Engineers will stare intently at the molten pool of a weld through their visor and often forget the effect of fumes generated by the process. Although it's a subject which has received greater focus when the HSE is visiting engineering premises. Scientific evidence has shown that exposure to welding fume, regardless of the source, can cause lung cancer. To protect workers health, appropriate risk control measures are required in the hierarchical order, starting with local exhaust ventilation. This includes 'AI Fresco' welders whose equipment outsizes the workshop. To help us understand the subject, Hugh McPhillips, President of the South West Branch of The Welding Institute explained the science behind fume generation.
