Can intermediate storage tanks for Class A and B liquids be installed inside the factory building?

I’m also looking for an answer. Could that kind person help?

It can be set, just make sure the amount doesn’t exceed what can be used in one day and night!

3.3.9 When Class A and Class B intermediate warehouses are installed within a factory, their storage volume should not exceed the amount required for one day and one night. The intermediate warehouse should be located against the exterior wall, and it should be separated from other areas by fire walls and non-combustible floor slabs with a fire resistance rating of not less than 1.50 hours. Specific explanation: This article contains specific provisions regarding intermediate warehouses within factory buildings that store Class A and Class B items. To meet the daily production needs of the factory, it is often necessary to obtain a certain amount of raw materials, semi-finished products, and auxiliary materials from the warehouse or from previous processing stages’ factories (or workshops) and store them within the factory. The place where the aforementioned items are stored is called an intermediate warehouse. If flammable and explosive items of categories A and B are not stored separately and isolated from each other, they will affect one another in the event of a fire, resulting in greater losses. This provision stipulates that the inventory in the intermediate warehouse should be kept at a level sufficient for one day and one night of usage. However, due to differences in factory size and products, the absolute amount required per day varies, making it difficult to establish a specific limit value. For some factories with lower consumption needs, such as watch factories that use gasoline for cleaning and require only 20 kg per day and night, the amount stored for 1–2 days and nights can be adjusted accordingly ； If a larger amount is required per day and night, it should be strictly controlled to the amount needed for one day and night. In addition, this clause also specifies the layout and partitioning requirements for intermediate warehouses; where possible, such warehouses should be equipped with exits leading directly to the outside.

Reply to the person on floor 4: Version 3.3.9 specifies requirements for setting up warehouses in workshops, but it does not provide any guidelines regarding the installation of storage tanks in workshops. My understanding is that since the volume of Class C liquid storage tanks that can be installed in workshops must be less than 1 cubic meter, it should be prohibited to have Class A or B intermediate storage tanks in workshops, as such tanks can easily be placed outside the workshop and then pumped into it.

Well, in terms of production, the equipment should be designed to meet the requirements of the manufacturing process. Based on my experience in various industries and my evaluations, storage tanks of types A and B are necessary in such facilities. This warehouse can also be considered a type of tank. The building design fire codes provide relatively little information specific to the chemical industry; they refer to general principles, so it’s not necessary to take them too literally. For more detailed information, one should refer to the oil industry regulations.

I agree with what the student from the sixth floor said. Although the specifications do not specify it explicitly, Class A and Class B storage tanks should still be avoided in workshops. Unless it is closely linked to the manufacturing process, it must be placed in the workshop. Such as sump tanks, etc.

Intermediate storage tanks should not be allowed, but metering tanks are permissible, with size restrictions as well

Agree with what was said on floor 6. If Class C is available and the volume doesn’t need to exceed 1 liter, then it’s difficult to implement Classes A and B.

Given that Class A and B liquids are volatile and tend to accumulate in workshops, and that accidents can cause significant damage to equipment and other items, it is best not to store them in workshops. 6# taizhong

It is only feasible if the reserves do not exceed the amount needed for one day and one night! If you say it does not meet the standards, then imagine that in order to address this issue (or make the necessary corrections), a mixing device can be installed on this intermediate storage tank!

No relevant specifications were found, but this situation seems to be common – things like measuring tanks in workshops, for example. In my opinion, Class A and Class B warehouses can also be considered as Class A and Class B tanks, but it is necessary to control the appropriate amounts

It can be set, but the usage cannot exceed that of one shift

I’m still studying it, but as far as I understand it, I agree with the main point from the 6th floor: it’s best not to store it, mainly due to quantity issues

Agree with the opinion on floor 6, but a metering tank can be placed at a higher position

It is generally placed outside the workshop as a utility tank and is not inspected as a storage tank.

It can be set, but the usage cannot exceed 24 hours.
