The factory building is 100 square meters in size, and there is a small room of 20 square meters where hydrogen is produced

The factory has an area of 100 square meters, with a small room of 20 square meters where hydrogen is produced. If this room is separated from the other areas using firewalls, then: 1. Is it sufficient to ensure explosion protection only within those 20 square meters, while explosion protection is not required in the areas outside the firewalls? ? Is there a legal basis for this? 2. Is it not necessary to classify the entire factory building as Category A? Can the fire hazard level of the factory building be reduced? ? ? Is it only 20 square meters that are classified as Category A? ? ?

1. The production of hydrogen constitutes a hazardous chemical construction project. 2. For construction projects with explosion risks, the fire separation distances must meet the requirements of GB50160 at a minimum. 3. In accordance with petrochemical regulations, the entire plant should be classified as a Class A workshop.
Neither the provisions of the Building Code \"GB 50016-2014 Code for Fire Protection Design of Buildings\" nor those of the Petrochemical Code \"GB 50160-2008 Code for Fire Protection Design of Petrochemical Enterprises\" permit it. For your reference, according to GB 50160-2008 Code for Fire Protection Design of Petrochemical Enterprises, 3.0.5 states that the fire hazard classification of a room should be determined based on the fire hazard classification of the equipment located within that room. When equipment with different fire hazard classifications is installed in the same room, the fire hazard classification of the room shall be determined based on the equipment with the highest fire hazard classification among them. However, when the proportion of equipment with the highest fire hazard category accounts for less than 5%, and in the event of an accident, it is not sufficient to spread to other areas or fire prevention measures can prevent the spread of fire, it may be classified according to the equipment with a lower fire hazard category.
