gas mask [16] The forerunner to the modern gas mask was invented in 1847 by Lewis P. Haslett, a device that contained elements that allowed breathing through a nose and mouthpiece, inhalation of air through a bulb-shaped filter, and a vent to exhale air back into the atmosphere. This appears to have been made in 1987. Sponsored. No markings whatsoever. [13], The filter element pouches on the mask were closed with a series of plastic dumbbell-shaped buttons and buttonholes in the rubber of the face blank and nose cup assemblies. The Second Developmental Model that was presented by Westinghouse was a design that had a movable mouthpiece that could be moved in and out of the users mouth with a rotary-actuated torque lever. [18] U.S. patent #6,529[19] issued to Haslett, described the first "Inhaler or Lung Protector" that filtered dust from the air. Filters will fit US M17 gas masks. Microphone Adapter Assembly For M17A1 Masks, Green Laser Protection Eyelenses Outserts, M5 Series Protective Ointment/Atropine Kits, ABC-M13 Individual Decontamination And Re-Impregnation Kit. Nato 40mm Gas Mask Filter The M17 has appeared in some post-apocalyptic art and comics throughout the 1970s and 1980s. This "copper poisoning" of the rubber was easily prevented by making sure the black lacquer on the brass hardware was in good repair and scratches or worn spots were covered with fresh black lacquer. Since a significant number of ABC-M17s were issued in Vietnam and improperly stored over the years, it can be difficult to find pristine examples today. The 3 models and the canteen were studied by CRDL personnel and their comments on the design were: In answer to the first objection, the Second Developmental Model will incorporate a shutoff valve of a rotary style action. However, worn properly, it provides added alpha and beta dust inhalation protection, and soldiers should wear it in all known situations until the contamination is identified. This prevented the build-up of ice from the moisture-laden, exhaled air under the hood in freezing temperatures. These asbestos-free filters are perfect for your Soviet MP4, M10 or M10M gas mask. In April 1988, Iran started domestic production of gas masks by the Iran Yasa factories. The filter elements came in white airtight, vacuum-packed paper/foil laminated bags with labels indicating the filter nomenclature. For use in high illumination areas and were essentially sunglasses for the protective mask. Such lack of instructions can only increase the appreciation for today's included instruction manuals on a lot of filter packages. That lever became a source of maintenance problems due to service members over-torquing the lever and cracking the metal of the voice diaphragm and outlet valve assembly. For use at night or in low light conditions. Great gift for U.S. military small arms enthusiasts. A modern mask typically is constructed of an elastic polymer in various sizes. Standardized in March 1959 and seeing full scale production by 1961, the US Army issued service members the ABC-M17 protective masks for the first time. This was corrected at the unit level with a dot of white paint where the stamp should be. It is one of the closest copy, only the rubber colour is different, which is green. The modification to the suit being the removal of the built-in hood, which allowed the ABC-M6A2 Field Protective Mask Hood to be used. Caney Gas Well Fire 1906 The polycarbonate formulation of both the eye lenses and eye lens outserts were prone to yellow over time due to exposure to UV light, excessive heat and atmospheric pollutants such as ozone. M17A2 with CPOG Type Overgarment During a CS Chamber Mask Confidence Exercise. As newer models of the M17 were introduced, the old ABC-M17s migrated to law enforcement agencies where the advanced features of later models were not as important for simple crowd control with tear gases. [33], The first effective filtering activated charcoal gas mask in the world was invented in 1915 by Russian chemist Nikolay Zelinsky. The tubing connected to the canteen is too small in diameter to drink appropriately in a short time period. These offered the same amount of protection as the later M6A2 hoods though were found unsatisfactory due to the lack of vecro adjustments and the lack of a zipper for ventilation which lead to the development and introduction of the ABC-M6A2 Protective Mask Hood in around the mid 60s. Iraq was known to have a large inventory of chemical munitions and it was feared that they would be used in the effort to drive Iraqi forces from Kuwait. [29] Macpherson presented his idea to the British War Office Anti-Gas Department on May 10, 1915; prototypes were developed soon after. Price and availability subject to change without notice. As filters age the risk of inhaling dangerous fibres increases even if the mask and filter look pristine, as you have no idea how the filter has been handled before it has come to you. Examples of substrates include activated carbon, and zeolites. Canteen 1 QT with NBC M-1 Cap Hood Filter Element Set, Chemical-Biological Mask M13A2, NSN: 4240-00-165-5026, Contract: DAAA09-85-C-1276, Mine Safety Appliances Co, MSA p/n: 303924 Military personnel are especially prone to being exposed to a diverse range of toxic gases. [1] The M17A2 retained the exterior tilt (rotary) lever for the drinking tube. Another possible solution would be to store the tubing somewhere else then the canteen cap. FOR ABC-M17, M17A1, AND M17A2 Kansas Operations - Redbudinc Learn more. Skip to the beginning of the images gallery. The E13-series masks tested these various configurations. In this spirit, new design requirements were drawn up for a compact design that did not have external filter canisters or hose-connected filter elements. Thus the user only has protection for a limited time, and then they must either, This page was last edited on 26 April 2023, at 23:59. Condition: New old stock. Though tests found the E50 resuscitation system performed satisfactory in properly resuscitating gas casualties with the required pressures and that the wearer could still properly continue their mission afterwards. The main improvement was replacing the separate filter canister connected with a hose by an easily replaceable filter canister screwed on the side of the gas mask.

