Code of fire safety rules SP 5. Fire protection systems

Standard questions and answers for SP5.13130.2009 “Fire protection systems. Fire alarm and fire extinguishing installations are automatic. Design norms and rules"

Section 8

Question: The use of liquid nitrogen for extinguishing, including extinguishing peat fires.

Answer: Liquid (cryogenic) nitrogen is used for extinguishing using special installations. In the installations, liquid nitrogen is stored in an isothermal tank at a cryogenic temperature (minus 195 ºС) and during extinguishing it is supplied to the room in a gaseous state. A gas (nitrogen) fire extinguishing vehicle AGT-4000 with a 4-ton supply of liquid nitrogen has been developed. Liquid nitrogen is supplied in two modes (through a monitor barrel and through a manual barrel). This vehicle allows you to extinguish fires in rooms with a volume of up to 7000 m3 at chemical, fuel and energy industry facilities and other fire-hazardous facilities.

A stationary gas (liquid nitrogen) fire extinguishing installation “Krioust-5000” has been developed, intended for fire protection of premises with a volume of 2500 to 10000 m3. The design of the installation allows nitrogen to be supplied to the room in the form of gas at a stable temperature from minus 150 to plus 20 ºС.

Using liquid nitrogen to extinguish peat fires is challenging. The difficulty lies in the fact that liquid nitrogen must be supplied through cryogenic pipelines over a relatively long distance. From an economic point of view, this extinguishing method is an expensive technological process and because of this it cannot be used.

Question: Application of GOTV freon 114B2.

Answer: In accordance with the International Instruments for the Protection of the Earth's Ozone Layer (Montreal Protocol on Substances that Deplete ozone layer Land and a number of amendments to it) and Government Decrees Russian Federation No. 1000 of December 19, 2000 “On clarifying the deadline for implementing measures of state regulation of the production of ozone-depleting substances in the Russian Federation”, the production of freon 114B2 has been discontinued.

In pursuance of International Agreements and Decrees of the Government of the Russian Federation, the use of freon 114B2 in newly designed installations and installations whose service life has expired is considered inappropriate.

As an exception, the use of freon 114B2 in AUGP is intended for fire protection of particularly important (unique) facilities, with the permission of the Ministry of Natural Resources of the Russian Federation.

For fire protection of objects with the presence electronic equipment(telephone exchanges, server rooms, etc.) ozone-non-depleting refrigerants 125 (C2 F5H) and 227 ea (C3F7H) are used.

Question: About the use of gas fire extinguishing agents.

Answer: Volumetric gas fire extinguishing systems are used for fire protection of objects with electronics (telephone nodes, server rooms, etc.), technological rooms of gas pumping stations, rooms with flammable liquids, storage facilities of museums and libraries using automatic modular and centralized installations.

Gas fire extinguishing agents are used in the absence of people or after their evacuation. The installations must ensure a delay in the release of the gas extinguishing agent into the protected premises during automatic and manual remote start for the time necessary to evacuate people from the premises, but not less than 10 seconds from the moment the evacuation warning devices are turned on in the premises.

pp. 12.1, 12.2
Question: What is the procedure for the duty personnel to act on signals from fire automatic equipment and where is it stated?

Answer: In accordance with the Decree of the GOVERNMENT OF THE RUSSIAN FEDERATION dated April 25, 2012 N 390 On the fire safety regime (as amended on December 24, 2018) section XVIII. Requirements for instructions on fire safety measures in the premises of duty personnel must necessarily include instructions that set out the procedure for employees to act in different situations, including in case of fire. Personal liability is established in job descriptions to the staff.

In accordance with SP5.13130.2009, clause 12.2.1, in a fire station or other room with personnel on round-the-clock duty, provision must be made for the transmission of all installed signals about the operation of the fire automatic system, including a light alarm about disabling the automatic start with decoding in directions (zones) to make decisions on the actions of the duty personnel.

For example, in the event of a failure of the technical means of the system, restoration must be carried out within a time, the definition of which is given in Appendix O, depending on the level of danger of the protected object. Personnel actions are carried out taking into account safety requirements.

The actions of the personnel include unconditionally ensuring the safety of people when using installations and substances that can cause damage to the health and life of people, as well as ensuring the normal operation of fire extinguishing installations.

In accordance with the set of rules SP5.13130.2009 clause 12.2.1, devices for disabling and restoring the automatic start-up mode of installations can be placed:
a) in the premises of a duty post or other premises with personnel on duty around the clock;
b) at the entrances to protected premises if there is protection against unauthorized access.

This provision provides for the personal liability of designated responsible persons in the event of exposure to fire and fire fighting substances to people.

Instructions on personnel actions should take into account the permanent, temporary presence of people in the protected premises or their absence, the ratio of preparation times for the supply of GFFS, supply delays and inertia of the installation, the number of entrances, and the nature of the work carried out in the protection room.

pp. 13.1, 13.2
Question: How is the need for “dedicated fire detection zones” determined?

