4. PREPARATION FOR WORK AND CHECK THE TECHNICAL CONDITION OF THE WATER FIRE EXTINGUISHING INSTALLATION

4.1. Water fire extinguishing installation consists of:

Source of water supply (reservoir, pond, city water supply, etc.);
- fire pumps (designed for the intake and supply of water to pressure pipelines);
- suction pipelines (connecting the water source with fire pumps);
- pressure pipelines (from the pump to the control unit);
- distribution pipelines (laid within the protected premises);
- control units installed at the end of pressure pipelines;
- sprinklers.

In addition to the above, based on the design solutions, the scheme of fire extinguishing installations can include:

Water tank for filling fire pumps;
- pneumatic tank to maintain constant pressure in the network of the fire extinguishing installation;
- compressor for feeding the pneumatic tank with air;
- drain cocks;
- check valves;
- dosing washers;
- pressure switch;
- manometers;
- vacuum gauges;
- level gauges for level measurement in tanks and pneumatic tank;
- other signaling, control and automation devices.

The schematic diagram of the water fire extinguishing installation is shown in the figure.

4.2. After completion of installation work, suction, pressure and distribution pipelines must be flushed and subjected to hydraulic tests. The results of flushing and pressure testing must be documented in acts (Appendices 1 and 2).

If possible, the effectiveness of the fire extinguishing installation should be checked by organizing the extinguishing of an artificial fire source (Appendix 3).

4.3. When flushing pipelines, water should be supplied from their ends towards control units (in order to prevent clogging of pipes with a smaller diameter) at a speed of 15-20% more than the speed of water during a fire (determined by calculation or recommendations of design organizations). Flushing should be continued until a stable appearance of clean water.

If it is impossible to flush individual sections of pipelines, it is allowed to purge them with dry, clean, compressed air or inert gas.

4.4. Hydraulic testing of pipelines must be carried out under a pressure equal to 1.25 working (P), but not less than P + 0.3 MPa, for 10 minutes.

To isolate the test section from the rest of the network, blind flanges or plugs must be installed. 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 there are no signs of rupture, leakage and drops in the welded joints and on the base metal, visible residual deformations.

The pressure should be measured with two manometers.

4.5. Flushing and hydraulic testing of pipelines must be carried out under conditions that exclude their freezing.

It is forbidden to backfill open trenches with pipelines that have been exposed to severe frosts, or to backfill such trenches with frozen soil.
