Having appropriate Metalworking Ventilation Equipment is important in minimizing exposure to the toxic fumes and gases produced when welding, cutting, or grinding metal. The items that help to provide such protection include air cleaners, backdraft or filter walls, downdraft tables, dust collectors, extractor arms, fume extractors, fume/vent hoods, fume vacuums, and welding booths. Many of them are available as permanent fixtures or as portables and vary in sizes/capacities to protect the entire shop or just where metalworking is done.
