2. Description of the components of the breathing apparatus .

DRAGER PA 94 Plus Basic consists of the following parts:

1. Back (lodgment)

2. Gearbox

3. Sound signal (whistle)

4. Pressure gauge

5. Tee (adapter)

6. Pulmonary demand valve

7. Panoramic mask (Panorama Nova SP)

8. Two air cylinders (Laxfer).

Back (lodgment).

The cradle consists of a plastic plate made of antistatic material (fiberglass-reinforced antistatic duroplast) adjusted to the human figure, which has holes for grasping with hands when carrying a balloon respirator. The wide, padded waist belt allows the device to be worn on the hips. The weight of the balloon respirator can thus be transferred from the shoulders to the hips. All belts are quick-change and made from Aramid/Nomex - a fabric that is non-flammable or self-extinguishing.

On the lower part of the cradle there are: a mount for a pressure reducer and an elastic shock protection element. In the upper part of the cradle there is a cylinder support with a built-in fastening line, which, in combination with a folding bracket, a cylinder fastening tape and a tension buckle, makes it possible to attach various compressed air cylinders.

Each breathing apparatus has an individual number, which is located on the back, has a designation of 4 letters and 4 numbers (BRVS-0026).

Pressure reducer

The pressure reducer body is made of brass. It is attached to the bottom load-bearing frame. On the pressure reducer there are safety valve, pressure gauge hose with pressure gauge, horn and medium pressure hose. The pressure reducer reduces the pressure from the cylinder (10-330 atm.) to 6÷9 atm. (bar). The safety valve is adjusted in such a way that it is activated at a pressure in the medium pressure section of 13÷20 bar. The gearbox does not require maintenance for 6 years, after maintenance - another 5 years (sealed).

Two hoses come out of the gearbox:

Medium pressure hose – the Plus-A lung demand valve and the Panorama Nova Standard P panoramic mask are attached to the medium pressure hose;

High pressure hose – an audible signal (whistle) and a pressure gauge are attached to the high pressure hose.

The minimum pressure at which the reducer ensures uninterrupted operation is 10 atm. This is the guaranteed minimum pressure from the manufacturer, at which human safety is ensured.

Sound signal (whistle) - warning device and 2.4. Pressure gauge

The warning device is adjusted so that it produces an acoustic signal when the pressure in the cylinder drops to the response pressure of 55 ± 5 bar. Activated by high pressure, the whistle uses medium pressure. The alarm sounds until the air supply is almost completely used up. Sustained sound over 90 dBl up to 10 bar (atm.). The whistle is built into the pressure gauge hose. The whistle and pressure gauge are fully protected. The pressure gauge scale is luminescent.

Note: Breathing apparatus is supplied with a set value of 55 bar +/_ 5 bar.

Tee

The tee allows the connection of two 6.8 l/300 bar composite cylinders.

Pulmonary demand valve

The lung demand valve Plus A is switched on with the first breath. To turn off the aircraft, you must press the red key.

Panoramic mask

Panoramic mask Panorama Nova Standard P is attached to the head using a five-ray headband. The mask has a plastic glass frame and a speaking membrane. Glass – polycarbonate. The mask has a valve box - 2 inhalation valves (the first is for breathing, the second is for providing air pressure of 0.25-0.35 atm) and 1 exhalation valve. The exhalation pressure from the panoramic mask is 0.42-0.45 atm.

Compressed air cylinders

The device is equipped with Laxfer metal composite cylinders with a capacity of 6.8 liters with a working pressure in the cylinder of 300 bar (atm.). Depending on the temperature and humidity of the surrounding air, external icing may occur on the cylinder valve, pressure reducer and connection, but this does not matter for the operation of the device.

Each air cylinder has an individual number, which has a designation of 2 letters and 5 numbers (LN 21160).

When going on combat duty, the air pressure in the RPE cylinders must be at least 265 atm. – requirement for this electronic system device automatic control and warnings from DRAGER Bodyguard II(bodyguard).

When opening 2 cylinders, provided that the cylinders contained different pressure, the pressure in the cylinders is equalized, the total pressure drops, air flows from one cylinder to the second (a characteristic hissing sound is heard), since they are communicating vessels. The time of protective action, however, does not decrease.

Requirements for working with breathing apparatus and safety when working with it

1. When working in RPE, it is necessary to protect it from direct contact with open flames, impacts and damage, do not remove the mask or pull it back to wipe the glass, and do not turn off even for a short time. Switching off from RPE is carried out at the command of the GDZS flight commander: “GDZS unit, from breathing apparatus - turn off!”

