Fumes generated by soldering A woman at a bench working in front of a filtration system. A fume extractor is a device used to filter aerosolized chemical byproducts of the soldering process. [1] These devices take many forms depending on the project size and application, from small ductwork to entire fume hoods. [2]
Industrial Extraction is the process by which harmful air contaminants are removed from the work place for the protection of employees and the environment. [1]In the UK, the Health and Safety Executive has implemented COSHH regulations to ensure all industrial workplaces protect the health of their employees via effective Local Exhaust Ventilation (LEV).

Animated sequence of how a bore evacuator works. A bore evacuator. A bore evacuator or fume extractor is a device which removes lingering gases and airborne residues from the barrel of an armored fighting vehicle's gun after firing, particularly in tanks and self-propelled guns.
Most weld purging is carried out on joints made by the TIG or GTAW arc welding process. [6] When the laser welding process is chosen, joints or welds being made on reactive materials will need to be carried out and in the case of electron beam welding, this is carried out in a vacuum, in which case purging takes place by complete evacuation of all gas.
Exposure to manganese welding fumes, for example, even at low levels (<0.2 mg/m 3), may lead to neurological problems or to damage to the lungs, liver, kidneys, or central nervous system. [71] Nano particles can become trapped in the alveolar macrophages of the lungs and induce pulmonary fibrosis. [72]
