There are actually unreasonable aspects in Table 4.2.2 and Note 6 of the building code; for example, if I have two Class C above-ground storage tanks with a flash point of 70°C and a diameter of 3m each, then the distance between them should be 1.2m. Similarly, there are two Class C above-ground storage tanks with a flash point of 130°C and a diameter of 3 m each; according to Note 6, the fire separation distance must be at least 2 m ； Logically, the higher the flash point, the lower the fire risk, but the fire separation distance increases. That’s not reasonable
{:3_60:} Personally, I think there’s no need to strictly follow the rules; it’s better to consider the actual situation. Generally, Class C storage tanks are large in size; 0.4D is sufficient ； If requirements such as evacuation are met, 2m isn’t necessarily essential. Otherwise, it would be a hassle for companies with small premises.
If there are two conflicting requirements, just apply a stricter standard; our requirement is that it be no less than 2m. PS: Generally, tanks with a diameter of less than 3 meters are rarely placed in tank areas; instead, they are kept in the workshop and used as supporting containers.
I have a question: if it’s used as a container in a workshop, then no cofferdam is needed, right? Only applicable to storage tanks less than 3 meters?
Strictly speaking, the specification is indeed not precise here.
It doesn’t have to be less than 3 meters; in my workshop, I’ve used tanks with a diameter of up to 4 meters. A retaining structure is used to prevent leaks from spreading throughout the entire workshop.
Oh, this arrangement works too. I’ve never seen a tank area set up in a workshop before. With a retaining wall added, might it look strange?
It’s not really considered a tank farm either; it’s just a few individual storage tanks, three or four in total. We call them intermediate product tanks or temporary storage tanks, and they can be regarded as equipment used in the workshop.
A intermediate tank is definitely feasible, but a proper raw material tank area probably won’t work.
Yes, so you need to work on the name by avoiding certain sensitive terms
It’s like trying to steal thunder by covering one’s ears – our landlord wanted to do the same, but I refused firmly. It should be as it is; I definitely won’t be a victim of unfair treatment{:3_48:}
