Welding: A Case Study in Occupational Hygiene

Course Description:
This course describes common welding, cutting, and hot work processes and the health and safety hazards associated with them. Adapted from a popular professional development course, this self-paced online course incorporates videos, interactive scenarios, and practice questions throughout to help deepen learner understanding of these complex processes.

The course emphasizes vocabulary common to the welding industry to prepare participants for interacting with welders in the workplace. It also utilizes detailed overexposure scenarios to describe the steps an OEHS professional should take to limit worker exposure. Among the potential exposures discussed are Manganese, Hexavalent Chromium, and the potential carcinogenic effects of Iron. The presenter also provides many actionable suggestions for improving the quality of monitoring data and improving the effectiveness of ventilation and other control methods.