Even though they were quickly replaced, they still saw service in late Vietnam and were used for training purposes in the later half of the 1970s-80s. (early examples of inlet valve caps may have the stamp in yellow ink as opposed to white ink) This was to ensure the internal louvers of the assembly faced downward to shed water and presumably liquid chemical warfare agents away from the filter media. Later designs incorporated a two-part strain relief system that had greater success at retaining the protective cover. Even in the more accurate representations of the use of M17 series protective mask, the wearers are seen as harbingers of evil. This theoretically overpressurized the hood to make the infiltration of chemical warfare agent vapors less likely. It was unclear though how one would move the tube into the users mouth when the resuscitation tube was installed since the tube would block the shutoff valve from being operated. The final mask, adopted as the M17, was a slightly modified E13R9. The filter is selected according to the toxic compound. This was the standard Nuclear, Biological Chemical (NBC) hood for the M17 series protective mask. These three designs were: It was agreed that the First Developmental Model of the mask should be based off of the 3rd design proposal. This principle relies on substances harmful to humans being usually more reactive than air. Pittsburgh Post-Gazette, November 30, 1960, Cartridge (respirator) Classification and marking of cartridges, Chemical cartridge Detection of end of service life, Learn how and when to remove this template message, Cartridges and canisters of air-purifying respirators, "Porton Down report on the presence of asbestos in World War II respirator canisters", "Guide for selection and use of filtering devices", "OSHA Bulletin: General Respiratory Protection Guidance for Employers and Workers", "Headaches and the N95 face-mask amongst healthcare providers", "Adverse skin reactions to personal protective equipment against severe acute respiratory syndrome a descriptive study in Singapore", "Historical Fabrications on the Internet", "Macpherson Gas Hood . This design was also not considered satisfactory due to the fact the mouthpiece remained in the user's mouth at all times. SEE S&H DETAILS BELOW). As late as 1986, Iranian diplomats still travelled in Europe to buy active charcoal and models of filters to produce defensive gear domestically. A relatively unknown manufacturer that has been seen on a few ABC-M17s outlet valve covers. The first incorporated a probe that would be attached to a hose from a canteen and fitted into the mask to drink. It is hypothesized that these were made to illustrate the internal workings of the mask to decision makers and were not intended to be a production model. The final stage of the polycarbonate eye lens degradation is severe yellowing, crazing, and embrittlement of the lens material. Approximately 3.3 million M17A1 and M17A2 masks were produced between 1967 and 1986. Language links are at the top of the page across from the title. Gas mask This arrangement plagued all M17 designs and was only improved with the M40 series protective mask that has a voice diaphragm located specifically to interface with radio handsets. They had ended their contract by 1964 leaving MSA as the only remaining manufacturer of face blanks. Unopened, vacuum sealed set of military filters for the US M17 gas mask. Training compensates for this but untrained civilian users might end up being uninformed on proper use. The ABC-M13 Individual Decontamination and Re-Impregnation kit replaced the M5 series kits and was carried in the external pocket of the M17 Mask Carrier. m17 gas mask [37], The British Respirator, Anti-Gas (Light) was developed in 1943 by the British. The solution was to 3D print a adapter that would clamp to the M17s voice emitter assembly and would screw to the threads on the VOICECOMM-II. An unmatched pair would lead to premature exhaustion of one of the filter elements. Unused gas mask filters from World War II may not protect the wearer at all, and could be harmful if worn due to long-term changes in the chemical composition of the filter. M17 Gas Mask Filters M17 US soldiers wearing M17A2 masks, fitted with the M6A2 protective hood during the Gulf War. A third Developmental design was also being developed by CRDL. Set includes 2 filters. It does not protect against ammonia vapors or carbon monoxide. Field Management of Chemical Casualties Handbook (3rd Ed. 211 W. Myrtle Street [31] More elaborate sorbent compounds were added later to further iterations of his helmet (PH helmet), to defeat other respiratory poison gases used