| Popis: |
Carbon dioxide removal aboard US submarines is accomplished with a working fluid of 24%wt monoethanolamine (MEA) water solution. MEA concentrations considered dangerous to humans have been reduced over the years. The potential exposure of submariners to MEA has two sources: the constant background in the ship's atmosphere due to Scrubber operation and short term exposure to the technician while Scrubber maintenance is being performed. During maintenance, events can occur that may potentially cause high exposure to the technician. Submarines no longer have a direct measuring detector tube for MEA. Long term ambient MEA exposure data are being collected and show that background levels are below safety limits that have been set. Measurements of the local exposure to the Scrubber technician reported here show that normal maintenance does not expose the technician to levels at or above the short term limits. |
