Design
The gas mask of the described model consists of several parts, each of which has its own characteristics.
Obverse
SHIP-2b is used as a helmet-mask. Its design contains elements such as:
- frame;
- spectacle knot;
- obturator;
- connecting tube.
The tube connects very tightly to the helmet-mask. A nipple is installed at the other end, with its help, a connection is made to a regenerative cartridge. The tube is placed in a cover made of rubberized fabric material. The cover is longer than the tube. Thus, the nipple is completely closed.
Breathing bag
This element is made in the form of a rectangular parallelepiped. It has an inverted and shaped flange. The nipple is installed in a shaped flange. A spring placed inside protects against pinching. The overpressure valve is installed in the inverted flange.
A bag
There are four buttons for fastening on the surface of the bag.Inside the product, the manufacturer has provided a small pocket where the box with the NP is placed.
Frame
This part of the gas mask is made of duralumin. At the top you can see a small clamp for fastening. Its design includes a lock. The markings can be found on the upper bezel. It is made in the form of a small imprint on a plate.
Areas of use of isolating gas masks
Isolating gas masks IP-4 are designed to completely isolate the human respiratory system from the external environment. When using them, a person breathes due to the work of the regenerative cartridge, which produces clean air.
They are designed to work when there is a high concentration of toxic substances in the space surrounding a person, if during use filter type gas mask you can expect a "leak" of hazardous substances, which he is unable to prevent. Isolating gas masks IP-4 are used when there is not enough oxygen in the environment, carbon monoxide reaches high concentrations. When it is necessary to carry out a short stay under water, as well as in cases where the types of toxic substances are unknown.
The most common, frequently used insulating type gas masks are IP-4 and MP-5. A variety of IP-4 MK gas mask is intended for work in an atmosphere hostile to human breathing, which contains chlorine, ammonia, hydrogen sulfide.
The IP-5 gas mask is used, among other things, for performing simple work at a depth, while it can reach seven meters.
A variation of the IP-5 (I / 7-5) gas mask, designed for underwater work, has an additional device for supplying air.
Peculiarities
The IP-4 gas mask is a closed-circuit regenerator first manufactured in the Soviet Union. It was commissioned for military personnel working in low oxygen concentration environments. Began to be produced in the mid-80s. It was released in both black and gray rubber with a gray or light green bag. The lenses of the insulating masks were fixed to the front panel with a metal ring.
The design uses an RP-4 cartridge and a small air bubble to recycle oxygen. The carrier exhales, and the exhaled air passes through the IP-4 balloon, freeing oxygen from chemical elements. At this point, the air bubble deflates and inflates again. This happens in a continuous cycle until the capacity is depleted.
Usage time:
- hard work - 30-40 minutes;
- light work - 60-75 minutes;
- rest - 180 minutes.
The hose cover is made of heavy duty and chemical resistant plastic.
Product weight - about 3 kg. The breathing bag has a capacity of 4.2 liters. The surface of the regenerative bag is heated to a temperature of 190 degrees. In the starting briquette, up to 7.5 liters of oxygen are released during decomposition. The temperature of the inhaled air cannot be more than 50 degrees.
Modifications
Depending on the modification, the technical characteristics of the gas mask may differ.
IP-4MR
The IP-4MP model can be used for 180 minutes if the user is at rest. The more load and more often breathing, the less this indicator. The product includes a mask of the "MIA-1" type, a rubberized breathing bag. The protective housing is made of aluminum.
This gas mask comes with a storage bag. The neck of the cartridge is tightly closed with a stopper. There is an insulated cuff. In addition, a passport is included with the product, as well as detailed operating instructions.
IP-4MK
The design of the IP-4MK gas mask uses MIA-1, a cartridge of the RP-7B type, a connecting tube and a breathing bag. For this model, the manufacturer has thought out a special frame.
IP-4M
Together with the IP-4M gas mask, there is a regenerative cartridge, the design of which includes:
- back cover with a filter installed on it;
- grain product;
- screw;
- starting briquette;
- check;
- rubber ampoule;
- stub;
- seal;
- nipple socket.
In some cases, a lever trigger is used.
With cartridge "RP-7B"
The RP-7B cartridge provides the user with oxygen while using the gas mask. Its principle of operation is simple: oxygen is released from a chemical at the moment it absorbs moisture and carbon dioxide that a person exhales.
A regenerative product with a starting briquette is provided on the body of the product with the RP-7B cartridge. At the moment of destruction of the ampoule, sulfuric acid is poured out, it causes an increase in the temperature of the body. Inside the cartridge is the oxygen necessary for starting.
How to use?
A gas mask, also known as an air purifying respirator, filters chemical gases and particles from the air. Before using, you will first need to make sure that there is a filter for the product, and the mask itself is tightly adjusted and its size matches the face.