2. The valve is opened by rotating the handle counterclockwise. To prevent involuntary closure during use, cylinder valves should be opened at least two turns. Do not forcefully twist it all the way.

3. When connecting cylinders, do not allow dirt to get on the threaded connections.

4. When screwing or unscrewing cylinders, the “3-finger” system is used. Do not use force.

5. When activating the lung demand valve into the atmosphere (without a mask - as a backup option), take the first breath after 3 seconds. after air supply.

6. Safety precautions when putting on a face mask: beard, mustache, glasses come into contact with the seals of the face mask and may adversely affect the safety of the wearer.

7. When attaching air cylinders to the back of the device, do not pull the fastening straps with force until the fastener closes (Tavlo system).

8. When servicing a panoramic mask, do not wash it with organic solvents (gasoline, acetone, alcohol). For maintenance, use a foamy solution of baby soap.

9.Drying of the mask is carried out at a temperature of no more than 60 degrees C.

10. During operation, the glass of the panoramic mask must not be wiped with gloves, leggings, or dirty rags, so as not to damage the glass.

11. If, during inspection No. 1 and No. 2 of breathing apparatus, faults are found that cannot be eliminated by the owner, they are removed from the combat crew and sent to the GDZS base for repair, and the gas and smoke protection officer is given a backup apparatus.

The inspection is carried out on the basis of the GDZS by the senior foreman (master) of the GDZS. The results of the inspections are recorded in the inspection log No. 3 and in the personal protective equipment registration card, and a note is also made in the annual inspection schedule.

6. CALCULATION OF PERFORMANCE PARAMETERS

The main calculated indicators of the performance of gas and smoke protectors in an unsuitable for breathing environment are:

· control air pressure in the apparatus at which it is necessary to reach Fresh air(Rk.out.);

· operating time of the fire control unit at the source of the fire (Trab.);

· total time operation of the GDZS unit in an environment unsuitable for breathing and the expected time of return of the GDZS unit to fresh air (Tot.).

The methodology for calculating operating parameters in RPE is carried out in accordance with the requirements of Appendix 1 to the Manual on GDZS of the State Fire Service of the Ministry of Internal Affairs of the Russian Federation (Order No. 234 of April 30, 1996).

The AirGo device occupies a special place in the line. This advanced breathing apparatus is a self-contained respiratory protection device that operates independently of the surrounding atmosphere. The principle of modular design is used, which allows you to create and order the device in accordance with the specific requirements placed on it. A budget version has been developed: AirGoFix.

Description and technical characteristics (TTX) of AirGo devices

Breathing air is supplied to a person from (or several, usually no more than two cylinders) compressed air through a pressure reducer controlled by breathing, a lung demand valve and a full-face mask. The exhaled air is discharged through the exhaust valve of the mask into the surrounding atmosphere. It is exclusively a means of protecting the respiratory system from gases. The device cannot be used for scuba diving.

2. Belts

Exist Various types belts (shoulder and waist belts), each has different properties and wearing comfort:

com- basic harnes: this is the basic set of belts. The material of the belts is non-flammable special polyester; there is no additional padding in the belts.

pro - padded belts. To increase strength and fire resistance, the belts are reinforced with aramid. Special padding of the type (HOMEX®) has been added to the belts. For the convenience of the user, when operating the devices, weight distribution is provided, achieved by padding the shoulder straps complete with a waist belt. Optionally, the waist belt can be mounted on a rotating plate.

mix- mixed set of belts. Aramid fibers are used as reinforcing fibers in the polyester material from which the belts are made. Special padding of the type (HOMEX®) has been added to the belts, as in the pro version. In the manufacture of the waist belt, non-flammable special polyester is used; the belts do not have additional padding, as in the com modification.

MaX - top quality belts The polyester belts are reinforced with aramid, the belts have additional special padding, and at the same time, the shoulder straps are given an unusual S-shape, which in turn ensures the belts guarantee comfort and ease of wearing. The waist belt is mounted in a rotating version, just like in AirMaXX system devices.

eXX- modification for use in extreme conditions(eXXtreme). The eXXtreme shoulder and lap belts are based on the tried and tested AirMaXX harness system. Made from aramid fibers, they have very high strength and are especially fire resistant. The hoses are protected against high temperature And open flame for a set of protective sleeves of shoulder padding.

The design of the belts is specifically designed for repeated use in educational conditions as close as possible to combat, including training using open fire.

3. Lodgment

3.1 Cylinder straps

Belts of various lengths are used to secure the cylinder/cylinders.

