(1) In confined spaces, welding or cutting involving fluxes, coverings, or other materials which contain fluorine compounds shall be done in accordance with R 325.52912. A

fluorine compound is a compound that contains fluorine as an element in chemical combination, not as a free gas.

(2) Maximum allowable concentration. The need for local exhaust ventilation or airline respirators for welding or cutting in other than confined spaces will depend upon the individual circumstances. However, protection is desirable for fixed-location production welding and for all production welding on stainless steels. Where air samples taken at the welding location indicate that fluorides liberated are below the maximum allowable concentration, such protection is not necessary.
