MSHA approves MARCis unit

MineARC Systems has received Part 7 approval from the US Mine Safety and Health Administration (MSHA) for its MARCis intrinsically safe scrubbing and air conditioning system used in its CoalSAFE refuge alternatives.

The MARCis unit maintains the refuge chamber’s internal environment by continually removing the buildup of carbon dioxide, carbon monoxide and heat generated by the miners as they sit safely inside waiting for rescue.

According to the company, the MARCis unit is the first cooling system to be approved for coal mine refuge alternatives. Testing has shown that the refuge can operate in high temperatures, while still maintaining the 95°F internal apparent temperature threshold.

Commenting on the approval, MineARC Systems America general manager, James Rau, said: “Achieving MSHA approval is a significant step for MineARC. Customers can purchase from us with the confidence that our refuges meet the highest global safety standards in coal mining, relating to refuge alternatives.”
