Ozone and oxides of nitrogengeneration possible at welding arc or well awayfrom arc.Inert shielding gases can cause asphyxiation inconfined welding spaces and unventilated areas.Same as aboveNormally low, if any symptoms indicate the need,check for gaseous fluorides and/or oxides ofnitrogenSee Health Hazard Data given in Table 5 forsymptoms.Same as aboveOther conditions which also influence the composition and quantity of the fume and gases to which employees may be exposed include:(1) coatings on the metal being welded (such as paint, plating, galvanizing)(2) the number of welders and volume of the work space(3) the quality and amount of ventilation(4) position of the welder=s head relative to the fume plume, and(5) presence of contamination in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning and degreasing).H-1072-6 Page 17 of 17
