's material impairment determinations must be made 
``on the basis of the best available evidence'' and must consider the 
``latest available scientific data in the field'' (29 U.S.C. 
655(b)(5)). This overview briefly acknowledges the original basis for 
the determination of a need for medical evaluations before using FFRs 
and loose fitting PAPRs as well as considers research published after 
the promulgation of that rule.
    OSHA concludes that the data available for health effects are 
lacking and insufficient to establish that medical evaluations 
meaningfully reduce material impairment caused by wearing an FFR or a 
loose fitting PAPR. Even though ``OSHA is not required to state with 
scientific certainty or precision the exact point at which each type of 
[harm] becomes a material impairment'' (AFL-CIO v. OSHA, 965 F.2d 962, 
975 (11th Cir. 1992)), the level of evidence in the following 
discussion is unconvincing as it pertains to the ability of medical 
evaluations to prevent material impairment induced by the wearing of 
FFRs or PAPRs. The Occupational Safety and Health Act (29 U.S.C. 651, 
et seq.) (``the Act'' or ``the OSH Act'') charges OSHA with addressing 
all forms of material impairment, not just death or serious physical 
harm (Id.). The agency acknowledges that respirators may negatively 
impact some workers' health due to extreme exertion while wearing one, 
impact on communication or ability to see, triggering mental health 
concerns (e.g., claustrophobia), and other impacts on their quality of 
life. However, medical evaluation before use of an FFR or loose fitting 
PAPR is not well evidenced to prevent these outcomes.
Original Basis of the Medical Questionnaire Requirement
    When OSHA developed the respiratory protection standard in the 
1990s, the use of medical evaluations to identify underlying conditions 
where respirator use could cause material impairment was a well-
accepted best practice. This process was ``derived from studies of Navy 
SCUBA (self-contained underwater breathing apparatus) or military users 
under conditions unlike most current use'' (Harber et al., 2025). For 
the proposed standard (``Respiratory Protection Standard; Proposed 
Rule, 59 FR 58884), OSHA gathered information and presented for comment 
several alternatives ranging from in-person medical evaluations by 
physicians, exempting workers who use respirators for less than five 
hours a week, or using medical questionnaires presented by a PLCHP as a 
screening tool before a medical evaluation would be required. From this 
robust stakeholder engagement process, OSHA concluded that medical 
questionnaires would be permitted as a screening tool to identify 
individuals for whom an in-person medical examination would then be 
required in the final rule (63 FR 1152-1300). The questionnaire was 
adapted from ANSI Z88.6-1984.
    In the 1998 final rule (63 FR 1210), OSHA determined that there 
existed ``the potential for adverse health effects resulting from 
respirator use, even for healthy employees using respirators designed 
for low breathing resistance and used for short durations.'' OSHA also 
found that ``respirator use would impose a substantial risk of material 
impairment to the health of employees who have preexisting respiratory 
and cardiovascular impairments.'' Based on the results of studies in 
the record as well as the comments received, OSHA determined ``the use 
of any respirator requires a prior medical evaluation to determine 
fitness.''
    OSHA now believes that the requirement for medical evaluations 
before the use of any type of respirator is too broad in practice; 
specifically with respect to the use of FFRs and loose fitting PAPRs. 
Even the 1998 final rule included two commenters who expressed that 
medical limitations on their workforce were fairly limited with 
Organization Resources Counselors, Inc (Ex. 54-424) noting that 2% of 
their workforce were limited based on claustrophobia, asthma, and heavy 
smoking and Boeing (Ex. 54-445) reporting that 1-2% of their workforce 
was limited due to not undergoing the evaluation or because of employee 
preference (63 FR 1213, 1219). While 2% of the workforce is a small yet 
significant number, it does not identify actual avoided adverse 
outcomes from wearing a respirator. While it may have been reasonable 
to avoid this increased risk at the time, the agency concludes that it 
is important to consider new evidence in the years since the rule was 
published.
Lack of Data Showing Material Impairment Avoided by Medical Evaluations
    i. Lack of large scale epidemiological studies.
    The use of medical evaluations in respiratory protection programs 
as a prospective measure to avoid adverse health outcomes remains a 
well-accepted best practice. However, the agency is not aware of any 
epidemiological studies that evaluate their efficacy for FFRs and loose 
fitting PAPRs.
    Many workers currently use FFRs and loose fitting PAPRs without 
medical evaluations. For instance, NIOSH found that in the immediate 
wake of the publishing of the 1998 Respiratory Protection Standard 
51.2% of an estimated 281,776 establishments may not have performed 
medical evaluations to determine fitness for wearing a respirator 
(Doney et al., 2005). A 2015 study (Brousseau et al., 2015) reported 
that 14% of hospital workers in Illinois and 23% in Minnesota did not 
receive a medical evaluation. Medical evaluations are likely far less 
prevalent in many industries with smaller and more dispersed 
workforces. For instance, workers in hog farms commonly wear 
respirators, predominantly N95s, when performing some tasks, but are 
generally not subject to the Respiratory Protection Standard and are 
likely not following it (Gibbs et al., 2020). The agency knows of no 
data related to these worker populations showing that the lack of 
medical evaluations is causing adverse health effects. OSHA requests 
comment on the extent to which medical evaluations are effective at 
preventing adverse health outcomes resulting from the use of FFRs and 
loose-fitting PAPRs.
    ii. Despite large increases in respirator usage after the emergence 
of COVID-19, no evidence has surfaced illustrating the need for medical 
evaluations for FFR and PAPR usage.
    FFR and PAPR usage increased immensely after the emergence of 
COVID-19. Workers across industries performing a wide variety of tasks 
were suddenly wearing these respirators, often for their entire shifts 
every work day. Despite this sudden increased and widespread usage of 
these respirators, often without a medical evaluation, the agency is 
not aware of any data identifying adverse outcomes from individuals 
with underlying medical conditions during the COVID-19 pandemic. OSHA 
requests comment on

