Mine Safety Appliances Company

Gas detection, breathing protection, and head protection are critical in oil, gas, petrochemical, construction, mining, and fire service settings. Mine Safety Appliances Company, operating as MSA Safety in Canada, manufactures Safety-Equipment and Instruments for workers and facility infrastructure exposed to hazardous conditions.

Our core products include self-contained breathing apparatus, fixed gas and flame detection systems, and portable gas detection instruments. These systems are built for sites where atmosphere monitoring and emergency breathing protection are part of the operating plan.

MSA was established in 1914 and serves markets around the world. In Canada, our North York presence connects customers with safety products used across oil and gas facilities, construction sites, mines, and emergency response work.

We also manufacture industrial head protection, fire and rescue helmets, and fall protection devices. These product families fit jobs where impact, fall, flame, and respiratory risks must be managed before work begins.
