Health and safety in welding and allied processes. Equipment for capture and separation of welding fume - Determination of the minimum air volume flow rate of capture devices Ingestion-build-79769 BS EN 419241-1 provides commonly1 Scope This document specifies two methods for establishing the minimum air volume flow rate. One method is dedicated for use with captor hoods, nozzles and slot nozzles with a ratio of slot length to hose diameter of 8: 1 or less. The other method is dedicated for use with on gun extraction devices. These methods are not applicable to down draught tables.
