Turning off ventilation and air conditioning systems in case of fire. Turning off air conditioning systems in case of fire

Dear Little Ru

For yours:
“The state examination requires turning off air conditioning systems”

It’s not Gods, or even angels, or computers that work there...
People, people make mistakes.
For various reasons.
They do not have a deep grasp of the ENTIRE boundless sea of ​​information.
Rush.
Steriopit.

I myself am a sinner, I worked in one of the examinations.
30-20 minutes were given for the project along with writing a conclusion.
The projects were naturally delivered on a cart, volumes.
There are 10-12 projects per day.
In terms of diversity and complexity - mother, don’t worry, as they say.

Sometimes there is no time to understand the norm, its essence.

When to figure it out, SYSTEM, not SYSTEM... it’s better not to miss a mistake than to miss it.

The police chief came and defended it if it was important to him.
The point was removed, but of course they didn’t give me a pat on the head for that.
But there were very persistent and competent GUIs.

For information on the topic.
(From another branch).

It may help to work with a clueless expert.

Workshop materials
at the Federal State Institution “Glavgosexpertza of Russia” on June 9, 2009 on the application of the Technical Regulations on Requirements fire safety

For high-quality examination and identification of all violations technical requirements related to the object in question requires high qualifications, which are acquired in the process of many years practical work with regulatory documents and project documentation. Therefore, the reliability of a novice expert’s work is 0.16-0.2. The reliability of an expert's work increases to an acceptable level within 10-12 years.
This is explained by the presence of a large volume of conceptually complex and interconnected regulatory requirements, the number of which exceeds 60,000. With the introduction of sets of fire safety rules and a reduction in the number of regulatory documents, the number of regulatory requirements increases and they become more complex. The enormous capabilities of human long-term memory are offset by the limited capabilities of RAM, which provides professional activity in conditions of time shortage and information overload..

Interpretation of fire safety requirements

In accordance with the provisions of Art. Art. 15, 18, 34, 55 of the Constitution of the Russian Federation; Art. Art. 1-3 of the Civil Code of the Russian Federation and Art. Art. 4, 7 of the Federal Law “On Technical Regulation”, the requirements for the protection of property are interpreted as requirements for the protection of someone else’s property.
If there are regulatory conflicts that cause irremovable doubts, fire safety requirements are interpreted in favor of the developer (customer).

1. Responsibility of experts
for poor quality examination

Criminal liability occurs:
under Article 169 of the Criminal Code of the Russian Federation “Obstruction of lawful entrepreneurial activity", in cases where fire safety systems include high-cost fire prevention measures aimed at protecting own property developer, causing him harm in the form of lost profits, and violating the requirements of Art. 7 Part 2 of the Federal Law “On Technical Regulation”;
under Article 293 of the Criminal Code of the Russian Federation “Negligence” in connection with Art. 217 of the Criminal Code of the Russian Federation “Violation of safety rules at explosive objects” and 219 of the Criminal Code of the Russian Federation “Violation of fire safety rules”, in cases of death or serious harm to their health in fires, in the presence of a cause-and-effect relationship with specific violations of fire safety requirements.

Civil (property) liability arises in the event of damage caused to the owner by the acquisition of an object with violations of fire safety requirements committed during the design, examination and construction by the organizations performing these works.

Administrative responsibility of heads of examination bodies and their structural divisions under Article 3.11 of the Code of Administrative Offenses of the Russian Federation “Disqualification” occurs based on the results of prosecutorial checks of complaints and statements legal entities and citizens, in cases of incorrect classification of violations of fire safety requirements during the examination of project documentation.

Why is it necessary to turn off ventilation and air conditioning systems?

