Requirements for the premises of a gaseous fuel boiler room. Requirements for the premises of a gas boiler room

It may pose an increased danger, therefore special requirements must be placed on the room where it will be installed. A complete list of requirements for the premises of a gas boiler room can be found on the Rostechnadzor website by referring to the relevant building codes and regulations - SNiP “Boiler Installations” and “Gas Supply”.

Below we present the most essential requirements that make it possible to assess the organization’s prospects gas heating on a specific object. When designing or installation work the engineer must be guided by complete SNiP.

To accommodate a gas boiler with a power of up to 60 kW

There is no need to allocate a separate room; installation in the kitchen is acceptable. Almost all wall-mounted boilers and some floor-standing boilers fall into this category. The kitchen room must have the following characteristics: ceiling height of at least 2.5 m, volume more than 15 mᶟ + 0.2 mᶟ for each kW of boiler power. Supply and exhaust ventilation should provide three times the air exchange in the room per hour + the influx of air volume necessary for fuel combustion. A necessary condition is the presence of a window.

Gas boiler house with power up to 150 kW

can be located in a separate room on any floor of the house or in the basement. The room must be provided with natural light, and its walls, common with other rooms of the building, must have a minimum fire resistance of 0.75 hours. The minimum ceiling height is 2.5 m, and the minimum volume is 15 m². Ventilation should provide 3 times air exchange in 1 hour + air necessary for the fuel combustion process.

For a boiler room with a capacity of up to 350 kW

suitable room on the first or ground floor or in the basement. The ceiling height must be at least 2.5 meters, and there must be natural light in the room. The fire resistance of walls common with adjacent rooms must be more than 0.75 hours. The dimensions of the room must provide convenient access for maintenance equipment. Supply and exhaust ventilation must be designed to provide triple air exchange in 1 hour + air supply for gas combustion.
If the gas boiler room is located on the first or ground floor, as well as in the basement, it must have a separate exit to the street. The door leading from the boiler room to the interior of the house must be fireproof.

In some cases, for example, to provide heating to an already built private house, the best solution may be to add a separate room for a gas boiler room. The attached premises have their own requirements, we list them (boiler power up to 350 kW):

  • the distance along the plane of the wall of the main building from the extension to the window or door openings must be more than 1 meter;
  • the extension wall should not be structurally connected to the wall of the main building;
  • requirements for room dimensions, ventilation, lighting, etc. correspond to the requirements for premises of built-in boiler rooms of the appropriate power.

Underground installation is possible in non-passable channels with removable ceilings with minimal deepening of the channels without backfilling. In places where channels adjoin the outer wall of buildings, the channels must be filled with sand or have diaphragms made of materials from the NG group.

Boiler houses supply heat to residential, administrative buildings and industrial facilities. There is a centralized (several objects from one source) and independent heating. Boiler houses are located in separate buildings or built into a complex of structures (central, autonomous, roof).

Requirements for buildings and equipment

The purpose of a set of fire safety measures is to ensure the safety and health of people who serve boiler equipment. These measures must cover all areas of the boiler room’s activities, requirements for the building must be met, building materials, equipment, fuel storage, operation and repair work.

Fire safety requirements for the boiler house building are indicated in terms of reference for construction. Before the construction of the building, the project is approved by the territorial department of the Ministry of Emergency Situations.

The degree of fire resistance of walls, ceilings, floors, internal partitions The boiler room must comply. Materials are used that do not burn, do not support combustion, and do not emit toxic substances in the event of a fire.

The doors at the exit from the boiler room open outward. Window openings are structures that can be easily dropped in the event of an explosion of a gas-air mixture; they must correspond to the design area and design.

The distance in front of the boiler front should ensure the safety of the operator when igniting the burner, and provide the opportunity to avoid uncontrolled flame emission.

The gas pipeline at the entrance to the boiler room is equipped with an electromagnetic shut-off valve, which shuts off the fuel supply when the gas analyzer is triggered or the electricity is turned off.

The power supply to the boiler room is carried out in accordance with explosion and fire safety requirements. Protection eliminates the risk of fire when short circuit or network congestion. A device is provided in the boiler room emergency lighting, lightning protection and grounding (oil or gas pipelines, including).

Boiler houses are classified as high fire hazard production facilities and are equipped. A fire cabinet (wall-mounted, built-in or attached) is installed next to the fire hydrants and sealed. On the cabinet door there is an explanatory letter, tap number and fire department telephone number. The location of fire hydrants must provide access to two jets (with a given pressure and flow rate) to each point in the room.

Operational safety

The chief engineer organizes the work and monitors compliance with the approved “Fire Safety Rules in the Russian Federation” at the enterprise. Responsible for fire safety the facility is obliged to conduct introductory, primary, repeated, targeted and unscheduled briefings at the workplace with employees.


Classes on fire safety standards are regularly organized for boiler house workers. Planned fire drills are carried out once a year to develop skills and coordinated actions of workers.

The company's regulations prescribe the actions of workers in the event of a fire. The evacuation plan, signs with emergency call numbers for fire services and instructions for personnel actions in case of fire are posted in prominent places.

When operating the boiler room, it is prohibited:

  • allow personnel to work without special training and qualification certificates;
  • operate equipment with faulty burners and fuel supply systems (gas, fuel oil);
  • work with switched off or faulty instrumentation automation (monitoring, adjustment);
  • supply fuel (gas, fuel oil) to the firebox when the burner is extinguished;
  • start the boiler without purging;
  • use the surfaces of boilers and steam pipelines for drying things (working clothes);
  • store gas cylinders (propane, oxygen), gasoline and other flammable liquids;
  • smoking in the workplace;
  • carry out temporary hot work without complying with regulations (work permit);
  • work in oil-soaked overalls.

The boiler room is equipped and designated as a permitted smoking area.

Passages in the boiler room provide access to process equipment. Do not store flammable or other materials in aisles, blocking escape routes in case of fire.

Clean and used rags are stored in specially designated areas, in closed containers. Used cleaning material is removed from the boiler room at the end of the shift and disposed of.

The chimneys of boiler houses that burn coal or wood are equipped with spark arresters. Highly flammable combustion residues are cleaned to prevent chimney fires. Soot from the surfaces of the economizer pipes is removed by steam blowing.

Alarm placement

A fire alarm system is installed in boiler rooms for timely detection of a fire, warning of danger, shutting down equipment and extinguishing a fire. Modular boiler rooms are equipped with an autonomous fire alarm system at the production stage. The choice of the type of autonomous fire alarm for stationary industrial boiler houses depends on the type of fuel used in them.

Sensors (smoke, heat, light, ionized, manual and combined) transmit a signal via a loop to the control panel or junction box. The detectors are located on the ceiling, away from air conditioners and ventilation. When the device is triggered, an alarm sound signal is generated.

Fire alarm devices in the boiler room have an uninterrupted power supply (220V network and backup power supplies).

Using Inventory

The procedure for using fire-fighting equipment depends on the type of fire. For example, powder and carbon dioxide fire extinguishers can be used to extinguish class E fires. Burning fuel oil is thrown with sand, moving from the edge to the center.


The locations of primary fire extinguishing equipment are indicated. Fire extinguishers (powder, foam, carbon dioxide) are located near technological equipment boiler room Required quantity and the type of fire extinguishers is determined according to the requirements specified in the technical documentation for the equipment. Each fire extinguisher is issued a passport and assigned a serial number.

Maintenance and recharging are carried out by organizations licensed for this type of activity. The shut-off valve of the fire extinguisher is sealed. , felt, felt are stored in metal cases in places where it is necessary to protect equipment from sparks and open flames in case of fire.
