Foreword

4.1 , 4.2 and 4.3 of this standard are mandatory and the rest are recommended.

This standard was proposed by the Ministry of Public Security Fire Department.

This standard is under the jurisdiction of the Ninth Technical Committee of the National Fire Protection Standardization Technical Committee ( SAC/TC113/SC9 ).

This standard was drafted by the Ministry of Public Security Fire Department, the Shanghai Public Security Fire Corps, the Zhejiang Provincial Public Security Fire Corps, the Jiangsu Provincial Public Security Fire Brigade, and the Ministry of Public Security Tianjin Fire Research Institute.

The main drafters of this standard: Guo Tienan, Zhu Liping, Ma Heng, Li Shuhui, Shen Wen, Ji Junxian, Shen Youdi, Zhao Qingping, Feng Wangbi, Xiong Jun, Zhu Ming, Feng Wei, Song Shuxin, Tian Liang, Ni Zhaopeng, Wang Zongcun.

This standard is the first release.

introduction

In the existing factory buildings, warehouses, and shopping malls, staff dormitories are set up, or activities such as production, storage, and operations are carried out in residential and other civil buildings, while the accommodation and other sections have not taken necessary fire separation and fire protection facilities as required. This makes the fire safety conditions of such buildings incompatible with the nature of the construction and has a high fire risk. In order to implement the national fire prevention policies and policies, prevent and reduce fires, protect personal safety, and provide basis for the treatment of fire hazards, this standard is formulated.

Accommodation and production and storage operation place of fire safety technical requirements

range

This standard proposes the conditions for accommodation and production, storage, and management of common use sites (commonly known as “three in ones ” , hereinafter referred to as “combined sites” ), and specifies the fire separation measures, evacuation facilities, fire fighting facilities, and fires Source control and other fire safety technical requirements.

This standard applies to the fire safety management of existing accommodation and production, storage, and management of common use.
