Which areas in shelters not protected by a sprinkler system should not be used?

Gathering places in shelters that are not protected by a sprinkler system should not be used primarily because these areas typically serve as high-occupancy locations where large numbers of individuals congregate. In the event of a fire, these spaces can become quickly hazardous due to the potential for rapid smoke buildup and heat conduction. The lack of a sprinkler system means there is no active fire suppression, increasing the risk to occupants who may have difficulty evacuating safely under such conditions.

While other areas such as kitchens and storage rooms also present risks, especially regarding fire sources, the gathering place specifically involves a larger number of people who may be at risk during an emergency. The goal is to ensure that the highest level of safety is maintained, which is why avoiding large gathering areas in unsprinklered sections is crucial for fire safety protocols within the shelter environment.
