The XM929/XM929E1, smoke is a 120mm mortar cartridge which utilizes White Phosphorus (WP) impregnated felt payload to provide obscuration screening on impact. This is white phosphorus. White phosphorus catches fire spontaneously in air, burning to make smoke of phosphorus(V) oxide. When you burn the striker, the phosphorus is vaporized and condenses into a solid on the cool metal surface. It exists in an amorphous form and found to be more stable than white phosphorus. It is a common allotrope of the chemical element phosphorus that has had extensive military use as an incendiary agent, an agent for creating smoke screens, and as an antipersonnel flaming component capable of causing severe burns. Red phosphorus is more stable, catching fire only above 240 degrees Celsius, and can be used in smoke bombs, but it won’t double as an incendiary. However, because white phosphorus reacts very quickly with oxygen in the air, it may not be found far away from sources of contamination. It uses 36 pellets that disperse and sit above ground giving a smokescreen over a wider area. White phosphorus is used in the manufacture of munitions, pyrotechnics, explosives, smoke bombs, in artificial fertilizers, and rodenticides. Red phosphorus (RP) and the coated RP with melamine formaldehyde resin (MFcP) were foamed with isocyanates to prepare polyurethane foam (PUF). Cartridge is ballistically similar to the M374A3 (HE) cartridge. The fate of white phosphorus smoke is similar to the fate of reaction products of white phosphorus vapor in air. The M34 White Phosphorus Smoke Grenade or "Whiskey Pete" was a smoke / incendiary grenade manufactured by Rocky Mountain Arsenal from the late 1950s and used by U.S. forces during the Vietnam War and was also used during the First Gulf War.The M34 WP Grenade replaced the World War II M15 WP grenade. Are there any white phosphorus munitions in the British Armed Forces? - This is a port of my work from Arma 2 and Unsung but updated to Arma 3 specs and standards. Smoke with toxic gas is the most fatal factor in a real fire. Summary [ hide ] 1 Physico-chemical characteristics 1 Formula: P4; 2 Allotropy; 2 Collection and use Satellite imagery shows environmental damage of reported white phosphorus use in Nagorno ... during the fire, and the aftermath. The fate of white phosphorus smoke is similar to the fate of reaction products of white phosphorus vapor in air. A search of MOD records has been undertaken and I can confirm that stocks of L84A2 red phosphorous smoke grenades are held but they are no longer used and are in the process of being disposed of. Used to screen, signal, and act as an incendiary. White phosphorus sample. White phosphorus was used most often during World War II in military formulations for smoke screens, marker shells, incendiaries, hand grenades, smoke markers, colored flares, and tracer bullets. Other common names include WP, and the slang term "Willie Pete," which is dated from its use in Vietnam, and is still sometimes used in military jargon. While safety matches contain red phosphorus instead of white phosphorus, the element is converted to white phosphorus vapor. Acute (short-term) oral exposure to high levels of white phosphorus in White phosphorus glows when exposed to air. Such a smoke screen is usually used to conceal the movements or location of military units. Smoke, immidiate I believe as it provides a smoke screen after the bang, rather than having to wait for it to biuld. Training Practice (TP). White phosphorus vapor in air reacts with oxygen and is changed to relatively harmless chemicals within minutes. Military application of phosphorus smokes for screening during a military operation can make use of either white phosphorus (WP) or red phosphorus (RP). It contains white phosphorus that produces white smoke on contact with air. Illumination. When Smoke ammunition is used it might be possible that the formed smoke components are adsorbed by these small sand particle and when the are inhaled cause great damage to the lung cells. They have been replaced by the L84A3 red phosphorous smoke grenade. White phosphorus is used in military applications as incendiary bombs, for smoke-screening as smoke pots and smoke bombs, and in tracer ammunition. Red Phosphorus (RP), White Phosphorus (WP). The red phosphorus smoke varient gives longer lasting and more effective smoke production with lower toxicity that white phosphorus. Phosphorus is a prohibited weapon under international law but is allowed to illuminate battlefields and for use as a smoke screen. The type of phosphorus in the striker on matchboxes is red phosphorus. When white phosphorus is heated in an alkali, it disproportionates to produce hypophosphites and phosphine. It