Short Cylinder Straps (LS) - for use with one air tank (4L to 6.9L capacity)

Cylinder fastening belt (double) (LG) - for use with one air cylinder with a capacity of 4 liters to 9 liters, or for two cylinders with a capacity of 6.9 (7) to 4 liters.

3.2 Shock absorber (B)

The shock absorber is made of a special plastic resembling rubber and is installed at the bottom of the cradle. Specifically designed to cushion shock and prevent possible damage, in case the AirGo is suddenly dropped down.

3.3 Waist belt plate (SW)

To support the waist belt, a rotating plate of the waist belt is used and is installed on a cradle in its lower part. One of the “chips” of the plate is that it allows the waist belt to rotate, depending on the movements of the person wearing the device. On MaX and eXX configurations, the swivel plate for the lap belt is included as standard equipment, for the pro configuration the rotary plate is optional.

3.4 Cylinder stop(R)

To increase adhesion, due to friction between the cradle and the cylinder, a special device is provided - an elastic stopper.

3.4 Separator (D)

The metal bracket separating the two cylinders serves as a guide for the belt securing the cylinders and is designed to simplify the installation of the two cylinders.

3.5 Receiver-transmitter

A transmitter-receiver (RFID chip) is installed on the cradle. The transmitter operates at a frequency of 125 kHz.

4. Pneumatic system

4.1 Pressure reducer

At the bottom of the cradle there is a pressure reducer. It is provided for both a classic (conventional) pneumatic system and for systems where a single hose is used.

There is a safety valve on the pressure reducer and a combined pressure gauge is connected to the middle hose for connecting the combined pressure gauge. Reducing the air pressure supplied from the cylinder to approximately 7 bar does the job. If the pressure exceeds the permissible limit, the safety valve is activated. This prevents damage to the device while still providing air to the user.

4.2 Single hose pneumatic system

It is possible to manufacture a single hose pneumatic system in the following versions: Q, M, or 3C/3N, as well as CLICK. In a single hose pneumatic system, all hoses (up to five) are connected into one. That is, the hoses used to connect the pressure gauge, warning signal, lung demand valve, special Quick-Fill fitting, as well as the second connection fitting into one, single hose.

The SingleLine single hose system uses a combination pressure gauge. The combination pressure gauge design includes a pressure gauge and an audible warning device. It consists of the pressure gauge itself, a connector for connecting the lung demand valve, as well as an audible warning device. When the air pressure in the cylinder drops to 55±5 kg/cm2, the whistle (signaling device) begins to emit a constant sound signal. The second fitting is used to connect another lung demand valve (this could be a rescue kit, for example).

4.2.1 Modification -Q - with Quick-Fill connection:

The Quick-Fill fitting is a high pressure connector installed on the pressure reducer (Fig. 2).

With its help, you can fill 300 bar compressed air cylinders without removing the device. The outlets for connecting the pressure reducer are made in such a way as to exclude the possibility of accidentally connecting a cylinder with a working pressure of 200 bar.

The Quick-Fill system cannot be used with 200 bar compressed air cylinders.

Further information is contained in the separate Quick-Fill Adapter System Operating Instructions (Part No. D4075049)

4.2.2 Modification - 3C/3N - with additional fittings for medium pressure hoses

To connect medium pressure hoses, it is possible to equip breathing apparatus with additional fittings. They are located on the waist belt. Purpose - connections additional devices, this could be another lung demand valve or a rescue cap.

The additional fitting is available in versions 3C and 3N.

The design of the 3C fitting provides the ability to connect various devices: pulmonary valve of the rescue kit; or saved. Respihood hood, it is possible to connect hose compressed air systems, in which an automatic changeover valve can be used/not used. Can be used with a protective suit, including when performing disinfection work.

Modification 3N is a nipple with a built-in check valve, to connect the following equipment:

DASV (Compressed air apparatus), equipped with an automatic switching valve, and also provides the possibility of using a protective suit when performing disinfection work.

4.2.3 CLICK modification - the device is equipped with the alphaCLICK special fitting system.

alphaCLICK is innovative quick release coupling from MSA. With alphaCLICK it is possible to quickly connect air cylinders to the pressure reducer. This eliminates the traditional, rather time-consuming process of screwing on the cylinders. The connection reliability is as high as with a regular connection.

To disconnect the cylinder, you need to turn the handwheel of the gearbox fitting approximately 20 degrees. Then press on the ring.

alphaCLICK has a built-in flow limiter: if the valve of an unconnected cylinder accidentally opens, the air will not escape quickly from the cylinder. This option increases the level of safety in case of careless handling of cylinders.

