INDIA UPDATES AGAINST COVID-19 DETECTS BY REAL TIME RT-PCR|CORONAVIRUS UPDATES|JAI HIND JAI BHARAT
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. The focus for preventive actions is to avoid dangers and risks arising from the nonconformances to the normal circumstances, but also commonly includes improvements in efficiency.

Preventive lockdowns are preemptive lockdowns to mitigate risk. Most organisations plan for the emergency lockdowns but fail to plan for other situations which might quickly degrade to dangerous levels. These protocols must be based on the type of threat, and should be kept simple and short for quick learning and implementation, and flexible enough to handle several scenarios. This allows administrators more options to choose from which are easier to use in various scenarios. For example, in case of a loud scene by a parent or an unarmed petty thief being chased by the police through the school playground, this flexible procedure allows school administrators the flexibility to implement a more limited lockdown while teaching in school continues, this eliminating need for complete emergency lockdown, disruption and delays in resumption of teaching, etc. The consequences of not having procedures to implement such lockdowns is that the situation might quickly escalate where there could be loss of human lives.[1]

Emergency lockdown

Emergency lockdowns are implemented when there is imminent threat to the lives or risk of injury to humans, for example, a school's emergency lockdown procedures must be kept short and simple to make them easier to use under real life crisis conditions. Simple procedures can be easily taught with periodic lockdown drills instead of lengthy training.[1]

Lockdowns can limit movements or activities in a community while allowing most organizations to function normally, or limit movements or activities such that only organizations supplying basic needs and services can function normally.[2]

COVID-19 pandemic
During the 2019–20 coronavirus pandemic, the term lockdown was used for actions related to mass quarantines.[3] By early April 2020, 3.9 billion people worldwide were under some form of lockdown—more than half the world's population.[4][5] By late April, around 300 million people were under lockdown in nations of Europe, while around 200 million people were under lockdown in Latin America.[6] Nearly 300 million people, or about 90 per cent of the population, were under some form of lockdown in the United States,[7] and 1.3 billion people have been under lockdown in India.[8]

Typical scenarios
Schools
Lockdown procedures vary by school district. Generally, a lockdown means that interior and exterior doors are locked, and all students and staff must remain in their location from the time the lockdown is announced. Windows are covered, and students stand at the back of the classroom or away from windows.

Since the Columbine Shooting in 1999, lockdown procedures in schools have been constantly changing. Some schools direct teachers to continue with standard procedures while remaining quiet, while some recommend an active approach against threats.[9]

Prisons
In its most common usage in corrections units, the term lockdown can be defined as a course of action to control the movement of inmates. Confining all prisoners, except workers, to their cells until the end of the day is an example of a "lockdown period" in a corrections schedule.[citation needed] However a "full lockdown" is used when all prisoners are locked in their cells to prevent prison riots or unrest from spreading or during an emergency.[10]

Hospitals
In US guidelines, occasions for preventing entry into a hospital may include: power failure, earthquake, flooding, fire, bomb threat, hostage crisis and active shooter.[11][12] Occasions for preventing both entry and exit from a hospital may include: external contamination, civil disturbance and abduction of an infant or child.[11][12]