is used in organic synthesis and chemical warfare including igniters, incendiaries, screening smoke ammunition and smoke signal. Obscurants, such as phosphorus smokes, are effective in blocking the transmission of a particular part of the electromagnetic spectrum, such as visible light, infrared light, or microwaves. Effective smoke area - 120 secs; Range - 5,375m However, particles in the air may have a protective coating that makes them unreactive for a longer time. Flame Retardants Despite being a flammable material, red phosphorus can act as a flame retardant when added to plastics, rubber, and resins. metal plate and sand) on the particle size of the formed red phosphorus smoke and the health effects of these smokes. He was given the signal to drop the bombs when the aircraft was just off the south coast of Japan and under attack by anti-aircraft fire and Japanese fighters. US-led forces in #Iraq and #Syria are accused of using white #phosphorus bombs. The 1-h LC50 was 271 (19670) for the mouse, 1217 (970 1489) for the rat, 61 (520) for guinea pigs and 1689 (1200586) for rabbits (mg/m3, with 95% confidence limits). Red phosphorus is also used as a flame retardant … Thus, inhaling the fumes from matches isn't exactly healthy. waste sites that contain white phosphorus are also potential sources of exposure to people. Erwin’s was to drop phosphorus smoke bombs through a chute in the aircraft’s floor when the lead plane reached a designated assembly area. When mixed with magnesium and a binder, red phosphorus can be used as a smoke device that can quickly create a smoke screen. White phosphorus is more reactive than red phosphorus. The M34 could be fired from a rifle grenade launcher using M2-series grenade … The acute inhalation toxicity of a red phosphorus smoke was studied by Ballantyne [17]. It is also used in the production of methamphetamine (commonly known as meth). :) - Napalm bomb and White Phosphorus Smoke … Practice items may or may not contain explosive sections such as propellant charges or spotting charges. White phosphorus is a material made from a common allotrope of the chemical element phosphorus that is used in smoke, tracer, illumination and incendiary munitions. The cartridge is painted light green and has red markings and one narrow yellow band. It achieves ranges from 300 - 7200 meters with the M120/M121 Battalion Mortar System. The cartridge uses the M205 propelling charge and is assembled with the M567 or M524-series fuze. White phosphorus is extremely toxic to humans, while other forms of phosphorus are much less toxic. If it burns in a little air, it produces poisonous phosphorus(III) oxide. White phosphorus. Napalm and Smoke Marker rockets by ANZACSAS Steve. It is not an offesive weapon and should not be used as such. A castable pyrotechnic white smoke composition which comprises red phosphorous, an alkali metal nitrate, magnesium and a suitable castable polymeric binder. A part of this research is to obtain insight in the contribution of different surfaces (e.g. environmental fate of white phosphorus/felt and red phosphorus/butyl rubber military screening smokes final report ronald j. spanggord robert rewick tsong-wen chou robert wilson r. thomas podoll theodore mill richard parnas robert platz daryl roberts n n 0') april 1985 supported by u.s. army medical research and development command Red Phosphorus for Use in Screening Smoke Compositions It has been known for many years that red phosphorus reacts with moist air to produce phosphorus oxyacids and phosphine. Training items are completely inert. Red phosphorus is essential for manufacturing matchbook strikers, flares, [1] safety matches, pharmaceutical grade and street methamphetamine, and is used in cap gun caps. Smoke. The match heads of safety matches contain sulfur (sometimes antimony III sulfide) and oxidizing agents (usually potassium chlorate ), with powdered glass, colorants, fillers, and a binder made of glue and … Used to illuminate, signal, and mark. The detailed mechanism remains unknown. Red phosphorus is the most common allotrope of phosphorus. White phosphorus (WP) is a flare- and smoke-producing incendiary device or smoke-screening agent that is made from a common allotrope of the chemical element phosphorus. White phosphorus bombs and shells are incendiary weapons, but can also be used as offensive anti-personnel flame compounds capable of causing serious burns or death. The hospital’s deputy director, Karine Babayan said the injuries were consistent with the use of phosphorus or were caused by another “chemical agent”. Phosphorus is a chemical element that can take several forms, called allotropes. This variant is in service with Armed Forces around the world.
