Matrix Design Group, LLC: Matrix Carbon Monoxide Sensor Passes Advanced Performance Testing, Receives NRTL Listing …

By

NEWBURGH, Ind.–(BUSINESS WIRE)–Matrix Design Group, LLC (Matrix), a subsidiary of Alliance Resource
Partners, L.P. (NASDAQ: ARLP), announced today that the Matrix
WAMS-S1000 Permissible Wireless Carbon Monoxide (CO) Monitoring Sensor
has been listed by Intertek, a Nationally Recognized Testing Laboratory
(NRTL). With this listing, the WAMS-S1000 fully complies with 30 CFR
75.351 set forth by the Mine Safety and Health Administration (MSHA) and
is the only post-accident, performance-tested, and NRTL-Listed CO sensor
on the market today.

“This accomplishment demonstrates our leadership in
cutting edge development of safety technology for the mining industry.”

“We are proud to deliver the first and only CO sensor compliant with the
performance-testing standards set forth by MSHA,” said Aric Pryor,
President of Matrix. “This accomplishment demonstrates our leadership in
cutting edge development of safety technology for the mining industry.”

As part of the performance testing required by MSHA for new CO sensors,
the sensor must pass rigorous tests to prove accurate performance and
resistance to Radio Frequency Interference (RFI). CO sensors often
experience problems with RFI when used in close proximity to two-way
radios. Unlike other sensors, the S1000 was specifically designed for
resistance to RFI even in close proximity to two-way radios. The S1000’s
resistance to RFI was confirmed by performance testing, which
established that the sensor is fully compliant with 30 CFR 75.351 and
APOL 2207, with no MSHA blasting clearance requirement.

The WAMS S1000 Sensor previously received MSHA Intrinsic Safety (IS)
approval (no. 18-A090002-0), allowing the sensor to remain in continuous
operation post-accident or during fan outages.

“At Warrior, safety has always been a top priority. We currently have
approximately 110 Matrix S1000 wireless sensors underground,” said Eric
Anderson, General Manager of Warrior Coal, LLC, a subsidiary of ARLP.
“Installing, calibrating, and relocating these new wireless CO sensors
has saved our men significant time. We are excited to have a compliant
CO sensor that can accurately monitor air conditions underground after
the fan is shut off or during other mine emergencies that require the
power to be turned off.”

The S1000 CO sensor is part of Matrix’s Wireless Atmospheric Monitoring
System (WAMS), which integrates with Matrix’s Miner and Equipment
Tracking System (METS) to provide a single underground infrastructure
for atmospheric monitoring, communication, and tracking. Currently,
there are over 1,000 S1000 units being utilized in US coal mines. For