[[Page 28466]]

the extent to which workers have worn FFRs and loose-fitting PAPRs 
without medical evaluations since the emergence of COVID-19 in 2020.
    With this lack of data about medical evaluation efficacy for FFRs 
and loose fitting PAPRs, it is difficult to reaffirm that medical 
evaluations are either necessary or appropriate for preventing adverse 
health outcomes.
    iii. Few workers are refused respirators.
    As noted earlier, the data reported in the final rule for 
Respiratory Protection (29 CFR 1910.134) found that 2% or fewer workers 
did not pass the medical evaluation. That proportion appears to be 
fairly consistent with more recent studies. A 1999 study (Pappas et 
al.) found that out of 5,569 workers who had a medical evaluation only 
1.3% had limitations placed upon their work and 0.2% were denied use. 
Pregnancy was the reason for denial and the researchers found that 
physical examination and spirometry added nothing to the analysis. A 
2017 study (Desai et al.) found that only 1.48% of 337 subjects who 
passed the medical questionnaire evaluation failed the spirometry test 
under the American Thoracic Society criteria. In a survey of 35 clinics 
or clinic groups, Harber et al. (2025) found that nearly all workers 
were approved without restrictions and it was considered very unusual 
to decline approval.
    In practice, few workers have their respirator use limited. 
Additionally, we currently have no ability to estimate, to the agency's 
knowledge, how many adverse events are being avoided by restricting the 
use of FFRs and PAPRs by workers. As such, it is difficult to ascertain 
whether there is material impairment in these scenarios if a worker who 
should be restricted is permitted to use a respirator. OSHA requests 
comment on how many adverse events are being avoided by restricting the 
use of FFRs and PAPRs by workers.
    iv. Workers are able to respond quickly when symptoms arise.
    In the apparently rare circumstance that a worker develops symptoms 
from wearing an FFR or loose-fitting PAPR, these scenarios are not 
Immediately Dangerous to Life or Health (IDLH) situations. This is so 
because FFRs and loose fitting PAPRs are not permitted to protect 
employees in IDLH environments. Therefore, the worker should be able to 
seek safety with an exposure well below expected thresholds for adverse 
health outcomes. This is in contrast to other respirators--(e.g., self-
contained breathing apparatus (SCBA)--) that would be required in more 
dangerous exposure environments.
    v. Available data on effects largely shows minimal impact on 
health.
    As noted in the original rule (63 FR 1152-1300), self-contained 
breathing apparatus (SCBA) respirators require a great deal of exertion 
given the weight of that apparatus. However, the body of literature 
does largely agree that any physiological effects from wearing much 
lighter FFRs and PAPRs are minimal during low to moderate exertion. In 
studies assessing cardiovascular parameters, FFRs and PAPRs did not 
significantly impact health in low to moderate exercise scenarios that 
would be typical of the vast majority of workplaces (Epstein et al., 
2020; Anil et al., 2023). Similarly, Rothstein et al. studied 42 
individuals who did not have a history of claustrophobia or metabolic 
disease and found that individuals who wore N-95 respirators displayed 
minor changes in respiratory and metabolic effects, but those 
``physiological parameters remained within normal ranges at rest and 
would not impact daily functioning'' (Rothstein et al., 2025). A 
limitation on these studies is that they are performed on populations 
that screen out unhealthy individuals (e.g., smokers, known 
cardiovascular issues), but one would surmise that changes in 
physiological parameters would be observable even in healthy 
individuals and this does not seem to be the case. It is reasonable to 
assume that work that requires high exertion could impact the health of 
a wearer, but that high exertion work likely self-selects for 
individuals who would be medically fit to wear an FFR or a PAPR.
    The 1998 final rule also noted some concern about non-physiological 
impacts, specifically noting claustrophobia. A more recent look into 
the evidence found that the notion of large numbers of workers 
experiencing claustrophobia is unfounded (Harber and Beckett, 2023). In 
a letter to the editor, McClellan (2020) found that full-shift work 
using an FFR could cause issues, such as psychological stresses, that 
result in the wearer feeling compelled to remove their respirator in 
potentially unsafe situations. While psychological stressors have been 
observed and can induce physiological impairment, the agency is unable 
to adequately qualify the degree to which this occurs in the affected 
workplaces. And, as noted above, if a worker wearing an FFR or loose 
fitting PAPR had to remove their respirator due to psychological 
distress, the worker would necessarily not be exposed to an IDLH 
atmosphere but would rather be able to seek safety with an exposure 
well below expected thresholds for adverse health outcomes.
Conclusion
    The agency preliminarily concludes that there is not sufficient 
evidence to conclude that wearing FFRs and loose fitting PAPRs without 
a prior medical evaluation can result in unavoidable adverse outcomes, 
and that the assumption that medical evaluation effectively detects 
risk for adverse effects from the occupational use of FFRs and loose 
fitting PAPRs is unproven.

