A distinction is made between breathable substances (up to 100 µm large) and alveoli penetrating, i.e. Respirable substances (up to 10 µm large). These particles may reach the alveoli and deposit there and are therefore particularly dangerous. 98.9 % of particles in welding fumes are even below 0.4 µm in size.
The composition of welding fumes is determined by the material to be welded and the welding process in use.
Carbon monoxide (can have an effect on fertility)
Ozone
Risk of suffocation
Injury to airways and lungs (incl. cancer risk)
Hydrogen chloride, phosgene
Hydrogen, cyanide, formalin, isocyanate
Suffocation, injury to airways and lungs (incl. cancer risk), allergic reaction, asthma
Chronic damages to the airways and lungs (incl. cancer risk) as well as the central nervous system, allergic reaction, metal vapour fever
