Fire monitor trunks- these are barrels intended for the formation of continuous or continuous and sprayed jets of water with a variable angle of the torch, as well as jets of low expansion air-mechanical foam.
Classification
Combined fire monitors are divided into 3 main groups.
Depending on the type of transportation:
- Portable (P)– are transferred manually;
- Transportable - mounted on a trailer (IN);
- Stationary - mounted on a fire truck.
Kinds
Portable
PLS-20P
The portable fire monitor PLSP-P20 consists of a body (1), pressure nozzles (3), a receiving body (5), and a control handle (6).
The receiving body has a swivel check valve that allows you to connect and replace hose lines to the discharge pipe without stopping the operation of the shaft.
A four-bladed damper is installed inside the body (1) of the barrel pipe.
To supply the VMP for the formation of a water jet, the nozzles on the body are replaced with nozzles for the formation of medium expansion foam (2).
When changing the water nozzle, the consumption of fire monitors changes.
Fire monitor ML-P20
Designed to form and direct a direct compact or sprayed jet of water or a wetting agent solution.
The monitors have stepless adjustment of the spray jet angle from a direct compact jet to a protective curtain of 120 0, which is carried out by turning the handwheel of the nozzle.
- Water consumption not less than 20 l/s.
- The range of the water jet is not less than 70m.
Stationary
Modern universal fire monitors have a more compact design with a system for supplying a spray jet of fire extinguishing agent. The design of curved hollow bodies of revolution allows you to freely manipulate the flow direction with a flow rate of 20 to 150 l/s at a pressure of up to 1.6 MPa (150 l/s - water supply to the entire city district).
Let's take a closer look: Let's pay attention to the appearance of these trunks, such a zigzag shape allows us to exclude (prevent) the effect of "jet thrust".
This effect occurs when the flow of water comes out of the trunk in a straight line, so there is such a thing for trunks with a large flow rate as a sub-stemer (a person who ensures the stability of the main stemmer).
The zigzag shape of the barrels makes it possible to refract the energy of the flow from the liquid and facilitate the manipulation of the barrel by its operator, which greatly simplifies the task during operation.
Since this is an advantage, most fire monitor manufacturers adhere to this technology.
At the end it has a nozzle, with the help of which it is possible to form both compact and sprayed jets when supplying fire extinguishing agents, as well as water curtains.
The name combined and universal makes us understand the possibility of using this type of barrels not only with water, but also when supplying foam.
Characteristics

Ticket number 7 Question 2 Cooling the combustion zone or burning substance; flame cessation mechanism; fire extinguishing agents used: types, fire extinguishing characteristics, scope, application technique for extinguishing a fire
In the practice of extinguishing fires, the following principles of cessation of combustion are most widely used:
1) isolation of the combustion source from air or reduction, by diluting the air with non-combustible gases, of the oxygen concentration to a value at which combustion cannot occur;
2) cooling of the combustion center below certain temperatures;
3) intense deceleration (inhibition) of the rate of a chemical reaction in a flame;
4) mechanical breakdown of the flame as a result of exposure to a strong jet of gas and water;
5) creation of fire barrier conditions, i.e. such conditions under which the flame propagates through narrow channels.
The fire extinguishing ability of water is determined by the cooling effect, the dilution of the combustible medium by the vapors formed during evaporation and the mechanical effect on the burning substance, i.e. burst of flame. The cooling effect of water is determined by the significant values of its heat capacity and heat of vaporization. The dilution effect, which leads to a decrease in the oxygen content in the surrounding air, is due to the fact that the volume of steam is 1700 times the volume of evaporated water. Along with this, water has properties that limit the scope of its application. So, when extinguishing water, oil products and many other combustible liquids float up and continue to burn on the surface, so water may be ineffective in extinguishing them. The fire-extinguishing effect when extinguishing with water in such cases can be increased by supplying it in a sprayed state. Water containing various salts and supplied by a compact jet has a significant electrical conductivity, and therefore it cannot be used to extinguish fires in objects whose equipment is energized. Extinguishing fires with water is carried out by water fire extinguishing installations, fire trucks and water guns (manual and fire monitors). To supply water to these installations, water pipes installed at industrial enterprises and in settlements are used. In case of fire, water is used for external and internal fire extinguishing. Water consumption for outdoor fire extinguishing is taken in accordance with building codes and regulations. Water consumption for fire extinguishing depends on the fire hazard category of the enterprise, the degree of fire resistance of the building structures of the building, and the volume of the production facility. One of the main conditions that external water pipes must satisfy is to ensure constant pressure in the water supply network, maintained by constantly operating pumps, a water tower or a pneumatic installation. This pressure is often determined from the operating conditions of indoor fire hydrants. In order to ensure the extinguishing of a fire in the initial stage of its occurrence, in most industrial and public buildings, internal fire hydrants are installed on the internal water supply network. (Besides this, see ticket #5 question 2 and ticket #6 question 2)
Fire barrels, similar to the weapons elements of the same name, are designed to supply substances that extinguish a fire to the source of ignition. Modern PTV models, in addition, have one more function - they form a jet, it can be compact, sprayed solid and other configurations. Manufacturers offer various devices in terms of design, dimensions, diameter, throughput, configuration, and principle of operation. All of them are in demand in practice, since the equipment and means today are diverse. It is advisable to make the choice of a specific model taking into account the conditions for the upcoming use, NPB 177-99 and the performance characteristics of fire nozzles.
