Description

The utility model relates to personal protective equipment against general industrial pollution, namely, to the special clothing of coal mine workers.

Known protective suit miner coal mining and shale industry (patent RU No. 95227 publ. 06/27/2010), which is characterized by the fact that it consists of a jacket and the lower part of the suit, the jacket and the lower part of the suit are made of cotton polyester fabric, while the jacket is made in the form of a direct silhouette with a central side clasp using buttons and loops, and the yoke is made with a one-piece back without a shoulder seam, along the setting line of which there are ventilation holes, and the lower part of the suit is made with one-piece With a belt, belt loops, a front fastener, with external patch pockets, and the trouser lining is shortened by 20-25 cm, as well as additional lining made of material with polyamide threads and reflective patches are sewn on the suit. The specified suit prevents the penetration of fine dust into the suit and protects the worker from the action of organic liquids and contaminated water.

The disadvantage of this protective suit is that its design uses only one high-density material, ATLAS fabric, to provide protection against coal dust. This material prevents heat transfer between the human body and the environment. And as a result, when performing work of high intensity, it leads to a violation of the thermal comfort of the employee, an increase in skin temperature and a decrease in working capacity.

A protective suit is known for a worker employed in thermal oil extraction of oil (patent RU No. 2656197 published on 05.31.2018), characterized in that it consists of a jacket and the lower part of the suit, while the jacket is made in the form of a direct silhouette, and the yoke on the shelves and the back made of three layers, two inner layers of which are made of moleskin fabric, and the outer layer of teflon fabric, the lower part of the sleeve is equipped with a triangular insert of moleskin fabric, at least one ventilation hole is made in the axillary region of the jacket on a shelf in the patch area, and at least one in the sleeve, the lower part of the suit is made in the form of trousers made of single-layer moleskin fabric.

The disadvantage of this personal protective equipment when used in a coal mine is the presence of ventilation holes through which carbon dust and other contaminants can get on the skin of a person in the process of performing work.

A known set of workwear (patent No. 2522950, publ. 04/10/2013), which is characterized by the fact that it consists of overalls and a removable helmet, while the lower parts of the sleeves and legs of the overalls have sealing sections. The overalls are equipped with pads that provide protection against mechanical damage.

The disadvantage of this workwear kit is the presence of sealing sections that disrupt the employee’s heat exchange with the environment and contribute to the accumulation of heat in the employee’s body, in addition, a helmet and additional pads to protect against mechanical damage hamper the employee’s movements and create additional thermal resistance.

Known dustproof suit (patent No. 14813 publ. 10.09.2000) which is characterized in that it consists of overalls with a hood, the lower parts of the sleeves and legs of the overalls have sealing sections, each of which is formed by a part, the lower edge of which is connected respectively to the edge of the sleeve or leg , and designed for tight coverage of the arm or leg, the upper edge is located inside the sleeve or leg.

The disadvantage of this dustproof suit is the presence of sealing areas with a tight coverage of the arm or leg, which exclude the natural ventilation of the clothing area, thereby leading to a violation of the heat balance and the accumulation of heat in the human body, in addition, the presence of a hood also reduces the rate of heat transfer.

Known miner suit (type B) for protection against general industrial pollution and mechanical influences (Interstate standard. Occupational safety standards system (SSBT). Miner suits for protection against mechanical impact and general industrial pollution. Specifications. GOST R 12.4.299-2017 Official publication. Moscow. Date of introduction 01.07.2018) adopted as a prototype, which is a men's suit consisting of a jacket and trousers, designed as protective clothing for protection against mechanical stress and general industrial pollution in the mining and coal industry.

The disadvantage of this suit is the lack of elements in it that ensure the reduction of thermal resistance of the miner's suit while maintaining the necessary level of protective properties. In addition, the existing design of personal protective equipment (miner's suit) does not take into account the various degrees of contamination of the sections of PPE during operation. As a result, areas less susceptible to pollution, which should have a lower degree of protection against coal dust, compared to other areas, can be considered as excessively isolated as a result of this, a violation of the thermal comfort of the worker also occurs.

The technical result is the creation of personal protective equipment that provides thermal comfort for workers in mines, faces, underground tunnels when performing high-intensity work.

