The M17A2 is shown above. From US-Army field jackets to Marine Corps boots, Navy pea coats, and US Air Force glasses, our GI apparel is made in the USA and as stylish as it is functional. The white "TOP" stamp was often worn away or mis-stamped on the inlet valve assembly. Although unsightly, the bloom does not indicate damage to the function of the mask. [34], Also in World War I, since dogs were frequently used on the front lines, a special type of gas mask was developed that dogs were trained to wear. The hood attaches to the M17 series mask and protects the wearer's head and neck from chemical agent vapors or liquid droplets, biting insects, and radioactive dust particles. The diaphragm and outlet valve assembly on this model are also completely made out of grey plastic as opposed to the rubber that covers the assembly on the M10 Model. The Rotary-Actuated model also had problems with the rotary lever being difficult to operate, though it was still preferred over the Push-Pull design. Approximately 3.3 million M17A1 and M17A2 masks were produced between 1967 and 1986. 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. Be sure to check out our kids department too for children's military clothing and accessories. 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. 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. [18] U.S. patent #6,529[19] issued to Haslett, described the first "Inhaler or Lung Protector" that filtered dust from the air. Gas mask used by the French military. US soldiers wearing M17A2 masks, fitted with the M6A2 protective hood during the Gulf War. [20] The hose assembly was difficult to use and often broke the seal on the wearer exposing the service member to chemical warfare agents.

It has been theorized that this is due to the masks butyl/natural rubber formulation being originally designed for low temperature, arctic climates. Glass and mica were quite brittle and needed frequent replacement. Because of this, D.T marked face blanks are the second rarest. [18] The cap had a protective cover attached with a strap of plastic, but the plastic was susceptible to fatigue and quickly broke, losing the protective cover and rendering the cap unserviceable. However, for agents that cause harm through contact or penetration of the skin, such as blister agent or nerve agent, a gas mask alone is not sufficient protection, and full protective clothing must be worn in addition to protect from contact with the atmosphere. It is fitted with various adjustable straps which may be tightened to secure a good fit. The M17 series protective mask took a slightly curved, triangular filter elements often referred to as "pork-chop-shaped." 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. Absorption is the process of being drawn into a (usually larger) body or substrate, and adsorption is the process of deposition upon a surface. However, if the mask is for a particular use (such as the protection from a specific toxic material in a factory), then the design can be much simpler and the cost lower. More About Us. [30] The design was adopted by the British Army and introduced as the British Smoke Hood in June 1915; Macpherson was appointed to the War Office Committee for Protection against Poisonous Gases. This was coupled with a tube that extended outside the mask with a quick disconnect assembly on the end to attach to a specially modified canteen with a hose extension so the wearer could drink from the hip. The UK HSE textbook recommends limiting the use of respirators without air supply (that is, not PAPR) to one hour.[14]. An M17-series chemical-biological mask (Figure 1-5), 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 kit also prevents frost accumulation on the inlet valve caps. Filters cease to provide protection when saturated with hazardous chemicals, and degrade over time even if sealed. [citation needed]. Specially outfitted Soldiers would then clear the tunnels of enemies and booby traps. 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. [7], A filter type that can protect against multiple hazards is notated with the European symbols concatenated with each other. The carrier was always worn on the left side of the body in the hip, shoulder, or belt carrying configurations. WebUS Army issue M17 series gas mask used with original issue carrying bag for mask & all accessories in Main photo included. With the proliferation of the G-series and relatively new V-series nerve agents, the US military decided to design a new mask to meet the challenges of these new threats. Note carrier in hip carrying configuration. Then have the tubing plugged into the canteen cap when the wearer wants to drink. Carey, C., 1998. The two masks that made it to the final testing phases were two masks, the E13R12 and E13R13.

Also, it had replaceable plastic lenses. The M1 (E50) resuscitation tube was incorporated with the mask that was designed to allow a masked soldier to provide artificial respiration to an unmasked casualty. [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. Soft wire was also used for ease of adjustment during testing and evaluation phases. [19] The waterproof bag contained a high concentration of plasticizers as part of its formulation to keep the bag soft and pliable in both hot and cold conditions and after long-term storage. 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. Likewise, the M13 series filter elements will not fit into any of the M17 series clones.[17]. by the late 60s this accessory had been completely removed from standard issue. 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.

