A third Developmental design was also being developed by CRDL. The tubing should be attached somewhere else then the cap. More thought should be put into the design of the tubing and its attachment to the canteen. Most gas masks have sealing caps over the air intake and are stored in vacuum-sealed bags to prevent the filter from degrading due to exposure to humidity and pollutants in normal air. The use of the kit increases the breathing resistance for the wearer of the mask.[19]. Although the M17 series protective masks earned a reputation as being a reliable and robust mask that could stand up to difficult field environments, the series was vulnerable to faults unique to the design. May fit foreign varients. An example is synthetic resins. In 1984, Iran received gas masks from the Republic of Korea and East Germany, but the Korean masks were not suited for the faces of non-East Asian people, the filter lasted for only 15 minutes, and the 5,000 masks bought from East Germany proved to be not gas masks but spray-painting goggles. 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.

Note: These are military surplus filters and may be out of date. The filter elements came in white airtight, vacuum-packed paper/foil laminated bags with labels indicating the filter nomenclature. Filters are not returnable. to see larger image [38] It was made of plastic and rubber-like material that greatly reduced the weight and bulk compared to World War I gas masks, and fitted the user's face more snugly and comfortably. 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. The other unique feature of the mask was much less successful. They very quickly were adopted as a standard issue accessory to be used at all times on the ABC-M17 as a type of ballistic outsert to help protect the masks lenses from damage. The final mask designs that resulted from these experiments were two models based off of the third developmental model. Another model was also introduced at the same time called the E13R13. The carrier was always worn on the left side of the body in the hip, shoulder, or belt carrying configurations. The cap did not work with the older style canteens when introduced due to a threading mismatch but worked with all modern U.S. Army one-quart and two-quart canteens. 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. Most military gas masks are designed to be capable of protecting against all NBC agents, but they can have filter canisters proof against those agents (heavier) or only against riot control agents and smoke (lighter and often used for training purposes). 1st ed. Rubber degrades with time, so boxed unused "modern type" masks can be cracked and leak. Because of this, it was favored over the E13R12 which led to the E13R13s adoption as the M17A1 in 1966. WebThe gas mask filter that was used during WWII only lasted around eight hours. The U.S. doctrine at that time allowed for the use of chemical weapons in a retaliatory capacity (this was before the 1997 Chemical Warfare Convention)[25], however, coded diplomatic language made it clear that the use of chemical weapons by the Iraqis may trigger the use of nuclear weapons by the United States. WebGI M17 Gas Mask Filters - 1 Set. A disadvantage of this single-stage approach is that the aerosol can penetrate a significant distance into the composite aerosol/vapor filter material before being removed from the airstream leading to a shorter duration until the chemical agent breaks through the filter and enters the wearers respiratory system. It is a modification of the M17A1 mask and has no resuscitation tube. Same as the M10 but made of black rubber and featuring a rubber, five-point head harness. A common fault of the mask was the tearing of these buttonholes--often due to the frustration of the service member while trying to replace the filter elements. Around 1918, it was found that charcoals made from the shells and seeds of various fruits and nuts such as coconuts, chestnuts, horse-chestnuts, and peach stones performed much better than wood charcoal. The tubing size should be changed from a minimum 3/32 inch diameter to a inch minimum diameter. Screenshot from the 1995 movie Outbreak featuring troops in MOPP IV with the M17A2 mask leading an infected citizen to a quarantine facility. Another possible solution would be to store the tubing somewhere else then the canteen cap. 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. 95 ($89.95/Count) Save more with Subscribe & Save. Later designs incorporated a two-part strain relief system that had greater success at retaining the protective cover. 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 . Army Navy Sales offers genuine-issue military apparel from all major branches of the US Armed Forces, as well as camping and hiking gear, workwear, and military-themed gifts and vintage American heritage products. May fit other masks as well. The first consisted of a wire frame that fit into the perimeter of the eye lenses and suspended the corrective lenses roughly at eye level inside the mask. M17, M17A1 and M17A2 have shelf life? 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. The mask was designed to protect against respiratory gas attacks, biological attacks, and radioactive particles. The task of changing the filter elements could be made easier by lubricating the plastic lugs with water or more commonly, saliva before attempting to button the closure flaps.[13]. (this item provides ballistic protection also, to see details - follow image link), Insurance: It also should be noted that very early examples of inlet valve assemblies would have a little metal tab molded to the cap frame to help with easy removal of the caps. The bag was used in operations where the mask was likely to get wet; e.g. Although the voice diaphragm was a welcomed addition to American protective masks, it was minimally compatible with radio handsets of the era. However, in reality, the moisture content of the exhaled air condensed on the inside of the hood and eventually saturated the chemical protective overgarment rendering the garment less effective and increased the heat load on the wearer. The ABC-M17 was the standard-issue protective mask for the United States Army throughout the Vietnam war. Great gift for U.S. military small arms enthusiasts. Three kits were normally carried in a pouch inside the main compartment of the mask carrier along with the waterproof bag. This apparatus was made specifically for the M17A1 and attached over the exhale valve allowing a masked soldier to perform mouth-to-mouth resuscitation on an unmasked soldier. Chemicals in the paper cause-specific color changes when paper contacts liquid nerve or blister agents. In addition, moist sponges were inserted at the end of the hoses in order to better filter the air. M5C1) just on the top of the right or left side. As late as 1986, Iranian diplomats still travelled in Europe to buy active charcoal and models of filters to produce defensive gear domestically. May fit foreign varients. The markings on the rear of the elastic cloth headstrap. To decontaminate your skin, you would crush the glass ampules of the packet and fold the wipe to distribute the decontamination solution. With normal use, this process is slow enough not to affect the mask during its operational life, however, masks on the secondary market and "new-old-stock" eye lens outserts can show significant yellowing. In April 1988, Iran started domestic production of gas masks by the Iran Yasa factories. This was followed by the Black Veil Respirator, invented by John Scott Haldane, which was a cotton pad soaked in an absorbent solution which was secured over the mouth using black cotton veiling.[27]. This theoretically overpressurized the hood to make the infiltration of chemical warfare agent vapors less likely. There are two main difficulties with gas mask design: A primitive respirator was designed by Alexander von Humboldt in 1799 for underground mining, Various gas masks employed on the Western Front and Eastern Front during World War I, Finnish civilian gas mask from 1939. 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. (similar to the masks lens frames themselves) It was quickly redesigned soon after the introduction of the ABC-M17 to utilize a cheaper, more simplified crimped aluminum frame instead of one solid aluminum frame. 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. Filtration of air is only possible if there is sufficient oxygen in the first place. Price and availability subject to change without notice. WebAn M17-series chemical-biological mask , when properly fitted and worn with the hood, protects against field concentrations of all known chemical and biological agents in vapor or aerosol form. The filter elements were designated M13 and were improved over time to the M13A1 and M13A2. WebOnly WW1/WW2 gas masks actually contained asbestos, for GP-7 etc, only the filters contained asbestos. The filter elements for the M17 series mask are not compatible with the filter elements of the many foreign clones of the mask due to small differences in the size, shape and connecting mechanism. The M13 filter element pair used with the M17 protective mask is an exception to this orientation. It was used up till the 1980s. May fit foreign varients. Gas mask used by the French military. This experimental design was basically an M17 made entirely of grayish-green silicone rubber instead of the black butyl/natural rubber formulation of the basic M17 model.
