ACNR Holdings, Inc.
Ohio County Mine, Mine I.D. No. 46-01436
Marshall County Mine, Mine I.D. No. 46-01437
Marion County Mine, Mine I.D. No. 46-01433
Harrison County Mine, Mine I.D. No. 46-01318 Docket No. M-2025-034-C
PROPOSED DECISION AND ORDER
On April 18, 2025, ACNR Holdings, Inc. filed a petition seeking modification of the application of 30 C.F.R. § 75.507-1(a) at its Ohio County Mine in Marshall County, WV, Marshall County Mine in Marshall County, WV, Marion County in Marion County, WV, and Harrison County Mine in Wetzel County, WV. The petitioner alleges that the alternative method in the petition will at all times guarantee no less than the same measure of protection afforded to the miners by the standard.
The petitioned standard, 30 C.F.R. § 75.507-1(a) – Permissible electric equipment states,
All electric equipment, other than power-connection points, used in return air outby the last open crosscut in any coal mine shall be permissible except as provided in paragraphs (b) and (c) of this section.
The petitioner is requesting a modification of the standard to allow the use of unapproved Powered Air Purifying Respirators (PAPRs) in return air outby the last open. Specifically, the petitioner is requesting to utilize the 3M Versaflo TR-800 Intrinsically Safe (Versaflo TR-800) PAPR motor/blower and battery with battery pack. The CleanSpace EX PAPR was granted in previous Proposed Decision and Orders, Docket Number M-2022-009–010-C and M-2023-008-C. Once this PDO becomes final, these Terms and Conditions will supersede the previous Terms and Conditions found in M-2022-009-010-C and M-2023-008-C.
The petitioner states that:
1. It currently uses the MSHA-approved 3M Airstream Headgear-Mounted (Airstream) PAPR System to protect miners working on its continuous miner sections. The Airstream provides a constant flow of filtered air to protect against potential exposure to respirable coal mine dust during normal mining conditions inby the last open crosscut. The Airstream is being discontinued by the manufacturer, no replacement components will be available, and there are no other MSHA-approved units.
2. The 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 certified by Underwriter Laboratories (UL) 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 Versaflo TR-800 is rated and marked “Ex ia I MA, Ex ia IIB T4 Ga, Ex ia IIIC 135oC Da; -20oC ≤ TA ≤ +55oC.”
3. The Versaflo TR-800 PAPRs provide a constant flow of air inside the headtop or helmet. This airflow provides respiratory protection and comfort in hot working conditions.
4. The Versaflo TR-800 is not MSHA-approved as permissible, and 3M is not currently pursuing MSHA approval.
5. The alternative method in the petition will at all times guarantee no less than the same measure of protection afforded to the miners by the mandatory standard.
The petitioner’s alternative method addresses training, inspections, examinations and records, servicing, continuous monitoring for methane and procedures when 1.0 percent or more methane is detected, battery chargers, battery charging and change out procedures, and special precautions for lithium batteries. These proposed terms and conditions for the use of Versaflo are consistent with those approved by MSHA for previous petitions, with one exception.
The petitioner did not include the following condition regarding treatment of lithium batteries approaching the end of their life cycle: “The battery must not be used at the end of its life cycle (i.e., when there is a performance decrease of greater than 20% in battery-operated equipment). The battery must be disposed of properly.” The electrolyte used in Lithium-ion batteries is volatile and can ignite under certain circumstances, including overcharging. MSHA requires inclusion of this additional condition to reduce the possibility of thermal runaway, and a subsequent fire or explosion caused by a battery self-igniting.
MSHA personnel investigated the merits of the petition and filed a report of their findings with the Administrator for Mine Safety and Health Enforcement. After a careful review of the entire record, including the petition and MSHA's investigative report, the Administrator issues this Proposed Decision and Order.

The petitioner alleges that the alternative method proposed in the submitted petition will, at all times, guarantee no less than the same measure of protection afforded by the standard.
