Automatic volumetric fire extinguishing installations with an electrical part and designed to protect premises with people staying in them are allowed for commissioning if they include: devices for switching automatic start-up to manual with the issuance of a corresponding signal to the premises of the personnel on duty; sound and light fire alarms. A light warning signal in the form of an inscription on the light boards "Foam - go away" and an audible warning signal must be issued simultaneously within the protected premises. In this case, a light signal "Foam - do not enter" should appear at the entrance to the protected room, and in the room of the duty personnel - a corresponding signal with information about the supply extinguishing agent. Automatic fire extinguishing installations, the design of which provides for the presence of a duplicate manual start, must be operated in automatic mode. Devices for manual start-up of volumetric (except for local) fire extinguishing installations should be located outside the protected area near emergency exits with free access to them. Manual start devices for local fire extinguishing installations should be located outside the possible combustion zone at a safe distance from it. In this case, it should be possible to remotely switch on the unit outside the protected room. Maintenance of water and foam fire extinguishing installations The efficiency of installations depends on the quality of their operation, especially on the correct maintenance (MOT). Maintenance of water installations includes a number of activities carried out daily, weekly, monthly, once every 3 months, once every 6 months, annually, once every 3 years and once every 3.5 years. Daily maintenance includes the following operations: a) checking the cleanliness and order in the premises of the fire extinguishing station; b) control of the water level in the tank using control and measuring devices; c) external examination pulse device or pneumatic tank and control of the water level and air pressure (when the pressure drops by 0.05 MPa (0.5 kgf / cm "), air should be pumped); d) checking the voltage at the power supply inputs; e) external inspection of control units and control of pressure above and below valve (according to pressure gauges); f) control of access to control units and manual cranes, as well as control over the observance of the minimum distances from the sprinklers to the stored materials (which must be at least 0.9 m). Weekly maintenance includes all daily maintenance work and the following operations: a) control of pumps of fire extinguishing stations: starting pumps at 10, checking the serviceability of instrumentation (gearbox) and the tightness of fittings and connections, renewing the supply of lubricant in the lubricators, testing the compressor at idle, checking the automatic pump activation with switching the power supply from the working input to the reserve one ; b) check of control units (cleaning of taps with a small hole, check of operation of control units); c) checking the presence of spare sprinklers in the control cabinet: d) control of the pipeline system (inspection for the purpose of detecting and eliminating leaks, checking the condition of fasteners and painting of pipelines, tightness of stop valves, testing of manual valves); e) cleaning of sprinklers and stimulators from dust in dusty rooms. Monthly maintenance includes the following works: a) carrying out activities for weekly maintenance: b) cleaning the surface of pipelines from dust and dirt: c) replenishment of reservoirs with water when the level drops below the design mark: d) tightening of nuts on flange connections of pump nozzles with pipelines and foundation bolts and other preventive work: e) checking the serviceability of the pressure gauges of the pneumatic tank by comparison with the control pressure gauge; f) checking the operation of the installation in manual and automatic modes (if there are no specially trained personnel at the facilities). THAT, carried out every 3 months. includes: a) carrying out activities for monthly maintenance; b) checking the internal fire hydrants located on the sprinkler network (by opening them); c) change of pump oil seal packings: d) flushing and lubricating pump bearings: e) replacement of the stuffing box seals of the compressor; f) checking the operation of the installation in manual and automatic modes (if the facility has specially trained personnel). Annual maintenance includes the following works: a) metrological check of the checkpoint; b) control of the equipment of the fire extinguishing station (inspection and cleaning of the pneumatic tank at the stand; painting the outer surface of the impulse device of the pneumatic tank; cleaning, inspecting and repairing the compressor and fittings; cleaning, repairing and painting the inner and outer surfaces of the pump priming tank: testing the tightness of check valves and gate valves); c) measurement of working resistance and cleaning and repair of control units with replacement of faulty parts, rubber diaphragms and gaskets; d) bulkhead seals of all valves: e) flushing pipelines and changing water in the installation and the tank. Insulation resistance electrical circuits measured every 3 goals during the next annual maintenance. Maintenance, carried out once every 3.5 years, includes the following works: a) disassembly, cleaning of pumps and their fittings, detailed inspection of all parts, repair and replacement of faulty ones: b) hydraulic and pneumatic tests of the pipeline network; c) cleaning of tanks, repair of the waterproofing layer and inlet valves: d) flushing and cleaning of pipelines from dirt and rust with replacement of faulty fasteners; e) painting of pipelines after flushing and cleaning. The specificity of the operation of foam fire extinguishing installations (SCP) is determined by the presence of a foam concentrate or a foam-forming solution in the tanks of the installation, the design of the dosing device and the foam generator (sprinkler). The quality of foaming agents and foaming solutions filled in the UPP is checked at least once a quarter in accordance with the "Instructions for use, storage, transportation and quality control of foaming agents"). Foaming agents are considered unsuitable if the values of their indicators are 20% lower than the normative ones. Defective foaming agents are written off and used either for educational purposes or as wetting additives to water. If the foaming solution or foaming agent is stored in a reinforced concrete tank, then at least once every 3 years the waterproofing layer of the tank is checked and, if necessary, repaired in order to avoid leakage of the extinguishing agent. During the operation of the soft starter, special attention should be paid to the state of foam generators (in particular, mesh), containers with a foam concentrate and communications for its supply, due to the fact that some constituent parts of foam concentrates tend to crystallize, as a result of which the flow cross-sections of pipes, branch pipes, taps may be clogged. During the operation of equipment for protecting tanks with flammable liquids, the condition of the sensors for detecting fire (sprinklers or TRV-2 detectors) installed in the upper part of the tank and the foam chamber (especially its sealing gate) is also checked. After the operation of the UPP of its communication, the elements are washed with water. Periodic maintenance of foam fire extinguishing installations is performed in the same sequence as for water fire extinguishing installations. With the exception of the following work performed monthly: in containers where the foam concentrate or its solution is stored, the safety of the seals on the inspection hatches is checked: if the seals are torn off, the frother or solution is sent for analysis, and the hatches are sealed again; include on a short time dosing devices (for flushing with clean water); the pumps are stirred with a foaming solution or a foaming agent. Once every 3 years, the performance of the soft starter is selectively checked.