Edgewood Chemical Biological Center 85th Anniversary Flyer, Field Manual 3-8, Chemical Reference Handbook, Page. [26] An immediate response was cotton wool wrapped in muslin, issued to the troops by May 1. [13], The filter elements were composed of lightweight gas-aerosol filter material that fit into cheek pouches of the mask. (only the upper pocket on late carriers) These pockets were to store accessories as well as the shoulder/waist and waist/leg straps. These outserts provide protection from ruby and neodymium type lasers. Even in the more accurate representations of the use of M17 series protective mask, the wearers are seen as harbingers of evil. Note the Chemical Corps insignia stenciled on the carrier. The particulate filtration stage is typically located upstream of the vapor filtration stage so that volatile material released by the trapped aerosol is removed by the vapor filter. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face.

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. Isoamyl acetate, a synthetic banana flavourant, and camphor are often used as innocuous challenge agents. Product Reviews. This condition may result in a compromised seal which rendered the mask unusable. Although thorough training and the availability of gas masks and other protective equipment can nullify the casualty-causing effects of an attack by chemical agents, troops who are forced to operate in full protective gear are less efficient in completing tasks, tire easily, and may be affected psychologically by the threat of attack by those weapons. WE MAKE NO CLAIMS AS TO THE EFFECTIVENESS OF ANY OF THE GAS MASKS FILTERS. Due of this short production run, Firestone face blanks are the rarest with only a year of production. Seeking to improve on the Black Veil respirator, Cluny MacPherson created a mask made of chemical-absorbing fabric which fitted over the entire head.

Attaching a shutoff valve to the resuscitation tube check valve housing so when pulled a 7/32 of an inch, it pushes the tube into the user's mouth. Cover of a religious tract VHS tape featuring the M17A2 used to portray the apocalyptic debasement of the human society. The tubing should be attached somewhere else then the cap. 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. Another possible solution would be to store the tubing somewhere else then the canteen cap. Language links are at the top of the page across from the title. 3 of the initialRotary-Actuated prototypes were procured for testing purposes. This was later modified to include its own air supply, leading to World War I era gas masks. THE FILTERS ARE NOT RETURNABLE. All items except the voicemitter cover also fit the M17 (which has no drinking tube) The ABC-M17 was used by civilian law enforcement agencies for crowd control operations when protection from tear gas was required. In summer and autumn 1915, Edward Harrison, Bertram Lambert and John Sadd developed the Large Box Respirator. Although the ABC-M17 was associated with tunnel rats, the less bulky and more comfortable M28 riot control mask, nicknamed the "Grasshopper Mask", took over that role in 1968. It was believed that the drink tube was missing or poorly adjusted in the affected masks causing service members to over-torque the lever in frustration. 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.

In Europe and jurisdictions with similar rules such as Russia and Australia, filter types are given suffix numbers to indicate their capacity. (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. 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. The eye lenses on the MP-4 are slightly farther apart when compared to the original M17. 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. Filters will clog up, substrates for absorption will fill up, and reactive filters will run out of reactive substances. Though it was quickly removed from the design within a year or two of the introduction of the ABC-M17. The M17 has appeared in some post-apocalyptic art and comics throughout the 1970s and 1980s. The tape is part of a six VHS tape set, published in 2001 by Dr. Ed Hindson and the Jerry Falwell Industries. This would be repeated after every use and after every cleaning of the mask to help keep the masks lenses from fogging while it was being worn. It is unclear as of currently if this manufacturer made face blanks or if it only made outlet valve covers. 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 filter cartridge is connected via a flexible hose. Filtration may be aided with an air pump to improve wearer comfort.

Early versions were constructed by the Scottish chemist John Stenhouse in 1854[20] and the physicist John Tyndall in the 1870s. 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. WebThe M17 Protective Mask is a series of gas masks that were designed and produced in 1959 (as a replacement of the M-9 gas mask) to provide protection from all types of known chemical and biological agents present. It was a simple device consisting of a cotton hood with two hoses which hung down to the floor, allowing the wearer to breathe the safer air found there. Photos of troops wearing the M17A2 mask were run in newspapers and magazines and is closely identified with that war. It is not reliably known for how long the materials were used in filters. Consists of a book of perforated sheets of chemically treated, dye-impregnated paper. [citation needed]. Background A direct clone of the M17. The ABC in the nomenclature was an initialism for Atomic Biological Chemical. Identical to the M10 but includes a drinking system similar to the M17A1 and M17A2. 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. Firestone Tire & Rubber was contracted by the United States government to produce ABC-M17 face blanks starting in the third week of January, 1962 although by early 1963 Firestone's contract had ended. Unopened, vacuum sealed set of military filters for the US M17 gas mask.Filters will fit US M17 gas masks. [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. This likely was the design what made it into the final mask trials. [13] The inlet valve assembly snapped onto the connector ring of the filter. ADDRESSES ONLY! This kit was an olive drab canvas cover that goes over the inlet valves. Three approaches were investigated for means of moving the tube and mouthpiece into the user's mouth. A modern mask typically is constructed of an elastic polymer in various sizes. They had ended their contract by 1964 leaving MSA as the only remaining manufacturer of face blanks. WebA gas mask is a mask used to protect the wearer from inhaling airborne pollutants and toxic gases. Dont trust anything before 1980 and dont trust anything made by the soviets.

