MSA Safety

MSA Safety is a Pennsylvania manufacturer of worker safety equipment, founded in 1914 and based in Cranberry Township. The publicly traded company makes the gear that keeps construction and industrial workers alive: fall-protection harnesses, gas detection, hard hats and, increasingly, connected devices that sense a fall and alert a supervisor. MSA built fall-detection sensors and worker-monitoring connectivity into its V-GARD H1 harness platform, part of a broader push to turn PPE into data. With falls still the leading cause of construction deaths, MSA’s equipment sits at the center of jobsite safety programs across the United States and worldwide.

MSA Safety’s construction-market page highlights five specific product families for the trade: head protection, full-body harnesses, self-retracting lanyards, portable gas detection and air-purifying respirators. That is a narrower, trade-specific slice of a catalog that also spans firefighter helmets, thermal imaging cameras and fixed gas and flame detection systems for industrial sites.

The company’s broader product architecture breaks into several lines on its US site: Connected Safety, which includes a Connected Work platform and an MSA+ subscription service, Detection & Monitoring, Gas Measurement & Process Control, Firefighter Safety, Above the Neck Protection, Fall Protection and Respiratory Protection. Recent product additions include the ALTAIR io 6 multigas detector, a portable unit with an integrated pump and built-in cellular connectivity, and the MSA G1 SCBA XR Edition, which the company states is certified to the NFPA 1970 2025 standard.

MSA has been active on the acquisition front in 2026. On July 9 it announced the completed purchase of Autronica Fire and Security, described on its site as a provider of fire and gas detection and alarm systems. The company also reported second-quarter 2026 results on July 30 and elected Octavio Marquez to its board of directors on July 21.

The company’s origin story, as told on its own history page, traces to a 1912 mine explosion. More than 80 miners died when methane gas ignited at the Jed Mine in West Virginia, and mine engineer John T. Ryan Sr. responded by founding the company and working with Thomas Edison to develop an electric cap lamp that, over the following 25 years, reduced mine explosions by roughly 75 percent.

The company’s Cranberry Township campus covers roughly 320 acres combining office space, manufacturing and research and development labs, according to a company press release, and as of a 2020 announcement MSA employed approximately 1,250 people in the Western Pennsylvania region as part of a global workforce of roughly 5,000.
