It was founded by Otto Bernz (May 21, 1856 – February 17, 1932) in 1876[1][2] in Newark, New Jersey as Otto Bernz Co..[2] The company manufactures handheld torches and accessories, especially gas burner torches using fuel cylinders containing butane, propane, MAPP gas, and oxygen for soldering, brazing, and welding.
Its products include torches, fuel cylinders, kits, solders and accessories, and utility lighters.
[5] Bernzomatic, now a Worthington entity, continues to manufacture handheld propane and propylene ("Map-pro") cylinders found at big-box and hardware stores.
Cylinders containing propane fuel were omitted from the recall but under review due to several injuries, including a fatality.
In some instances severe injuries, including a fatality, were noted due to explosions attributed to failure of a pressure relief valve.
