Due to possible contamination of the atmosphere of the submarine USS SALMON, SS-573, with Freon-TF during a cleaning operation of a motor generator at San Diego, a request was made by the Naval Ship Engineering Center for an NRL representative to provide on-the-spot analytical assistance and technical guidance. A commercially built Total Hydrocarbon Analyzer was used to monitor the atmosphere during and after the cleaning. The highest level of Freon-TF, 2. 5, was recorded in the bilge area during operation, indicating that liquid Freon had collected in this area. Using two blowers, approximately 80 hours of ventilation time was needed to get down to a Freon-TF concentration of 10 ppm in the affected compartments.
