MSA, the worldwide leader in worker protection and safety product innovation, was created in response to a mining explosion in 1912. With the help of Thomas Edison, John T. Ryan Sr. and George H. Deike create the electric cap lamp, which reduced mining explosions by 75 percent. MSA has 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, ballistic helmets, and leading edge systems for gas and flame detection. The company offers products that include fall equipment protection, eye and face protection, head and hearing protection, thermal imaging cameras, permanent gas and flame detection, portable gas detection, CBRNE detectors, air-purifying respirators, and supplied air respirators.
