│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 │
│ the liquid surface; when foam is injected, the special │
│ hose may be straightened to reach the front end of the │
│ special hose to the liquid surface, so as to discharge │
│ foam. │
│B.If a special type foam outlet is installed on a floating │
│ top, installation of a foam reflecting plate shall be │
│ exempted. │
│C.The Type III foam outlet in this table may be used only │
│ for the tanks processing or storing the public hazardous │
│ materials with a solubility of less than 1g in 100g of │
│ water under a temperature of 20℃ (hereinafter "non-water- │
│ soluble substances" for short) and storing the public │
│ hazardous materials with a temperature of less than 50 or │
│ with a dynamic viscosity of less than 100cst. │
│D.For the storage tank of inner floating top adopted with │
│ steel double deck or pantoon deck, the type and quantity │
│ of the foam outlets may be configured similarly as storage │
│ tank of outer floating top │
└──────────────────────────────┘
2. When storing water-insoluble Category IV public hazardous materials, the effective discharging volume from the foam outlets specified in paragraph 1 is, according to the following “public hazardous materials and types of foam outlet” table, calculated by multiplying the volume of foam solution outlet by the liquid surface of the storage tank and the discharge rate shall comply with the prescription specified on the table.
