If possible, the effectiveness of the fire extinguishing installation should be checked by organizing extinguishing an artificial source of fire.
When flushing pipelines, water should be supplied from their ends towards the control units (in order to prevent clogging of pipes with a smaller diameter) at a speed 15-20% higher than the speed of the solution in case of fire (determined by calculations or recommendations of design organizations). Flushing should be continued until a steady appearance clean water. If it is impossible to flush certain sections of pipelines, it is allowed to blow them with dry, clean, compressed air or inert gas.
Hydraulic testing of pipelines must be carried out under a pressure equal to 1.25 working pressure (P), but not less than P+0.3 MPa, for 10 minutes.
To disconnect the tested section from the rest of the network, it is necessary to install blind flanges or plugs. It is not allowed to use existing control units, repair valves, etc. for this purpose.
After 10 minutes of testing, the pressure should be gradually reduced to working pressure and a thorough inspection of all welded joints and adjacent areas should be carried out.
The pipeline network is considered to have passed the hydraulic test if no signs of rupture, leakage or drops are found in welded joints and on the base metal, visible residual deformations.
Pressure should be measured with two pressure gauges.
Flushing and hydraulic testing of pipelines must be carried out under conditions that prevent them from freezing.
It is prohibited to fill open trenches with pipelines that have been exposed to severe frosts, or to fill such trenches with frozen soil.

1. INTRODUCTION
1.1. Air-mechanical foam is the most effective fire extinguishing agent for extinguishing class A fires (combustion solids) and B (combustion of liquid substances).
1.2. To obtain air-mechanical foam, foam concentrates and fire fighting equipment are used. Depending on the area of application, foam concentrates are divided into two classification groups: general purpose and special purpose. To foam concentrates general purpose include: PO-3NP, PO-3AI TEAS. Foaming agents for special purposes include: “Sampo”, “Morskoy”, “Potok”, “Film-forming”, “Foretol”, “Universal”, POF-9M.
Special purpose foam concentrates differ from general purpose foam concentrates in their higher fire extinguishing ability due to the use of recycled additives.
All foaming agents for general and special purposes do not lose their original physical and chemical properties during repeated freezing and subsequent gradual thawing.
Energy plants mainly use general purpose foaming agents.
1.3. To extinguish fires at transformers and reactors, low-expansion air-mechanical foam is used, and at fuel oil and oil industries, medium-expansion foam is used.
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;
PO - foaming agent;
PI - fire detector;
OK - check valve;
Control room - block control panel.

EXTRACT FROM THE WORK “ORDER OF APPLICATION, TRANSPORTATION, STORAGE AND QUALITY CHECKS OF FOAMING AGENTS FOR FIRE FIGHTING. (INSTRUCTIONS)"
TESTING METHODS FOR FOAMING AGENTS
1 . DETERMINING APPEARANCE
1.1. Appearance The foaming agent is determined visually in a test tube made of colorless glass P2 with a diameter of 30 mm and a capacity of 250 cm 3 (GOST 253336-82) in transmitted scattered light.
1.2. To determine the crystalline precipitate, a foaming agent pre-filtered at 20 ° C is poured in an amount of 250 cm 3 into a cylinder with a capacity of 250 - 500 cm 3 and placed in a refrigerator at a temperature of (3 + 2) ° C. After 24 hours of exposure there should be no formation of crystalline sediment visible to the naked eye.
2 . DETERMINATION OF PORNING TEMPERATURE
2.1 . Equipment
Test tube P2T-250 TS according to GOST 25336-82;
test tube P1-16-150 HS according to GOST 25336-82;
mercury thermometer type TN-6 according to GOST 400-80;
vessel with a cooling mixture.
2.2 . Carrying out tests
A clean, dry glass tube with a diameter of 16 mm is filled with foaming agent to a height of 30 mm. The test tube is closed with a stopper with a thermometer inserted into it and placed in a test tube with a diameter of 30 mm so that the walls of the test tube are at the same distance from the walls of the coupling.
The assembled device is placed in a vessel with a cooling mixture, the temperature of which should be 5 °C below the expected freezing temperature of the foam concentrate.
The pour point is taken to be the value established after the decline and rise.
2.3 . Processing the results
Determination of the pour point is carried out 3 - 4 times. The final result is the arithmetic mean of all determinations.
3 . DETERMINATION OF FOAM EXPANSION AND STABILITY IN LABORATORY CONDITIONS
3.1 . Equipment, reagents
Device “Tissue Shredder” (RT-1) according to TU 64-1-1505-79. A graduation must be applied to the instrument glass with a division value of 50 cm 3 to the final value of 1000 cm 3.
Cylinder 2-100 according to GOST 1770-74.
Stopwatch according to GOST 5072-79, accuracy class 3.
Distilled water according to GOST 6709-72.
3.2 . Carrying out tests
The foaming agent in the amount necessary to obtain a concentration solution is poured into the cylinder and adjusted with distilled water to 100 cm 3 . The resulting foaming agent solution at a temperature of (18 + 1) °C is poured into the glass of the device, the speed switch is set to 4000 rpm, then the electric motor and stopwatch are turned on simultaneously. The solution is stirred for 30 s, the electric motor is turned off and the volume of the resulting foam in the glass is recorded.
The foam multiplicity 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 for 50% (50 cm3) of the foaming agent solution to be released from it.
The arithmetic mean of three determinations of the foam ratio is taken as the test result.
3.3 . Determination of foam stability on the surface of ethyl alcohol
3.3.1 . Instruments and reagents used

Mechanical stopwatch according to GOST 5072-79, class 2, measurement limit 60 min.
Rectified ethyl alcohol according to GOST 5962-67 or technical alcohol according to GOST 18300-87.
3.3.2 . Carrying out tests
Measure 100 ml of ethyl alcohol with a cylinder and place it in a glass, which is placed on a scale. 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. In the event of the formation or destruction of foam in the process of open areas of the surface of the alcohol or peeling of the foam when large air bubbles form, it should be leveled with a glass rod foam over the entire surface of the alcohol, without touching the separating gel-like film.
A stopwatch records the time from the moment the first portion of foam is applied to the alcohol until open areas of the surface of the alcohol or separating film appear. This time determines the stability of the foam on the surface of the alcohol. The test is carried out three times. The arithmetic mean is taken as the final result.
