M40 Field Protective Mask
The M40 field protective mask was one of various protective masks used by the United States Armed Forces and its allies to protect from field concentrations of chemical and biological agents, along with radiological fallout particles. It is not effective in an oxygen deficient environment or against ammonia. History The M40 was the result of a program in the 1980s to develop a successor to the M17-series protective masks which had been in service with the US armed forces since 1959. The M40 was to be a return to conventional protective mask design with an external side-mounted filter canister, rather than the internal cheek filters of the M17, which were awkward to change, especially in a contaminated environment. The final prototype, the XM40, was approved for service and then designated the M40. The M40 was phased into service with the U.S. Army and Marine Corps in the mid-1990s, with another new design, the MCU-2/P also replacing the older M17 in service with the U.S ...

Gas Mask
A gas mask is a mask used to protect the wearer from inhaling airborne pollutants and toxic gases. 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. 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. The gas mask only protects the user from digesting, inhaling, and contact through the eyes (many agents affect through eye contact). Most combined gas mask filters will last around 8 hours in a biological or chemical situation. Filters against specific chemical agents can last up to 20 hours. Airborne toxic materials may be gaseous (for example, chlorine or mustard gas), or particulates (such as biological agents). Many filters provide protection from both types. The first gas masks mostly used circular lenses made of glass, mica or cellulose acetate to allow vision. Glass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blister Agent
A blister agent (or vesicant), is a chemical compound that causes severe skin, eye and mucosal pain and irritation. They are named for their ability to cause severe chemical burns, resulting in painful water blisters on the bodies of those affected. Although the term is often used in connection with large-scale burns caused by chemical spills or chemical warfare agents, some naturally occurring substances such as are also blister-producing agents (vesicants).

Blood Agent
A blood agent is a toxic chemical agent that affects the body by being absorbed into the blood. Blood agents are fast-acting, potentially lethal poisons that typically manifest at room temperature as volatile colorless gases with a faint odor. They are either cyanide- or arsenic-based. Exposure Blood agents work through inhalation or ingestion. As chemical weapons, blood agents are typically disseminated as aerosols and take effect through inhalation. Due to their volatility, they are more toxic in confined areas than in open areas. Cyanide compounds occur in small amounts in the natural environment and in cigarette smoke. They are also used in several industrial processes and as pesticides. Cyanides are released when synthetic fabrics or polyurethane burn, and may thus contribute to fire-related deaths.Walsh, 151. Arsine gas, formed when arsenic encounters an acid, is used as a pesticide and in the semiconductor industry; most exposures to it occur accidentally in the work ...

Philippine Marine Corps
The Philippine Marine Corps (PMC) ( fil, Hukbong Kawal Pandagat ng Pilipinas) is the marine corps of the Philippines, a naval infantry force under the command of the Philippine Navy. The PMC conducts amphibious, expeditionary, and special operations missions. History — LTSG Manuel Gomez's mission on the formation of the Philippine Marine Corps in 1950 On orders from President Elpidio Quirino and Ramon Magsaysay, then Secretary of National Defense, the Corps was organized on November 7, 1950, as A Company of the Philippine Fleet's 1st Marine Battalion and then headquartered in Cavite City, in Naval Base Cavite.

M50 Joint Service General Purpose Mask
The M50 series protective mask consisting of the M50 and M51 variants, officially known as the Joint Service General Purpose (JSGPM) is a lightweight, protective mask system consisting of the mask, a mask carrier, and additional accessories. It was adopted by the U.S. military in 2006 and is manufactured by Avon Rubber. The mask was designed/made to incorporate the state-of-the-art technologies to protect United States Armed Forces and the allied forces from current and anticipated threats from all types of weapons of mass destruction. It is an above-the-neck, chemical-biological (CB) respirator that protects against battlefield concentrations of CB agents, toxins, toxic industrial materials and radioactive particulate matter. The M50/51 masks replace the M40 field protective mask and M42, MCU-2/P series masks and the M45 of the Land Warrior Program. There are two mask variants: M50 (ground and shipboard use) and M51 (ground vehicle use). History The M50 series mask entered se ...

Armoured Fighting Vehicle
An armoured fighting vehicle (AFV) is an armed combat vehicle protected by armour, generally combining operational mobility with offensive and defensive capabilities. AFVs can be wheeled or tracked. Examples of AFVs are tanks, armoured cars, assault guns, self-propelled guns, infantry fighting vehicles, and armoured personnel carriers. Armoured fighting vehicles are classified according to their characteristics and intended role on the battlefield. The classifications are not absolute; two countries may classify the same vehicle differently, and the criteria change over time. For example, relatively lightly armed armoured personnel carriers were largely superseded by infantry fighting vehicles with much heavier armament in a similar role. Successful designs are often adapted to a wide variety of applications. For example, the MOWAG Piranha, originally designed as an APC, has been adapted to fill numerous roles such as a mortar carrier, infantry fighting vehicle, and ass ...

Butyl Rubber
Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C4H8)n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based. Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene. Structurally, polyisobutylene resembles polypropylene, but has two methyl groups substituted on every other carbon atom, rather than one. Polyisobutylene is a colorless to light yellow viscoelastic material. It is generally odorless and tasteless, though it may exhibit a slight characteristic odor. Properties Butyl rubber has excellent impermeability to gas diffusion, and the long polyisobutylene segments of its polymer chains give it good flex properties. The formula for PIB is: –(–CH2–C(CH3)2–)n– The formula for IIR is: It can be made from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riot Control Agent
Riot control measures are used by law enforcement, military, paramilitary or security forces to control, disperse, and arrest people who are involved in a riot, unlawful demonstration or unlawful protest. If a riot is spontaneous and irrational, actions which cause people to stop and think for a moment (e.g. loud noises or issuing instructions in a calm tone) can be enough to stop it. However, these methods usually fail when there is severe anger with a legitimate cause, or the riot was planned or organized. Riot control personnel have long used less lethal weapons such as batons and whips to disperse crowds and detain rioters. Since the 1980s, riot control officers have also used tear gas, pepper spray, rubber bullets, stun grenades, and electric tasers. In some cases, riot squads may also use Long Range Acoustic Devices, water cannons, armoured fighting vehicles, aerial surveillance, police dogs or mounted police on horses. Persons performing riot control typical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
