Code for design of fire extinguisher configuration in buildings

Specification for Fire Extinguishers in Buildings is a book published by China Planning Press in 2005 and edited by People's Republic of China (PRC) and the Ministry of Public Security. In the process of compiling this specification, with reference to similar specifications at home and abroad, in-depth investigation and study, communication with scientific research, design, construction and users for many times, active absorption of mature experience in the design and application of building firearms engineering at home and abroad, combined with the current engineering practice in China, after repeated discussion and careful revision, it was finally finalized by the relevant departments.