Any facility is served by utility networks that branch throughout its territory. Of course, one of the main systems are the units responsible for air conditioning and ventilation. We will not begin a detailed conversation about their purpose. It is much more important to understand the principle of their interaction with the automatic dispatch center. As many have already guessed, we are talking about the security and fire protection system. The fact is that in the event of a fire situation, turning off the ventilation system will prevent the situation from getting worse. Speaking more in simple language- an increase in air flow and oxygen supply to the fire will make it more difficult to fight it.

But most main problem there will be a transformation of ventilation ducts into " chimneys"! As a result, smoke, moving along the main passages, will fill rooms where there is no fire! This will significantly complicate the evacuation of people in their danger zone!

Types of shutdown of ventilation systems

That is why all modern security and fire protection modules provide for turning off the ventilation and air conditioning system in two ways:

• centralized type of shutdown of energy nodes;
• selective shutdown type.

Depending on the characteristics of the serviced facility and its nature of activity, one of two types of dispatch response may be appropriate. In some cases, it is preferable to select an individual type of shutdown of the ventilation system. Examples of such areas in a building are, for example:

• corridors of evacuation routes;
• vestibule – gateways belonging to categories A and B;
• elevators, engine rooms of categories A and B;
• passages and atriums in their lower part.

If emergency circumstances do not require the evacuation of people or expensive equipment, as well as if there is a real threat of fire spreading to neighboring areas with the possibility of an explosion, choose a centralized type of shutdown of the ventilation system.

The mechanism of the signal to turn off the power of ventilation and air conditioning systems

Signals to air conditioning and ventilation units are supplied from a central control center. Technically, the mechanism of such a signal is implemented in a complex way. There is a break in the electrical supply circuit. This happens thanks to the automatic unit release, which is mounted in the main switchgear ( switchboard). For a more accurate understanding of the nature of the occurrence of the deactivating signal, it is worth understanding that its formation occurs due to the operation of the control, starting unit of the installed fire system.

