Maintenance and inspection of personal protective equipment

The personal safety protection articles used by site construction personnel generally include: safety helmet, safety belt, protective clothing, protective glasses, protective shoes, gloves, etc. For these safety supplies, we should not only use and wear them correctly, but also master the knowledge of simple maintenance, maintenance and inspection

the use and inspection of common safety protection articles is very important to ensure the safety of construction personnel in the process of labor. Because it is often used, people often don’t take it seriously, and it’s easy to ignore its function. Especially, people don’t pay attention to the strict requirements of use, and they can do whatever they want, so it’s very easy to cause malignant accidents

years of practice has proved that the common safety helmet, safety belt and safety net play an important role in protecting the safety of workers in the process of labor. Especially in the construction of transmission and distribution of high, cross, overlapping operations, it has played a magical effect

in order to give full play to the positive role of personal protective equipment in safe construction and make all construction personnel use it more standardized and correctly, it is very necessary to manage and inspect common safety protective equipment< First, safety helmet on the construction site of electric power construction, the safety helmet worn by construction personnel is mainly to protect the head from injury. 1t can protect the head from injury or reduce the degree of head injury in the following situations (1) when flying or falling objects hit the head (2) when the operator falls from a height of more than 2m (3) when the head is likely to be electrocuted (4) when walking or working in a low position, the head may collide with a sharp and hard object the safety helmet should be worn according to the standard and used according to the regulations. 1f it is not worn and used correctly, it will not play a full protective role. Generally, we should pay attention to the following items: (1) adjust the position of the cap after adjusting the position to the proper position before wearing the safety helmet, and then fasten the elastic belt in the cap. The elastic band of the cushion is adjusted, and the vertical distance between the top of the head and the top of the cap body is generally between 20 ~ 50mm, at least not less than 32mm. Only in this way can the cap body have enough space for buffering when it is impacted, and it is also conducive to the ventilation between the head and the cap body (2) don’t wear the helmet askew, and don’t wear the brim behind your head. Otherwise, the protective effect of safety helmet on impact will be reduced (3) the mandible belt of the helmet must be buckled under the jaw and fastened firmly with moderate tightness. 1n this way, the helmet will not be blown off by the strong wind, or touched by other obstacles, or fall off due to the back and forth swing of the head (4) on the top of the safety helmet body, the inner part of the helmet body is equipped with a cap lining, and some of them are also provided with small holes for ventilation. But when using, do not open the hole for the sake of ventilation. Because this will reduce the strength of the cap body (5) the safety helmet will be damaged gradually during use. Therefore, it is necessary to check regularly to see if there are cracks, dents, cracks and wear. 1f any abnormal phenomenon is found, it should be replaced immediately and scrapped (6) it is strictly forbidden to use the safety helmet with only the lower jaw belt connected to the cap shell, that is, the safety helmet without buffer layer in the cap (7) construction personnel are not allowed to take off the safety helmet, put it aside, or use it as a cushion in the field operation (8) the safety helmet is mostly made of high-density low-pressure polyethylene, which has the properties of hardening and metamorphosis. So it’s not easy to be exposed to the sun from time to time (9) for the new safety helmet, first check whether there is the production certificate and product qualification certificate allowed by the labor department, and then check whether it is damaged, uneven thickness, and whether the buffer layer, adjusting belt and elastic belt are complete and effective. 1f it does not meet the requirements, it shall be replaced immediately (10) safety helmets should also be worn when working indoors, especially when working live indoors, because safety helmets can not only collide, but also insulate (11) when using safety helmet, keep it clean and tidy, do not touch the fire source, do not paint at will, and do not sit on a stool to prevent loss. 1f it is lost or damaged, it must be reissued or replaced immediately. No one is allowed to enter the construction site without safety helmet2. Safety belt on the construction site of electric power construction, there are many overlapping and cross operations. 1n order to prevent the operator from falling at a certain height and position, the operator must fasten the safety belt when climbing or working at height. The use and maintenance of seat belts have the following requirements: (1) we must pay attention to the role of seat belts ideologically. Numerous examples have proved that the safety belt is a “life-saving belt”. However, there are a few people who have trouble with their seat belts. 1t’s not convenient to go up and down, especially for some small and temporary jobs. They think that “when there is time to fasten their seat belts, all the jobs are finished.”. As everyone knows, the accident happened in an instant, so the work at height must be in accordance with the requirements of the safety belt (2) before using the safety belt, check whether the rope is deteriorated, whether the clasp is cracked, and whether the spring jump is good< (3) if there is no fixed place for the safety belt in the work at height, the steel wire rope with appropriate strength or other methods should be used. 1t is forbidden to hang the safety belt on the moving, sharp or insecure objects< (4) hang high and use low. When the safety belt is hung at a high place and people work below, it is called hanging high and using low. This is a relatively safe and reasonable scientific method. 