Mine Safety Appliances, or MSA, is a maker of sophisticated safety products that help protect workers who may be exposed to a variety of hazardous conditions. The company’s product line includes gas monitoring and detection instruments, filter-type respirators, gas masks, breathing apparatus used by firefighters, thermal imaging cameras, firefighter helmets, ballistic body armor, military communications systems, a broad range of industrial head and fall protection products, and safety products for Do-It-Yourself consumers. Key markets include construction, military, fire service, chemical production, oil and gas, and general industry.

MSA is based in the Pittsburgh suburb of O’Hara Township in Pennsylvania. With help from Thomas Edison, the company was formed in 1914 to develop a battery-powered cap lamp for miners to help prevent methane-related explosions caused by open flame lamps. Since the turn of the 21st Century, MSA has seen record sales. It should be noted that only a small portion of the company's current products involve mining related products. The corporation's assets are managed through two business segments: MSA North America and MSA International. MSA has sales and manufacturing operations throughout the world and sells products to customers in more than 140 countries. While the majority of MSA's products are available only through distributors, the company does sell head, eye, ear, respiratory and body protection products to individuals through a variety of hardware and home center retail outlets.