These devices are used to equip hydrants, pumps, columns, cranes, special vehicles, and more. It is this device that provides the formation, supply and direction of a jet of substance to extinguish the fire. Some fire hose modifications can create water curtains or foam. The extinguishing area of manual fire nozzles and modifications with a carriage is determined by the type of device. The latest generation of models allows you to supply compounds or water as far as possible, and form the safety of fire professionals.
Classification
There are different types and types of fire nozzles:
- Manual fire nozzles. They are used to extinguish fires with hand-held equipment. The depth of efficiency does not exceed 5 meters. Special nozzles are provided for working with various substances. The devices are used to eliminate the initial stages of a fire, but in large-scale emergencies they are ineffective.
- Flight devices. This equipment is mainly used on specialized towers and special equipment for firefighters. Models differ in landing height, complete set of nozzles and the presence / absence of regulatory mechanisms. Combined modifications are highly effective, they create a spray jet, it is fed at an angle, which at the same time provides protection for the firefighter.
Important! The choice of this type of PTV, the procedure for operation, maintenance and other aspects are regulated by GOST R 51115-97, 9923-93 and 53331-2009.
Fire monitor marking
Fire monitors - types, characteristics can be found by marking:
- B - working devices installed on car trailers. They are equipped with rotational mechanisms, which increases the range of their use.
- C - stationary equipment, their purpose - a complete set of internal. In some cases, the standards allow them to be equipped with fire fighting equipment and towers.
- D - models with the possibility of remote adjustment. All parameters can be remotely adjusted: switching on and off, the pressure of the fire extinguishing composition and the jet direction, the consumption of fire nozzles and other technical parameters.
- P - universal mobile modification, optimal for pumping units.
Marking of manual models
From the labeling of hand-held devices, you can find out their purpose. Below is a breakdown of the most popular brands:
- RS-50, 50P, 70. These devices belong to the removable category. They allow you to quickly lengthen the sleeve, change or maintain a continuous jet.
- RS 50.01 or 70.01. These are non-removable modifications, they form a continuous water jet, the pressure of which cannot be regulated.
- PSA, RSK, RSP. These are a series of portable devices that are used exclusively at an angle, which ensures the safety of firefighters. Are completed with various nozzles, including for giving of foamy substances.
- RSSC 70. This type of sleeve device is versatile and highly efficient. It is connected to fire-fighting water pipelines at the facilities, allows you to adjust the parameters and configuration of the jet, and is used with any fire extinguishing compositions.
Purpose, device and principle of operation of manual fire nozzles and fire monitors
A typical PS design involves several working modules:
- brass, aluminum or plastic case;
- head for switching with a sleeve, distinguish between pin, sleeve and couplings;
- nozzles that provide the shape of the jet;
- fittings and couplings for attaching additional devices, such as foam generators or sprayers;
- accessories such as a carrying strap.
According to the performance characteristics and the type of extinguishing agent used, manual fire nozzles and equipment with a gun carriage are classified:
- models for creating a small but powerful jet;
- shut-off modifications equipped with a shut-off crane;
- universal models;
- universal modifications that create a curtain;
- combined equipment, for example ORT 50;
- foam devices with low expansion;
- foam models that provide a multiplicity above average are called foam generators - GSP-600.
