Forum archive. Working check of the sizod (dasv): the procedure for conducting and performing the main elements Check 1 for the skad of omega devices

The working check of RPE is carried out:

• Before using RPE in an environment unsuitable for breathing, a working check is carried out in accordance with the requirements of the RPE manufacturer's operating manual.
• When replacing a RPE cylinder at the place of extinguishing fires in an environment unsuitable for breathing (classes, training), a working check of the RPE is carried out.
• A working check of RPE is carried out by a gas and smoke protector at the command of the commander of the GDZS link (class leader): “Link, check breathing apparatus”. The time of the working check should not exceed 1 minute.

At the end of the working check, the gas and smoke protector reports to the commander of the GDZS link (head of the lesson) about the readiness for switching on and about the value of the working pressure in the cylinder (cylinders): "Gas and smoke protector Petrov is ready to be turned on, pressure is 280 atmospheres".

Permission to turn on the gas and smoke protector in the RPE is given by the GDZS unit commander (class leader) after reporting to him about positive results working check, serviceability and completeness: "Link, turn on the breathing apparatus".

Inclusion in RPE is carried out directly at the entrance to the environment unsuitable for breathing. The GDZS link returns from the unbreathable environment only in full force. Shutdown from RPE is carried out on fresh air at the command of the flight commander: "Link, turn off the breathing apparatus".

The procedure for conducting a working check

You need to check:

1. Serviceability of the mask and the correct connection of the lung machine to it.
2. Vacuum sealing of the apparatus.
3. The work of the lung machine and the exhalation valve of the mask.
4. Operation of the alarm device.
5. The air pressure in the cylinder(s).

Checking the health of the mask and the correct connection of the lung machine to it is carried out visually. Check the absence of damage to the elements of the mask and the reliability of the connection between the lung governed demand valve and the mask, and for type 2 additionally:

• rotating the lung machine 2 (Figures 6 and 7), make sure that the latch 2.1 is closed;
• make sure that the bypass handwheel 2.4 is in the off position or turn it off by turning it 90° clockwise.

Checking the tightness of the apparatus for vacuum is carried out with the cylinder valve (cylinder valves) closed. To check, you need to tightly attach the mask to your face and try to take a shallow breath.

ATTENTION!!! AN ATTEMPT TO TAKE A SHARP DEEP INHALE MAY RESULT IN LUNG BAROTRAUMA!

If a large resistance is created during inhalation, which does not allow further inhalation and does not decrease within 2-3 s, the device is considered airtight.

For this:

• turn off the mechanism of the lung machine, for which they press the button 2.2 all the way (Figures 5, 6 and 7), fix it for 1 - 2 s, then release it smoothly;
• open the valve of the cylinder (one of the cylinders);
• put on a mask and make a fit;
• after the first deep breath, they are convinced that the lung machine has turned on and excess pressure has arisen in the cavity of the mask, for which they take several breaths and exhalations;
• then, holding their breath, they put their finger under the seal of the mask and make sure that there is a constant flow of air from under the mask;
• remove your finger from under the obturator and, holding your breath for about 5-10 seconds, listen to make sure there is no air leakage.

If leakage is detected, adjust the position of the mask by tightening the straps, avoiding overtightening them, and re-check for leakage. After that, the valve is closed, the lung machine is turned off and the mask is removed.

Checking the operation of the signaling device is carried out in the following sequence:

• open and close the valve of the cylinder (one of the cylinders);
• carefully pressing the bypass button and holding it in this position (type 1) or smoothly turning the bypass handwheel (type 2), bleed air from the internal cavities of the apparatus, while observing the pressure gauge of the apparatus;
• at the time of the sound signal, note the pressure gauge reading and make sure that it meets the requirements of the instruction manual respiratory apparatus.

Checking the air pressure in the cylinder (cylinders) is carried out with the valve (s) open on the pressure gauge. When checking, the pressure gauge reading is recorded, which must be at least 25.3 MPa (260 kgf / cm2).

In order for work in RPE to be safe and the combat mission successfully completed, each member of the unit needs to know and comply with certain safety requirements when working, checking and connecting systems.

Maintenance and the procedure for checking PPE 1 and 2, as well as other work, are carried out in accordance with the standards and deadlines, as well as special documentation.

The results of the performance of the relevant work are documented in special journals registration.

Basic concepts about the operation of RPE

RPE is a device that is designed to protect the senses (breathing and vision) of a person in special conditions.

