There are various issues regarding the classification of production processes that pose fire hazards within factory buildings
Thread Content
I have a question: Article 3.1.2 of the Building Code specifies rules for determining the fire classification of a building or a fire compartment when there are operations with different fire hazards within the same building or fire compartment. It states that if the area occupied by the part with the higher fire hazard is less than 5%, the fire classification can be determined based on the lower fire hazard. Here’s a question: how is the area for this production section defined? Is it the area occupied by the device itself, or the area including a certain surrounding area around the device? For example, in the case of two Class A reaction vessels with a clear distance of 1.5 meters between them, is the space covered by these 1.5 meters taken into account? How much of the pot’s perimeter needs to be included?
Looking forward to an explanation from the design institute or the fire department.
When the amount of flammable or combustible materials used or generated during the production process is small enough as not to pose a risk of explosion or fire, it can be determined based on the actual circumstances； When one of the following conditions is met, it can be classified based on the part with a lower fire hazard: If these two Class A reaction vessels pose a sufficient risk of explosion, they should be classified as Class A directly.
Thank you! But how should the 5% in the standards be understood?
Landlords should note that to reduce the fire hazard category of a room, it is not sufficient to consider only the proportion of floor area occupied by the equipment with the highest fire hazard category. In addition to having a floor area that is below the standard requirements, it must also meet the condition that \"in the event of an accident, the fire cannot spread to other areas, or fire prevention measures can be used to prevent the spread of the fire\", such as the installation of firewalls. Only when both the area requirement and the corresponding preventive measures are satisfied can the equipment be classified as belonging to a lower fire hazard category.
Thanks to the person above! Does that mean it is calculated based on the area inside the firewall?