Tactical and technical parameters of fire nozzles
A description of the capabilities of a particular hose is indicated in the instruction manual that comes with it. Therefore, before buying a product, it is advisable to get acquainted with the documentation. It is important to choose models that meet the conditions of the upcoming operation, and not focus only on price. The following are the main technical characteristics of these devices:
- the maximum pressure for which the PS is designed, the parameter is indicated in atmospheres or in kgf / cm2;
- the maximum volume of fire extinguishing agent that can be released per unit of time, while the operating pressure is maintained in the system, this indicator determines the water consumption of the device, it must correspond to the performance of pumping equipment;
- operating range, calculated at nominal pressure and standard angle.
Note! When choosing, you should be guided by the type of head for commutation with a sleeve. It must correspond to it in terms of connecting parameters.
Application procedure
In order for a person using PS to maintain strength for a long time, but to act productively and purposefully, one should take the proper position of the body, there are several working postures:
- Standing position. The supporting leg is in front, the weight of the equipment and the body is distributed evenly - on both supports. One hand holds the device from below with the palm of the hand and a finger from above. The second one holds the device on the connecting element.
- Knee position. The man puts one foot on his knee. The second is set aside a little forward. One hand holds the PS at the side, the other supports it by the nozzle.
- Lying position. The person lies down with an emphasis on the elbows. The barrel is held in the same way as the standard position.
- Stair position. A man snaps a carabiner onto the structure. The sleeve is also installed on it using a fixture. The hands act similarly to the standing position.
On a note! To redirect the jet in the right direction, the body is rotated and the nozzle is turned there, the position of other parts of the body does not change. When working with shut-off shafts, the valve is opened by the hand holding the nozzle. The line itself must be held by a grenade launcher.
Technical regulations for this type of PTV:
- the jet configuration is formed at the outlet of the nozzle;
- fire extinguishing agents are sprayed evenly throughout the configuration;
- the transformation of the jet configuration from normal to drip is carried out without transitions - in one movement;
- the consumption of extinguishing agents is carried out without stopping its supply to the fire;
- at nominal pressure, the device retains its performance characteristics and ensures the tightness of all elements;
- barrels with a gun carriage are fixed at certain vertical angles;
- changes in the direction of the substation are remotely provided using an electric or hydraulic drive.
The parameters of foam generators are somewhat different from the purpose, design and principle of operation of manual fire nozzles and columns:
- the equipment creates foam with a multiplicity above average;
- foam mixers create a foam solution of the desired concentration;
- tightness and reliability are guaranteed in work.
Features and differences of air-foam models of barrels and foam generators
Air-foam modifications and foam generators are used to create foam. The first devices form compositions of low multiplicity, the second - above average.
- SVPE and SVP. These modifications work with containers. The devices are formed from a housing divided into three chambers, one of them with a discharged space, a connecting head, a casing and a nipple. The fire extinguishing composition passes through the chambers, the discharged space forms foamy masses of it and air. From the device, they enter the hose, and then to the fire.
- GPS. Consist of cassette, body, head and belt. A 6% composition is supplied to the spray device, where it is crushed into separate droplets. On the route to the grids, air is sucked into the substance. The foam itself is already formed in the cassette. The mass is pushed out of the generator by increasing its volume. It is important to protect the mesh cassette from rust and damage.
Safety in the operation of equipment for the formation of fire-extinguishing foam
Employees who have completed specialized courses and successfully passed the exam are allowed to work with PTV. They must have a solid knowledge of the content rules, the procedure for using and the technical regulations of the PS. In addition, employees are required to undergo regular training. The equipment must undergo daily maintenance to keep it working:
- visual inspection of all elements of fire-technical equipment, especially working parts: nozzles, nets, moving parts and handles;
- checking for the absence of contaminants, including the opening through which the formulations are fed;
- check meshes for damage;
- testing the reliability of connections, if problems are identified, they need to be adjusted;
- checking the movements of moving parts in all planes, if a malfunction is detected, the use of lubricants;
- when performing operations, attention should be paid to the pressure indicators on the measuring device;
- upon completion of work, remove contaminants and compounds from the barrel;
- remove liquid from the equipment, this is especially important in winter;
- after use, eliminate the identified malfunctions and wipe the equipment dry.