what ventilation should be turned off in case of fire Greetings to all regular readers of our site and colleagues in the workshop! The topic and purpose of our article today is to clarify, with reference to a specific regulatory document, an important issue - which ventilation systems should be turned off in case of fire. Many people have heard that in case of a fire the ventilation is turned off, and the hood is turned on so that the smoke goes away, and they ask - why does the exhaust ventilation turn off? She's supposed to remove the smoke, right? Therefore, many ordinary people do not understand and they do not turn off anything at all until the firefighters fine them and explain. So, in order to avoid a fine and explanations after the fact, after the fine, let's discuss this issue now, on the shore. So, in a certain room there is an installed automatic fire alarm and this alarm went off and generated a “Fire” signal. Accordingly, the warning system (SOUE) turned on - the sirens rang and the “Exit” signs began to flash. In the same room there is forced general supply and exhaust ventilation. What should happen to them? We read the appendix to Federal Law-123 - set of rules SP7.13130-2013, paragraph 6.24: 6.24. For buildings and premises equipped with automatic fire extinguishing installations and (or) automatic fire alarms, it is necessary to provide automatic shutdown in case of fire of general ventilation, air conditioning and air heating systems (hereinafter referred to as ventilation systems), as well as closing fire protection normally open valves. Turning off ventilation systems and closing fire normally open valves must be carried out according to signals generated by automatic fire extinguishing installations and (or) automatic fire alarms, as well as when turning on the systems smoke ventilation in accordance with clause 7.19. The need for partial or complete shutdown of ventilation and closure systems fire dampers must be determined in accordance with technological requirements. The requirements of paragraph 6.24 do not apply to air supply systems for airlocks in premises of categories A and B. It seems that it is written quite precisely and specifically - the engines of the general ventilation systems themselves must be turned off, as well as the fire-retarding valves must be closed in order to cut off the building compartment, in where the fire occurred from other compartments and prevent the fire factors from spreading through ventilation ducts. If this is not done, then the communications of the stopped ventilation systems, which, like a web, connect the premises of the building with each other, will turn into chimneys through which smoke will pour into the rooms in which there were no fires, and accordingly this same smoke will complicate the evacuation of people from all rooms of the building. Now let’s clarify the reason why it is impossible to turn off the air supply systems to the airlocks of premises of categories A and B (see the text of the standard above). A vestibule-gate with an air supply separates rooms of categories A and B from other rooms of the building. Air flow plays an important role - it creates overpressure in the airlock and does not allow explosive atmospheres to penetrate from rooms of categories A and B into other rooms of the building. Therefore, if you turn it off, there will be a danger of explosion not only in the category A or B room itself, but also in neighboring rooms, which is unacceptable. Taking into account the above, this point is taken into account by the standard. Now, a moment about removing smoke. Yes, indeed, there is a list of rooms in the building from which smoke must be removed, in accordance with the requirements of existing standards. These premises are described in the SP7.13130-2013 mentioned above, section 7, paragraph 7.2: 7.2. Removal of combustion products in case of fire by exhaust smoke ventilation systems should be provided for: a) from corridors and halls of residential, public, administrative and multifunctional buildings with a height of more than 28 m; b) from corridors and pedestrian tunnels of basement and ground floors of residential, public, administrative, residential, industrial and multifunctional buildings when exiting these corridors (tunnels) from premises with permanent occupancy of people; c) from corridors without natural ventilation in case of a fire more than 15 m long in buildings with two or more floors: - production and warehouse categories A, B, C; - public and administrative; - multifunctional; d) from common corridors and halls of buildings for various purposes with smoke-free stairwells; e) from atriums and passages; f) from each production or warehouse premises with permanent workplaces (and for high-rise rack storage premises - regardless of the presence of permanent workplaces), if these premises are classified as categories A, B, B1, B2, B3 in buildings of I - IV degrees fire resistance, as well as B4, G or D in buildings of IV degree of fire resistance; g) from each room on floors communicating with smoke-free stairwells, or from each room without natural ventilation in case of fire: - with an area of ​​50 m2 or more with permanent or temporary occupancy of people (except in emergency situations) with a number of more than one person per 1 m2 of room area , not occupied by equipment and interior items (halls and foyers of theaters, cinemas, boardrooms, meetings, lecture halls, restaurants, lobbies, box office halls, production rooms, etc.); - trading floors of stores; - offices; - with an area of ​​50 m2 or more with permanent workplaces, intended for storage or use of flammable substances and materials, including reading rooms and book depositories of