About MSA Safety

Since its founding in 1914, MSA Safety has been at the forefront of personal protective equipment (PPE), engineering solutions specifically designed to keep workers safe in some of the world's most hazardous environments. Originally established as Mine Safety Appliances, the company has grown from its Pittsburgh, Pennsylvania roots into a global leader with operations spanning more than 140 countries and over 40 international locations.

For more than a century, MSA has built its reputation on a simple but powerful principle: the right safety equipment saves lives. From underground mines and construction sites to oil refineries and industrial facilities, MSA products are trusted by safety professionals worldwide. That trust has been earned through relentless innovation, rigorous testing standards, and an unwavering commitment to quality.

MSA's Core Product Lines

MSA's catalog is broad, but its expertise runs deepest in respiratory protection and head protection — two of the most critical categories in workplace safety. The company's respirators are among the most recognized in the industry, engineered to protect workers from airborne hazards including particulates, gases, and vapors. Whether on a construction site or inside an industrial plant, MSA respirators deliver reliable filtration performance backed by decades of research and development.

Complementing their respiratory lineup, MSA also offers complete respirator assemblies — ready-to-use configurations that pair facepieces with the appropriate filters and components for specific hazard environments. For workers who need lens protection in addition to respiratory coverage, MSA's respirator peel-off lens covers provide a practical solution, allowing quick lens replacement without interrupting workflow in the field.

Head protection is equally central to the MSA brand. Their line of hard hats reflects the same engineering rigor applied to all MSA products — designed to meet or exceed ANSI/ISEA standards while offering comfort features that encourage consistent, all-day wear. MSA hard hats are a familiar sight on job sites across North America and around the world.

For work at height, MSA's safety harnesses round out a comprehensive fall protection offering. These harnesses are built to distribute fall-arrest forces safely across the body, helping to minimize injury in the event of a fall — one of the leading causes of workplace fatalities in construction and industrial settings.
