Protecting the Welder from Ozone – A Scientific Study

Protecting Welders Against Ozone

Protecting the Welder from Ozone – A Scientific Study

Ozone (O3) is an extremely toxic gas that is generated when ultraviolet radiation produced by the welding arc reacts with oxygen, which can cause serious health issues to unprotected welders. The main objective of this study was to understand the levels of ozone that an unprotected welder may be exposed to across a variety of common welding processes and whether a Welding Helmet with a Powered Air Purifying Respirator (PAPR) was an effective control in protecting the welder from exposure to ozone.
