Magnesium oxide fume: Sources of emissions
Industry sources
In any industrial workplace where magnesium and magnesium compounds and alloys are used in "hot" operations such as welding, brazing, soldering, plating, cutting and metallising, magnesium oxide fumes may be formed due to the high temperatures reached in these operations. Examples include welding operations with magnesia in fluxes or the combustion of magnesium metal.