Isolating protective equipment not only protects the respiratory organs from the effects of harmful substances, but also supply the defender with air suitable for breathing (for example, an apparatus with compressed air, oxygen insulating gas mask, etc. e).

Each tool has individual time protective action.

Basic requirements for fire RPE

• Long duration of protection (at least 60 minutes).
• A wide range of operating temperatures (from -40 to 60 °C), and for the northern regions from -50 to 60 °C.
• An oxygen insulating gas mask must protect human organs for at least 6 hours.
• The given gas mask should work in the temperature range from -40 to 60 °C.

Respiratory apparatuses are subdivided depending on the devices of general and special purpose. The procedure for checking 1 RPE is individual for each type protective agent.

Putting on, taking off and storing RPE

Putting on and taking off protective equipment is carried out only after the command is given by the senior member of the team. When working with a gas mask, you need:

1. Remove the helmet and hold it in a comfortable position.
2. Start the lung machine (to do this, take a few breaths from the protective equipment system).
3. Release the air from under the mask.
4. put on

When working with a breathing apparatus, you should:

1. Remove the helmet and hold it between your knees.
2. put on protective mask.
3. Put on a bag with a rescue device.
4. Put on a helmet.

Important! It is forbidden to turn on devices without observing the procedure for checking 1 RPE. The preparatory and executive commands of the senior in the service are: "Link GZDS, turn on gas masks (devices)."

Types and purpose of checks

The main security checks include:

1. Working. This type maintenance is carried out to check the correctness separate parts device and its correct operation. It is performed directly by the owner of the PPE under the guidance of a senior officer. Checking is carried out before each inclusion in RPE. When conducting such a check, you must:

• conduct a visual inspection of the front part for the absence of damage to the elements;
• test the airway system for tightness, serviceability of the pulmonary apparatus and the pressure at which the alarm device is triggered;
• lastly, the air pressure in the cylinder is checked by measuring instruments.

2. The procedure for checking 1 RPE includes:

• testing the health of the front part;
• inspection of the device for the absence of malfunctions;
• measurement of pressure in the undermask space;
• checking the tightness of pressure lines, air duct system;
• gearbox inspection.

3. Check No. 2 - view Maintenance, which is carried out during the operation of RPE, and also at least once a month, if during this time the RPE was not used.

4. Check No. 3 - a type of maintenance carried out on time, in full and with a given frequency, but at least once a year. All RPEs that are in operation and in reserve, as well as those that require complete disinfection of all components and parts, are subject to verification.

The tightness of the pressure lines is examined in accordance with the procedure for testing 1 RPE.

Check No. 2 is carried out after check No. 3, disinfection, replacement of cylinders, and fixing the product to the gas and smoke protector. This check should be carried out at least once a month and after each use.

The tightness of the air duct system is checked in stages:

• first, the fitting of the rescue device is connected to the adapter;
• then the main breathing machine is turned off;
• then the cylinder valve opens and the air duct system of the device is filled;
• after closing the valve, the system is kept for another 1 minute;
• if the pressure does not exceed 1 MPa, the system is working.

Important! If malfunctions are detected, any protective equipment is removed from and sent to the GZDS base for repair. A spare device is issued for replacement.

Rules for storing PPE on posts and vehicles

After the inspection of 1 RPE, the procedure for which is established by law, protective equipment is placed in special storage places. Serviceable and defective devices should be stored in special lockers or cells in correct position. Each place is equipped with a plate indicating the inventory number and information about the owner.

Each apparatus that is stored at the GDZS post must be clean and fit for use.

When checking, attention should be paid to the expiration date of individual parts of the device (eg regenerative cartridges, oxygen cylinders).

When transporting RPE to the point of inspection or repair, special boxes with cells are used.

Operational Check AHSA

Immediately before each inclusion in the breathing apparatus, the gas and smoke protector checks 1 RPE.

Order conducting DSWA consists of going through the following steps:

1. Carrying out an external examination of the mask, the reliability of the connection of the lung machine.
2. Next, the tightness of the air duct system is tested. At the same time, tightly apply the mask to the face and take a small breath. The system is considered serviceable if there is a lot of resistance during inhalation.
3. After the above operations, the serviceability of the lung machine, the outlet valve, and the pressure values ​​is checked.
4. The final stage is the report to the flight commander.

