Hydrogen peroxide is used on site, and I plan to purchase barrels of it; the daily usage is only 500 KG. Are there any fire separation requirements that need to be met in this case? The factory building was originally a regular one – can it be placed inside it? Is a fire dike needed?
Ordinary factory buildings won’t do; hydrogen peroxide falls under Class A in terms of fire resistance requirements. If it is stored for more than a day or night, the facility needs to be designed as a warehouse. It’s advisable to refer to the design fire protection codes for petrochemical enterprises, as these codes are currently enforced quite strictly
Check what category your ordinary factory building falls into; it must meet the requirements regarding warehouse regulations and fire separation distances, otherwise there will definitely be problems if an inspection is conducted
In my personal opinion, hydrogen peroxide should be classified as Category A. It’s necessary to check whether the amount used exceeds the allowed limits according to building codes; if it can be downgraded, it should be classified as Category B. It shouldn’t be stored in ordinary factories, and the fire separation distances should be determined based on the fire hazard category
According to Article 3.3.6 of the building codes, it does not specify whether intermediate warehouses of Class A are intended for use in ordinary factories or in factories of Classes A and B. How should this be interpreted? Can an intermediate warehouse also be placed in a regular factory building?
Recently, during design discussions with the design institute, they said that if Class A liquids are stored for more than a day and night, a separate warehouse must be built. However, this can be avoided in practice; you can claim that the storage duration will be only 20 hours
May a intermediate warehouse for Class A liquids be located in a regular factory building, that is, a building that is not classified as Class A, B, or C?
You’re using a ton barrel; you can place the barrel further away. If the inspection fails, you can place it even further away. . . . Then a small pump can be used to feed the material, which is also easy.
For weights over 20 KG, a separate storage area is required; this storage area must be separated from the rest of the factory building by partitions with a fire resistance rating of at least level 2. As for whether the large factory building needs to have its category upgraded, it depends on the area of the separate compartments – if they account for more than 5% of the total area of the factory building, then its category needs to be upgraded; if it’s less than 5%, it can remain in its current category. The production category of hydrogen peroxide is related to its concentration; it seems that those with a concentration of over 30% fall into Category A, while those with a concentration below 30% fall into Category B. I’m not quite sure about the details
If your large factory building is not classified as Category A, B, or C, its architectural design must comply with relevant construction regulations. The fire separation distance refers to the distance between your large factory building and surrounding structures. If the entire facility is subject to petrochemical industry regulations, it is advisable not to upgrade the classification of your factory building. This is because changes in the fire compartments within the building or in the fire resistance rating of the structures may require modifications; however, if there isn’t enough distance between your factory building and neighboring buildings, such modifications become impossible.
Excuse me, sir: Is it a regulation that items weighing over 20 KG need to be stored in a separate storage area? Where does this rule come from?