Answer: In some cases, premises, depending on the location and properties of circulating combustible materials, should be divided into separate “dedicated” zones.

This is due, first of all, to the fact that the dynamics of fire development and its consequences in different zones can vary greatly. Technical detection means and their placement must ensure the detection of a fire in the area in the time necessary to complete the target task.

Significant differences in different areas of the room may include interference similar to fire factors, and other influences that can cause false alarms of fire detectors. The choice of technical means of detection should be made taking into account resistance to such influences.

In addition, when organizing “dedicated detection zones,” one can proceed from the predominant probability of fire in such areas of the room.

Section 13, 14, paragraphs. 13.3.2, 13.3.3, 14.1-14.3
Question: The number and parameters of point fire detectors installed in the room, and the distance between them.

Answer: The number of point fire detectors installed in a room is determined by the need to solve two main problems: providing high reliability fire alarm systems and high reliability of the fire signal (low probability of generating a false alarm).

First of all, it is necessary to identify the functions performed by the fire alarm system, namely, whether fire protection systems (fire extinguishing, warning, smoke removal, etc.) are triggered by a signal from fire detectors, or whether the system only provides fire alarm in the premises of duty personnel .

If the function of the system is only fire alarm, then it can be assumed that Negative consequences when generating a false alarm signal are insignificant. Based on this premise, in rooms whose area does not exceed the area protected by one detector (according to tables 13.3, 13.5), to increase the reliability of the system, two detectors are installed, connected according to logical circuit“OR” (a fire signal is generated when any one of the two installed detectors is triggered). In this case, if one of the detectors fails uncontrollably, the second one will perform the fire detection function. If the detector is capable of testing itself and transmitting information about its malfunction to the control panel (satisfies the requirements of clause 13.3.3 b), c)), then one detector can be installed in the room. In large rooms, detectors are installed at a standard distance.

Similarly, for flame detectors, each point of the protected premises must be controlled by two detectors connected according to the logical “OR” circuit (in paragraph 13.8.3, a technical error was made during publication, therefore, instead of “according to the logical circuit “AND”” one should read “by logical circuit "OR""), or one detector that meets the requirements of clause 13.3.3 b), c).

If it is necessary to generate a control signal for a fire protection system, then during design the design organization must determine whether this signal will be generated from one detector, which is acceptable for the systems listed in clause 14.2, or whether the signal will be generated according to clause 14.1, i.e. e. when two detectors are triggered (logical “AND” circuit).

The use of a logical “AND” circuit makes it possible to increase the reliability of the formation of a fire signal, since a false alarm of one detector will not cause the formation of a control signal. This algorithm is required to control type 5 fire extinguishing and warning systems. To control other systems, you can get by with an alarm signal from one detector, but only if the false activation of these systems does not lead to a decrease in the level of human safety and/or unacceptable material losses. The rationale for such a decision should be reflected in the explanatory note to the project. In this case, it is necessary to apply technical solutions to increase the reliability of the formation of a fire signal. Such solutions may include the use of so-called “smart” detectors, which provide analysis of the physical characteristics of fire factors and (or) the dynamics of their change, providing information about their critical condition(dustiness, contamination), using the function of re-querying the status of detectors, taking measures to eliminate (reduce) the impact on the detector of factors similar to fire factors and that can cause a false alarm.

If during the design it was decided to generate control signals for fire protection systems from one detector, then the requirements for the number and placement of detectors coincide with the above requirements for systems that perform only the alarm function. The requirements of clause 14.3 do not apply.

If the fire protection system control signal is generated from two detectors, switched on in accordance with clause 14.1, according to the “AND” logic circuit, then the requirements of clause 14.3 come into force. The need to increase the number of detectors to three, or even four, in rooms with a smaller area controlled by one detector follows from ensuring high reliability of the system in order to maintain its functionality in case of uncontrolled failure of one detector. When using detectors with a self-testing function and transmitting information about their malfunction to the control panel (meets the requirements of clause 13.3.3 b), c)), two detectors can be installed in the room, necessary to implement the “I” function, but on the condition that the operability of the system is maintained by timely replacement of a failed detector.

In large rooms, in order to save the time of formation of a fire signal from two detectors, connected according to the logical “AND” circuit, the detectors are installed at a distance of no more than half the standard one, so that the fire factors reach and trigger the two detectors in a timely manner. This requirement applies to detectors located along the walls, and to detectors along one of the axes of the ceiling (at the choice of the designer). The distance between the detectors and the wall remains standard.

Appendix A
Question: Please clarify whether a one-story warehouse building of IV degree of fire resistance category B in terms of fire hazard is subject to the installation of automatic fire control and fire control systems.

Answer: According to Table A.1 of Appendix A, one-story warehouse buildings of category B in terms of fire danger with a height of less than 30 m without storage on racks with a height of 5.5 m or more are generally not subject to protection by AUPT and AUPS.

