Exclusion zone

For the interface layer in water, seeExclusion zone (physics).

Anexclusion zoneis a territorial division established for various, case-specific purposes.

Per theUnited States Department of Defense,an exclusion zone is a territory where an authority prohibits specific activities in a specific geographic area (seemilitary exclusion zone).These temporary or permanent zones are created for control of populations for safety, crowd control, or military purposes, or as aborder zone.

Nuclear disaster exclusion zones

Large-scale geographic exclusion zones have been established after major disasters in which radioactive particles were released into the environment:

• Kyshtym disaster(1957)
  • East Ural Nature Reserve–Russia,established 1968.
• Chernobyl disaster(1986)
  • Chernobyl Exclusion Zone–Ukraine,established 1986.
  • Polesie State Radioecological Reserve–Belarus,established 1988.
• Fukushima nuclear disaster(2011)
  • Fukushima Exclusion Zone–Japan,established 2011.

Ordnance exclusion zones

• Zone Rouge– France, established 1919

Maritime gas leak exclusion zones

Two exclusion zones (5 nautical miles (9.3 km; 5.8 mi) and 7 nautical miles (13 km; 8.1 mi)) were established temporarily in theBaltic Seafollowing the2022 Nord Stream pipeline sabotage.Dangers to navigation included loss of buoyancy inside the gas plumes and accidental ignition of the gas.

Border zones

Border zonesare areas where movement, property ownership or other activity is prohibited or restricted by legislation. Unlike regular territory, border zones are under administrative control of the border authorities. Entrance is generally only with an individual permit. Entering a border zone without authorization is a crime or misdemeanor and grounds for arrest. Border zones are instituted to pinpoint illegal intruders, conceal and obscure and prevent interference with border security procedures and equipment, and thus aid border guards with their work. For example, Russia maintainssizable border zones.

Natural disaster exclusion zones

Similarly, exclusion zones have been established due to natural disasters. There is an exclusion zone on the island ofMontserrat,where the long-dormantSoufrière Hillsvolcano started erupting in 1995 and has continued erupting since. It encompasses the south part of the island, accounting for over half of its land mass and most areas of the island which were populated before the volcano erupted. The volcano destroyed the island's urban center and capitalPlymouth,as well as many other villages and neighborhoods. The zone is now strictly enforced; entry into most of the destroyed areas is prohibited, while some areas are subject to restrictions during volcanic activity or open only as a "daytime entry zone".

Rocket launches

Main article:Range safety

Before the launch of a missile or launch vehicle, the area surrounding the launch site and underneath the trajectory of the rocket, called the launch corridor, is cleared. That way, spectators, aviators, seamen and ground controllers are safe from a rocket launch, in particular when the rocket goes errant. Because the flight termination system destroys the rocket in that case, launches are scrubbed or postponed when someone or something enters the launch corridor to prevent damage or harm created by the falling remains of the rocket.

Construction

Exclusion zones are commonly used in the construction industry worldwide. For this purpose they are defined locations to prohibit the entry of personnel into danger areas, established through the risk assessment process for a construction activity. Typically, exclusion zones are set up and maintained around plant and below work at height.

Protesting

With regard to protesting, an exclusion zone is an area that protesters are legally prohibited from protesting in.

Exclusion zones often exist aroundseats of governmentandabortion clinics.As a result of protests by theWestboro Baptist Churchat the funerals of soldiers killed in theIraq War,29 states and the US Congress created exclusion zones around soldiers' funerals.In 2005, theParliament of the United Kingdomcreated a one kilometre exclusion zone around itself.

TheFirst Amendment to the United States Constitutionstates that "Congress shall make no law... abridging... the right of the people peaceably to assemble, and to petition the Government for a redress of grievances." The existence of exclusion zones is based on court rulings that allow the government to regulate the time, place, and manner of protests.

An exclusion zone is related to afree speech zone.Protesters are required to picket in a free speech zone, thus rendering the area around the free speech zone to be an exclusion zone.

Restraining orders

When arestraining orderis issued, an exclusion zone is an area that the respondent is prohibited from entering—often an area surrounding the petitioner's home or workplace. For example, if aWisconsinharassment restraining orderordomestic abuse restraining orderis violated, the court may orderGPSmonitoring of the respondent.If the exclusion zone is breached, the GPS technology notifies law enforcement and the petitioner.
