This specification is compiled according to the requirements of the notice of the Ministry of Construction of the People's Republic of China on the issuance of the 1995-1996 National Standard Formulation and Revision Plan for Engineering Construction. Aircraft hangars are industrial buildings for aircraft maintenance. Modern aircraft are high-tech products, technology-intensive and expensive. In addition, because aircraft carry fuel, the fire hazard is high, so there are special requirements for fire protection engineering design. This specification is divided into nine chapters, including general provisions, fire protection zones and fire resistance levels, general layout and floor plan, building structure, safe evacuation, heating and ventilation, electrical fire protection, water supply and fire extinguishing equipment, etc. In view of the characteristics that the fire in the hangar is hydrocarbon fire and the aircraft is expensive, the hangar is divided into three categories according to the area of ​​the aircraft parking and maintenance area of ​​the hangar, and different fire extinguishing measures are taken accordingly.