All of the above applies not only to the barrel itself, but also to the nozzles. Fire nozzles are not allowed near overhead power lines. The distance must not be less than the range of the fire extinguishing agent. The line should be unwound straight, and its contour should not have creases and curvature. There should be no sharp objects near it. Fire extinguishing agents are fed into the hoses with a gradual increase in pressure, this stops the risk of ruptures. After completion of operation, the equipment should be completely dried, this is especially true for metal parts.

Ticket number 7 Question 1 Fire monitors: purpose, device, characteristics. Safety precautions when working with the barrel - the concept and types. Classification and features of the category "Ticket No. 7 Question 1 Fire monitors: purpose, device, characteristics. Safety when working with the barrel" 2017, 2018.
fire monitor- This is an important type of equipment that is designed to extinguish fires. A special device that generates a powerful jet of water or low expansion foam, which is directed by the operator to the fire.
An obsolete name is the term "fire hose". The main feature of the fire fire monitor that distinguishes it from manual is the easel basis. It is on it that the barrel is attached, into which water is supplied under high pressure. A person is simply not able to hold modern hoses in his hand.
Fire monitors not to be confused with medium to high expansion foam jet devices called foam generators.
Types of fire monitors
Fire monitor barrel- This is a stationary device designed for repeated use, can be placed indoors or outdoors. Provides water supply to large areas. In addition to direct fire extinguishing, they can be used in man-made accidents for the deposition of gas clouds, cooling tanks, building structures, etc.
Structurally, they are divided into the following types of fire monitors:
- Stationary monitors. - They are mounted on special platforms or towers.
- Transportable fire monitors- mounted on trailers.
- Portable fire monitors- they can be transported in a special compartment of a fire brigade vehicle and quickly deployed by fighters.
The fire monitor can have manual or mechanical control, it must be provided with mobility both in the vertical and in the horizontal plane. The maximum rotation angles depend on the specific device model. The material for the manufacture of drugs are metals - steel or aluminum.
Marking according to GOST
The marking contains a letter indicating the type of design fire monitor:
- "C" - stationary (can be fixed directly on the fire truck).
- "B" - transportable, (transported on a special trailer).
- "P" - portable fire monitor (PLS)
Also in the marking there are numbers that determine the rate of water flow in liters per second and the letters of the drug (that is, the fire monitor).
Additional designations:
- "U" - adjustable angle of the torch.
- "D" - with remote control.
- "O" - open, not blocked, with variable water flow.
For example, LS-S20 (15)U - fire monitor, stationary, with a controlled torch.
Stationary fire monitors
Recommended by the fire brigade at all facilities, a variant of the installation of fire-fighting equipment, which localizes and suppresses the source of fire as quickly and efficiently as possible. Stationary fire monitor must be firmly and securely fastened and always ready for use. The serviceability and readiness of these devices are monitored by specially appointed persons responsible for fire safety at the facility or enterprise.
This model of fire equipment is a device for generating and directing a water stream or foam material to extinguish large-scale fires. On stationary fire monitor a flange clamp is provided for connecting the trunk itself and the pipeline riser. A special branching is necessary to increase and decrease the angle of the receiver installation. The switch is needed to change the operating modes of the equipment, depending on the material being fed: “V” or “P” (water or foam). The locking mechanism is designed to secure the monitor assembly in a certain vertical position. The stem tube generates a stream of foam or water at the outlet, and the air-foam casing is the "foam jet generator".

Portable fire monitors
According to the fire safety rules, it is allowed to use portable fire monitors at less dangerous fire hazardous objects. This makes it possible to achieve some cost savings, since portable shafts will be required less to protect a territory comparable in area than installed stationary devices. However, it should be borne in mind that the deployment of the FLS will take several minutes of precious time, which can be decisive during a fire.
Portable fire monitors used in situations where a specific flow pattern of water or foam is required. Depending on the target, portable fire monitor It can deliver a solid water jet or a spray at an angle that can be easily adjusted. Also, this barrel can produce air-mechanical foam material with a low proportion of expansion. Such equipment is essential for extinguishing fires, lowering the temperature inside architectural and engineering structures, as well as for processing places where clouds of gases, vapors and dust settle, which have a toxic or radioactive effect on the environment.
Some design features portable fire monitors:
- relatively small size and, as a result, a small mass;
- the ability to quickly change the types of flow: continuous and sprayed;
- the presence of stability supports for installation on the surface;
- the presence of a manometer;
- removable nozzle with control of the amount of extinguishing agent dispensed.
