This webinar describes common welding and thermal cutting processes associated with Manganese (Mn) exposures. Suggestions for improving the quality of monitoring data and prioritizing exposure assessments are provided. Ventilation techniques and respiratory protection options will also be described. Terminology used in the welding industry is incorporated throughout the webinar as a means of familiarizing participants with the vocabulary used in the workplace.

Learning Outcomes

Upon completion, participants will be able to:​​

  • Anticipate circumstances during welding and thermal cutting that can result in Mn overexposures.
  • Develop an exposure assessment strategy for welding and thermal cutting
  • Recognize and recommend effective ventilation/respiratory protection for control of welding fume.
