Fire and explosion protection in power stations is a problem worthy of attention. Among them, explosion accidents caused by electric power are relatively common and harmful accidents. Therefore, when workers are working in power stations, wearing insulating protective shoes can reduce the number of accidents caused by electricity casualties. A series of dangerous accidents.
There are many equipment in the power station, and many of the equipment are live. Wearing safety shoes with insulating function can reduce the possibility of electric shock during equipment maintenance and repair. Because insulating safety shoes are suitable for environments with more current, they can isolate the current from passing through the human body through the contact point, and are safety shoes to prevent electric shock to the human body.
Safety shoes, the shoe fabric is made of suede, which is hygroscopic, breathable, and the fabric is soft, shiny and comfortable. The sole adopts the continuous injection molding process. The solid sole surrounds the shoe body and fits seamlessly. There are no stitches to reduce friction and wear.
During maintenance and repairs in the power station, the operators wear insulating shoes and gloves, and wear safety shoes with insulating and anti-smashing functions in complex work scenarios. This is not only a good labor safety protection, but also a responsible performance for themselves. .
Anti-slip safety shoes are generally divided into two situations?
Usually, the outsole materials of insulating shoes, electrician shoes and anti-smashing safety shoes are oil-resistant, non-slip, wear-resistant, pressure-resistant, waterproof, elastic, and drop-resistant. Heat resistance, impact resistance, easy to fit the foot shape, not easy to deform after setting, heat preservation, easy to absorb moisture, etc. These are also the basic functions of safety soles.
Safety shoes with safety functions are essential products for safe production. Therefore, the anti-skid function of our safety shoes must be good. But in fact, there are many factors that affect the anti-skid safety of insulating shoes, such as sole material, ground hardness, dry humidity, flatness, sole pattern, structure, etc.
Anti-slip safety shoes can basically be divided into two situations. The anti-skid effect on dry ground is often referred to as dry anti-skid. The anti-skid effect when there is water on the ground is called wet anti-skid. For the anti-skid effect, the anti-skid function of the safety sole needs to design different shoes and soles according to the requirements of different environments.
At present, labor insurance shoes in my country can be roughly divided into: protective toe safety shoes (ie, anti-smashing labor insurance shoes, anti-smashing labor insurance shoes), puncture-proof labor insurance shoes (also known as puncture-resistant labor insurance shoes), and electrical insulating shoes (that is, we Usually called insulating shoes), anti-static labor insurance shoes, acid and alkali resistant anti-static labor insurance shoes standard GB12011-2009, mainly used for electricians, electronic operators, cable installers, substation installers, etc. This kind of shoes can only be worn in an operating environment with a power frequency voltage of less than 1KV, and the upper must be kept dry, and must not be in contact with sharps, high temperatures and any corrosive substances. If the upper sole is corroded or damaged, it cannot be used. Immediately replace with new electrically insulating shoes.
The standard for puncture-resistant labor insurance shoes is GB21148-2007. This standard requires that the puncture resistance strength must be greater than or equal to 1100N to qualify as a qualified product. It is suitable for mining, fire protection, construction, forestry, cold work, machinery industries, etc.
Anti-static labor insurance shoes standard: GB21148-2007, anti-static shoes are worn more in some chemical plants, gas stations, liquefied gas filling and other industries, because these industries belong to flammable places. Wearing anti-static shoes can eliminate the accumulation of static electricity in the human body, and the insulation resistance is kept between 100KΩ-1000MΩ, but when wearing these shoes, you cannot wear thick woolen socks or use insulating insoles, and should be matched with anti-static clothing; you should also wear 200 The resistance value test of shoes should be carried out within hours. Only the resistance within the specified range can be used as anti-static shoes, otherwise it cannot be worn as insulating shoes.
The implementation standard of acid and alkali resistant labor insurance shoes is GB12018-1989. The shoes are used in electroplating, pickling, electrolysis, liquid dispensing, chemical manipulation and other fields, but the concentration of acid and alkali operations in these fields is not too high; the shoes also cannot be exposed to high temperature, It should not be injured by sharp objects, and the sole should not leak. After wearing, it should be rinsed with water immediately and dried. It should not be directly exposed or dried in the sun.
Labor insurance shoes with safety functions are essential products for safe production. Usually, the outsole materials of insulating shoes, electrician shoes, and anti-smashing labor insurance shoes are oil-resistant, non-slip, wear-resistant, pressure-resistant, waterproof, elastic, and drop-resistant. Heat resistance, impact resistance, easy to fit the foot shape, not easy to deform after setting, heat preservation, easy to absorb moisture, etc. These are also the basic functions of safety soles.
