Crowd control can involve privately hired security guards as well as police officers. Crowd control is often used at large, public gatherings like street fairs, music festivals, stadiums and public demonstrations. At some events, security guards and police use metal detectors and sniffer dogs to prevent weapons and drugs being brought into a venue. Equipment Materials such as stanchions, crowd control barriers, fences and decals painted on the ground can be used to direct a crowd. A common method of crowd control is to use high visibility fencing to divert and corral pedestrian traffic to safety when there is any potential threat ...

Detection Dog
A detection dog or sniffer dog is a dog that is trained to use its senses to detect substances such as explosives, illegal drugs, wildlife scat, semen, currency, blood, and contraband electronics such as illicit mobile phones. The sense most used by detection dogs is smell. Hunting dogs that search for game, and search and rescue dogs that work to find missing humans are generally not considered detection dogs but fit instead under their own categories. There is some overlap, as in the case of cadaver dogs, trained to search for human remains. A police dog is essentially a detection dog that is used as a resource, for police in specific scenarios such as conducting drug raids, finding missing criminals, and locating stashed currency. Frequently, detection dogs are thought to be used for law enforcement purposes. Experts say that dog-sniff evidence should not be used in the criminal justice system, pointing to wrongful convictions, human biases that skew animal behavior, and the ...

Tear Gas
Tear gas, also known as a lachrymatory agent or lachrymator (), sometimes colloquially known as "mace" after the Mace (spray), early commercial self-defense spray, is a chemical weapon that stimulates the nerves of the lacrimal gland in the eye to produce tears. In addition, it can cause severe eye and respiratory pain, skin irritation, bleeding, and blindness. Common lachrymators both currently and formerly used as tear gas include pepper spray (OC gas), PAVA spray (nonivamide), CS gas, CR gas, CN gas (phenacyl chloride), bromoacetone, xylyl bromide, chloropicrin (PS gas) and Mace (spray), Mace (a branded mixture). While lachrymatory agents are commonly deployed for riot control by law enforcement and military personnel, its use in warfare is prohibited by various international treaties.E.g. the Geneva Protocol of 1925 prohibited the use of "asphyxiating gas, or any other kind of gas, liquids, substances or similar materials". During World War I, increasingly toxic and deadly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Demonstration (people)
A political demonstration is an action by a mass group or collection of groups of people in favor of a political or other cause or people partaking in a protest against a cause of concern; it often consists of walking in a mass march formation and either beginning with or meeting at a designated endpoint, or rally, in order to hear speakers. It is different from mass meeting. Demonstrations may include actions such as blockades and sit-ins. They can be either nonviolent or violent, with participants often referring to violent demonstrations as " militant." Depending on the circumstances, a demonstration may begin as nonviolent and escalate to violence. Law enforcement, such as riot police, may become involved in these situations. Police involvement at protests is ideally to protect the participants and their right to assemble. However, officers don't always fulfill this responsibility and it's well-documented that many cases of protest intervention result in power abus ...

Hillsborough Disaster
The Hillsborough disaster was a fatal crowd crush at a football match at Hillsborough Stadium in Sheffield, South Yorkshire, England, on 15 April 1989. It occurred during an FA Cup semi-final between Liverpool and Nottingham Forest in the two standing-only central pens within the Leppings Lane stand allocated to Liverpool supporters. Shortly before kick-off, police match commander David Duckenfield ordered exit gate C to be opened in an attempt to ease crowding, which led to an influx of supporters entering the pens. This resulted in overcrowding of those pens and the fatal crush; with a total of 97 fatalities and 766 injuries, the disaster is the deadliest in British sporting history. Ninety-four people died on the day; one more died in hospital days later, Tony Bland died in 1993, and in 2021, Andrew Devine, the 97th person died. Both Bland and Devine had suffered irreversible brain damage on the day. The match was abandoned and replayed at Old Trafford in Manchester on 7 ...

Entertainment
Entertainment is a form of activity that holds the attention and Interest (emotion), interest of an audience or gives pleasure and delight.

Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in Court (royal), royal courts, and developed into sophisticated forms over time, becoming available to all citizens. The process has been accelerated in modern times by an entertainment industry that records and sells entertainment products.

Cooling Fan
A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an '' impeller'', ''rotor'', or ''runner''. Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Mechanically, a fan can be any revolving vane, or vanes used for producing currents of air. Fans produce air flows with high volume and low pressure (although higher than ambient pressure), as opposed to compressors which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air-fluid stream, and devices that take advantage of this, such as anemometers and wind tu ...

Awning

The configuration of this structure is something of a truss, space frame or planar Framing (construction), frame.

Crowd Control Barrier
Crowd control barriers (also referred to as crowd control barricades, with some versions called a French barrier or bike rack in the USA, and mills barriers in Hong Kong) are commonly used at many public events. They are frequently visible at sporting events, parades, political rallies, demonstrations, and outdoor festivals. Event organizers, venue managers, and security personnel use barricades as part of their crowd management planning. History Nadar Brussels mayor Jules Anspach has been credited with the invention of the crowd control barrier for the occasion of the visit of the French photographer Nadar to Brussels. On his visit to Brussels with the balloon ''Géant'', on September 26, 1864, Anspach erected mobile barriers to keep the crowd at a safe distance. Up to this day, crowd control barriers are known in both Belgian Dutch and Belgian French as ''Nadar barriers''. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stanchion
A stanchion () is a sturdy upright fixture that provides support for some other object. It can be a permanent fixture. Types In architecture, stanchions are the upright iron bars in windows that pass through the eyes of the saddle bars or horizontal irons to steady the leadlight. The French call the latter ''traverses'', the stanchions ''montants'', and the whole arrangement ''armature''. Stanchions frequently finish with ornamental heads forged out of the iron. Stanchions are also the metal supporting members of lighting mounted from a lower elevation. This includes the metal inclined member for mounting a streetlight to a telephone or power pole, and the dedicated metal vertical support of a self-supporting or bottom-fed streetlight. In this case, the stanchion pole may double as the Electrical conduit, raceway for the electrical feed to the lighting. In industrial installations, walkway lighting may be mounted with a stanchion that is secured to a hand-rail. Stanchion lights ...
