Fire protection facilities for Class A and B liquid storage tanks

According to clause 8.7.1 of the Petrochemical Fire Protection Code: Low-expansion foam fire suppression systems should be used in areas where fires involving flammable liquids may occur. Since the standard specifies \"it is advisable\", can I then choose not to install a foam fire extinguishing system and opt only for a cooling water system?
What you’re saying is too general; whether to install a low-expansion foam fire suppression system should be determined based on the properties of the materials stored in Class A and B tanks. “\"Yi\" is a term indicating that something should be done first when the conditions permit; if such conditions exist, why not do it? It’s better to use it than not to use it at all. Of course, if you don’t have this condition, you can choose not to use it. This is my understanding, for reference only.
Foam fire suppression systems should be installed in storage tanks for Class A and B liquids.
Could you specify on the upper floor which regulation states that it should be installed?
A foam fire suppression system should be installed, especially for Class A areas
All oil tanks are equipped with foam fire suppression systems, unless they are single, very small tanks
However, LPG storage tanks are not equipped with foam fire suppression systems; only water-based fire suppression systems are used
For vertical Class A medium-volume oil tanks, aside from those where regulations require the installation of a fixed foam fire extinguishing system, it is recommended that smaller tanks be equipped with a semi-fixed system to prevent helplessness in the event of an internal fire
This problem is easy to solve. According to the specifications, it is specified whether fixed or semi-fixed foam should be used for tanks of a certain size. But in most cases, we use foam when constructing tanks, unless they are too small. When you do it, you should also refer to the oil depot specifications; there are differences between the two.
LPG is liquefied petroleum gas; it refers to spherical tanks, pressure vessels – how could it be used to make foam? You probably understand the principle of a foam generator. Ah, read more books; don’t mislead children here
