Mine self-rescuer shss-1p

User opinion [edit]

In non-emergency times, the rescuer has the only practical use - he can sit on it while waiting for the bus, cage, etc. But it brings a lot of inconveniences:

• you are supposed to always keep it with you. Even if a person works in longwall, reclining, picking coal with a shovel, the rescuer should be at arm's length. Naturally, no one takes them into the lava, for which they can be punished;
• when riding on a belt, the lifeguard belt constantly strives to catch on to something;
• each self-rescuer has a number by which the worker can be easily identified and, if necessary, punished;
• water can be carried on the lifeguard strap.

There is also a version of the self-rescuer in a plastic case ShSS-1P. The technical and operational qualities do not differ from the “big brother” of the ShSS-1U, but the plastic case has low strength and high cost, and therefore received a negative reputation among the miners.

• I have to remember, so as not to forget him (especially "young workers"), there were times when they forgot, and returned for him several kilometers.
• you have to hide it so that outsiders don't crush it or bury it. There were cases - he comes, and the rescuer has already been forgotten, or crushed by the section.
• before the jokes were to tie a fifteen to the rescuer with a bolt.

At the non-gassed mines of the Eastern Donbass (Rostov Region), the filtering self-rescuer SPP-4 was mainly used

Peculiarities

The modern mine self-rescuer ShSS-T fully complies with the TR CU standards. Its main components are:

• automatic start-up device;
• goggles to protect eyes from dust and suspended matter;
• outer case;
• mouthpiece equipped with a corrugated tube;
• bag for full breathing;
• clip for wearing on the nose.

Working out the rules for using this self-rescuer is carried out on two types of simulators.

• On the T-SHS type simulator, it will be possible to carry out up to 1000 workouts for one trainee.
• Full simulation of real conditions is guaranteed on the RT-SHS version.

Mine self-rescuers themselves have been used for underground work in various coal basins of our country for over 20 years. The use of these protective devices, according to manufacturers, guarantees a reduction in the danger of various chemical threats by at least three orders of magnitude. The operation of self-rescuers is allowed at temperatures from -20 to +40 degrees.

The action time is at least 60 minutes with moderately heavy loads. This parameter is calculated on the assumption of leaving the emergency zone with an average speed of 5.6 km / h. If in a critical situation the user of the self-rescuer runs, then the resource will definitely last for 18 minutes. When the tactic of waiting for help on the spot is chosen, the working time is increased to 4 hours and 20 minutes. Resistance to breathing during moderately strenuous work is a maximum of 980 Pa (in other units - 100 mm. Water column).

Speaking of the characteristics of the self-rescuer, the operating temperature of the inhaled mixture cannot be ignored. If the user performs moderately vigorous actions, and the ambient temperature is up to 20 degrees, then air will enter the lungs with a temperature of no more than 55 degrees. The weight of the ShSS-T set is about 3 kg. In this case, the working parts directly weigh no more than 2.4 kg.

The device fully complies with GOST 1983. And also, of course, the requirements of a more current standard. The dimensions are 11.3x14.6x24.5 cm. The response time in a critical situation (with connection) is no more than 15 seconds.

The principle of operation of the self-rescuer shss tm

The principle of operation is to ensure the isolation of the respiratory system. When the device is turned on, the contact of the human respiratory system with the external environment is blocked, a breathing circuit is created in which a breathable composition is maintained.

Mine self-rescuer shss tm - parameters

Protects the respiratory system in an atmosphere that contains the following elements.

In the event of a sudden explosion, fire, coal or gas release, or in the event of another similar emergency, it is necessary to immediately put on the mine self-rescuer shss tm and follow the exit according to the evacuation plan, or along the route indicated by the person of the local supervision.

Only persons who have studied it, who have mastered the safety measures, the rules of use and have acquired practical skills, may be allowed to use the device.

Step-by-step instructions for inclusion in a remedy

• First of all, you need to hold your breath.
• Place the self-rescuer in front of you.
• One hand should hold the device while the other opens the tie strap behind the buckle strap.
• Next, you need to discard the tie strap, bottom and top covers.
• Holding the self-rescuer, you need to grab the mouthpiece, pull it up, remove it from the plug (at the moment, the check is being removed from the starting device).
• After that, you need to take the mouthpiece in your mouth, put on a nasal clip and continue to breathe.
• The length of the strap should be adjusted so that the corrugated tube does not impede the movement of the head.
• After tightening the belt, you need to free the glasses from the rubber ring and put them on.

Forbidden

• Squeeze the breathing bag with your hands and allow contact with objects surrounding the bag to avoid a shortage of GDS on inspiration.
• When in a gassed area, remove the mouthpiece from the mouth and remove the nasal clip.
• You should leave the emergency area with quick measured steps only if you are convinced of the launch of the launch briquette.
• Draw in mine air before entering a fresh stream.
• To be included for the second time in the used self-rescuer mine shss tm.

Used is the tool from which the user was turned off, regardless of the period of stay in it.

