MSA (Mine Safety Appliances) was the first and main contractor for the M17 series masks. Filters will clog up, substrates for absorption will fill up, and reactive filters will run out of reactive substances. Some models contain drinking tubes which may be connected to a water bottle. The innovative drinking system of the M17A1 and M17A2 operated with a small lever on the outlet valve assembly. All items fit the M17A1 and the M17A2. August 1975, 50 pages, 4" x 5-3/4".

Filters will fit US M17 gas masks. [24] The M258A1 improved on the design of the kit by incorporating the decontamination solutions in individually sealed packets. 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. However, a well trained soldier could accomplish the task in as few as five minutes. All three of these designs were delivered to CRDL and tested at the Fort Detrick Army Biological Laboratories. M17A1 with the yellow valve for the drinking tube. Military planners deemed the M9 as too bulky for modern combat due to the large filter canister mounted on the side of the face blank (although M9 series masks would be used for special purposes well through the mid-1990s).

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 concept and execution were problematic as the use of the tube could expose the wearer to contamination. The M1A1 waterproof bag was a heavy-duty vinyl bag supplied with rubber bands that were designed to accommodate the M17 series mask with attached hood. Training compensates for this but untrained civilian users might end up being uninformed on proper use. The photo was taken of a Viet Nam War era diorama at the National Museum of the Marine Corps, Triangle, Virginia. 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. The final mask designs that resulted from these experiments were two models based off of the third developmental model. A contract was secured with Westinghouse Electric Co. UnderSeas Division on April 1st, 1964. Such lack of instructions can only increase the appreciation for today's included instruction manuals on a lot of filter packages. [13] The booklet consisted of 25 sheets of detector paper but each sheet was bifurcated so it allowed up to 50 tests for a liquid agent. The ABC-M17 was used by civilian law enforcement agencies for crowd control operations when protection from tear gas was required.

The two masks that made it to the final testing phases were two masks, the E13R12 and E13R13. 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. 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. Although there was little risk of the use of lethal chemical warfare agents by either side, the American Army made extensive use of riot control agents (most commonly, CS) during certain missions. to see larger image 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.

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. This theoretically overpressurized the hood to make the infiltration of chemical warfare agent vapors less likely. Due of this short production run, Firestone face blanks are the rarest with only a year of production. Voice mitter outlet valve cover, fit M17A1-M17A2. Later, stronger polycarbonate came into use.

During the Cold War, it was seen as inevitable that there would be a constant NBC threat on the battlefield and so troops needed protection in which they could remain fully functional; thus, protective gear and especially gas masks have evolved to incorporate innovations in terms of increasing user comfort and compatibility with other equipment (from drinking devices to artificial respiration tubes, to communications systems etc.). Earlier prototype model, possibly an E13R8. The M17 has appeared in some post-apocalyptic art and comics throughout the 1970s and 1980s. 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. The user may be exposed to many types of toxic material. While more comfortable for the wearer, the design was rejected since there was the concern of penetration of liquid persistent chemical warfare agents such as VX. According to Popular Mechanics, "The common sponge was used in ancient Greece as a gas mask"[15] In 1785, Jean-Franois Piltre de Rozier invented a respirator. The M17A2 is shown above.

The E13R4 mask had integral cheek-mounted filters and was considered superior since the mask did not require a separate filter connected by a hose and accommodated left and right-handed soldiers without modification. This can be used to remove both particulate and gaseous hazards. Write your own review. The final mask, adopted as the M17, was a slightly modified E13R9. 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. [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. Most gas masks are also respirators, though the word gas mask is often used to refer to military equipment (such as a field protective mask), the scope used in this article. 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. After WWII, and with the cold war between the US and the USSR looming, it was clear to war planners that any future war would quickly escalate from conventional to chemical and biological war. The US C2 canister (black) contains hexavalent chromium; studies by the U.S. Army Chemical Corps found that the level in the filter was acceptable, but suggest caution when using, as it is a carcinogen.[5]. Filters against specific chemical agents can last up to 20 hours. 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.

The outserts were not a basic issue item supplied with the mask and had to be ordered separately when missions in sunny areas were anticipated. That is when the rubber of the mask retains a memory of a position when stored in that position for a long period of time. 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. Also, it had replaceable plastic lenses. 4.7 out of 5 stars 482. 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. The prong type was only available with the M17A1 and M17A2 versions of the mask.

[6] In the US, only the particle part is further classified by NIOSH air filtration ratings. 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. Sure you can get a U.S M9A1 from the 50s and wear it fine. The first gas masks mostly used circular lenses made of glass, mica or cellulose acetate to allow vision. 1 PAIR GREEN (NIGHT) [21] Another early design was the "Safety Hood and Smoke Protector" invented by Garrett Morgan in 1912, and patented in 1914. Corrective lens inserts are also available for users who require them. Carey, C., 1998. Same as the M10 but made of black rubber and featuring a rubber, five-point head harness. The winter configuration had the hood under the outlet valve allowing the exhaled air to escape to the atmosphere. Training M258 kits were available that substituted isopropyl alcohol in the packets instead of the actual decontamination solution. [citation needed]. More thought should be put into the design of the tubing and its attachment to the canteen. These outserts provide protection from ruby and neodymium type lasers. The carrier had a large pouch that would contain the mask with a small pouch inside the main compartment designed to house the M1 eye lens outserts when not in use. 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 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. For example, if the target particles are positively charged, a negatively charged substrate may be used. 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. [21] The hood had a plastic fastener for the neck strap similar to the M4 hood for the M9A1 mask. Because of this, MSA is the most common manufacturer of face blanks with most ABC-M17s and all M17A1/A2s being produced by them. A few examples of this mask were made with clear silicone rubber. Because of this, the inserts do not offer ballistic protection. It is not reliably known for how long the materials were used in filters. The UK HSE textbook recommends limiting the use of respirators without air supply (that is, not PAPR) to one hour.[14]. [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.
