Welding and Flame-Cutting Fluoropolymer-Lined Metals

8 Welding and Flame-Cutting Fluoropolymer-Lined Metals 

screens, molds, screws, mandrels, screen packs, and other components of processing equipment should be periodically cleaned up and polymer residues removed. The cleaning method includes a pyrolysis step which should be conducted under adequate ventilation. 

Welding arcs and torches are capable of massive destmction of fluoropolymers due to the exeessive heat that they generate. The plastic part should be removed before metal is cut or welded. Local exhaust ventilation should be provided whenever it is not possible to remove the polymer from the area to be welded or cut. 

Tobacco products should be banned from the work areas to prevent polymer fume fever. Street elothing should be stored separately from work clothing. Thorough washing after removal of work clothing will remove powder residues from the body.