Checking protection using settings

With the help of installations, for example, KU 9V, it is possible to check 1 PPE "Omega". The procedure is divided into several points:

1. Checking the health of the mask and devices by inspection.
2. Testing the operation of the lung machine, the magnitude of the exhalation valve actuation, excess pressure in the space under the mask. To do this, turn off the machine, open the valve, with a slight movement move the lever to working position. Then smoothly operate the pump until the pressure rises. After that, move the lever to the working position and observe the readings of the manometer. When the pressure stops rising, the exhalation valve opens. Normal indicators are: excess pressure in the space under the mask from 200 to 400 Pa, valve actuation value 600 Pa.
3. At the end of testing, pressure readings are recorded and the tightness of the apparatus systems is checked. To do this, the installation hose is connected, the cylinder valve is opened. Next, you should take readings from the manometer high pressure in a cylinder (the norm is 0.45-0.9 MPa).
4. To test the device for additional air supply and the moment of operation of the signaling device, an additional supply is turned on. It is considered serviceable if there is a characteristic sound of air bleeding and a special sound signal.
5. To check the air pressure, open the cylinder valve and record the pressure gauge readings. The normal working pressure is 25.3 MPa (for DAVS - 260 kgf / cm 2).

The device and principle of operation of the system

• System device.

The system (Fig. 1) consists of a portable plastic shockproof case 1 with a lid 2, a carrying handle 3, a lid lock 4, an eyelet for a transport seal 5, a compartment for adapters 6 and a latch button 7.

The headform (or test disc) is designed to hold the face piece in place when performing breathing apparatus tests.

The MG headform consists of a body 8 with a fitting 9 and a tube 10, through which the undermask space is connected to the system.

The test disk consists of a body 11 mounted on a bracket 12. On the body, a front disk 14 and a connecting nipple 15 with a tube 16 are fixed with a nut 13. The flywheel 17 and the pressure disk 18 mounted on it move along the threaded part of the body using the handle 19.

The device and principle of operation of the MGN headform are given in the instruction manual for the headform.

The control and measuring unit is located in the system case. The unit controls, instrumentation and devices for connecting to the unit (coupling and quick coupling) are placed on the control panel.

On the control panel (Fig. 2) there is a connecting sleeve 1 with a sealing gasket 2 and a plug 3, an excess (or vacuum) pressure release button 4, an excess-vacuum switch lever 5, a pressure gauge 6, a pump handle 7 with a latch 8, a button reduced pressure release 9, quick coupling (BRS) 10, reduced pressure gauge 11, stopwatch 12. A protective cap is put on the quick coupling.

• The principle of operation of the system.

The control and measuring unit of the system consists of two autonomous units (Fig. 3):

• low pressure block;
• reduced pressure block.

Low pressure block.

The source of pressure in the block is a manual piston pump 1 with a spring for returning the pump rod to the working (uppermost) position.

When the pump handle is pressed, air under pressure enters the pneumatic distributor 2, switching of which to one of its positions determines the creation of excess or vacuum pressure in the block. Excessive (vacuum) pressure is supplied from the pneumatic distributor to the coupling 3, to which the tested unit of the apparatus is connected directly or through an adapter, then to the pressure vacuum gauge 4, designed to control the pressure in the block and the pneumatic distributor 5, designed to relieve pressure in the block.

Reduced pressure block.

The reduced pressure from the airway system of the breathing apparatus enters the block through the quick coupling 6. The reduced pressure value is controlled by the pressure gauge 7.

The pressure in the block is relieved by the pneumatic distributor 8.

• Marking.

• The marking is on a label affixed to back wall corps.

The label says:

• product code;
• number of technical specifications;
• serial number of the product;
• date of manufacture (month and year).

The headform is marked on a plate attached to the body of the headform.

The test disc marking is on a plate attached to the bracket.

The headform (or test disc) marking contains:

• trademark of the manufacturer;
• name or code of the product;
• serial number of the product;
• date of manufacture (month and year).

Fig.3 Schematic diagram of the pneumatic system

Low pressure block
The source of pressure in the block is a manual piston pump 1 with a spring for returning the pump rod to the working (uppermost) position. When the pump handle is pressed, pressurized air enters the pneumatic distributor 2, switching of which to one of its positions determines the creation of vacuum or excess pressure in the block. From the pneumatic distributor, excess (vacuum) pressure is supplied to the coupling 3, designed to connect the tested unit of the apparatus or adapter; pressure gauge 4, designed to control the pressure in the block and pneumatic distributor 5 with an adjustable throttle, designed to relieve pressure in the block.

Reduced pressure block
The reduced pressure from the air line of the breathing apparatus enters the unit through a quick-coupling connection 6. The value of the reduced pressure is controlled by a pressure gauge 7. The pressure in the unit is relieved by a pneumatic distributor 8.