II. Discussion

A. Pertinent Legal Authority

    The purpose of the OSH 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(b)). To 
achieve this goal Congress authorized the Secretary of Labor (``the 
Secretary'') to promulgate standards to protect workers, including the 
authority ``to set mandatory occupational safety and health standards 
applicable to businesses affecting interstate commerce'' (29 U.S.C. 
651(b)(3); see also 29 U.S.C. 654(a)(2) (requiring employers to comply 
with OSHA standards), 29 U.S.C. 655(a) (authorizing summary adoption of 
existing consensus and established federal standards within two years 
of the Act's enactment), 29 U.S.C. 655(b) (authorizing promulgation, 
modification or revocation of standards pursuant to notice and 
comment), and 29 U.S.C. 655(b)(7) (authorizing OSHA to include among a 
standard's requirements labeling, monitoring, medical testing, and 
other information-transmittal provisions)). An occupational safety and 
health standard is ``. . . a standard which requires conditions, or the 
adoption or use of one or more practices, means, methods, operations, 
or processes, reasonably necessary or appropriate to provide safe or 
healthful employment and places of employment'' (29 U.S.C. 652(8) 
(emphasis added)). A standard is reasonably necessary or appropriate 
within the meaning of section 652(8) if it substantially reduces or 
eliminates significant risk or prevents it from developing, and is 
economically and technologically feasible, cost effective, consistent 
with prior Agency action or supported by a reasoned justification for 
departing from prior Agency actions, and supported by substantial 
evidence. See Am. Textile Mfrs. Institute, Inc. v. Donovan, 452 U.S. 
490 (1981); 58 FR 16612.-16616. The Secretary may also issue 
regulations requiring employers to keep records regarding their 
activities relating to the Act, as well as records of work-related 
deaths, injuries, and illnesses (29 U.S.C. 657(c)(1)-(2)).
    As required by the OSH Act, OSHA originally determined that the 
respiratory protection standard would substantially reduce a 
significant risk of material harm when promulgating the standard. For 
the changes in this proposed rule, OSHA has not made a new finding of 
significant risk but is making changes that are reasonably related to 
the purpose of the respiratory protection standard as a whole. When, as 
here, OSHA has previously determined that its standard substantially 
reduces a significant risk, it is unnecessary for the agency to make 
additional findings on risk for every provision of that standard. See, 
e.g., Pub. Citizen Health Research Grp. v. Tyson, 796 F.2d 1479, 1502 
n.16 (D.C. Cir. 1986) (rejecting the argument that OSHA must ``find 
that each and every aspect of its standard eliminates a significant 
risk''). Rather, once OSHA makes a general significant risk finding in 
support of a standard, the next question is whether a particular 
requirement is reasonably related to the purpose of the standard as a 
whole. See Asbestos Info. Ass'n/N. Am. v. Reich, 117 F.3d 891, 894 (5th 
Cir. 1997); Forging Indus. Ass'n v. Sec'y of Labor, 773 F.2d 1436, 1447 
(4th Cir. 1985); United Steelworkers of Am., AFL-CIO-CLC v. Marshall, 
647 F.2d 1189, 1237-38 (D.C. Cir. 1980) (``Lead I'').
    The Act also provides that in promulgating standards dealing with 
toxic materials or harmful physical agents, OSHA must set the standard 
that ``most adequately assures, to the extent feasible, on the basis of 
the best available evidence, that no employee will suffer material 
impairment of health or functional capacity even if such employee has 
regular exposure to the hazard dealt with by such standard for the 
period of his working life'' (29 U.S.C. 655(b)(5)). As discussed in 
Section IB, Health Literature Background, OSHA concludes that the data 
available for health effects are lacking and insufficient to establish 
that medical evaluations effectively prevent material impairment caused 
by wearing an FFR or a loose fitting PAPR.
    A standard is technologically feasible if the protective measures 
it requires already exist, can be brought into existence with available 
technology, or can be created with technology that is reasonably 
expected to be developed (see Am. Iron and Steel Inst. v. OSHA, 939 
F.2d 975, 980 (D.C. Cir. 1991)). Courts have also interpreted 
technological feasibility to mean that a typical firm in each affected 
industry or application group will reasonably be able to implement the 
requirements of the standard in most operations most of the time (see, 
e.g., Pub. Citizen v. OSHA, 557 F.3d 165, 170-71 (3d Cir. 2009) (citing 
United Steelworkers of Am., 647 F.2d 1189, 1272).
    OSHA has determined that this proposed rule does not impose any new 
feasibility burdens on employers. All employers in compliance with the 
existing standard will also be in compliance with the proposed 
revisions. This proposed rule simply removes some requirements for the 
use of medical evaluations for loose-fitting PAPRs and FFRs. Therefore, 
OSHA has determined that the proposed changes to 29 CFR 1910.134 are 
technologically feasible.
    In determining economic feasibility, OSHA must consider the cost of 
compliance in an industry rather than on individual employers. In its 
economic analyses, OSHA ``must construct a reasonable estimate of 
compliance costs and demonstrate a reasonable likelihood that these 
costs will not threaten the existence or competitive structure of an 
industry, even if it does portend disaster for some marginal firms'' 
(Am. Iron and Steel Inst., 939 F.2d at 980, quoting United Steelworkers 
of Am., 647 F.2d at 1272). OSHA has determined that this proposed rule 
is economically feasible because this action is deregulatory and 
imposes no additional costs.
    The Administrative Procedures Act directs agencies to include in 
each rule adopted ``a concise general statement of [the rule's] basis 
and purpose'' (5 U.S.C. 553(c)); cf. 29 U.S.C. 655(e) (requiring the 
Secretary to publish a ``statement of reasons'' for any standard 
promulgated)). This notice satisfies this concise statement 
requirement.
Estimated Cost Savings From Eliminating Requirement for Medical 
Evaluation for Filtering Facepiece Respirators and Loose-Fitting PAPRs
    OSHA estimated the potential cost savings associated with removing 
the medical evaluation requirement for

