The Acquired Structures Program provides recruit, career, and volunteer firefighters with a realistic training atmosphere of an actual working residential fire environment while remaining a "real time" controlled training exercise. Loaned structures that are slated for demolition are acquired after they have met certain criteria and have been inspected for structural stability. Acquired structures include single family, multi-family, and commercial occupancies. The NFPA 1403 standard is always followed during any live burn training.
