All about self-rescuers ShSS-T

Working underground has no details and nuances, as inexperienced people often think. Any equipment can fail, and the result can be unpredictable. Then only emergency measures can prevent serious problems. Therefore, it is important to know everything about the self-rescuers SHSS-T.

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

• 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 conduct 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 with a temperature of no more than 55 degrees will enter the lungs. The mass of the ShSS-T set is about 3 kg. At the same time, 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.

ShSS-T protective products can be used by personnel when leaving hazardous areas. With their help, in addition, the consequences of emergency situations are eliminated immediately after the incident. The device is suitable not only in underground workings, but also in a number of areas of large industry. Most often we are talking about the chemical industry, energy, the production of building materials. Reliable protection of people is guaranteed in any emergency, accompanied by toxic emissions.

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.