[[Page 28468]]

certain classes of respirators from CFR 1910.134 (Respiratory 
Protection) and potential reductions in the number of employees 
receiving follow-up medical exams. This required estimating the number 
of employees that would no longer receive the medical questionnaire for 
the specific type of respirators used as well as the number of 
employees that would no longer receive follow-up medical exams. A 
general description of the approach used to develop these estimates is 
presented below.
Annual Medical Questionnaire Cost Savings
    To estimate the number of employees that would no longer receive a 
medical questionnaire, OSHA used data from the National Institute for 
Occupational Safety and Health (NIOSH) survey on Respirator Usage in 
Private Sector Firms for 2001 (NIOSH, 2003). This survey represents the 
most recent and complete dataset on respirator usage available at 
present. The dataset includes estimates of the number of employees 
using certain types of respirators by broad industry division. Based on 
the estimates of employees using certain types of respirators, OSHA 
calculated the percentage of all employees across industry groups that 
use these types of respirators, comparing these estimates to employment 
figures in the County Business Patterns (CBP) dataset for 2001. OSHA 
then applied these percentages to the number of employees across 
industry groups estimated in the CBP dataset for 2022, which represents 
the most recent CBP dataset available. The NIOSH survey included mining 
employees in its population sample. Because mining is not covered by 
OSHA, an adjustment was made to the total number of potentially 
affected employees by subtracting employees within the Mining, 
Quarrying, and Oil and Gas Extraction sector (NAICS 21) that are 
outside of the following industries:

1--Crude Petroleum Extraction (NAICS 211120)
2--Natural Gas Extraction (NAICS 211130)
3--Drilling Oil and Gas Wells (NAICS 213111)
4--Support Activities for Oil and Gas Operations (NAICS 213112)

    One final adjustment that OSHA made for this analysis is to account 
for the specific type of respirator that employees use. Only those 
employees using either a filtering facepiece respirator (FFR) or loose-
fitting powered air purifying respirator (PAPR) will no longer have to 
complete a medical questionnaire or receive a medical evaluation. 
According to the 2022 County Business Patterns survey, there were 
approximately 136 million employees in the private sector. The NIOSH 
respirator survey found that about 1.939 percent of employees wore 
filtering facepieces, indicating that, assuming the profile remained 
the same, approximately 2.6 million employees wear filtering facepieces 
currently. Another 0.098 percent reported using loose-fitting PAPRs, 
which accounts for an additional 133,266 workers. These groups together 
would total 2.038 percent of employees, or 2,733,069 employees in 
private industry who currently use either an FFR or loose-fitting PAPR 
in their work. The spreadsheet detailing these calculations is 
available in the rulemaking docket on regulations.gov (Docket No. OSHA-
2025-0006).
    Since the medical questionnaire is only required for new employees, 
OSHA estimates the number of questionnaires that are no longer required 
by multiplying the number of covered employees in non-mining private 
industry that use either an FFR or loose-fitting PAPR in the course of 
their work by the Bureau of Labor Statistics' (BLS') Job Openings and 
Labor Turnover Survey (JOLTS) annual total separations rate (43.9 
percent). This approach results in an estimated 1,199,817 
questionnaires that are no longer required annually.
    The medical questionnaire is estimated to take an employee 15 
minutes \1\ on average to complete, which means that this new rule 
saves approximately 299,954 hours of labor time.
---------------------------------------------------------------------------

    \1\ This estimate of workers' time was used most recently in 
OSHA's estimates of cost of a respirator program in the COVID ETS 
rulemaking. See Document ID OSHA-2020-0004-1031. Arguably, a 
complementary amount of time would be required by the a PLHCP to 
review the questionnaire, but this cost may overlap with that 
already included in the cost of the exam. For simplicity this 
element has been left out of the calculation and therefore may be an 
underestimate.
---------------------------------------------------------------------------

    OSHA estimates the cost savings of this proposed rule using BLS' 
Occupational Employment and Wage Statistics data. Specifically, OSHA 
pulled the cross-industry median hourly wage for all occupations 
($23.80) and calculated the loaded hourly wage to account for fringe 
benefits. According to BLS' Employer Costs for Employee Compensation 
(ECEC) data for December 2024, the fringe rate was 31.1 percent. OSHA 
also accounts for indirect expenses that cannot be tied to producing a 
specific product or service, called overhead costs. OSHA used an 
overhead rate of 17 percent of base wages (EPA, 2002; Rice, 2002). This 
17 percent rate is based on an estimate of overhead costs for safety 
and health professionals in large private organizations. A rate of 17 
percent of base wages is equivalent to 11.71 percent of the hourly wage 
rate with fringe applied. To calculate the fully loaded hourly labor 
cost, OSHA added the three components together: base wages + fringe 
benefits (31.1 percent of total compensation) + applicable overhead (17 
percent of base wages). OSHA estimates a fully loaded wage of $38.59. 
Multiplying this wage by the total number of labor hours saved 
(approximately 299,954) results in total annual cost savings of 
$11,575,237. The total cost savings over a 10-year time period would 
equal roughly $115.8 million. The present value of these cost savings 
using a 3 and 7 percent discount rate would equal $98.7 and $81.3 
million, respectively.
Annual Follow-Up Medical Exam Cost Savings
    OSHA has previously estimated that 23 percent of all questionnaire 
recipients receive follow-up medical exams under the requirements of 
this standard.\2\ OSHA estimates that, with the medical questionnaire 
no longer required, paralleling the earlier preamble discussion, only 
about 2 percent of the original questionnaire recipients would still 
receive follow-up medical exams (see Section I.B., Health Literature 
Background). These employees are expected to be referred for medical 
exams after undergoing training as required under paragraph (k) of the 
existing respiratory protection standard.
---------------------------------------------------------------------------