libraries, exhibition halls, storage facilities and restoration workshops of museums and exhibition complexes, archives; - dressing rooms with an area of ​​200 m2 or more; - road, cable, switching with oil pipelines and technological tunnels, built-in and attached and communicating with the underground floors of buildings for various purposes; h) car storage premises of closed above-ground and underground parking lots, separately located, built-in or attached to buildings for other purposes (with parking both with and without the participation of drivers - using automated devices), as well as from isolated ramps of these parking lots. It is allowed to design the removal of combustion products through an adjacent corridor from premises with an area of ​​up to 200 m2: production categories B1, B2, B3, as well as those intended for storage or use of flammable substances and materials. For trading floors and office premises with an area of ​​no more than 800 m2, with a distance from the most remote part of the premises to the nearest emergency exit of no more than 25 m, the removal of combustion products may be provided through adjacent corridors, halls, recreation areas, atriums and passages. If the facility has rooms described in the above paragraph, then smoke should be removed from these rooms and for these purposes it is necessary to install a smoke ventilation system (otherwise known as a smoke removal system). Now, to make it clear, I’ll explain how the smoke removal system differs from a conventional system exhaust ventilation and why the general exhaust hood is turned off by the “Fire” signal of the fire alarm system, and smoke removal, on the contrary, is turned on. It's all about the following. Four points in general ventilation: 1. Air ducts of general ventilation are “stretched” throughout all rooms of the building and are connected in a certain exhaust shaft; 2. In general ventilation air ducts, air ducts of non-standardized metal thickness are often used, as well as flexible elements, perhaps not even metal, but made of polymers and other flammable materials; 3. The performance of exhaust systems is not standardized and may not cope with the flow of smoke and for this reason, partially, smoke may enter other rooms combined in a common ventilation system; 4.Emission heights exhaust system general ventilation are not standardized, they are carried out as necessary and there is a possibility of negative consequences due to the removal of smoke by such a system. And now, the same points, but in relation to the smoke removal system: 1. The air ducts of the smoke removal system serve only a specific room from which it is necessary to remove smoke. If, due to technical necessity, air ducts transit through other premises, then a fire retardant coating is applied to the surface of the air duct ( fire retardant composition or special fire retardant coating or structural protection); 2. The thickness of the air ducts of smoke removal systems is clearly regulated; flexible inserts made of flammable materials are excluded; 3.The performance of smoke removal systems is calculated in accordance with the guidelines for the volume of a specific room; 4.The emission height of the smoke removal system is strictly regulated by standards. For the reasons given above, general ventilation systems cannot be used to remove smoke. Now, the question of fresh air ventilation, which is activated by the “Fire” signal of the fire alarm. If we install a smoke removal system for any of the rooms from the list above, we must understand that it is impossible to endlessly suck out the smoky air from the room, since a vacuum will be created and this same vacuum must be compensated by the flow of air from the outside. It is for this purpose that the standard provides for the need to organize compensatory inflow air into the rooms from which smoke removal is performed. Here is paragraph SP7.13130-2013, clause 8.8: 8.8. To compensate for the volumes of combustion products removed from rooms protected by exhaust smoke ventilation, supply smoke ventilation systems with natural or mechanical impulse must be provided. For natural air flow into the protected premises, openings can be made in external fences or shafts with valves equipped with automatically and remotely controlled drives. Openings must be at the bottom of the protected premises. Valve covers must be equipped with means to prevent freezing during the cold season. To compensate for the flow of outside air into the lower part of atriums or passages, doorways of external emergency exits can be used. Doors of such exits must be equipped with automatically and remotely controlled forced opening drives. Also supply ventilation in case of fire (air pressure) is provided in order to organize excess pressure that prevents the spread of smoke to other rooms (floors) and to the evacuation routes of the building. In this case, air pressure is organized into the premises in accordance with SP7.13130-2013, clause 7.14: 7.14. The supply of outside air in the event of a fire by supply smoke ventilation systems should be provided: a) into elevator shafts (if there are no airlocks at their exits protected by supply smoke ventilation) installed in buildings with smoke-free stairwells; b) in elevator shafts with the “transportation of fire departments” mode, regardless of the purpose, the height of the above-ground and depth of the underground part of the buildings and the presence of smoke-free materials in them stairwells– providing separate systems in accordance with GOST R 53296; c) in smoke-free staircases of type H2; d) in airlocks in smoke-free staircases of type H3; e) in vestibule-gates, located in pairs and sequentially at the exits from the elevators