It was a horrific workplace tragedy that led to the creation of MSA, the worldwide leader in worker protection and safety product innovation. On the morning of March 26, 1912, the Jed Mine in West Virginia exploded. In a flash, methane gas ignited and more than 80 miners lost their lives. In the decades that have come and gone, MSA has continued to lead the charge for workplace safety. We’ve led the way with small first-aid kits and portable methane detectors, and harnessed new technologies to produce state-of-the-art thermal imaging cameras, safety glasses, ballistic helmets, and leading edge systems for gas and flame detection.