At the same time, the premises that are part of the warehouse building should be equipped with automatic fire control and fire control systems in accordance with the requirements of Table A.3 of Appendix A, depending on their area and category of explosion and fire hazard.

At the same time, according to clause A.5 of Appendix A, if the area of ​​​​the premises to be equipped with an automatic fire alarm system is 40% or more of total area floors of the building, it is necessary to provide for the equipment of the building as a whole AUPT, with the exception of the premises listed in clause A.4 of Appendix A.

Question: Is it necessary to equip an attic with an automatic fire alarm system in a public building?

Answer: According to the institute’s specialists, based on the requirements of clause A.4 and clause 9 of Table A.1 of Appendix A SP5.13130.2009, the attic in a public building is subject to protection by AUPS.

Appendix R
Question: What measures should be mandatory when implementing the recommendations of Appendix R.

Answer: Ensuring minimal probability of false generation of control signal automatic systems Fire protection is one of the important tasks of fire automatic systems. This probability is inextricably linked with the probability of a false fire signal being generated by a fire detector (FD) and a control panel (PPKP).

One of such technical solutions is the use of equipment (PI, PPKP), which makes it possible to analyze not only the absolute values ​​of the controlled parameters environment, but also the dynamics of their change. Even more effective is the use of PIs that track the relationship between two or more environmental parameters that change during a fire.

A common cause of false alarms is dust in the smoke chamber of optical-electronic smoke detectors, contamination of the optics in flame detectors and linear smoke detectors, and malfunction of electronic circuits etc. The presence of PI functions for monitoring its technical condition and transmitting information about a malfunction (dust, contamination) to the control panel allows facility personnel to timely carry out the necessary measures to maintain or replace the PI, thereby preventing false alarms. Identification of a failed (requiring maintenance) PI must be carried out by indicating a fault signal on the control panel and accompanied either by indicating the PI address or by changing the operating mode of the detector indicator (for a non-addressable PI).

False alarms may be caused by electromagnetic interference on detectors, wires and cables of fire alarm loops. Increased noise immunity can be achieved by using “twisted pair” or shielded wires. In this case, the shielding elements must be grounded at points with equal potentials to exclude currents in the shielding braids. It is advisable to lay wires and place the PI and PPKP at a distance from sources of electromagnetic interference.

An important role in reducing the probability of false alarms is played by design decisions that determine the location of PIs, as well as the requirements for their maintenance. Thus, when using flame detectors, it is important to correctly select both the type of PI and their location in order to eliminate the impact of “glare” and background light, leading to false alarms of these detectors. Reducing the likelihood of false alarms of smoke detectors due to exposure to dust can be achieved by more frequent cleaning (blowing) during maintenance.

The choice of certain options for protection against false alarms is determined during the design depending on the fire danger of the facility, operating conditions and tasks solved using fire automatic systems.

This year, the Federal State Budgetary Institution VNIIPO EMERCOM of Russia actively introduced changes to SP 5.13130.2009, dividing it into several separate sets of rules. On this occasion, we decided to put together for you a special selection of all SP 5.13130 ​​projects with changes in 2018. Be careful, they don't work yet!

JV “Fire protection systems. Automatic fire extinguishing systems. Design norms and rules"

According to the draft version, changes to SP 5.13130 ​​occurred in terms of automatic fire extinguishing installations.

The new edition of the draft set of rules is aimed at a more detailed presentation of fire safety requirements, elimination of discrepancies and inclusion of fire safety requirements from SNiPs and requirements excluded from Federal Law"Technical regulations on fire safety requirements."

The development of a new edition of the draft set of rules will make it possible to more accurately interpret the fire safety requirements for protected objects, set out in Articles 42, 45, 46, 54, 83, 84, 91, 103, 104, 111-116 of the Federal Law “Technical Regulations on Requirements fire safety".

This project amends SP 5.13130.2009 in terms of fire alarm systems and control equipment for fire extinguishing installations.

In connection with the entry into force of 01.01.2020 TR EAEU 023/2017 Technical Regulations of the Eurasian Economic Union “On requirements for fire safety and fire extinguishing means,” the draft set of rules takes into account future requirements for technical means (devices, detectors, etc. ). In this regard, it is advisable to introduce the developed set of rules no earlier than 01/01/2020.

JV “Fire protection systems. List of buildings, structures, premises and equipment subject to protection by automatic fire extinguishing installations and fire alarm systems. Design norms and rules"

The draft set of rules was developed to replace Appendix A of SP 5.13130.2009.

As part of the work on the draft set of rules, some provisions of Appendix A of SP 5.13130.2009 were clarified and finalized, and a number of new objects of protection were added - both buildings and premises. At the same time, the protection of some objects by fire automatic systems was considered inappropriate.

The number of point fire detectors installed in a room is determined by the need to solve two main problems: ensuring high reliability of the fire alarm system and high reliability of the fire signal (low probability of generating a false alarm signal).
