Lockdown (in English),
general quarantine or prohibition of free movement of persons,
the closure of the economy and society is a temporary requirement for people to stay where they are (at home), usually because of specific risks for themselves or others (if they have been able to move freely until then). The term "stay home" is often used for locks that affect a specific area, rather than specific places. It is often associated with restrictions on public life in order to prevent an epidemic or pandemic.
During the ongoing covid-19 pandemic, large-scale closures were announced in individual countries.
The original meaning of the word lockdown is to lock prisoners in cells as a temporary security measure. The term is used for prison rules, which are usually intended to prevent people, information or objects from leaving the area. Rules can usually only be initiated by people in a position of authority.
Locks can also be used to protect people inside a device or, for example, in a computer system from a threat or other external event. In buildings, doors leading outwards are usually locked so that no one can enter or leave them. Complete locking usually means that people must stay where they are and must not enter or leave the building or the rooms in it, they must go to the nearest place marked as safe, if they are no longer there. Although there is no acute threat, practice locks can be held to familiarize people with what needs to be done during the lock.
Procedures must be planned for the use of both emergency and preventive locking.
Preventive locking is a preventive action plan implemented to address an unusual scenario or system weakness. It aims to prevent any danger, to ensure the safety of people, organizations and the system. Preventive measures focus on preventing hazards and risks arising from unusual circumstances, and usually also include improving efficiency.
Preventive locks are protective locks that reduce risk. Most organizations are planning an emergency shutdown, but do not plan to worsen the situation to dangerous levels. These plans must be based on the type of threat and should be simple and concise so that they can be easily learned and implemented; at the same time, they should be flexible enough to handle several scenarios. This allows administrators to choose from multiple options that are easier to use in different scenarios. For example, when the police chase an unarmed petty thief across school playgrounds, a more flexible approach allows school administrators to continue teaching; it is not necessary to proceed with a complete emergency blocking and disrupt teaching. If procedures are not in place to implement these exclusions, the situation could escalate quickly and lives could be lost.
Emergency locks are carried out when there is an imminent danger to life or injury to a person. For example, school emergency locking procedures must be short and simple to make them easier to use in real-life crisis conditions. Simple procedures can be easily learned with regular exercises instead of lengthy training.
Locking can restrict movement or activity in the community while allowing most organizations to function normally, or it can restrict movement or activity so that only organizations providing basic needs and services can function normally.
During the covid-19 pandemic, the term lockdown was used for actions related to mass quarantines or calls for people to stay at home. On