to the car storage rooms of underground parking lots; f) in airlocks with internal open staircases of the 2nd type leading to the premises of the first floor from the basement, in the premises of which flammable substances and materials are used or stored, from the basement with corridors without natural ventilation, as well as from the basement or underground floors. In smelting, foundry, rolling and other hot shops, air taken from the aerated spans of the building may be supplied to airlocks; g) in airlocks at the entrances to atriums and passages from underground, basement and ground floor levels; i) in airlocks for smoke-free staircases of type H2 in high-rise multifunctional buildings and complexes, in residential buildings with a height of more than 75 m, in public buildings more than 50 m high; j) to the lower parts of atriums, passages and other premises protected by exhaust smoke ventilation systems - to compensate for the volume of combustion products removed from them; k) in vestibules separating the car storage premises of closed above-ground and underground parking lots from premises for other purposes; m) in airlocks separating the car storage rooms from the isolated ramps of underground parking lots, or - in the nozzle devices of air curtains installed above the gates of the isolated ramps on the side of the car storage rooms of underground parking lots (as protection options that are equivalent in technical efficiency); m) in airlocks at exits to lobbies from smoke-free staircases of type H2, connecting with the above-ground floors of buildings for various purposes; o) in vestibules (elevator halls) at exits from elevators to the basement, basement, underground floors of buildings for various purposes; p) to the premises of safe zones. It is allowed to provide the supply of outside air to create excess pressure in the common corridors of premises from which combustion products are directly removed, as well as in corridors connected to recreation areas, other corridors, halls, atriums protected by exhaust smoke ventilation systems. For reasons similar to the impossibility of using exhaust general exchange systems for smoke removal, supply general exchange systems also cannot be used to organize air pressure or compensation pressure in case of fire. There are specific requirements for air pressurization systems in case of fire, set out in SP7.13130-2013, clause 7.17. There is also a methodology for calculating the parameters of air pressurization systems for specific premises, which must be followed exactly. In general, it should be noted that the listed fire protection systems smoke removal and support must be designed and installed with sufficient precise calculation, since the “discrepancy” in system performance should not exceed 15%, in accordance with the normatively defined calculation. By the way, the amount of excess pressure on the evacuation door also depends on the accuracy of the calculation, since if this pressure is large enough, then due to the vacuum created, people during the evacuation process simply will not be able to open the evacuation door and escape to a safe zone. This point is also described in SP7.13130-2013, clause 7.16, “B”: b) excess air pressure of not less than 20 Pa and not more than 150 Pa in elevator shafts, in smoke-free stairwells of type H2, in airlocks with floor-by-floor at the entrances of smoke-free staircases of type H2 or type H3, in vestibules at the entrances to atriums and passages from basement and ground floor levels relative to adjacent rooms (corridors, halls), as well as in vestibules separating vehicle storage rooms from isolated ramps underground parking lots and from premises for other purposes, in elevator halls of underground and ground floors, in common corridors of premises from which combustion products are directly removed, and in safe zones; Well, to complete the understanding of the topic, I suggest you carefully read the proposed algorithm for turning off and turning on ventilation systems, according to SP7.13130-2013, clause 7.20: 7.20. Control of the executive elements of smoke ventilation equipment must be carried out automatically (from an automatic fire alarm or automatic installations fire extinguishing) and remote (from the control panel of the duty shift of dispatch personnel and from buttons installed at emergency exits from floors or in fire cabinets) modes. The controlled joint action of the systems is regulated depending on real fire hazardous situations, determined by the location of the fire in the building - the location of the burning room on any of its floors. The specified sequence of operation of the systems should ensure the advanced activation of exhaust smoke ventilation from 20 to 30 s relative to the moment the supply smoke ventilation is started. In all options, it is necessary to turn off the general ventilation and air conditioning systems, taking into account provisions (1). The required combination of jointly operating systems and their total installed power, the maximum value of which must correspond to one of such combinations, should be determined depending on the smoke ventilation control algorithm, which is subject to mandatory development when carrying out calculations in accordance with paragraph 7.18. This concludes the article “which ventilation should be turned off in case of fire”, I hope the topic is covered fully and in detail, all the necessary links are provided and those who have carefully read the article should not have any questions. Publication of the article “which ventilation systems should be turned off in case of fire” in various Internet and media resources is permitted only if all of the following links to our website are preserved.

