Western formally communicated the product issue to Praxair on 7/12/19, who had been previously in contact with Western regarding this issue. Western plans to issue a formal communication to affected distributors in the near future. The firm has initiated corrective action in the field as of August 2019. The firm has implemented a new screening process at each fill plant to identify and isolate units that could potentially be rotated past the stop. Units which fail are isolated and returned to Western, which will inspect each failed unit, replace the failed component with the revised knob/plate, and return the refurbished unit to the fill plant. One customer specifically requested that, instead of the screening procedure above, all of its units in service be replaced with the revised design. Western fulfilled this request. On October 11, 2019, Western mailed a Medical Device Recall letter to its distributors to officially communicate the issue.