    \2\ See the Supporting Statement for the PRA Information 
Collection Request (ICR) for 29 CFR 1910.134, Document ID OSHA-2011-
0027-0020.
---------------------------------------------------------------------------

    Using these estimates, OSHA calculated cost savings associated with 
medical exams no longer performed. OSHA multiplied the difference in 
pre- and post-standard revision required exams outlined above (21 
percent) by the number of questionnaires estimated in Section 1 
(1,199,817), which yields 251,962 employees that would no longer 
receive follow-up medical exams. The follow-up medical exams are 
estimated to take one hour to complete.\3\ Therefore, a total of 
251,962 burden hours are avoided. Using a fully loaded worker wage of 
$38.59 (derived previously), the total annual labor-based cost savings 
associated with medical exams equals $9,723,199.
---------------------------------------------------------------------------

    \3\ Id.
---------------------------------------------------------------------------

    OSHA also estimated the cost savings associated with not 
administering the medical exam itself. Using price data

[[Page 28469]]

from the Centers for Medicare & Medicaid Services (CMS) (https://www.cms.gov/medicare/physician-fee-schedule/search), OSHA estimates 
that these follow-up medical exams cost $193.75 each.\4\ Multiplying 
this unit cost by the number of medical exams previously estimated 
(251,962), OSHA calculates an additional $48,817,566 in annual cost 
savings.
---------------------------------------------------------------------------

    \4\ This estimate uses the costs for an office visit (HCPCS 
99203), spirometry (94010), chest x-ray (71048), and EKG (93000).
---------------------------------------------------------------------------

    In total, OSHA estimates annual medical exam cost savings of 
$58,540,765.
Annual Recordkeeping Cost Savings
    This proposed regulatory revision also impacts the cost to maintain 
medical records and provide employees access to these records upon 
request. OSHA estimates that there are 1,199,817 medical questionnaires 
and 251,962 follow-up medical exams that will no longer be required and 
thus will also no longer have records maintained. OSHA has previously 
estimated that each medical record takes a secretary five minutes on 
average to record in their entity's recordkeeping system.\5\ Therefore, 
this recordkeeping task is estimated to take secretaries a total of 
120,982 hours annually. OSHA also has estimated that 10 percent of 
employees will request their medical records, with each request 
requiring five minutes of secretarial time to process and deliver 
medical records to the requesting employee, totaling 12,098 hours of 
total burden time.\6\
---------------------------------------------------------------------------

    \5\ See the Supporting Statement for the PRA Information 
Collection Request (ICR) for 29 CFR 1910.134, Document ID OSHA-2011-
0027-0020.
    \6\ Id.
---------------------------------------------------------------------------

