Collective Protection
Collective protection is used for group protection of personnel in a nuclear, biological or chemical event, (NBC). Collective protection is an important aspect of fixed site defense. Ideally, it provides a contaminate free environment for people, allowing relief from the continuous wearing of gas masks and other MOPP equipment. The basic concept applied for collective protection is overpressure and filtration. By filtering the incoming air to the shelter or protected space and maintaining higher internal air pressure than the external pressure, the contaminated external air is prevented from infiltrating the shelter or protected space and results in a toxic free area (TFA) for work and relief from wearing MOPP equipment. The most critical component of any collective protection area is the air filtration system. The US Army Corps of Engineers has published stringent standards for the construction and performance of this type of equipment. See also * Fallout shelter A fall ...

Weapon Of Mass Destruction
A weapon of mass destruction (WMD) is a biological, chemical, radiological, nuclear, or any other weapon that can kill or significantly harm many people or cause great damage to artificial structures (e.g., buildings), natural structures (e.g., mountains), or the biosphere. The scope and usage of the term has evolved and been disputed, often signifying more politically than technically. Originally coined in reference to aerial bombing with chemical explosives during World War II, it has later come to refer to large-scale weaponry of warfare-related technologies, such as biological, chemical, radiological, or nuclear warfare. Early usage The first use of the term "weapon of mass destruction" on record is by Cosmo Gordon Lang, Archbishop of Canterbury, in 1937 in reference to the bombing of Guernica, Spain: At the time, nuclear weapons had not been developed fully. Japan conducted research on biological weapons, and chemical weapons had seen wide battlefield use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOPP (protective Gear)
MOPP (Mission Oriented Protective Posture; pronounced "mop") is protective gear used by U.S. military personnel in a toxic environment, for example, during a chemical, biological, radiological, or nuclear (CBRN) strike. Protective equipment * protective mask – Commonly referred to as a gas mask or pro mask. It is designed to filter harmful chemical and biological agents, as well as irradiated particles from the air to allow the wearer to breathe safely. No protective masks filter out gases such as carbon monoxide, and in situations requiring that level of protection, external breathing apparatus is employed. * Mask carrier – Protects the mask from damage. It is usually worn as part of battle gear for easy access and usually contains a technical manual, extra filter, spare parts, chemical detection papers, and nerve agent antidote kits (NAAK). * Over garments – Joint Service Lightweight Integrated Suit Technology (JSLIST) Specially designed clothing to be worn over the n ...

Overpressure (CBRN Protection)
An overpressure protection system is one designed to protect an individual or group of individuals in a chemical, biological, radiological and nuclear ( CBRN) environment. The two parts of the system are a safe area which as far as possible is sealed from possible contaminated air and an air filtration system which will filter out all possible toxins. Air pumps force clean air through the filters into the safe area such that the air pressure within the safe area will always be higher than that outside of the safe area. This pressure differential means that any flows of air will always be from the safe area to the outside, preventing the ingress of toxins. The safe area may be as small as a protective hood for an individual, to a full body hazmat suit, to a fallout shelter or warship. Most modern armoured fighting vehicles will have such a system with the safe area being the crew and passenger compartments, these systems being first adopted to protect against poison gas attack. ...

United States Army Corps Of Engineers
The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army. A direct reporting unit (DRU), it has three primary mission areas: Engineer Regiment, military construction, and civil works. USACE has 37,000 civilian and military personnel, making it one of the world's largest public engineering, design, and construction management agencies. The USACE workforce is approximately 97% civilian, 3% active duty military. The civilian workforce is mainly located in the United States, Europe and in select Middle East office locations. Civilians do not function as active duty military and are not required to be in active war and combat zones; however, volunteer (with pay) opportunities do exist for civilians to do so. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the chief of engineers/commanding general. The chief of engineers commands the Engineer Regiment, comprisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fallout Shelter
A fallout shelter is an enclosed space specially designated to protect occupants from radioactive debris or fallout resulting from a nuclear explosion. Many such shelters were constructed as civil defense measures during the Cold War. During a nuclear explosion, matter vaporized in the resulting fireball is exposed to neutrons from the explosion, absorbs them, and becomes radioactive. When this material condenses in the rain, it forms dust and light sandy materials that resemble ground pumice. The fallout emits alpha and beta particles, as well as gamma rays. Much of this highly radioactive material falls to Earth, subjecting anything within the line of sight to radiation, becoming a significant hazard. A fallout shelter is designed to allow its occupants to minimize exposure to harmful fallout until radioactivity has decayed to a safer level, over a few weeks or months. Principle A fallout shelter is designed to protect its occupants from: * the mechanical and thermal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
