SUPPLEMENTARY INFORMATION: Section 

101(c) of the Federal Mine Safety and 

Health Act of 1977 and title 30 of the 

Code of Federal Regulations (CFR), part 

44, govern the application, processing, 

and disposition of petitions for 

modification. 

I. Background 

Section 101(c) of the Federal Mine 

Safety and Health Act of 1977 (Mine 

Act) allows the mine operator or 

representative of miners to file a 

petition to modify the application of any 

mandatory safety standard to a coal or 

other mine if the Secretary of Labor 

determines that: 

1. An alternative method of achieving 

the result of such standard exists which 

will at all times guarantee no less than 

the same measure of protection afforded 

the miners of such mine by such 

standard; or 

2. The application of such standard to 

such mine will result in a diminution of 

safety to the miners in such mine. 

In addition, §§ 44.10 and 44.11 of 30 

CFR establish the requirements for filing 

petitions for modification. 

II. Petition for Modification 

Docket Number: M–2024–036–C. 

Petitioner: Buchanan Minerals, LLC, 

P.O. Drawer L, Oakwood VA 24631. 

Mine: Buchanan No.1 Mine, MSHA ID 

No. 44–04856, located in Buchanan 

County, Virginia. 

Regulation Affected: 30 CFR 

75.1002(a), Permissible electric 

equipment. 

Modification Request: The petitioner 

requests a modification of 30 CFR 

75.1002(a) to allow the use of an 

alternative method of respirable dust 

protection. Specifically, the petitioner is 

requesting to use a battery powered 

respirable protection unit called the 3M 

Versaflo TR–800 powered air-purifying 

respirator (PAPR) in addition to the 

CleanSpace EX PAPR within 150 feet of 

pillar workings and longwall faces. 

The petitioner states that: 

(a) The petitioner is requesting to 

utilize the 3M Versaflo TR–800 PAPR in 

addition to the utilization of the 

CleanSpace EX PAPR, which was 

approved through a previous Proposed 

Decision and Order (PDO) granted by 

MSHA (MSHA Docket Number M– 

2021–023–C). 

(b) The 3M Airstream helmet has been 

used in mines for over 40 years. 3M has 

recently faced component disruptions 

for the Airstream product. This has 

caused 3M to discontinue, globally, the 

Airstream on June 1, 2020. The ability 

to order an Airstream system and 

components ended in February 2020, 

and components were available through 

June 2020. Currently, there are not any 

available replacement PAPRs that meet 

the MSHA standard for permissibility. 

PAPRs provide a constant flow of 

filtered air, which offers respiratory 

protection and comfort in hot working 

environments. Operators that were 

using the Airstream, do not have an 

alternative to provide to this type of 

protection to its miners. 

(c) Buchanan Minerals, LLC, is 

seeking alternatives to the 3M Airstream 

helmet to provide miners with 

respirable protection against respirable 

coal mine and silica dust, a protection 

that can provide long-term health 

benefits. 

(d) Both the CleanSpace EX and 3M 

Versaflo TR–800 PAPRs provide a 

constant flow of filtered air inside the 

half-mask, full mask or helmet. The 

airflow provides respiratory protection 

and comfort in hot working conditions. 

Both PAPRs shall be equipped with the 

following: Particulate protection 

classified as 100 series under 42 CFR 

part 84; or Particulate protection 

classified as High Efficiency ‘‘HE’’ 

under 42 CFR part 84. 

(e) Buchanan Minerals LLC, 

Buchanan No.1. Mine is seeking to 

continue the use of the CleanSpace EX 

PAPR and applying to utilize the 3M 

Versaflo TR–800 PAPR within 150 feet 

of pillar workings and longwall faces. 

(f) CleanSpace EX. 

(1) The CleanSpace EX is certified by 

TestSafe Australia (TSA) according to 

the IEC 60079–0:2011 (General 

Requirements) and IEC 60079–11:2011 

(Intrinsic Safety) standards. The 

certificate, issued to PAFtec Australia 

Pty Ltd (‘‘PAFtec’’), allows PAFtec to 

mark the device as ‘‘Ex ib IIB T4 Gb’’ 

and ‘‘Ex ia I Ma.’’ Due to legal and 

regulatory constraints, the TSA 

certificate is not accepted by MSHA as 

evidence that the PAPR is approved for 

use in US mines. The IEC certification 

marking that applies to mining, Ex ia I 

Ma, is discussed below: 

(2) The CleanSpace EX is certified to 

be used in hazardous locations (‘‘Ex’’); 

meets the most onerous level of intrinsic 

safety protection (‘‘ia’’); the level of 

protection is acceptable for use in 

mining locations (‘‘I’’), and the 

Equipment Protection Level appropriate 

for mining equipment, that has a ‘‘very 

high’’ level of protection, with sufficient 

security that it is unlikely to become an 

ignition source in normal operation, 

during expected malfunctions or during 

rare malfunctions, even when left 

energized in the presence of an outbreak 

of gas (‘‘Ma’’). 