    In aggregate, this regulatory revision is expected to save 133,080 
burden hours of annual recordkeeping activities. Using a fully loaded 
wage for secretaries (SOC 43-6010) (based on BLS' Occupational 
Employment and Wage Statistics) of $37.00 yields $4.9 million in annual 
cost savings, with a present value using both 3 and 7 percent discount 
rates equaling $42.0 and $34.6 million, respectively.
Questionnaire Cost Savings if Baseline Compliance Were To Increase
    As part of this regulatory revision, OSHA also accounts for 
employees that have not yet received medical questionnaires that should 
have in the absence of this regulatory revision. The resulting effects 
will be presented as though they occur in a concentrated period of 
time; however, there is uncertainty about whether the existing non-
compliance would ever be addressed, and even if so, the timing is even 
more hypothetical.
    OSHA calculated the number of employees that have not yet received 
medical questionnaires by first subtracting the number of Mining, 
Quarrying, and Oil and Gas Extraction sector employees using FFRs from 
the total projected number of employees using these respirators using 
the same methodology as outlined in Section 1 (2,599,807 employees). 
(Note that this does not include those employees wearing loose-fitting 
PAPRs (133,262).) Next, OSHA assumed that 30 percent of these employees 
started wearing respirators during the COVID-19 pandemic but were never 
properly evaluated during this period. As a result, OSHA estimates 
that, in the absence of this regulatory revision, there are 779,942 
employees that would still need to receive the medical questionnaire. 
Assuming the same 15 minutes of burden time per medical questionnaire 
used in Section 1, OSHA calculates total burden savings of 194,986 
hours of workers' time. OSHA multiplied this burden savings estimate by 
the fully loaded worker wage ($38.59; derived previously) to estimate 
cost savings of $7,524,491. Annualizing this savings over 10 years 
using 3 and 7 percent discount rates equals $882,100 and $1,071,318, 
respectively.
Medical Exam Cost Savings if Baseline Compliance Were To Increase
    OSHA assumes that 23 percent of the employees that have not 
received a medical questionnaire identified in Section 4 will also not 
receive follow-up medical exams and does not require a further 
adjustment from 23 percent to 2 percent as was done in Section 2. 
Therefore, OSHA estimates that 179,387 current employees will not 
receive a follow-up medical exam given this regulatory revision. Given 
an assumed one hour to complete these follow-up medical exams, OSHA 
estimates an additional 179,387 hours of burden time saved by this 
regulatory revision. Using a fully loaded worker wage of $38.59, the 
one-time labor-based cost savings associated with these medical exams 
equals $6,922,532. Again, using the CMS-based unit cost for medical 
exams ($193.75), cost savings from the medical exams themselves equals 
$34,756,170. Total one-time medical exam cost savings equal 
$41,678,702. Annualizing these savings over 10 years using 3 and 7 
percent discount rates equals $4,886,015 and $5,934,109, respectively.
Recordkeeping Cost Savings if Baseline Compliance Were To Increase
    OSHA also considers cost savings associated with the medical 
records for those employees who should have but who did not receive a 
medical questionnaire or follow-up exam under the existing standard, 
for whom medical records will not be recorded and maintained due to 
this proposed revision. OSHA estimates that a total of 959,329 medical 
records (779,942 medical questionnaires and 179,387 follow-up medical 
exams) will no longer be needed to comply with this standard. OSHA 
assumes each medical record would have taken five minutes to record in 
recordkeeping systems. OSHA also assumes that 10 percent of employees 
would have requested access to these medical records, taking an 
additional five minutes per records request. These recordkeeping tasks 
are estimated to take 87,936 burden hours in total. Using a secretary's 
fully loaded wage of $37.00, OSHA estimates one-time recordkeeping cost 
savings of $3,253,723. Using discount rates of 3 and 7 percent and a 
time period of ten years, annualized cost savings equal $381,436 and 
$463,257, respectively.
Total Cost Savings
    Table 1 shows the total annualized cost savings associated with 
regulatory revisions to this standard.

  concentrated period of time. However, there is substantial uncertainty about the accrual of these savings and, if such accrual occurs, about the
  timing.
Source: OSHA DSG Office of Regulatory Analysis.

    As indicated in Table 1, OSHA estimates the annualized cost savings 
would be approximately $81 million at a 3 percent discount rate, or $83 
million at a 7 percent discount rate. The agency further estimates that 
the present value of those savings over the next 10 years would be $693 
million at a 3 percent discount rate, or $704 million at a 7 percent 
discount rate. The agency has estimated these cost savings will be 
spread across 131,089 firms, of which 127,351 are considered ``small'' 
by the Small Business Administration.
Uncertainties and Request for Comment
    The agency recognizes there is uncertainty in several areas in this 
calculation. One is the estimate of current respirator usage, which 
relies heavily on as a baseline from NIOSH's 2001 respirator survey, 
adjusted for growth in employment.\7\ The agency has reasonable grounds 
for believing that the use of FFRs has likely increased in the interim, 
in part because of their common usage during the COVID-19 pandemic. If 
this is the case, the cost savings from this regulatory change could 
potentially be larger.
---------------------------------------------------------------------------

    \7\ In 2023, NIOSH was commissioned to develop and administer 
and updated respirator usage survey. That effort is still underway 
and the results are not available at this time.
---------------------------------------------------------------------------

    Another source of uncertainty is the percentage of potential 
respirator wearers who are referred for medical exams currently, based 
on their answers to the questionnaire. A long-standing assumption, used 
in the agency's Information Collection Requests, based on earlier 
information originally used in its 1998 rulemaking, indicated that 23 
percent of users of all respirator types would be referred for further 
medical evaluation based on the questionnaire. But given both the low 
rates of employees being placed on restrictions for respirator use, and 
the relatively modest physiological demands of the type of respirators 
in question, suggests the percentage may be much smaller for this 
subgroup of respirator wearers (i.e., those using FFRs and loose-
fitting PAPRs).
    A third potential factor of uncertainty is the assumption that all 
employees newly hired will need to receive a new medical assessment for 
their fitness to wear a respirator. This may have been a useful 
assumption initially for establishing the economic feasibility of the 
Respiratory Protection rule in 1998 and the agency believes that 
frequently employers will err on the side of caution. However, under 
some circumstances an employer may rely on the written medical 
evaluation from a prior employer's PLHCP if the work conditions and 
type and weight of the respirator remains the same (see Section IX.E of 
OSHA's Respiratory Protection Directive, CPL 02-00-158 (June 26, 2014), 
but OSHA lacks information on how often that might occur so cannot 
account for this possibility in these estimates.
    These various sources of uncertainty will offset each other to some 
degree, and there are no doubt other parts of this cost-savings 
calculation that could be modified based on new information. The agency 
welcomes comment on the various assumptions and data sources used for 
this calculation.

