Maintenance and inspection procedures for RPE 1 and 2, as well as other work, are carried out in accordance with standards and deadlines, as well as special documentation.

The results of the implementation of the relevant work are documented in special magazines registration.

Basic concepts about the use of RPE

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

Insulating protective equipment not only protects the respiratory system from exposure to harmful substances, but also supply the defender with air suitable for breathing (for example, a device with compressed air, oxygen insulating gas mask, etc.).

Each product has individual time protective action.

Basic requirements for firefighters PPE

  • Long duration of protection (at least 60 minutes).
  • Wide range of operating temperatures (from -40 to 60 °C), and for 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 must operate in the temperature range from -40 to 60 °C.

Breathing apparatuses are divided 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 a command is given by a senior member of the squad. When working with a gas mask you need:

  1. Remove the helmet and hold it in a comfortable position.
  2. Start the lung demand valve (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 breathing apparatus you should:

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

Important! It is prohibited to turn on the devices without following the procedure for checking 1 RPE. The preparatory and executive commands of the senior officer are: “GZDS link, gas masks (devices) TURN ON.”

Types and purpose of checks

The main checks of protective equipment include:

1. Working. This type maintenance is carried out to check the serviceability individual parts the device and its correct functioning. It is carried out directly by the owner of the PPE under the guidance of a senior officer. The check is carried out before each inclusion in the RPE. When carrying out such a check it is necessary:

  • conduct a visual inspection of the front part to ensure there is no damage to the elements;
  • test the air duct system for tightness, serviceability of the pulmonary apparatus and the pressure value at which the alarm device is triggered;
  • Lastly, the air pressure in the cylinder is checked using measuring instruments.

2. The procedure for checking 1 RPE includes:

  • testing the serviceability of the front part;
  • inspect the device for any malfunctions;
  • pressure measurement in the under-mask space;
  • checking the tightness of pressure lines and air duct systems;
  • 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 RPE was not used during this time.

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

The tightness of the pressure lines is examined in accordance with the test procedure 1 RPE SCAD.

Check No. 2 is carried out after checking No. 3, disinfection, replacement of cylinders, and securing 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 valve of the cylinder is opened 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 operational.

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

Rules for storing RPE at posts and vehicles

After checking 1 RPE, the procedure for which is established by law, the protective equipment is placed in special storage areas. Serviceable and faulty devices must be stored in special cabinets or cells in correct position. Each place is equipped with a sign indicating the inventory number and information about the owner.

Each device that is stored at the GDZS post must be clean and suitable for use.

When checking, you should pay attention to the expiration dates of individual parts of the device (for example, regenerative cartridges, oxygen cylinders).

When transporting RPE to a check or repair point, special boxes with cells are used.

Working check of DASV

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

The procedure for carrying out DASV consists of going through the following stages:

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

    1.4 Design and principle of operation of the system
    1.4.1 System design
    The system (Fig. 1) consists of a control and measuring unit located in a portable plastic case 1. The case is closed with a lid 2, has a carrying handle 3, a lid lock 4, an eyelet for a transport seal 5, a compartment for adapters 6 and a locking button 7. In addition, the system includes a dummy of a human head 8 or a test disk 9 with a tube 10.

    Fig.1 Appearance systems

    The housing houses a control and measuring unit. The unit controls, instrumentation and connection devices to the unit (connection coupling and quick-release coupling) are located on the control panel (Fig. 2). The panel contains: connecting coupling 1 (M45x3 thread) with o-ring 2 and plug 3, excess or vacuum pressure release button 4, excess-vacuum switch lever 5, vacuum pressure gauge 6, pump handle lock 7, pump handle 8, reset button reduced pressure 9, quick-release coupling (QCU) 10, reduced pressure manometer 11, stopwatch 12.


    Fig.2 Control panel of the control and measuring unit

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

  • low pressure block;
  • reduced pressure block.

  • Fig.3 Schematic pneumatic diagram of the 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 you press the pump handle, air under pressure is supplied to pneumatic distributor 2, switching 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 coupling 3, intended for connecting the device unit or adapter being tested; pressure-vacuum 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 block through quick-release connection 6. The value of the reduced pressure is controlled by pressure gauge 7. Pressure in the block is relieved by pneumatic distributor 8.

    1.5 Marking
    The marking is on a plate attached to the inner surface of the housing cover. The label states:

  • manufacturer's trademark;
  • product designation;
  • technical specifications number;
  • serial number of the product;
  • month and year of manufacture.
