MSA Safety Inc was incorporated in Pennsylvania on June 14, 1914 as Mine Safety Appliances. The Company is engaged in the development, manufacture and supply of products that protect people's health and safety. The Company's safety products integrate a combination of electronics, mechanical systems and advanced materials to protect users against hazardous or life threatening situations. Its safety products are used by workers around the world in markets including the oil and gas, fire service, mining and construction industries, as well as the military. The Company's products include fixed gas and flame detection systems, breathing apparatus where self-contained breathing apparatus or SCBA is the principal product, portable gas detection instruments, head protection products and fall protection devices. The Company's fixed gas and flame detection instruments are used in oil, gas and petrochemical facilities and general industrial production facilities to detect the presence or absence of various gases in the air. Typical applications of these instruments include the detection of an oxygen deficiency in confined spaces or the presence of combustible or toxic gases. Its multi-point permanently installed gas detection systems are used to monitor for combustible and toxic gases and oxygen deficiency in virtually any application where continuous monitoring is required. Its systems are used for gas detection in petrochemical, pulp and paper, wastewater, refrigerant monitoring, and general industrial applications. The flame detectors and open-path infrared gas detectors are used for plant-wide monitoring of toxic gases and for detecting the presence of flames. These systems use infrared optics to detect potentially hazardous conditions across long distances, making them suitable for use in such applications as offshore oil rigs, storage vessels, refineries, pipelines and ventilation ducts. The SCBA are used by first responders, petrochemical plant workers and anyone entering an environment deemed immediately dangerous to life and health. SCBA are also used by first responders to protect against exposure to chemical, biological, radiological and nuclear agents, which are collectively referred to as CBRN. Its hand-held portable gas detection instruments are used by oil, gas and petrochemical workers; general industry workers; miners; and first responders to detect the presence or absence of various gases in the air and applications of these instruments include the detection of an oxygen deficiency in confined spaces or the presence of combustible or toxic gases. It also offers industrial head protection that includes the iconic V-Gard helmet brand, a bellwether product. The Company's fall protection equipment includes confined space equipment, harnesses, fall arrest equipment, lanyards and lifelines. Fall protection equipment is used by workers in the construction industry, oil, gas and petrochemical market, utilities industry and general industrial applications, and anyone working at height.
