Posted By John J Does anybody carry out swab testing for bacteria on respirators or can you point to any guidance on the subject, Regards, John

Posted By John J Merv, The swab test we currently use is electronic and gives an instant count. We wash all respirators after single use and the test is done randomly to ascertain if their is any bacteria present. This weekends weather has probably contributed to levels being slightly raised but not of concern in relation to the targets we use. I'm trying to rationalise this and find if we are legally obliged to test for bacteria or if this is something we adopted as it may be a good idea. Clearly if its the latter we are doing non value added work and we should be stopping. John

Posted By Ian Blenkharn The 'instant' swabs are based on ATP detection and may show the degree of soiling, but will not distinguish between types of micro-organisms present. Since soiling is inevitable after contact with skin surfaces, such tests are of doubtful value, but equally, so are more formal micro-biological examinations. I could quote for such work but would caution that it is of no great value and would rather not do it. I guess you might find someone to do the work for you, but it would be bad science! Swabs would be of even less value if examined by anyone without considerable microbiological expertise. Keep the equipment clean and dry. Sanitise with a detergent or suitably disinfectant product recommended by the manufacturer to ensure no likely deterioration of materials and loss of seal etc. Rinse to remove residues and dry thoroughly.

Posted By John J Thanks Ali, it is above 80 and the manufacturers have approved the process. Even more reason we need to ditch the test. On investigation it looks like the test was introduced following a sales visit from the swab testing company. Like most things if you paint a good enough picture somebodys going to go for it, John