B. Additional Requirements

i. OMB Review Under the Paperwork Reduction Act of 1995
    The Paperwork Reduction Act of 1995 (``PRA'') defines ``collection 
of information'' to mean ``the obtaining, causing to be obtained, 
soliciting, or requiring the disclosure to third parties or the public, 
of facts or opinions by or for an agency, regardless of form or 
format'' (44 U.S.C. 3502(3)(A)). Under the PRA, a Federal agency cannot 
conduct or sponsor a collection of information unless it is approved by 
OMB under the PRA and the agency displays a currently valid OMB control 
number (44 U.S.C. 3507). Also, notwithstanding any other provisions of 
law, no person shall be subject to penalty for failing to comply with a 
collection of information if the collection of information does not 
display a currently valid OMB control number (44 U.S.C. 3512(a)(1)). 
The process for OMB approval is found in 5 CFR part 1320. This proposed 
rule would impose no new information collection requirements. Because 
the revisions would affect only minor changes to the existing 
information collections in 29 CFR 1910.134 (OMB Control Number 1218-
0099), OMB has waived the requirements of 5 CFR part 1320 pursuant to 5 
CFR 1320.18(d).
ii. State Plans
    Under section 18 of the OSH Act, 29 U.S.C. 651 et seq., Congress 
expressly provides that States may adopt, with Federal approval, a plan 
for the development and enforcement of occupational safety and health 
standards that are ``at least as effective'' as the Federal standards 
in providing safe and healthful employment and places of employment (29 
U.S.C. 667). OSHA refers to these OSHA-approved, State-administered 
occupational safety and health programs as ``State Plans.'' \1\
    When federal OSHA promulgates a new standard or a more stringent 
amendment to an existing standard, State Plans must either amend their 
standards to be identical to, or ``at least as effective as'' the new 
Federal standard or amendment, or show that an existing State Plan 
standard covering this issue is ``at least as effective'' as the new 
Federal standard or amendment (29 CFR 1953.5(a)). However, when OSHA 
promulgates a new standard or amendment that does not impose additional 
or more stringent requirements than an existing standard, State Plans 
do not have to amend their standards, although they may opt to do so. 
OSHA has preliminarily determined this proposed rule does not impose 
additional or more stringent requirements than the existing standard, 
and therefore State Plans are not required to amend their standards. 
OSHA seeks comment on this assessment of its proposal.

[[Page 28471]]

iii. Environmental Impacts/National Environmental Policy Act (NEPA)
    OSHA has reviewed the proposed rule according to the National 
Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321 et seq.), as 
amended by the Fiscal Responsibility Act of 2023 (Pub. L. 118-5, 321, 
137 Stat. 10), and the Department of Labor's NEPA procedures (29 CFR 
part 11). OSHA has preliminarily determined that this proposal would 
have no impact on the quality of the human environment.
iv. Other Statutory and Executive Order Considerations
    OSHA has examined this proposed rule and has determined that it is 
consistent with the policies and directives outlined in E.O. 14192, 
``Unleashing Prosperity Through Deregulation.'' This proposed rule is 
expected to be an Executive Order 14192 deregulatory action.
    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires 
preparation of an initial regulatory flexibility analysis (IRFA) and a 
final regulatory flexibility analysis (FRFA) for any rule that by law 
must be proposed for public comment, unless the agency certifies that 
the rule, if promulgated, will not have a significant economic impact 
on a substantial number of small entities. OSHA reviewed this proposed 
rule under the provisions of the Regulatory Flexibility Act. This rule 
would eliminate burdensome regulations. Therefore, OSHA certifies that 
the rescission would not have a ``significant economic impact on a 
substantial number of small entities,'' and that the preparation of an 
IRFA is not required. OSHA will transmit this certification and 
supporting statement of factual basis to the Chief Counsel for Advocacy 
of the Small Business Administration for review under 5 U.S.C. 605(b).
    Executive Order (E.O.) 12866, ``Regulatory Planning and Review,'' 
58 FR 51735 (Oct. 4, 1993), requires agencies, to the extent permitted 
by law, to (1) propose or adopt a regulation only upon a reasoned 
determination that its benefits justify its costs (recognizing that 
some benefits and costs are difficult to quantify); (2) tailor 
regulations to impose the least burden on society, consistent with 
obtaining regulatory objectives, taking into account, among other 
things, and to the extent practicable, the costs of cumulative 
regulations; (3) select, in choosing among alternative regulatory 
approaches, those approaches that maximize net benefits; (4) to the 
extent feasible, specify performance objectives, rather than specifying 
the behavior or manner of compliance that regulated entities must 
adopt; and (5) identify and assess available alternatives to direct 
regulation, including providing economic incentives to encourage the 
desired behavior, such as user fees or marketable permits, or providing 
information upon which choices can be made by the public.
    Section 6(a) of E.O. 12866 also requires agencies to submit 
``significant regulatory actions'' to OIRA for review. OIRA has 
determined that this proposed rule is a ``significant regulatory 
action'' under the criteria in section 3(f)(4) of E.O. 12866. 
Accordingly, this proposed rule was submitted to OIRA for review under 
E.O. 12866.\8\
---------------------------------------------------------------------------

    \8\ OIRA has determined that this proposed rule is not an 
economically significant regulatory action under section 3(f)(1) of 
E.O. 12866.
---------------------------------------------------------------------------

