Welding fume has recently been categorized as a Group 1 Carcinogen. Welding is nearly ubiquitous in all industrial environments. This course describes the health/safety hazards associated with welding and thermal cutting processes. This PDC will present: a) terminology used in the welding industry; b) materials, thermal processes, and scenarios associated with overexposure potential; c) how to improve the quality of monitoring data; d) how to prioritize exposure assessments; e) ventilation techniques; f) respiratory protection options for welding and thermal cutting processes; and Comparison of the application of the mixtures formula, NIOSH’s 0.010 mg/m3 suggested OEL for carcinogens, and Occupational Exposure Control Banding. Emphasis is placed on manganese and hexavalent chromium exposures as well as many other H&S hazards. An Excel spreadsheet for tracking relevant data for developing welding SEGs is provided.

Value Added

Attendees will receive electronic copies of AIHA's "Field Guidelines for Temporary Ventilation of Confined Spaces with an Emphasis on Hotwork" and "Welding Health and Safety, A Field Guide for the OEHS Professional".

Outcomes

Upon completion, the participant will be able to:

  • Describe H&S hazards associated with welding and thermal cutting.
  • Develop an exposure assessment strategy for welding and thermal cutting schemes.
  • Recognize effective ventilation for confined space welding and thermal cutting.
  • Identify issues that should be addressed during welding and thermal cutting in confined spaces.
