Product Description

Federal regulations require the approval or certification of certain mining products for use in underground coal and gassy underground metal mines. Technical experts from MSHA’s A&CC evaluate and test equipment, instruments, and materials for compliance. Products evaluated and tested range from small electronic devices to large mining systems. Following successful product evaluation and testing, a license is issued authorizing a manufacturer to produce and distribute products for use in mines. The MSHA approval issued by the A&CC is internationally recognized.
