Government Approves E-Spectrum Technologies New Emergency Communication System for Use in U.S. Coal Mines
Ogden, UT · February 1, 2014 · Expanding on its popular line of industrial automation products, E-Spectrum Technologies
announced that the company's Rescue DogTM System has successfully completed the U.S. Department of Labor's Mine Safety and Health Administration
(MSHA) equipment safety certification process, the culmination of a two year application procedure that began on February 22, 2012.
This certification establishes Rescue Dog as one of only two systems worldwide to be approved by MSHA as a through-the-earth emergency communication
system for use in underground coal mines. Built on E-Spectrum's newly patented technologies that allow low power signals to travel wirelessly directly through
the earth for thousands of feet, the battery-powered Rescue Dog System will provide trapped or injured miners direct two-way communication with surface rescue personnel.
