Lockdown (other)
A lockdown () is a restriction policy for people, community or a country to stay where they are, usually due to specific risks (such as COVID-19) that could possibly harm the people if they move and interact freely. The term is used for a prison protocol that usually prevents people, information or objects from leaving an area. The protocol can usually only be initiated by someone in a position of authority. A lockdown can also be used to protect people inside a facility or, for example, a computing system, from a threat or other external event. In buildings doors leading outside are usually locked so that no person may enter or exit. Types Lockdowns may be adopted as a preventative measure or in response to a crisis as an emergency measure. Preventive lockdown A preventive lockdown is a preemptive action plan implemented to address an unusual scenario or a weakness in system to preempt any danger to ensure the safety and security of people, organisation and system.

COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. COVID-19 transmits when people breathe in air contaminated by droplets and ...

COVID-19 Community Quarantines In The Philippines
COVID-19 community quarantines in the Philippines were series of stay-at-home orders and ''cordon sanitaire'' measures that have been implemented by the government of the Philippines through its Inter-Agency Task Force for the Management of Emerging Infectious Diseases (IATF-EID). As of November 2021, under the original classification system that was enacted in 2020, there were four main quarantine tiers. In Metro Manila there is now an alert level system (ALS) which has been introduced in September 2021 and it is already in place. As of November 2021, all regions of the country have been covered by the ALS system, which has become the national standard. In the original classification system, the strictest community quarantines is the "enhanced community quarantine" (ECQ), which effectively is a total lockdown. According to the ALS, there are five tiers of alert level, with alert level 1 being the most lenient and alert level 5 being the most strict. Background As a result ...

Civil Disturbance
Civil disorder, also known as civil disturbance, civil unrest, or social unrest is a situation arising from a mass act of civil disobedience (such as a demonstration, riot, strike, or unlawful assembly) in which law enforcement has difficulty maintaining their authority. Engagement According to the U.S. Code, a person is engaged in civil disorder if they - Causes Any number of things may cause civil disorder, whether it is a single cause or a combination of causes; however, most are born from political grievances, economic disparities, social discord, but historically have been the result of long-standing oppression by a group of people towards another. Civil disorder arising from political grievances can include a range of events, from a simple protest to a mass civil disobedience. These events can be spontaneous, but can also be planned. These events can turn violent when agitators and law enforcers overreact. Civil disorder has in history arisen from economic disputes ...

Active Shooter
Active shooter or active killer describes the perpetrator of a type of mass murder marked by rapidity, scale, randomness, and often suicide. The United States Department of Homeland Security defines an ''active shooter'' as "an individual actively engaged in killing or attempting to kill people in a confined and populated area; in most cases, active shooters use firearms and there is no pattern or method to this selection of victims." Terminology In police training manuals, the police response to an active shooter scenario is different from hostage rescue and barricaded suspect situations. Police officers responding to an armed barricaded suspect often deploy with the intention of containing the suspect within a perimeter, gaining information about the situation, attempting negotiation with the suspect, and waiting for specialist teams like SWAT. If police officers believe that a shooter intends to kill as many people as possible before killing themselves, they may use a ta ...

Hostage Crisis
A hostage is a person seized by an abductor in order to compel another party, one which places a high value on the liberty, well-being and safety of the person seized, such as a relative, employer, law enforcement or government to act, or refrain from acting, in a certain way, often under threat of serious physical harm or death to the hostage(s) after expiration of an ultimatum. The ''Encyclopædia Britannica Eleventh Edition'' (1910-1911) defines a hostage as "a person who is handed over by one of two belligerent parties to the other or seized as security for the carrying out of an agreement, or as a preventive measure against certain acts of war." A party who seizes one or more hostages is known as a hostage-taker; if the hostages are present voluntarily, then the receiver is known as a host. In civil society, along with kidnapping for ransom and human trafficking (often willing to ransom its captives when lucrative or to trade on influence), hostage taking is a cri ...

Bomb Threat
A bomb threat or bomb scare is a threat, usually verbal or written, to detonate an explosive or incendiary device to cause property damage, death, injuries, and/or incite fear, whether or not such a device actually exists. History Bomb threats were used to incite fear and violence during the American Civil Rights Movement, during which leader of the movement Martin Luther King Jr. received multiple bomb threats during public addresses, and schools forced to integrate faced strong opposition, resulting in 43 bomb threats against Central High School in Arkansas being broadcast on TV and the radio. Motivations Supposed motives for bomb threats include: "humor, self assertion, anger, manipulation, aggression, hate and devaluation, omnipotence, fantasy, psychotic distortion, ideology, retaliation," and creating chaos. Many of the motives based on personal emotion are speculative. Many bomb threats that are not pranks are made as parts of other crimes, such as extortion, arson, o ...

Fire
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's Intensity (heat transfer), intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flooding
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting in some of t ...

Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Failure
A power outage (also called a powercut, a power out, a power failure, a power blackout, a power loss, or a blackout) is the loss of the electrical power network supply to an end user. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power failures are particularly critical at sites where the environment and public safety are at risk. Institutions such as hospitals, sewage treatment plants, and mines will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost. Other critical systems, such as telecommunication, are also required to have emergency power. The battery room of a telephone exchange usually has arrays of lead–acid batteries for backup and also a socket f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prison Riots
A prison riot is an act of concerted defiance or disorder by a group of prisoners against the prison administrators, prison officers, or other groups of prisoners. Prison riots have not been the subject of many academic studies or research inquiries. The analyses that do exist tend to emphasize a connection between prison conditions (such as prison overcrowding) and riots, or discuss the dynamics of the modern prison riot. In addition, a large proportion of academic studies concentrate on specific cases of prison riots. Other recent research analyzes and examines prison strikes and reports of contention with inmate workers. Prison conditions In the late 20th century, the analyses and conclusions presented to account for prison disturbances and riots began to shift and change based upon new studies and research. Initially, prison riots were considered irrational actions on the behalf of the prisoners. Nevertheless, there has been a shift in the form of explanation as external con ...

September 11, 2001 Attacks
The September 11 attacks, commonly known as 9/11, were four coordinated suicide terrorist attacks carried out by al-Qaeda against the United States on Tuesday, September 11, 2001. That morning, nineteen terrorists hijacked four commercial airliners scheduled to travel from the Northeastern United States to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City, and the third plane into the Pentagon (the headquarters of the United States military) in Arlington County, Virginia. The fourth plane was intended to hit a federal government building in Washington, D.C., but crashed in a field following a passenger revolt. The attacks killed nearly 3,000 people and instigated the war on terror. The first impact was that of American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 a.m. Seventeen minutes later, at 9:03, the World Trade Center’s So ...