Interim summary No. 2: ventilation systems should be turned off only in rooms where a fire occurred!!! Further requirements must be looked at in SNiPs and SP.

SP 7.13130.2009 HEATING, VENTILATION AND AIR CONDITIONING (taking into account "...does not apply..."
clause 7.19 The control of the executive elements of smoke ventilation equipment must be carried out ... In all options, it is necessary to turn off the general ventilation and air conditioning systems.
Interim summary No. 3: it is necessary to turn off the general ventilation and air conditioning systems ONLY!!! when turning on smoke ventilation systems.

SNiP 41-01-2003 HEATING, VENTILATION AND AIR CONDITIONING 12 ELECTRIC SUPPLY AND AUTOMATION
12.4 For buildings with AUPT and AUPS...automatic BLOCKING should be provided!!! electrical receivers... ventilation systems... with electrical receivers of smoke protection systems for:
a) shutting down ventilation systems in case of fire...
b) ...
V) …
Notes
1 The need for partial or complete shutdown of ventilation systems, closing fire dampers and opening fire and smoke dampers - according to the design specifications.
12.7 The level of automation and control of systems should be selected depending on technological requirements, economic feasibility and design assignments.
Interim summary No.-4:
1) control of the ventilation system (shutdown in case of fire) must be combined into one unit with control of the smoke ventilation system.
2) both the necessity, and the completeness, and the level of automation when stopping ventilation systems, as well as the level of control (including remote control) over the state of the system - EVERYTHING!!! according to design instructions.
In addition, SNiP 41-01-2003 has several INCORRECTIONS:
--- Who can read Russian, paragraph 12.4?
Ventilation systems are air heating systems (except air-thermal curtains ventilation) + air conditioning systems or
Ventilation systems are only air heating systems (except for air-heat curtains for ventilation and air conditioning). – it’s not clear?
And in any case, whatever one may say, this SNiP is only about air heating and air conditioning systems. It turns out that general ventilation is not included in the concept of a “ventilation system” and cannot be blocked with a remote control???
--- and the question regarding clause 12.5 “Premises with automatic fire alarm systems must be equipped with remote devices located outside the premises they serve” - ??? what kind of devices are these??? Probably to turn off the ventilation systems???. Once again, the standard-setters have to figure it out!!! I would fucking kill him!!!

PPBO 157-90 Fire safety rules in the forest industry
3.1.4.10. In the event of a fire, ventilation must be turned off immediately, with the exception of installations designed to supply air to the airlocks of premises of production categories A and B, as well as ventilation installations serving hardening chambers in the production of fiberboards.

PB 03-595-03 Safety rules for ammonia refrigeration units
7.11. . . . . When a fire signal is received, both the supply and exhaust fans, working for these premises.

PPBO-103-79 (VNE 5-79)
clause 10.3.14. “If a fire occurs in a production room for ventilation equipment, if there are no remote centralized shutdown devices, the supply and ventilation fans must be immediately turned off. exhaust units connected directly or through blowers to the burning room..."
10.5.5. If a fire occurs in a room with emergency ventilation, in order to prevent the spread of fire, it is necessary to turn off the operating emergency ventilation fans.
In large workshops, where turning off emergency ventilation may be associated with gas contamination of escape routes or an explosion in the room, the procedure for turning off emergency ventilation must be consistent with the plan for evacuation of people in the event of a fire.
There's another confusion here.
Where did the fire start????
-- in a production room for placing ventilation equipment (i.e. in a fan room)? or
--- in a burning room (i.e. in any protected room at the facility)?
Who can read Russian? I would kill him again...

FINAL CONCLUSIONS: (taking into account does not apply to...)
1. According to GOST 12.4.009 - only in rooms WHERE A FIRE HAPPENED!!!, ventilation and air conditioning systems should be automatically turned off. Only indoors... - how to implement this? Although these are problems for electricians and machine gunners.
2. According to TROTPB, SP7 and SNIP 41-01 - general ventilation is stopped only in a block with smoke ventilation. If there is no smoke ventilation at the facility, then stop the general ventilation system in accordance with GOST 12.4.009.
3. How and what to stop - everything is decided by the designer with his subcontractors and the customer in the design task.
4. For industrial premises on industrial enterprises– read additionally the special standards (PPBO-103-79, PPBO 157-90, PB 03-595-03 and others that do not contradict TROTPB and GOSTs).
