Assessment of Exposure to Chemical Agents in Welding Fume

Published on

HSL Laboratories Research Report from 2000 (2000/15) which set out to re-evaluate the reliability of EH54 methods for assessing exposures to welding fume. The report concluded that while chemical composition of welding fume can be influenced by welding parameters, the variation was relatively small at <20%.  Voltage was the variable parameter which exerted the greatest…