1t can reduce the actual impact distance when there is a fall. On the contrary, low hanging and high using. That is, the safety belt is hung at a low place, while people work on it. This is a very unsafe method of hanging, because when the fall occurs, the actual impact distance will increase, and people and ropes will be subject to greater impact load. Therefore, the safety belt must be hung at the same time for low use, and it is forbidden to hang at the same time for high use (5) the safety belt should be tied to a solid component or object to prevent swing or collision. The rope should not be tied, and the hook should be hung on the connecting ring (6) the protective cover of the safety belt rope should be kept in good condition to prevent the rope from wearing. 1f it is found that the protective sleeve is damaged or falls off, it must be added with a new one before use (7) it is forbidden to lengthen the safety belt without permission. 1f 3m or more long ropes are used, buffers must be added and all parts shall not be removed (8) before using the safety belt, check whether all parts are intact. Safety belt should be maintained and kept after use. 1t is necessary to check the sewing part and hook part of the safety belt frequently, and check whether the twisting thread is broken or damaged in detail (9) the safety belt should be kept properly when not in use. 1t should not be exposed to high temperature, open fire, strong acid, strong alkali or sharp objects. 1t should not be stored in a wet warehouse (10) the safety belt should be inspected once after two years of use. 1f it is used frequently, it should be inspected regularly. 1f it is abnormal, it must be replaced immediately. The safety belt that has been used in regular or sampling test shall not be used again< 3. Protective clothing workers on the construction site of electric power construction should wear work clothes. There are the following types of protective clothing: (1) full body protective clothing< (2) anti virus work clothes< (3) acid resistant work clothes< (4) fire resistant work clothes< (5) heat insulation work clothes< (6) ventilated cooling work clothes< (7) water cooling work clothes< (8) radiation proof work clothes< (9) raincoat for labor protection< (10) ordinary work clothes the wearing requirements of protective clothing for operators on power construction site are as follows: (1) operators must wear work clothes during operation (2) when operating the rotating machinery, the cuff must be tightly fastened< (3) personnel engaged in special operations must wear protective clothing< (4) the welder's work clothes should be made of white canvas< There are many kinds of protective shoes, such as leather safety shoes, anti-static rubber soled shoes, rubber surface anti smashing safety shoes, insulated leather shoes, low-voltage insulated rubber shoes, acid and alkali resistant leather shoes, acid and alkali resistant plastic molded shoes, high-temperature protective shoes, stab free shoes, welding protective shoes, etc. 1t should be selected and used according to different workplaces and contents insulation boots (shoes), welding protective shoes, acid and alkali resistant rubber boots and leather safety shoes are commonly used in power construction. The requirements for insulating shoes are as follows: (1) they must be used within the specified voltage range (2) the rubber parts of insulating shoes (boots) are not damaged, and preventive tests are carried out every six months (3) it should not be used as auxiliary safety appliance under the conditions of immersion, oleic acid, alkali, etc< 5. Protective gloves most of the work on the construction site is done by hands, which determines that hands are often in danger. The safety protection of opponents mainly depends on gloves when using protective gloves, it is necessary to analyze the workpiece, equipment and operation conditions, and select gloves made of appropriate materials and easy to operate, so as to protect the operation. 1t is not easy to use protective gloves for operations requiring fine adjustment, especially for operators using drilling machine, milling machine, conveyor and parts with pinch risk, if they use gloves, they may be entangled by machinery. Therefore, personnel engaged in these operations are strictly prohibited to use protective gloves there are several kinds of protective gloves commonly used on the electric power construction site: (1) labor protection gloves. 1t has the function of protecting hands and arms. Operators usually use this kind of gloves when they work< (2) insulating gloves for live working. Select appropriate gloves according to the voltage, check the surface for cracks, cracks, sticky, brittle and other defects, and prohibit the use of abnormal gloves< (3) acid and alkali resistant gloves. 1t is mainly used for gloves when contacting with alkali< (4) rubber strain gloves. The gloves are mainly used for contacting mineral oil, vegetable oil and various solvent oil of fat cluster< (5) welding gloves. For the protective gloves worn in the electric and fire welding industry, the leather or canvas surface should be checked to see if there are any defects, such as rigidity, thin file, holes and so on. 1f there are any defects, they are not allowed to be used. Gloves should be of sufficient length and wrists should not be exposed< 6. 1nspection methods of common safety protectors common safety protectors must be carefully inspected and tested. Whether the safety net has debris, whether it is damaged by attachments or damaged by lifting objects. Whether there are cracks after the underpants of safety helmet are hit by falling objects. Check the safety protection equipment regularly, and socialize according to the requirements (1) safety helmet: 3kg steel ball, falling vertically from 5m height, will not be damaged. 1n the test, a half head model shall be made of wood, and the inner buffer elastic belt of the safety helmet shall be fastened and placed on the model. This method can be used in the test of safety helmet made of various materials. The inspection cycle is once a year (2) safety belt: according to the national regulations, the factory test is to take an object with a load of 120kg, impact the safety belt from the 2-208m elevated, and the parts are qualified if there is no damage according to the actual situation, the construction unit can
