Abstract |
The project aim was to detect and quantify the products evolved during the hot gas welding of common fluoropolymers, to attempt to identify the causative agents of polymer fume fever. Carbonyl fluoride and/or hydrogen fluoride were detected from certain fluoropolymers when these materials were heated to their maximum welding temperatures. Significant amounts of ultrafine particles were also detected from all of the fluoropolymers investigated when they were hot gas welded. The report concludes that fluoropolymers should be hot gas welded at the lowest possible temperature to reduce the potential for causing polymer fume fever in operators. If temperature control is not sufficient to prevent episodes of polymer fume fever, a good standard of local exhaust ventilation should also be employed. |
