Mass Decontamination
Mass decontamination (abbreviated mass decon) is the decontamination of large numbers of people, in the event of industrial, accidental, or intentional contamination by toxic, infective, caustic, polluted, or otherwise unhealthful or damaging substances. Mass hysteria and security aspects Scenes of ''mass contamination'' are often scenes of collective hysteria, with hundreds or thousands of victims in a state of panic. Therefore, mass decontamination may require police, security, or rescue supervision to help control panic and keep order. Under these circumstances, mass decon can take on some features of mass arrests, with victims forcibly rounded up, then treated inside impromptu detention areas. Successful municipal decontaminations are greatly aided by a close collaboration between police and fire departments. An organised, informed and aware populace can be better prepared for possible emergencies, and is less likely to panic. In some situations volunteers may be needed t ...

Decontamination
Decontamination (sometimes abbreviated as decon, dcon, or decontam) is the process of removing contaminants on an object or area, including chemicals, micro-organisms or radioactive substances. This may be achieved by chemical reaction, disinfection or physical removal. It refers to specific action taken to reduce the hazard posed by such contaminants, as opposed to general cleaning. Decontamination is most commonly used in medical environments, including dentistry, surgery and veterinary science, in the process of food preparation, in environmental science, and in forensic science.

Collective Hysteria
Mass psychogenic illness (MPI), also called mass sociogenic illness, mass psychogenic disorder, epidemic hysteria, or mass hysteria, involves the spread of illness symptoms through a population where there is no infectious agent responsible for contagion. It is the rapid spread of illness signs and symptoms affecting members of a cohesive group, originating from a nervous system disturbance involving excitation, loss, or alteration of function, whereby physical complaints that are exhibited unconsciously have no corresponding organic causes. Causes MPI is distinct from other types of collective delusions by involving physical symptoms. It is not well understood and its causes are uncertain. Qualities of MPI outbreaks often include: *symptoms that have no plausible organic basis; *symptoms that are transient and benign; *symptoms with rapid onset and recovery; *occurrence in a segregated group; *the presence of extraordinary anxiety; *symptoms that are spread via sight, sound or ...

Panic
Panic is a sudden sensation of fear, which is so strong as to dominate or prevent reason and logical thinking, replacing it with overwhelming feelings of anxiety and frantic agitation consistent with an animalistic fight-or-flight reaction. Panic may occur singularly in individuals or manifest suddenly in large groups as mass panic (closely related to herd behavior). Etymology The word "panic" derives from antiquity and is a tribute to the ancient god Pan. One of the many gods in the mythology of ancient Greece, Pan was the god of shepherds and of woods and pastures. The Greeks believed that he often wandered peacefully through the woods, playing a pipe, but when accidentally awakened from his noontime nap he could give a great shout that would cause flocks to stampede. From this aspect of Pan's nature Greek authors derived the word ''panikos'', “sudden fear,” the ultimate source of the English word: "panic". The Greek term indicates the feeling of total fear that i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Emergency Management Agency
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President that FEMA and the federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle ''Columbia'' in the 2003 return-flight disaster. While on-th ...

Decontamination Foam
Decontamination foam (known commonly as decon foam) is a spray-on cleaning solution used on surfaces that have been contaminated with biological or chemical agents (e.g., chemical warfare agents, anthrax spores or other toxic industrial materials). Decon foam has been found to make numerous chemical and biological agents harmless. It is also intended for use in areas where large numbers of people have possibly been contaminated (e.g. at conventions, airports, concerts). Composition The composition of decontamination foams is essentially water and a surfactant, creating an aqueous film forming foam that various reactive chemicals are then added, diminishing the amount of contaminants adhering to a surface and forming less hazardous products. Common reactants are hydrogen peroxide and quaternary ammonium complexes. Decon foam often comes in multiple bottles, that, when mixed, combine to form the decontamination solution. The bottles should be kept separate until needed as the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contamination Control
Contamination control is the generic term for all activities aiming to control the existence, growth and proliferation of contamination in certain areas. Contamination control may refer to the atmosphere as well as to surfaces, to particulate matter as well as to microbes and to contamination prevention as well as to decontamination. Function The aim of all contamination control activities is to permanently ensure a sufficient level of cleanliness in controlled environments. This is accomplished by maintaining, reducing, or eradicating viable and non-viable contamination for either sanitary purposes or in order to maintain an efficient rate of production. Usage One of the most common environments that incorporates contamination control into its standards protocol is the cleanroom. There are many preventive procedures in place within a cleanroom environment. They include subjecting cleanroom staff to strict clothing regulations, and there is often a gowning room where the s ...
