The mask offers protection from chemical and biological warfare agents, but does not function properly in places where oxygen content is low.[1] The mask is not meant to be used for firefighting and does not provide protection from radiation, however the filters will stop irradiated particles from entering the respiratory system of the wearer. It is recommended that users continue wearing it until the biological or chemical agent is identified and verified cleared from the area using standardized unmasking procedures.
Because modern 40 mm gas mask filters are specialized to deal with any number of hundreds of toxins and airborne contaminants-ranging from chemical to biological, radiological and even nuclear-all while fitting the same gas mask.
M50 Gas Mask Serial Number Location VERIFIED

Avon Protection's Cadillac facility houses a number of highly automated manufacturing processes, including those for the M50 mask's visor and its unique twin conformal filters, the spokeswoman noted.
Currently, all 3 groups are used as indicators but in different applications. Detection of coliforms is used as an indicator of sanitary quality of water or as a general indicator of sanitary condition in the food-processing environment. Fecal coliforms remain the standard indicator of choice for shellfish and shellfish harvest waters; and E. coli is used to indicate recent fecal contamination or unsanitary processing. Almost all the methods used to detect E. coli, total coliforms or fecal coliforms are enumeration methods that are based on lactose fermentation (4). The Most Probable Number (MPN) method is a statistical, multi-step assay consisting of presumptive, confirmed and completed phases. In the assay, serial dilutions of a sample are inoculated into broth media. Analysts score the number of gas positive (fermentation of lactose) tubes, from which the other 2 phases of the assay are performed, and then uses the combinations of positive results to consult a statistical table (Appendix 2), to estimate the number of organisms present. Typically only the first 2 phases are performed in coliform and fecal coliform analysis, while all 3 phases are done for E. coli. The 3-tube MPN test is used for testing most foods. Analysis of seawater using a multiple dilution series should not use less than 3 tubes per dilution (5 tubes are recommended); in certain instances a single dilution series using no less than 12 tubes may also be acceptable. (For additional details, see: FDA. National Shellfish Sanitation Program, Manual of Operations. 2009 Revision. DHHS/PHS/FDA, Washington DC). Likewise, analysis of bivalve molluscan shellfish should be performed using a multiple dilution MPN series whereby no fewer than 5- tubes per dilution should be used, see section IV. There is also a 10-tube MPN method that is used to test bottled water or samples that are not expected to be highly contaminated (3). Analysis of citrus juice for E. coli is performed as an absence/presence method, see section V.
Serial Numbers - For the fastest service, please provide your serial number to us when inquiring about parts for your Invacare scooter or power wheelchair. Your serial number is typically located on the frame of your scooter or power chair and will not be located on any electronic components. You may have to remove your batteries or shroud to locate your serial number.Your serial number will resemble one of the following numbers: 02A12345 or 02BM123456 where the first two characters designate the year the product was made and the third character designates the month it was manufactured (A=January, B=February, etc.).