It is imperative to keep your gas mask ready for disaster. It is necessary to store such a product correctly, otherwise it may become unusable. The gas mask should fit snugly against the face. This is why it is advisable to have no facial hair and beard. Jewelry, hats are removed. They can lead to a lack of adequate sealing when using the product. The filter is installed in accordance with the manufacturer's instructions.
To activate the product, you need to pull the pin out of the plunger screw and turn the plunger clockwise, then insert the canister into the bag (connecting the air tubes) and finally put on the mask. Now you can start breathing. It must be remembered that the gas mask canister becomes extremely hot during use due to a chemical reaction taking place inside. Therefore, the carrying bag has good insulation on the top. It protects against burns.
The mask is put on in such a way that it fits snugly against the skin. If necessary, its position will need to be adjusted. The gas mask protects against pollutants by filtering chemicals in the atmosphere. You should breathe normally, as well as without a mask. Contaminants are removed from the air as it passes through the filter.
The process looks like this:
- first check the serviceability of the seal on the replaceable cartridge;
- unfasten the lid of the bag and thread the connecting tube;
- unfasten the clamp;
- now you can remove the plugs and start checking the integrity of the gaskets;
- taking a deep breath, hold their breath;
- the nipples on the tube and bag are disconnected at the same time;
- exhale;
- first attach the tube, then the cartridge, fastening the lock on the clamp;
- they activate the starting device, make sure that everything went as it should;
- take a breath;
- zip up the bag.
Basic requirements for operation
The main requirements for the operation of IP, which must be strictly observed, are the following:
in one room, the number of persons working in insulating gas masks cannot be less than two; it is required to establish continuous communication with them; it is not allowed to use unsealed (not sealed) cartridges, as well as to use a gas mask if the starting briquette does not work; it is necessary to carefully monitor the state of the regenerative cartridge, if there are signs of its emptying (insufficient filling of the bag, difficulty in carrying out a full inhalation, poor health), immediately stop working in the PI; you cannot use the PI after removing the mask (face) without installing a new cartridge; it is strictly forbidden to lubricate the parts and connecting surfaces of the gas mask with grease and oil
When preparing a gas mask for use, the instruction for its operation requires the presence of an instructor or manager who are allowed to check the state of the IP.
A brief history of gas masks
The first gas mask was invented in 1915, during the First World War. The Russian scientist ND Zelinsky became its creator. His invention was adopted by the army at war with Germany already in 1916.
The urgent need for gas masks was associated with the fact that the Kaiser's troops for the first time massively used chemical warfare agents in a war. The first gas attack, carried out against French troops on April 22, 1915, resulted in the death and disability of thousands of Frenchmen. Germany carried out the second gas attack in the east against the troops of the Russian Empire. And then she became the cause of significant human losses.
Currently, gas masks are used not only in the military, but also in civilian areas. The scope of their application turned out to be very wide.
Care and storage
It is required to store the gas mask only in accordance with the manufacturer's instructions.
It is very important. It is best to store the device in an airtight box, which in turn is placed in a cool, dry, dark place, such as a closet.
The filter will need to be checked regularly, watch the expiration date. If the expiration date has expired, dispose of the filter according to the manufacturer's instructions.
It is important to remember that storing the gas mask is required in a safe, clean place that can be easily accessed. The product must be protected from dust and dirt
The purpose of using a gas mask is to protect the respiratory system. If it does not function properly, it jeopardizes the health of the user.
Below is a detailed overview of the IP-4 gas mask.
Components
Self-contained gas masks, which use the principle of chemically bound oxygen, consist of the following parts:
- regenerative cartridge and starting device for it;
- a breathing bag equipped with a valve to relieve excess pressure;
- the front part (mask, helmet), equipped with a connecting tube (it has several sizes, usually three);
- frame;
- knapsack with accessories.
Regenerative cartridge IP is designed to absorb water vapor and carbon dioxide, which are released by a person during exhalation, with subsequent supply of pure oxygen to the breathing bag.
It is equipped with a regenerative chemical composition, a starting briquette is mounted in it. When the system is started, sulfuric acid released from the briquette (when the ampoule is squeezed) heats the regenerative substance. A chemical reaction occurs that makes the insulating gas mask work. The starting briquette, in addition to starting the cartridge, is designed to release oxygen for several minutes before the time when the main reaction begins to occur.
A breathing bag is an air container. It has a built-in valve to maintain the air pressure, which should not exceed 40 mm of water column.
The front part (mask) is intended for isolation from the harmful environment of the facial integuments, respiratory organs, and eyes. It supplies clean air from the bag.
The frame protects the breathing bag from external influences; a regenerative cartridge is attached to it.
