Recorded in November 2020, this course describes the health/safety hazards associated with welding and thermal cutting processes. Welding fume has recently been categorized as a Group 1 Carcinogen. Welding is nearly ubiquitous in all industrial environments. 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.
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".
