MSA dedicates significant resources to research which allows the company to develop a keen understanding of the customer safety requirements for a diverse range of markets, including the fire service, law enforcement, construction, public utilities, mining, chemical, petroleum, HVAC, hazardous materials remediation, military and retail. MSA’s principal products, each designed to serve the needs of these target markets, include respiratory protective equipment, thermal imaging cameras, gas detection instruments, ballistic protection, as well as head, eye, face, hearing and fall protection products.

MSA was founded in 1914 by John T. Ryan and George H. Deike, two mining engineers who had firsthand knowledge of the terrible human loss that was occurring in underground coal mines. Their knowledge of the mining industry provided the foundation for the development of safety equipment to better protect underground miners. While the range of markets served by MSA has expanded greatly over the years, the founding philosophy of understanding customer safety needs and designing innovative safety equipment solutions remains unchanged.

MSA is headquartered in Pittsburgh, Pennsylvania, with operations employing 5,100 associates throughout the world. A publicly held company, MSA’s stock is traded on the New York Stock Exchange under the symbol MSA.
