INTRODUCTION 1.1. Air-mechanical foam is the most effective fire-extinguishing agent for extinguishing fires of classes A (combustion of solid substances) and B (combustion of liquid substances). 1.2. To obtain air-mechanical foam, foam concentrates and fire fighting equipment are used. Depending on the field of application, foam concentrates are divided into two classification groups: general and special purpose. To foam concentrates general purpose include: PO-3NP, PO-3AI TEAS. Targeted foam concentrates include: "Sampo", "Marine", "Potok", "Film-forming", "Foretol", "Universal", POF-9M. Special purpose foam concentrates differ from general purpose foam concentrates in their higher fire-extinguishing capacity due to the use of secondary additives. All foam concentrates of general and special purpose do not lose their original physical and chemical properties during repeated freezing and subsequent gradual thawing. In power plants, general-purpose foam concentrates are mainly used. 1.3. To extinguish fires at transformers and reactors, air-mechanical low expansion foam is used, at fuel oil and oil facilities - medium expansion foam. Low-expansion foam is obtained using OPDR foam sprinklers and its modifications. NKR - concentrated solution pump; OPDR - rosette foam deluge sprinkler; GPS - medium expansion foam generator; GPSS - stationary medium expansion foam generator; Main control room - main control panel; PU - control panel; KR - concentrated solution; ON - foaming agent; PI - fire detector; OK - check valve; Main control room - block control panel. 2. GENERAL PROVISIONS 2.1. This Instruction is the main technical document used to develop local instructions for the operation of specific fire extinguishing installations with air-mechanical foam installed at power enterprises. 2.2. The local operating instructions for a specific fire extinguishing installation with air-mechanical foam are developed by the organization that commissioned this installation, together with the power company where it is used. If the adjustment was carried out by a power company, then the instruction is developed by the personnel of this enterprise. 2.3. When developing local instructions, in addition to this Instruction, it is necessary to take into account the requirements of design and technical documentation for equipment, instruments and apparatus that are part of the fire extinguishing installation. 2.4. The local instructions should include the relevant labor protection requirements and environmental protection measures that ensure the safety of operation, technical supervision and repair work on a specific fire extinguishing installation for personnel. 2.5. The local instruction must be reviewed at least once every three years and every time after the reconstruction of the foam fire extinguishing installation or in the event of a change in operating conditions. 3. SAFETY MEASURES DURING AUPP OPERATION 3.1. All rotating parts of PPT, NKR pumps must be protected by protective covers. It is forbidden to clean and wipe the pumps during their operation. 3.2.

When a concentrated foaming agent arrives at a power plant, it is necessary to make sure that there is a document certifying its quality and quantity. After that, a tank filling scheme is prepared and the pump for pumping concentrated foam concentrate is turned on. At the end of the pumping of the foaming agent, the original recirculation scheme is restored. 5.3. Before refueling AUPP, it is necessary to check the quality of the foam concentrate or its ready-made solution according to the method given in the work “Procedure for the use, transportation, storage and quality control of foam concentrates for extinguishing fires. (Instruction)". Moscow: VNIIPO MVD USSR, 1989). Analysis of the foaming agent solution is carried out in the laboratory of the power company. In the future, the quality of the foam concentrate or its aqueous solution in the AUPP should be checked once every six months. If the ratio of the foam obtained in the laboratory is less than 5 or its stability is less than 3 minutes, replace the foaming agent and its aqueous solution. An unsuitable foaming agent solution according to the appropriate scheme can be supplied through steam-mechanical fuel oil nozzles to the furnaces of operating boilers for combustion, or disposed of in another way that does not contradict environmental requirements. 5.4. After the activation of the AUPP, further use of the foaming agent or its aqueous solution is allowed, depending on the amount of residue and its quality. It is not allowed to mix the remaining foaming agent or its aqueous solution with other brands of foaming agent. Before filling the container with a new foaming agent, it is necessary to check its quality if it has not been checked for more than 3 months. 5.5.

The solution is stirred for 30 s, the electric motor is turned off and the volume of the resulting foam in the beaker is recorded. The foam ratio is calculated as the ratio of the resulting volume (in cm 3) of foam to 100 cm 3 of the solution taken for testing. The stability of the foam is determined by the time it takes to release 50% (50 cm 3) of the foam concentrate solution from it. The test result is taken as the arithmetic mean of three foam ratio determinations. 3.3 . Determination of foam stability on the surface of ethyl alcohol 3.3.1 .

Testing 100 ml of ethyl alcohol are measured with a cylinder and placed in a beaker, which is placed on a balance. Foam (obtained in accordance with the requirements of clause 6.2) is applied to the surface of the alcohol in an amount of (8 + 0.5) g. foam over the entire surface of the alcohol without touching the release gel film. The stopwatch fixes the time from the moment the first portion of the foam is applied to the alcohol until the appearance of open areas on the surface of the alcohol or the separating film. This time determines the stability of the foam on the alcohol surface. The test is carried out three times. The arithmetic mean is taken as the final result. 4 .