In the 1950s, the U.S. Army experimented with a variety of masks testing various filter technologies; many concepts that were tested were ultimately dropped. [1] The internal filter pouch solution was selected to meet this form factor and also eliminated the requirement to have different designs for the left and right-handed service members. The filter elements came in white airtight, vacuum-packed paper/foil laminated bags with labels indicating the filter nomenclature. Same as the M10 but made of black rubber and featuring a rubber, five-point head harness. Training M258 kits were available that substituted isopropyl alcohol in the packets instead of the actual decontamination solution. 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. With the nearly 30 year lifespan of of M17 series masks, there were many rubber lots and classifications, whether experimental or not. The mask carrier for the M17 series mask was a heavy cotton canvass, olive drab colored bag with nylon webbing and. The filter elements were designated M13 and were improved over time to the M13A1 and M13A2. [29] Macpherson presented his idea to the British War Office Anti-Gas Department on May 10, 1915; prototypes were developed soon after. These kits were issued with the M17 series protective masks until it was superseded my the in the early 1960s by the ABC-M13 Individual Decontaminating And Re-Impregnating Kit. series mask, M17 series masks began to flood the secondary market. After a mask is fitted, it is often tested by various challenge agents. [citation needed], Gas mask development since has mirrored the development of chemical agents in warfare, filling the need to protect against ever more deadly threats, biological weapons, and radioactive dust in the nuclear era. river crossing operations. This can be used to remove both particulate and gaseous hazards. A compact version, the Small Box Respirator, was made a universal issue from August 1916. (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. 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. The filter is selected according to the toxic compound. The actual combat kit had an olive drab plastic carrier and olive drab colored packets. A relatively unknown manufacturer that has been seen on a few ABC-M17s outlet valve covers. Another model was also introduced at the same time called the E13R13. The M17A1 incorporates a quick couple connector that greatly reduces the risk of contamination when used with the compatible M1 Water Canteen Cap.

This was the initial design that influenced the contract. [40], Many civilians learned how to use gas masks through the civil defense department, but children received most gas mask education in school drills. Early on the M1 anti-dim cloth was used with ABC-M17 kits. Training compensates for this but untrained civilian users might end up being uninformed on proper use.

In 1990-1991 Gulf War brought a threat of the first large-scale chemical war since World War I to the United States and its coalition allies. Both CRDL and Westinghouse went to work at designing a mouthpiece that could be out of the way of the users mouth but also be able to be moved into the mouth when they desired to drink or resuscitate. The soldier giving aid ran the risk of encountering resistance from the airway of the casualty, pushing air back into his mask and breaking its seal. M-17 Repair and Replacement Parts and Accessories Corrective lens inserts are also available for users who require them. The final stage of the polycarbonate eye lens degradation is severe yellowing, crazing, and embrittlement of the lens material. The tubing connected to the canteen is too small in diameter to drink appropriately in a short time period. The later Triplex lens style (a cellulose acetate lens sandwiched between glass ones)[1] became more popular, and alongside plain cellulose acetate they became the standard into the 1930s. It does not protect against ammonia vapors or carbon monoxide. The most common type of respirator is a half-face, dual cartridge respirator. The bag was used in operations where the mask was likely to get wet; e.g. The tunnel networks were filled with riot control agents through CS grenades or micro pulverized CS agent dispersers. It is recommended that the mask should utilize a rotary shutoff valve style instead. The E13-series masks tested these various configurations. The tubing size should be changed from a minimum 3/32 inch diameter to a inch minimum diameter. A voice diaphragm was also a design requirement to aid in battlefield speech communications in a contaminated environment. May fit foreign varients. This mask was later used widely in industry. The second initial design incorporated a device that had a singular mouthpiece permanently fixed in a static position inside the wearer's mouth. 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. [32] This canister gas mask had a tin can containing the absorbent materials by a hose and began to be issued in February 1916.
