What is a warm zone defined as in an active shooter scenario?

In the context of an active shooter scenario, a warm zone is precisely defined as an area that lies outside of the hot zone, which is where immediate danger is present. The warm zone may have potential threats, meaning that while it is not under active fire, caution must still be exercised. This area allows for some level of tactical response and access by law enforcement and emergency personnel, enabling them to prepare for rescue operations or evacuate individuals in a controlled manner while acknowledging that risks still exist.

In contrast, areas defined as hot zones would indicate where active threats are ongoing, while safe zones are free from danger entirely and designated solely for recovery efforts. Restricted access areas for law enforcement are typically more secure perimeter locations that do not provide for an immediate tactical response or resourcing for those needing aid, diverging from the transitional nature associated with a warm zone during an active shooting situation.