(3) NIOSH researchers, in a paper 

titled ‘‘An Evaluation of the Relative 

Safety of U.S. Mining ExplosionProtected Equipment Approval 

Requirements versus those of 

International Standards’’, have 

determined that equipment, which 

meets two-fault intrinsic safety as 

defined in the ANSI/UL 60079 standard, 

would provide at least an equivalent 

level of safety as that provided by 

equipment approved under MSHA 

criteria. 

(4) The UL certification, TSA 

certification, and PAFtec listing material 

(drawings, certificate and text report) 

were found to support the conclusion 

that the CleanSpace EX meet the 

applicable ‘‘two fault’’ intrinsic safety 

requirements for mining equipment, as 

found in the ANSI/UL standard. 

(5) The CleanSpace EX carries an 

ingress protection rating of IP66. This 

rating exceeds the minimum rating of 

IP54 required by the ANSI/UL and IEC 

standards for intrinsically safe mining 

equipment. 

(6) This product is not MSHAapproved, and the manufacturer is not 

pursuing approval. The standards for 

the approval of this respirator are an 

accepted alternative to MSHA’s 

standards and provide the same level of 

protection. 

(g) 3M Versaflo TR–800. 


ddrumheller on DSK120RN23PROD with NOTICES1
90064 Federal Register / Vol. 89, No. 220 / Thursday, November 14, 2024 / Notices 

(1) The 3M Versaflo TR–800 PAPR 

with motor/blower and battery qualifies 

as intrinsically safe, based on reports by 

the International Electrotechnical 

Commission Systems for Certification to 

Standards Relating to Equipment for 

Use in Explosive Atmospheres (IECEx). 

The blower is UL-certified with an 

intrinsically safe rating of Division 1: 

Class I, II, III; Division 1: Groups C, D, 

E, F, G; T4 under the current standard 

of UL 60079; ATEX-certified with a 

rating of ‘‘ia’’. The 3M Versaflo TR–800 

is rated and marked Ex ia I MA, Ex ia 

IIB T4 Ga, Ex ia IIIC 135oC Da; 

120 °C≤TA≤+55 °C. 

(2) The 3M Versaflo TR–800 carries an 

ingress protection rating of IP64. This 

rating exceeds the minimum rating of 

IP54 required by the ANSI/UL and IEC 

standards for intrinsically safe mining 

equipment. 

(3) This product is not MSHAapproved, and the manufacturer is not 

pursuing approval. The standards for 

the approval of this respirator are an 

accepted alternative to MSHA’s 

standards and provide the same level of 

protection. 

(h) The alternative method will 

guarantee no less than the same measure 

of protection afforded the miners under 

the mandatory standard. 

The petitioner proposes the following 

alternative method: 

(a) Affected mine employees shall be 

trained in the proper use and 

maintenance of the PAPR(s) to be used 

at the mine, the 3M Versaflo TR–800 

and/or the CleanSpace EX, in 

accordance with established 

manufacturer guidelines. This training 

shall alert the affected employee that 

neither the 3M Versaflo TR–800 nor the 

CleanSpace EX PAPR is approved under 

30 CFR part 18 and therefore shall be 

de-energized when 1.0 or more percent 

methane is detected. The training shall 

also include the proper method to deenergize these PAPRs. In addition to 

manufacturer guidelines, MSHA shall 

require that mine employees be trained 

to inspect the units before use to 

determine if there is any damage to the 

units that would negatively impact 

intrinsic safety as well as all 

stipulations in the PDO granted by 

MSHA. 

(b) The PAPRs, battery packs, and all 

associated wiring and connections shall 

be inspected before use to determine if 

there is any damage to the units that 

would negatively impact intrinsic 

safety. If any defects are found, the 

PAPR shall be removed from service. 

(c) The operator shall maintain a 

separate logbook for the 3M Versaflo 

TR–800 and CleanSpace EX PAPRs that 

shall be kept with the equipment, or in 

a location with other mine record books 

and shall be made available to MSHA 

upon request. The equipment shall be 

examined at least weekly by a qualified 

person as defined in 30 CFR 75.512–1 

and the examination results shall be 

recorded in the logbook. Since float coal 

dust is removed by the air filter prior to 

reaching the motor, the PAPR user shall 

conduct regular examinations of the 

filter and perform periodic testing for 

proper operation of the ‘‘high filter load 

alarm’’ on the 3M Versaflo TR–800 

PAPR, and the ‘‘blocked filter’’ alarm on 

the CleanSpace EX PAPR. Examination 

entries may be expunged after one year. 