Intrinsic Safety Description
Information regarding the UL listing for the Versaflo TR-800 and the CleanSpace EX PAPRs was previously submitted to the MSHA Approval and Certification Center (A&CC). A review was requested for the use of these unapproved PAPRs in areas of mines where permissibility is required. A&CC conducted the reviews and concluded that:
1. The Versaflo TR-800 PAPR is certified by UL according to the ANSI/UL 60079-11 standard. The UL certificate allows 3M to mark the device as “Ex ia I”, meaning that the unit is certified to be used in hazardous locations (“Ex”), has met the most onerous level of intrinsic safety protection (“ia”), and the Equipment Protection Level (“very high”) is acceptable for use in mines susceptible to firedamp (“I”). Due to legal and regulatory constraints, the UL certificate alone is not sufficient approval.
2. The CleanSpace EX is certified by TestSafe Australia (TSA) according to the International Electrotechnical Commission (IEC) 60079-0:2011 (General Requirements) and IEC 60079-11:2011 (Intrinsic Safety) standards. The certificate 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 U.S. mines.
Like the Versaflo TR-800, the CleanSpace EX is certified to be used in hazardous locations, meets the most onerous level of intrinsic safety protection, is acceptable for use in mining locations, the Equipment Protection Level is "very high", appropriate for use in mines susceptible to firedamp. In addition, its security is sufficient 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”).
NIOSH researchers, in a paper titled “An Evaluation of the Relative Safety of U.S. Mining Explosion-Protected 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 to MSHA criteria.
The UL certifications, TSA certifications, and 3M and PAFtec listing materials (drawings, certificate and text report) were found to support the conclusion that both the Versaflo TR-800 and the CleanSpace EX meet the ANSI/UL standard’s “two fault” intrinsic safety requirements for mining equipment.
The Versaflo TR-800 carries an ingress protection rating of IP64. The CleanSpace EX carries an ingress protection rating of IP66. Both ratings exceed the minimum rating of IP54 required by the ANSI/UL and IEC standards for intrinsically safe mining equipment.
Electromagnetic Interference Investigation
Review of the submitted materials indicate that both units, as unintentional radiators, have been tested and found to meet Federal Communications Commission (FCC) Title 47, Code of Federal Regulations, Part 15 requirements for digital devices for use in typical industrial environments. This means that, under the test conditions and in industrial environments, they were found to not cause harmful interference. Nevertheless, MSHA investigators tested the equipment in the mines to determine if PAPR electrical components such as the pump motor or battery create interference when used in close proximity to other electrical equipment.
Conclusion
When operating or working near continuous mining machines equipped with PDS, the manufacturer recommends a minimum separation distance of six inches between PDS MWCs and other electronic equipment to sufficiently reduce or eliminate interference. (See Appendix 1 for example diagrams of proper PAPR and PDS positioning on the body.)
When the PDS manufacturer’s recommendations requiring a six-inch separation between the PDS MWCs and the PAPRs’ battery pack or motor/blower were followed, MSHA testing showed no apparent interference or performance issues between the PAPRs and the electrical equipment tested typically worn, carried, or used on the CMM Sections (as detailed in Table 1 above).
Miner training should incorporate the importance of adhering to the PDS manufacturer’s recommendations so there is no interference between the PDS and PAPRs.
Based on the investigation discussed above, MSHA determined that the Versaflo TR-800 can be safely used where permissible equipment is required inby the last open crosscut, if the operator follows all the manufacturer’s recommendations and adheres to the Terms and Conditions of the Proposed Decision and Order.
On the basis of the petition and MSHA’s investigation findings, and the foregoing reasons, ACNR Holdings, Inc. is granted a modification of the application of 30 C.F.R. § 75.1002(a) at its Marshall County Mine, Ohio County Mine, Harrison County Mine, and Marion County Mine
ORDER
Wherefore, pursuant to the authority delegated by the Secretary of Labor to the Administrator for Mine Safety and Health Enforcement and pursuant to Section 101(c) of the Federal Mine Safety and Health Act of 1977, 30 U.S.C. § 811(c), it is ordered that ACNR Holdings, Inc.’s Petition for Modification of the application of 30 C.F.R. § 75.1002(a) in the Marshall County Mine, Ohio County Mine, Harrison County Mine, and Marion County Mine is hereby:
GRANTED, for the operator, who may use the non-permissible Versaflo TR-800 Powered Air Purifying Respirator (PAPR) inby the last open crosscut until such time that MSHA-approved permissible PAPR devices are available, subject to the conditions of this Order:
Terms and Conditions
1. Affected mine employees must be trained in the proper use and maintenance of the PAPR(s) to be used at the mine, the Versaflo TR-800 and/or the CleanSpace EX, in accordance with established manufacturer guidelines. This training shall alert the affected employees that neither the Versaflo TR-800 nor the CleanSpace EX PAPR is approved under 30 C.F.R. Part 18 and therefore must be de-energized when 1.0 or more percent methane is detected. The training shall also include the proper method to de-energize these PAPRs. In addition to the manufacturer’s guidelines, MSHA requires that mine employees be trained to examine the units before use to determine if any damage to the units exists that would negatively impact intrinsic safety, or any of the stipulations in this petition
2. The PAPRs, battery packs, all associated wiring and connections must be examined by a qualified person before use to determine if there are any observable defects or damage to the units that would negatively impact intrinsic safety. If any defect or damage is found, the PAPR must be removed from service.