The technical result is achieved by the fact that the back and upper front of the jacket are made of single-layer materials, the back is made of medium density material from 200 to 300 mg / m ³ without shoulder seams, the single-sleeve sleeve consists of two parts, the upper part of the sleeve is made of medium density material from 200 up to 300 mg / m ³ attached to the lateral insert of the axillary region of complex shape, which is cut from low-density material up to 200 mg / m ³ , and above the elbow bend is sewn with the lower part of the sleeve from high-density material over 350 mg / m ³ , the lower front part of the trapezoidal jacket made of high density material over 350 mg / m ^{3 is} sewn with lateral rectangular inserts of medium density material from 200 to 300 mg / m ³ , around the circumference of the lower part of the sleeve and the ulnar region of the upper part of the sleeve at a distance of 1/3 from the edge jackets and strips of retroreflective material are scribbled in the thoracic region of the front of the jacket and the back; strips are also perpendicular to them through the shoulder regions. The connection of parts is made by a blind seam.

Personal protective equipment is illustrated by the following figures:

Personal protective equipment consisting of a jacket and made of single-layer materials. The jacket is made in the form of a direct silhouette, equipped with a collar 1 (figure 1, 2). The upper front part of the jacket 2, the back 5, the upper part of the sleeve 3 and the side rectangular inserts 4 are made of medium density material from 200 to 300 mg / m ³ , for example, ANTISTAT LAIT fabric. The backrest 5 and the upper front part of the jacket 2 are made without shoulder seams. The single-sleeve sleeve consists of two parts, the upper part of the sleeve 3 is stitched with the side insert of the axillary region of the jacket 4 of complex shape, which is made of low density material up to 200 mg / m ³ , for example, PHARMA LIGHT 150 fabric is attached to them, the lower part is sewn up sleeve 6, which is made of high density material in excess of 350 mg / m ³ , which has a dust protection class IV protection class, for example, FAS fabric. The lower front of the trapezoidal jacket 7 is also made of high density material and is aligned with the lateral rectangular inserts 8. On the central part, around the circumference of the lower part of the sleeve 6, in the elbow region of the upper part of the sleeve 3, 1/3 from the edge of the jacket and strips of retroreflective material 9 are scribbled in the thoracic region of the front of the jacket and back 5. From strips of retroreflective material 9 in the chest region of the lower front of the jacket 7 and back 5 are perpendicular through the shoulder regions scribble strip of retroreflective material 9. The strips of retroreflective material 9 are made in accordance with GOST 12.4.281-2014 "safety standards system (SSBT). Special clothing with increased visibility. Technical requirements".

The connection of parts of personal protective equipment is made with a blind seam, the edges are first glued together, then they are sewn from the inside so that the thread does not pass through and does not fall on the outside. Due to this, sufficient flexibility and water tightness of the seam is achieved.

The technical result is achieved by the fact that the design of personal protective equipment includes elements that ensure the reduction of thermal resistance of a set of special clothes, namely:

inserts in the axillary region of the jacket are made of low density material, this allows you to quickly remove excess heat from the human body, and provide rapid evaporation of sweat during intense physical exertion;

the inserts in the front lower part of the jacket, the lower part of the sleeve, made of high-density material, protect the worker from coal dust. Moreover, structurally, these inserts are placed on the personal protective equipment in accordance with the topography of their pollution during the execution of work, as well as with the specifics of labor movements performed by the employee in carrying out his activities in the mine;

inserts of high-density material that create resistance to the heat and mass transfer of the worker with the environment are located mainly in the elbows and abdomen of the worker, i.e. zones with the lowest level of heat during physical exertion, thereby providing additional protection without disturbing heat dissipation, in addition, the proposed high-density material - FAS fabric (FAS) consists entirely of cotton, which does not create a greenhouse effect, removes excess moisture, does not accumulate static electricity, protects against microscopic and ultramicroscopic particles, but does not interfere with gas exchange, including oxygen supply to the skin and carbon dioxide removal;

the back, upper part of the sleeve and the front of the suit are made of medium density material, which allows for intensive heat removal from the employee’s body, promotes moisture removal, and at the same time maintains the necessary level of protective properties against coal dust;

the lack of sealing areas with a tight hand grip, which exclude the natural ventilation of the working space, thereby leading to a violation of the heat balance and the accumulation of heat in the human body;

the absence of additional linings and two-layer materials, provides natural air circulation through personal protective equipment, which is guaranteed to exclude the worker from overheating, as it is well known that with uniform perspiration followed by evaporation of moisture, a decrease in temperature and cooling of the skin occur.

An additional supply of personal protective equipment with cotton underwear will ensure the comfort of the worker and the absorption of excess sweat.

Personal protective equipment provides thermal comfort for coal mine workers when performing high-intensity work, which is achieved only if all the structural features are present.