(d) All 3M Versaflo TR–800 and 

CleanSpace EX PAPRs to be used within 

150 feet of pillar workings or longwall 

faces shall be physically examined prior 

to initial use and each unit shall be 

assigned a unique identification 

number. Each unit shall be examined by 

the person to operate the equipment 

prior to taking the equipment 

underground to ensure the equipment is 

used according to the original 

equipment manufacturer’s 

recommendations and maintained in a 

safe operating condition. The 

examinations for the 3M Versaflo TR– 

800 PAPRs shall include: 

(1) Check the equipment for any 

physical damage and the integrity of the 

case, 

(2) Remove the battery and inspect for 

corrosion, 

(3) Inspect the contact points to 

ensure a secure connection to the 

battery, 

(4) Reinsert the battery and power up 

and shut down to ensure proper 

connections, 

(5) Check the battery compartment 

cover or battery attachment to ensure 

that it is securely fastened, and 

(6) For equipment utilizing lithium 

type cells, ensure that lithium cells and/ 

or packs are not damaged or swelled in 

size. 

(e) All CleanSpace EX PAPRs to be 

used within 150 feet of pillar workings 

or longwall faces shall be physically 

examined prior to initial use and each 

unit shall be assigned a unique 

identification number. Each unit shall 

be examined by the person to operate 

the equipment prior to taking the 

equipment underground to ensure the 

equipment is used according to the 

original equipment manufacturer’s 

recommendations and maintained in a 

safe operating condition. The 

CleanSpace EX PAPR does not have an 

accessible/removable battery. The 

internal battery and motor/blower 

assembly are both contained within the 

‘‘power unit’’ assembly and the battery 

cannot be removed, reinserted or 

fastened. Therefore, examination of the 

CleanSpace EX PAPR should include 

any indications of physical damage. 

(f) The operator shall ensure that all 

3M Versaflo TR–800 and CleanSpace EX 

PAPR units are serviced according to 

the manufacturer’s recommendations. 

Dates of service shall be recorded in the 

equipment’s logbook and shall include 

a description of the work performed. 

(g) The 3M Versaflo TR–800 and 

CleanSpace EX PAPR units that will be 

used within 150 feet of pillar workings 

or longwall faces shall not be put into 

service until MSHA has initially 

inspected the equipment and 

determined that it is in compliance with 

all the terms and conditions of the PDO 

granted by MSHA. 

(h) Prior to energizing the 3M Versaflo 

TR–800 or the CleanSpace EX PAPR 

within 150 feet of pillar workings or 

longwall faces, methane tests shall be 

made in accordance with 30 CFR 

75.323(a). 

(i) All hand-held methane detectors 

shall be MSHA-approved and 

maintained in permissible and proper 

operating condition as defined by 30 

CFR 75.320. All methane detectors shall 

provide visual and audible warnings 

when methane is detected in 

concentrations at or above 1.0 percent. 

(j) A qualified person as defined in 30 

CFR 75.151 shall continuously monitor 

for methane immediately before and 

during the use of the 3M Versaflo TR– 

800 or CleanSpace EX PAPR within 150 

feet of pillar workings or longwall faces. 

(k) Neither the 3M Versaflo TR–800 

nor the CleanSpace EX PAPR shall be 

used if methane is detected in 

concentrations at or above 1.0 percent. 

When 1.0 percent or more methane is 

detected while the 3M Versaflo TR–800 

or CleanSpace EX PAPR is being used, 

the equipment shall be de-energized 

immediately and the equipment 

withdrawn outby the last open crosscut. 

(l) The operation and location of the 

3M Versaflo TR–800 and CleanSpace EX 

PAPRs during underground blasting 

operations shall be defined in 

accordance with 30 CFR 75.1312(e)(1) 

and 75.1313(b)(1) and individualized 

underground blasting permits approved 

by the District Manager. 

(m) Only the 3M TR–830 Battery Pack 

shall be used, which meets lithium 

battery safety standard UL 1642 or IEC 

62133, in the 3M Versaflo TR–800 

PAPR. Use only the CleanSpace EX 

Power Unit, which meets lithium 

battery safety standard UL 1642 or IEC 

62133, in the CleanSpace EX PAPR.
