Firewall, blast wall, fire partition
Thread Content
I saw in other posts the differences between firewalls and blast walls; what are the differences between fire partitions and these two? Is a firewall the same as a fire barrier?
Firewalls only have requirements regarding fire resistance duration; ordinary brick walls generally also possess a fire resistance capacity of 1.5 to 2 hours. Different wall materials can be chosen depending on the technical requirements； Explosion-resistant walls are designed by calculating the force of the explosion based on its distance, and then determining the appropriate specifications for such walls; these walls are always made of reinforced concrete.
A firewall is not the same as a fire barrier. Firewalls are required to have a fire resistance rating of three hours, while fire partitions only need to meet fire resistance standards without any specific time limit.
In 3.3.7, it is stated that the room for the intermediate storage tank should be separated from other areas by fire partitions with a fire resistance rating of not less than 3.00 hours, as well as floors with a fire resistance rating of 1.50 hours. In my opinion, the fire resistance rating of these fire partitions need not be lower than that of regular fire walls; it’s just that there are differences in terms of structure and construction It is not possible to determine whether it is a firewall or a fire partition based on the fire resistance rating
The two are different; blast walls are primarily designed for providing protection against explosions. Of course, a certain fire protection rating is also required, and a firewall is only involved in fire prevention.
If I remember correctly, the partition wall is supposed to be 2.5