such as phosgene, diphosgene and chloropicrin. The M17A2 is shown above. $70.00. [7], A filter type that can protect against multiple hazards is notated with the European symbols concatenated with each other. (waterproofing kit would be carried in the carriers inside pocket later on) Early carriers also incorperated a strip of canvs webbing on the right side of the carrier that could be used alongside sidekeepers to belt carry the carrier. by the late 60s this accessory had been completely removed from standard issue. It has been theorized that this is due to the masks butyl/natural rubber formulation being originally designed for low temperature, arctic climates. The kit contains six foil-packaged decontamination towelettes/wipes in an olive-drab plastic case that fits in a pouch in the rear of the M-17 mask carrier. However, a well trained soldier could accomplish the task in as few as five minutes. M17-Series Chemical-Biological Mask - Information.

The cloth was to be taken out of its container after you moisten the inner surface of the masks lenses with your fingertips. The first development model that used a push-pull mechanism to operate the was preferred for its easy operation, but as stated, this design would often cause the seal of the mask to break on the pull part of the action. [26] An immediate response was cotton wool wrapped in muslin, issued to the troops by May 1. Postal Service Thus, when handling asphyxiants, or when ventilation is poor or the hazards are unknown, filtration is not possible and air must be supplied (with a SCBA system) from a pressurized bottle as in scuba diving. A variety of items, depending upon the mission, were issued with the mask and stored in the mask carrier such as a waterproof bag that would protect the mask's filters from water damage during immersion. This is NOT made for any Israeli or Russian gas mask. Though it was crude, the hypo helmet was a stopgap measure for British troops in the trenches that offered at least some protection during a gas attack. In fact, some M17A2 masks were M17A1 masks modified at depot level maintenance to remove the resuscitation tube however, a vast majority were purposely manufactured M17A2 masks. [1] Although the M17A2 was eventually phased out and replaced by the M40 series protective masks, the extra-small version of the M17A2 was retained and issued to servicemembers with particularly small faces that could not be properly fitted with an M40 series mask. Talking on a radio while masked meant juggling the handset between ear and voice diaphragm leading to confused and muffled communications. M17A1 with the yellow valve for the drinking tube. THE FILTERS ARE NOT RETURNABLE. M17, M17A1 and M17A2 have shelf life? If the filter elements become saturated with water, the breathing resistance would dramatically increase and the protective qualities of the filter elements would be compromised. Write your own review. The first gas masks mostly used circular lenses made of glass, mica or cellulose acetate to allow vision. Will fit most soviet copies of the USGI M17 gas masks. A few examples of this mask were made with clear silicone rubber. Any filter markings - Surrounding the screw threads in black ink: A.B.L MA.5684 C.C.56 41 On the side in black ink: 12 66 M Next to the air intake in stamped metal from the underside: Cf 51 Overall darkish brown, one crimp seal on the edge where the sides meet the face the connector threads stick out from 6 ridges on the air intake side. M17 May fit foreign varients. Note the green connector ring that indicates the version of the filters. M17 Gas Mask Filter Set Also included, Operator's Manual for the Mask, Extra set new m17 filters, Bag for making the mask waterproof,and even a full Decontamination kit. The protection will wear off over time. The ABC-M17 was used by civilian law enforcement agencies for crowd control operations when protection from tear gas was required. Two initial designs were looked into by CRDL. Curiously, the M17 series is not well represented in video games perhaps due to the mask being out of service when sophisticated first-person shooter games were being developed. The carrier was always worn on the left side of the body in the hip, shoulder, or belt carrying configurations. [14], The filter elements could only be changed in a clean environment from the inside of the mask. Background For example, if the target particles are positively charged, a negatively charged substrate may be used. M17 Gas Mask The biggest objection to this design was how time consuming the process was to fit the connector into the mask and that it would be near impossible to use during a combat scenario.