In addition, alphaCLICK components have dust caps to protect them from dirt.

AlphaCLICK is compatible with all standard air cylinder valve thread connectors.

There are two versions of alphaCLICK, differing in the design of the fitting and the cylinder connection:

Modification for 200/300 bar cylinders and 300 bar cylinders.

4.2.4 Modification -M - with alphaMITTER (short-range communication receiver-transmitter), installed on the back plate of the breathing apparatus.

The alphaMITTER transmitter is connected to a dedicated port on the pressure reducer via a high pressure hose. The pressure in the cylinders is transmitted in real time to the personal network system (alphaSCOUT).The alphaMITTER transmitter is powered by three batteries (type AA).

4.3 Classic pneumatic system

The devices of the following modifications are equipped with a classic pneumatic system: -S, -Z, -ICU, and also -CLICK. Hoses from the gearbox to all devices are laid individually and are separate. A lung demand valve is connected to the medium pressure hose. The pressure gauge or built-in control unit is located at the end of the high pressure hose.

4.3.1 Modification -S (with signal hose)

This modification has a signal hose. A separate hose (signal hose) is connected to the signal whistle. The whistle is fixed near the person's ear, i.e. the signal will be clearly audible and clearly identified.

4.3.2 Modification -Z - with a second medium pressure hose connection

There is a second fitting for connecting a medium pressure hose; if there is no need to use the second fitting, it is closed with a plug.

With this fitting you can use for:

connecting a second lung demand valve;

rescue kit, ( regular composition: lung demand valve plus full face mask) used to rescue people;

4.3.3 Modification -ICU/ICS - built-in control unit (with or without a key).The built-in control unit serves to control the operation of the breathing apparatus, display, compressed air parameters and alarm status. The ICU unit is used instead of a simple pressure gauge.

It is also equipped with a displacement sensor and a device for manual feed alarm signal.

If the ICU-S control unit has a key, then this key is sent to the "Incident command" control service for identification.

4.3.4 Modification -CLICK - these are devices equipped with fittings with the alphaCLICK system

4.4 Permanent mounting pneumatic system

The pneumatic permanent fastening system is used in the modifications of the devices: -Z, -AE, -AS, -N, and also as an additional equipment - a pressure gauge cover. Hoses from the gearbox to all devices are laid individually and are separate.

4.4.1 Modification - N. In this modification, the AutoMaXX-N lung demand demand valve is permanently attached to a medium pressure hose. AutoMaXX-N with threaded connection RD40X1/7 is used with negative pressure in combination with 3S, Ultra Elite, 3S-H-F1 and Ultra Elite-H-F 1 full face masks with standard threaded fitting.

4.4.2 Modification -AE. In this modification, the AutoMaXX-AE lung demand demand valve is permanently attached to a medium pressure hose. Lung demand demand valve AutoMaXX-AE with threaded connection M45 x 3 is used with overpressure. For use with 3S-PF, Ultra Elit-PF, 3S-H-PF-F1 and Ultra Elite-H-PF-F1 masks with standard threaded fitting.

4.4.3 Modification - AS. In this modification, the AutoMaXX-AS lung demand valve is permanently attached to a medium pressure hose. Lung demand demand valve AutoMaXX-AS with plug-in detachable connection should be used with overpressure. For use with full face masks 3S-PF-MaXX, Ultra Elit-PS-MaXX, 3S-H-PS-Maxx-F1 and Ultra Elite-H-PS-MaXX.

5. Brief (combat) test of the AirGo breathing apparatus

Make sure the lung demand valve is closed.

Open the cylinder valves and check the pressure using the pressure gauge.

The pressure should be within:

for cylinders with a working pressure of 300 kgf: not less than 270 bar

for cylinders with a working pressure of 200 kgf: not less than 180 bar

After this, close the cylinder valves and continue to monitor the pressure gauge readings.

Within 60 s the pressure drop must not exceed 10 bar.

Gently press the lung demand valve purge button, while closing the outlet as tightly as possible. Monitor the pressure gauge readings.

The signaling device (whistle) must operate at a pressure of 55 ± 5 bar.

Put on a full-face mask and check with your palm (by closing the connection hole of the machine for tightness).

Open the cylinder valves completely. If two cylinders are installed, the valves of two cylinders must be opened. This is necessary for their uniform emptying. Connect the lung demand valve to the full face mask. The device is ready for use.

During use

During operation, it is necessary to monitor the operation of the device, periodically pay attention to the tightness of the mask, the reliability of the connection of the lung demand valve, and also monitor the compressed air pressure in the cylinder using a pressure gauge.