To determine whether the launching briquette has been launched, it is necessary to test the surface of the cartridge in the place of the launching device, it must be heated. Also, a start-up sign is indicated by the filling of the breathing bag and the intake of a warm composition for breathing for inhalation.

Maintenance

Maintenance is carried out until the moment the shss-tm is put into operation. Inspection for faults. Removal of clogging and dust from the surface.

Forbidden

• Use the device as a support, seat, etc.
• Place next to heat emitting devices.
• Wash under water.
• Carry and lift by the buckle strap.
• Put a mining machine and other equipment on the electric locomotive, trolley, and other equipment.
• Fold in bulk, throw, drag, put on one side or with the lid down.
• Save used with new ones.

Storage rules

The storage area can be heated or unheated. Room t range -40 ... + 50 С. Packages should be placed on stacks or racks.If heaters are present, the packages should be at least 1 meter away from them. The containers must fit in stacks in the position with the lids up (two packages in width and seven rows in height). Along with this, there must be a distance of at least 1 meter between the upper rows and the ceiling.

Views

The insulating mine self-rescuer ShSS-1 is popular. This is a single-use apparatus that contains bound oxygen. A pendulum breathing pattern is used. Operating temperatures range from –20 to +40 degrees Celsius. Main parameters:

• protective effect for 60 minutes when driving at a speed of 4 km / h;
• time of continuous work at the stand 50 minutes;
• dimensions with folded shoulder strap 27 cm high and 15 cm wide;
• total weight 3.1 kg;
• average term of normal operation - 5 years.

For demonstration purposes, training self-rescuers SHSS-1T2 are used. The device is optimized for training people as close as possible to an emergency. The designers have worked out the optimal imitation of the sensations that arise when using real rescue equipment. But professionals should still train only in special imitation mines.

OSR 40 is a self-rescuer based on chemically bound oxygen. The device is intended for places not only with a toxic atmosphere, but also with a lack of oxygen. Based on the results of practical work, the service life was increased to 7.5 years (over 10 years, subject to successful testing). A breathing bag with a volume of 7 liters or more is used. The device weighs 2.05 kg.

Manual

Instructions for using the device are as follows:

• hold their breath while inhaling;
• grasping the self-rescuer, as quickly as possible, they put the belt around the neck;
• press the device to the side of the body;
• with the free hand, they quickly pull the belt on the lock;
• when the lock is opened, the lid is torn off and discarded;
• placing the lip of the device in the mouth;
• the mouthpiece plates are precisely set in the interval from the gums to the lips;
• the processes are clamped;
• check if the corrugated tube is twisted;
• pinch the nose with a latch;
• exhale into the apparatus and resume normal breathing;
• pull the shoulder strap using a buckle, but at the same time it is impossible to overtighten the corrugated tube, and also to exclude the pulling out of the mouthpiece from the mouth;
• straighten the heat-insulating element and attach it to the case body with a stretching ribbon;
• take a bag with glasses in one hand;
• pull the fiber with the free hand, tearing the bag;
• take out and put on glasses.

The rules for using the ShSS-T prescribe a daily external review. The control of permeability indicators should be carried out at least once every 90 days. Visual inspection implies an assessment for holes and dents with a depth of more than 1.5 cm. It is also necessary to control the presence of fastening belts and the safety of seals. The self-rescuer is only accepted after testing in the test chamber. The test should show complete retention of the tightness.

Important: if the self-rescuer has been used once, it cannot be reused. It is required to avoid any shock and other mechanical influences

Otherwise, the safety of working qualities and elementary safety of users are not guaranteed. Keep the rescue device with you during any movement inside the mine workings.

Device and principle of operation

The design features of various models may differ from each other depending on their type and purpose. So, hoods are created with a large transparent mask. Most often, a polyimide film is taken for its manufacture. In addition, some types have a silicone mouthpiece, a nose clip, and are equipped with elastic seals that are worn around the neck. Almost all varieties are made with a filter element. Some samples use a sealed collar filter, an aerosol cleaning element with a spring.

The work process for each individual model is also different. Filtering products function due to the constant supply of polluted air streams from the environment. First, they pass through a filter element with a catalyst, subsequently converting to carbon dioxide. A special adsorbent destroys all secretions harmful to humans. The purified air enters the respiratory system.

In insulating self-rescuers, air flows from the external environment are not used. They are powered by compressed air, which is supplied from a small compartment, or by chemically bound oxygen. In units based on chemically bound oxygen, the respiratory mass with exhalation through a special corrugated part enters the cartridge, on which carbon dioxide and unnecessary moisture are destroyed, after which the process of oxygen generation begins.

From the cartridge, the mixture enters the breathing bag. When inhaling, the respiratory mass saturated with oxygen is re-sent to the cartridge, where it is further purified again. After that, the mixture enters the human body. In devices with an oxygen compartment, the entire supply of clean air is kept in a special compartment. When you exhale, the mixture is discharged directly into the external environment.