Therefore, the anti-skid function of our labor insurance shoes must be very good. Don't you need to pay special attention to the basic functions? In fact, there are many factors that affect the anti-skid safety of insulating shoes, such as sole material, ground hardness, dry humidity, flatness, sole pattern, structure, etc. Anti-skid can basically be divided into two situations. The anti-skid effect on dry ground is often referred to as dry anti-skid.
sole
The anti-skid effect when there is water on the ground is called wet anti-skid. For the anti-skid effect, the anti-skid function of the labor insurance sole needs to design different shoes and soles according to the requirements of different environments. The uneven shading of the roughness safety insulation sole can effectively increase the actual contact area, thereby increasing the friction and improving the anti-skid effect.
The structure, thickness and depth of different shading, deformation and actual contact area with the ground are also different. The sole pattern design of insulating shoes and electrical shoes should consider not only the dry contact surface, but also the wet contact surface. In short, safety and labor protection The material and pattern structure of the sole play an important role in its anti-slip and anti-slip functions.
The quality of labor insurance shoes is directly related to the safety of people's bodies
The quality of labor insurance shoes is very important, because labor insurance shoes are directly related to the safety of people's bodies. Choose labor protective shoes according to the working environment, meet the most basic protective functions, ensure that the protective test meets the standards, and the manufacturer can provide the test report.
1. Choose the type of labor insurance shoes (anti-smashing / anti-puncture / acid and alkali resistance / high temperature resistance / non-slip safety shoes) according to different workplaces.
Among the five protective properties of An1 type, An2 type, An3 type, An4 type and An5 type of labor insurance shoes, the An1 level is high and the An5 level is low.
High-level labor insurance shoes have high technical indicators of pressure resistance and impact resistance at the front end, and good protection of toes. Therefore, the more likely the toes are smashed or crushed, and the more serious the injury is, the more high-level safety shoes should be used, and some toes may be smashed or crushed, and the degree of injury is unlikely. For serious operations, you can choose low-level labor insurance shoes, because high-level safety shoes are often expensive, bulky to wear, and poor comfort.
2. Choose labor insurance shoes with different prices, styles and materials according to your own needs.
Usually, injection leather shoes are new and lightweight, and the outsole is made of polyurethane material, which is wear-resistant and expensive; adhesive safety shoes are a traditional craft with a long production history, and the price varies according to their styles and materials;
The price of sewing tire sole safety shoes is relatively cheap, but the price of not the tire sole also varies depending on its style, material, etc.; in addition, injection safety labor insurance shoes and adhesive shoes are less breathable, and sewing safety labor insurance shoes are more breathable. Better, more comfortable to wear.
3. Confirm whether the manufacturer of the product has a state-issued industrial product production license (not required for imported goods) and a safety mark certification. On this basis, check whether the product has the manufacturer's name and address, production license number, safety mark certification number, production date, product standard number, whether it is accompanied by a product certificate and instruction manual, and also pay attention to check whether there are any signs on the shoes. Product name (or "toe protection"), shoe size and protection performance level. In addition, distributors should be required to show the test report of the batch of products and check the validity period.
4. Check the appearance quality. You can check whether the upper surface has any disability, different colors, heavy stitches, skipped stitches, broken threads, and uneven stitch size; whether the upper sole is open or loose; whether the sole is over-sulfur, under-sulfur, or sprayed with sulfur. ; Whether the inner package head is skewed, etc.
It is often heard that the soles of labor insurance shoes have rubber soles, PU soles, and what are the soles of beef tendons? And what are the advantages and disadvantages of using beef tendon bottom?
The bottom of beef tendon is relatively easy to identify. From the outside, it is light yellow and translucent, so it is named after beef tendon.
The materials of the tendon bottom are rubber and plastic, and the tendon bottom labor insurance shoes seen on the market are basically made of thermoplastic rubber (TPR). Therefore, it can be considered that the beef tendon sole is also a kind of rubber sole.
The advantages of beef tendon bottom are non-slip, soft and elastic. Compared with the rubber sole, the softness is better.
The disadvantage is that the non-slip of the beef tendon bottom is generally on the tile floor and epoxy floor, and it needs to be free of water and oil stains. On the water and oil surfaces, the anti-slip effect of the beef tendon bottom is greatly reduced. (It is recommended to use a special SRC-grade anti-skid bottom. Shanghai Aoxiang shoes have a variety of anti-skid bottoms, which can prevent slipping on water and oil surfaces.
It should be noted that beef tendon soles are not resistant to oil. If there are oil stains in the working environment, it is not recommended to use beef tendon bottom labor insurance shoes.
In the northern winter, the bottom of beef tendon will become hard and lose some of its softness after the temperature drops. If the temperature of the working environment is low, the use of beef tendon bottom is not recommended.
