My company has sold a steel building to be used as an aircraft hangar. The building is 22,500 square feet (150 x 150) and
is for airplane storage only. The access door height is 28' or less. The building has a single fire area. My interpretation
of NFPA requirements seems to indicate that a fire protection system would not be required. There are no hazardous
operations in this building such as fuel transfer, welding, painting, torch cutting, etc.
Am I correct to assume that this is a Group III Hangar, Type 1 and a fire protection system is not required
