In providing fire safety fire extinguishing systems play a major role in the facility. They must work quickly and be trouble-free. In order for them to be in good working order, they must be regularly checked and any problems identified must be corrected. To do this, maintenance of fire extinguishing systems is carried out. It consists of several stages and many events. Each of them is suitable for a specific occasion. In addition, all processes related to fire extinguishing systems are documented.
Basic Rules
Maintenance of fire extinguishing systems (systems and installations) is partially carried out by the owner or tenant of the facility. The head of the enterprise appoints responsible person, and his responsibilities in this area are prescribed in job description. Most of the work on maintenance carried out by a specialized organization. An agreement is concluded with her, where the conditions are spelled out, including the terms of departure to the site in the event of an emergency call.
All work is regulated by document RD 25 964-90. Basic information about service times, technical parameters contained in the operational documents for the fire extinguishing system or its elements. After installing the equipment, a passport for the system is filled out; it also plays a role in checks and their identification.
Types of jobs
The following types of work are distinguished:
- visual inspection;
- preventive work;
- performance check.
An external inspection allows you to determine the condition of fire extinguishing systems from a technical point of view. During such system maintenance, the specialist conducts a visual inspection of all elements, components and assemblies, and may use measuring instruments. Various defects and damage are detected: leaking pipes, rust on metal parts, separation of elements, etc.
Preventative work As part of maintenance, it must be carried out regularly. They involve cleaning pipes, lubricating mechanisms, and removing rust. A specialist must pay attention to faulty equipment and replace it. It is important that the new elements are similar in parameters to the old ones. Prevention helps prevent the occurrence of malfunctions and defects in fire extinguishing systems.
Functionality testing is a set of technical measures aimed at checking the proper functioning of the system. Because modern systems automatic fire extinguishing equipped with electronics, then external inspection, prevention. Functionality testing should cover not only the technological part, but also the electrical and signaling parts.
According to the regularity of the event, they distinguish following types service various systems fire extinguishing:
- planned (according to the approved schedule);
- unscheduled (in case of false alarms, malfunctions).
Visual inspection and performance checks are carried out at least once a month. The timing of maintenance work is established based on information from operational documents and other data from the manufacturer.
Stages of work
The first task is the mandatory search for a contractor with the appropriate credentials and technical base. Inspections are carried out accompanied by a representative of the customer (owner or tenant of the property).
Maintenance of fire extinguishing installations begins with a study of the facility, equipment and documentation. Next, the specialist analyzes the data obtained and begins to inspect the technological part. As a rule, it includes pipelines, measuring instruments and equipment, electrical equipment, shut-off valves. Then the condition and properties of the fire extinguishing agent are checked. A lot of attention is paid to the electrical parts, as well as to alarm systems. They also measure resistance and monitor the performance of all power sources. There are usually two of the latter - main and backup. Preventative work – intermediate and important stage the entire maintenance process.
After inspection and spot check of all elements, it’s time for prevention. At this stage maintenance various installations fire extinguishing is a kind of test. Even after all the necessary measurements and inspections, malfunctions are often detected. Then repairs are possible, eliminating defects and replacing faulty parts.
The service ends with the preparation of documentation of the work performed. At the end, the specialist approves the result with the customer and gives consultations. Sometimes equipment becomes obsolete and needs to be replaced, and questions may arise about other parts of the system. All work and maintenance consultations must comply with regulatory documents.
Features for various equipment
Since the design of fire extinguishing systems largely depends on the type of fire extinguishing agent, servicing water fire extinguishing systems will differ from checking and inspecting the gas version. The specialist must be competent in these matters and know the nuances of the functioning and device of each type.
Maintenance of water installations and systems involves regularly determining the water level in the tank. During the maintenance of water fire extinguishing systems and installations, the inspector records data on this in a separate log. If the extinguishing agent level has changed significantly without apparent reason, that is, there is a high probability of detecting a tank or pipeline leak. Check every month pumping station, every 2 weeks you need to run pump equipment. In water fire extinguishing systems, pressure gauges are checked every year for serviceability, and the pneumatic tank is inspected at the same frequency.
For service powder fire extinguishing In addition to standard work, a monthly determination of the pressure in the cylinders is included. The data is compared with the normative ones, as is the quality powder mixture, the inspection periods of which are indicated in the technical documentation. After activating the cylinders with fire extinguishing agent resort to purging the containers with nitrogen for cleaning purposes.
System Maintenance gas fire extinguishing also has its own characteristics. The amount of extinguishing agent is usually determined by weighing. There is another option - pressure control. There is a difference in this process for modular and centralized systems. After activation, gas extinguishing agent and propellant gas are refilled, and failed elements (squibs, modules) are replaced. Maintenance of gas fire extinguishing systems involves inspection to identify seals, module markings, and devices to prevent spontaneous start-up of systems and installations.
Water fire extinguishing is traditional method fire fighting. Other types of fire suppression also have a lot of advantages, but they cannot always be used. For example, when extinguishing a fire in a room with people, you cannot use gas or powder, as these substances can harm their health.
Fighting fires with water is a safe, effective, accessible and cost-effective method. It is used for protection administrative buildings, public institutions, banks, sports grounds, office premises, hotels and enterprises for various purposes.
Water fire extinguishing is carried out using deluge or sprinkler automatic systems or manual installation, which do not lose their relevance.
The main components of water fire extinguishing systems are:
- pumping station;
- pipelines (distribution, suction, pressure);
- sprinklers;
- controls;
- tank with compressor;
- devices for measuring water pressure in a cylinder;
- water tank.
Such installations have quite complex design, therefore, maintenance of all their components should be regular.
Maintenance of water fire extinguishing
State technological equipment Water fire extinguishing installations must be registered in a special log, which can only be kept by the responsible person.
The operating condition and efficiency of all components and devices of the system are checked during a complete audit (once every 3 years). During this work, all components of the installation are inspected, and pressure testing of the pressure pipeline and flushing and pressure testing of distribution pipelines are performed.
Testing of the water fire extinguishing system is also carried out once every three years. In this case, a special program is used, which includes the actual start-up of the installation without stopping the main work. During testing, it is necessary to control the water pressure and the intensity of water supply at the first and last sprinklers.
