Monthly AIHA St. Louis Professional Development
Thursday June 25th - 1130a

I hope everyone is doing well and adjusting to their new lifestyle with COVID-19.  It has made it interesting with the AIHA Chapter.  I miss getting together with everyone over lunch.  Hopefully in the near future we will be able to meet up again.  Going virtual had brought in some advantages.  We can now have speakers from anywhere. 

This month we have Jerome Spear with J.E. SPEAR Consulting, LP presenting.  Jerome will be presenting on:
A Retrospective Exposure Assessment Study of Welding in Confined Spaces

During the construction of an elevated water tank, a steel tank erection crew was in the process of attaching an overflow pipe along the interior wall of the access tube. At the time, the access tube, approximately five feet in diameter, was laying horizontally at ground level. Prior to the arrival of an OSHA inspector, the pipe was being fitted and tack welded in place. As a result of the OSHA inspection, OSHA cited the employer for alleged violations under 29 CFR 1926.353(b)(1), "either general mechanical or local exhaust ventilation shall be provided whenever welding, cutting, or heating is performed in a confined space." No flammables or explosives were involved with the work inside the access tube. The OSHA inspector did not conduct air monitoring or collect air samples inside the access tube to determine whether the atmosphere inside the access tube was hazardous. In this case study, does OSHA have the duty to prove that noncompliance creates a hazardous condition? Is the burden on the employer to prove that a hazardous condition was not created? Were employees exposed to a hazardous condition from this exposure scenario? The methodology and results of a retrospective exposure assessment for this confined space scenario will be described. OSHA's citation policy of applying 29 CFR 1926.353(b)(1) has been clarified.
