│Note: │
│A.The foam outlets of different types are defined as follows│
│ : │
│(1) Type I foam outlet: refers to an outlet through which │
│ foam is injected from the upper part of a fixed-top │
│ storage tank. It is located at the upper part of the │
│ side plate of the storage tank, and is provided with │
│ foam conduit or slide away and other auxiliary devices, │
│ which prevent the foam from submerging into the liquid │
│ or agitating the liquid, and enable the foam to extin- │
│ guish the fire effectively. In addition, a device is │
│ provided to prevent the adverse flow of the public │
│ hazardous materials inside the storage tank. │
│(2) Type II foam outlet: refers to an outlet through which │
│ foam is injected from a fixed top or the upper part of a│
│ storage tank. The outlet is attached with a foam reflec-│
│ ting plate, which makes the discharged foam flow along │
│ the inner side of the side plate, prevents the foam from│
│ submerging into the liquid or agitating the liquid, and │
│ enables the foam to extinguish the fire effectively. In │
│ addition, a device is provided to prevent the back flow │
│ of the public hazardous materials inside the storage │
│ tank. │
│(3) Special type foam outlet: refers to an outlet through │
│ which foam is injected from the upper part of the outer │
│ floating top of a storage tank. The outlet is attached │
│ with a foam reflecting plate, which enables the foam to │
│ be injected into the loop formed by the side plate of │
│ storage tank and the foam separator plate. The separator│
│ plate is a steel plate installed more than 0.3m │
│ (inclusive) above the floating top and more than 0.3m │
│ (inclusive) away from the inner side of the storage tank│
│ , and it is provided with a device to prevent the foam │
│ from flowing out and discharge the water effectively │
│ depending on the expected maximum rainfall in the area │
│ where the storage tank is set. │
│(4) Type III foam outlet: refers to an outlet through which │
│ foam is injected from the bottom of a fixed-top storage │
│ tank. A foam transmission pipe (designed with a struc- │
│ ture or mechanism which can prevent the public hazardous│
│ materials inside the storage tank from flowing adversely│
│ through the pipe) is provided to transmit the foam gene-│
│ rated by the foam generator into the storage tank, and │
│ discharge the foam through the outlet. │
│(5) Type IV foam outlet: refers to an outlet through which │
│ foam is injected from the bottom of a fixed-top storage │
│ tank. The tail end of the foam transmission pipe is │
│ connected to the special hose stored in the storage │
│ cylinder (designed with a cover which is easy to break │
│ off when foam is injected) located on the bottom under │
