What type of building falls under risk category IV?

Risk category IV pertains to buildings and structures essential for emergency response and disaster recovery, which must remain operational during significant disasters or catastrophic events. Fire and rescue stations are integral for maintaining public safety and disaster response capabilities. Therefore, they are classified as risk category IV structures due to their critical role in community safety and their necessity to be functional in emergency situations.

In contrast, single-family homes, parks and recreational facilities, and museums serve different purposes and are not considered essential infrastructure in times of emergency. Single-family homes provide residential shelter but are not crucial for disaster response. Parks and recreational facilities offer community services but do not play a vital role in emergency management. Museums, while important for cultural preservation and education, also do not have the same level of operational demand during emergencies as fire and rescue stations. This distinction underscores why fire and rescue stations are placed in risk category IV.