3. Each PAPR shall be assigned a unique identification number. The operator shall maintain a separate logbook for the Versaflo TR-800 and CleanSpace EX PAPRs. The logbooks shall be kept with the equipment or in a location with other mine record books and be made available to MSHA upon request. The equipment shall be examined at least weekly by a qualified person as defined in 30 C.F.R. § 75.512-1 and the examination results 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 Versaflo TR-800 PAPR, and the “blocked filter” alarm on the CleanSpace EX PAPR. PAPR examination entries may be expunged after one year.
4. In addition to the “blocked filter” alarm on the CleanSpace EX PAPR, these units have a visual green/red filter indicator that turns red when the filter needs to be replaced. The mine shall stock an adequate supply of new CleanSpace EX filters and pre-filters.
5. All Versaflo TR-800 and CleanSpace EX PAPRs to be used inby the last open crosscut shall be physically examined by a qualified person as defined in 30 C.F.R. § 75.151 prior to initial use. 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 Versaflo TR-800 PAPRs shall include:
a. Check the equipment for any physical damage and the integrity of the case;
b. Remove the battery and examine for corrosion;
c. Inspect the contact points to ensure a secure connection to the battery;
d. Reinsert the battery and power up and shut down to ensure proper connections;
e. Check the battery compartment cover or battery attachment to ensure that it is securely fastened; and
f. For equipment utilizing lithium type cells, ensure that lithium cells and/or packs are not damaged or swollen.
The CleanSpace EX PAPR does not have an accessible/removable battery. The internal battery and motor/blower assembly are both contained within the sealed “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.
The operator is to ensure that all 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.
6. The Versaflo TR-800 and CleanSpace EX PAPR units that will be used inby the last open crosscut shall not be put into service until MSHA has initially inspected the equipment and determined that it is compliant with all the terms and conditions of this Order.
7. Prior to energizing the Versaflo TR-800 or the CleanSpace EX PAPR inby the last open crosscut, methane tests must be made in accordance with 30 C.F.R. § 75.323(a).
8. All hand-held methane detectors shall be MSHA-approved and maintained in permissible and proper operating condition. All methane detectors must provide visual and audible warnings when methane is detected in concentrations at or above 1.0 percent.
9. A qualified person shall continuously monitor for methane immediately before and during the use of the Versaflo TR-800 or CleanSpace EX PAPR inby the last open crosscut.
10. Neither the 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 Versaflo TR-800 or CleanSpace EX PAPR is being used inby the last open crosscut, the equipment shall be de-energized immediately and the equipment withdrawn from the area.
11. In the Versaflo TR-800, use only 3M TR-830 Battery Pack (TR-800 Battery Pack), which meets lithium battery safety standard UL 1642 or IEC 62133. In the CleanSpace EX, use only the CleanSpace EX Power Unit, which meets the same UL or IEC lithium battery safety standards.
12. Before each shift when the Versaflo TR-800 or CleanSpace EX PAPR is to be used, all batteries and power units for the equipment must be charged sufficiently for the expected usage on that shift. If spare battery packs for the Versaflo TR-800 PAPR are provided, all battery “change outs” must occur in intake air outby the last open crosscut.
13. The following maintenance and use conditions shall apply to equipment containing lithium-type batteries:
a. Neither the TR-830 Battery Pack nor the CleanSpace EX Power Unit may be disassembled nor modified by anyone other than permitted by the manufacturer of the equipment.