    OSHA has considered its obligations under the Unfunded Mandates 
Reform Act (UMRA) (2 U.S.C. 1501 et seq.), and the Executive Orders on 
Consultation and Coordination With Indian Tribal Governments (E.O. 
13175, 65 FR 67249 (Nov. 6, 2000)), Federalism (E.O. 13132, 64 FR 43255 
(Aug. 10, 1999)), and Protection of Children From Environmental Health 
Risks and Safety Risks (E.O. 13045, 62 FR 19885 (Apr. 23, 1997)). Given 
that this is a proposed deregulatory action that involves the removal 
of medical evaluation requirements for employees required to use PAPRs 
and FFRs, that OSHA does not foresee economic impacts of $100 million 
or more, and that the action does not constitute a policy that has 
federalism or tribal implications, OSHA has determined that no further 
agency action or analysis is required to comply with these statutes and

C. Summary and Explanation of the Proposed Rule

    In this NPRM, OSHA proposes to remove medical evaluation 
requirements for employees required to use filtering facepiece 
respirators (FFRs) or loose-fitting powered air-purifying respirators 
(PAPRs), as specified in paragraph (e). As defined in paragraph (b), a 
filtering facepiece respirator means a negative pressure particulate 
respirator with a filter as an integral part of the facepiece or with 
the entire facepiece composed of the filtering medium. Paragraph (b) 
also defines loose-fitting to mean a respiratory inlet covering that is 
designed to form a partial seal with the face and powered air-purifying 
respirator to mean an air-purifying respirator that uses a blower to 
force the ambient air through air-purifying elements to the inlet 
covering. OSHA proposes that the initial medical evaluation 
requirements would only be removed for FFRs and loose fitting PAPRs and 
the medical evaluation requirements for any other air-purifying or 
supplied-air respirator would not be impacted and still apply. All 
other required provisions under the Respiratory Protection Standard (29 
CFR 1910.134), including the hazard assessment; selection of 
respiratory protection equipment; fit testing; training and education; 
and maintenance and care continue to apply under this proposal. OSHA 
anticipates that this approach will allow employers to focus medical 
evaluations on employees for whom those evaluations are likely to be 
beneficial.
    Currently, paragraph (e)(1) requires the medical evaluation of 
employees required to wear a respirator and a determination that those 
employees are able to use the respirators selected by the employer. 
Medical evaluation of employees prior to respirator use avoids exposing 
employees to the physiological stresses associated with such use. In 
the 1998 final rule revising the Respiratory Protection Standard (63 FR 
1152), OSHA found that adverse health effects can result, in some 
cases, even from short duration use of respirators. Through extensive 
literature review, the agency previously concluded there is a potential 
for adverse health effects resulting from respirator use, even for 
healthy employees using respirators designed for low breathing 
resistance and used for short durations. As such, the agency determined 
that respirator use would impose a substantial risk of material 
impairment to the health of employees who have preexisting respiratory 
and cardiovascular impairments.
    The proposed revision to the standard, as noted above, provides an 
exception for employees who use FFRs or loose-fitting PAPRs from the 
requirement that employers must medically evaluate employees required 
to wear a respirator. OSHA believes these revisions are appropriate due 
to the lack of data illustrating material impairment from wearing FFRs 
and loose-fitting PAPRs and the lack of data demonstrating that medical 
evaluations effectively predict adverse outcomes for workers wearing 
FFRs and loose-fitting PAPRs, as discussed in the Health Literature 
Background (Section IB. of this preamble). This lack of data is 
combined with widespread usage of FFRs and loose fitting PAPRs, 
especially in the wake of the COVID-19 pandemic. Ultimately, the agency 
preliminarily concludes that a finding that medical evaluations prevent 
adverse outcomes

[[Page 28472]]

from the occupational use of FFRs and loose-fitting PAPRs is 
unwarranted. While the agency does not question the need for medical 
evaluations for other types of respirators, the literature does not 
support their efficacy when using FFRs and loose-fitting PAPRs in 
environments that are not immediately dangerous to life or health. As 
such, proposed paragraph (e)(1)(ii) exempts employees required to use 
FFRs or loose-fitting PAPRs from the requirements of paragraph (e). The 
agency seeks comments on all aspects of this proposed change, including 
the submission of information and data on the efficacy of medical 
evaluations preventing adverse health outcomes when using FFRs or 
loose-fitting PAPRs. OSHA also seeks comment on voluntary respirator 
use, specifically if there are any concerns with the voluntary use of 
FFRs and loose-fitting PAPRs and the actions of this NPRM.
    Paragraph(s) (e)(2) through (e)(7) would not be impacted by the 
proposed exemption in paragraph (e)(1) for FFRs and loose-fitting 
PAPRs. If medical evaluation is required under paragraph (e)(1), the 
employer must comply with all requirements of paragraph (e). OSHA seeks 
comment on whether paragraph (e)(7) should remain applicable to FFR and 
loose-fitting PAPR use and require the employer to provide medical 
evaluations whenever symptoms arise that may be related to this use as 
well as any information or data on the current frequency of medical 
reevaluations as required by paragraph (e)(7).
    OSHA recognizes that adopting these revisions will also result in 
the revision of the respiratory protection requirements in OSHA's 
construction and maritime industry standards, which apply the 
requirements in 29 CFR 1910.134 to construction and maritime work. (See 
29 CFR 1926.103 (construction); 29 CFR 1915.154, 29 CFR 1917.92, and 29 
CFR 1918.102 (maritime)). OSHA is in the process of appointing members 
to the Advisory Committee on Construction Safety and Health (ACCSH). 
The agency intends to present this proposed rule to ACCSH once that 
process is complete. The agency will put the Committee's 
recommendations on the OSHA website and in the docket for this proposed 
rule prior to the close of the comment period to allow the public to 
provide comments on those recommendations.
