It is understood that arm injuries are common in the production process, accounting for about 25% of the total number of industrial injuries. The more common arm injuries in the production process include: fire and heat, electricity, chemicals, impact, cutting, abrasions, and infections, among which mechanical damage is more common, such as impact, cutting and so on. However, the consequences of electric injury and radiation damage are even more serious, and some can lead to death. Lack of arm protection leads to casualties At the beginning of September, when four workers in Nanning, Guangxi, changed their advertising drawings on the outer wall about 8 meters high, three people suddenly received electric shocks and one of them was stunned. According to the analysis, the reason for the worker's electric shock was probably the iron leakage of the advertising signboard. The reason why another man avoids being charged is that he wears insulating gloves. On September 5, an air conditioner worker in Jinan, Shandong Province was accidentally charged during the installation of air conditioners and died after being rescued. His co-worker said that it was possible that a wire lead was leaking at the time. The ambulance staff stated that he did not see any protective equipment worn by the worker. On the morning of September 6, when a factory worker in Yantai City of Shandong Province lubricated the turbine, his glove was suddenly caught in the gear, causing the worker’s right hand to be squeezed by the gear. Fortunately, the worker immediately pulled the switch and pulled the worker's hand out. At the same time, he took ice cubes, wrapped his fingers, and rushed to the hospital to get his bones. The above three examples are accidents happening around us, and such accidents are not uncommon. If employees can't wear hand protective equipment as required, or if they don't dress properly, it may lead to casualties. Multiple product protection arms Arm protection generally refers to the protection of the opponent and the protection of the arm. Hand protection mainly uses protective gloves. In order to protect the hands below the elbow (mainly below the wrist), the hands are protected from injury, including live working insulating gloves, acid and alkali resistant gloves, welder gloves, rubber oil resistant gloves, waterproof gloves, anti-virus gloves, and anti-virus gloves. About a dozen kinds of electrostatic gloves, anti-cut gloves and so on. Protective sleeves are used for the protection of the arm to avoid injury to the forearm or the entire arm, including radiation protection sleeves and anti-acid sleeves. There are so many types of arm protection products. Can our workers correctly understand their usefulness and wear it properly? Worker: Gloves are for your own good In order to understand the views of employees in various industries on gloves, the reporter interviewed grassroots workers on this issue. Shen Jiansheng from Anhui Power Construction Company II introduced the overall situation of their company to reporters. In the power construction industry, most of the work involved are welders, electricians and construction workers. Welders use special gloves for welders, leather, white, to prevent burns; live work types use two types of insulating gloves for live work, one is low pressure gloves, mainly for 220 volts and 380 volts, one is High-pressure gloves are mainly used for voltages above 10,000 volts. The rest of the construction workers use cotton gloves and cloth gloves. They are mainly used by workers to protect their hands during the handling of angle iron channels and during construction, avoiding crushing and scratching. The replacement of gloves depends on the type of work and the degree of wear of the gloves. Generally, the welders' gloves can be used for 1 to 2 years. Because the wear is severe, the construction worker can change two pairs of yarn gloves one month, and the cloth gloves can generally use one. Winter or two months. Ma Yanning, from Ningxia Dam Power Generation Co., Ltd. She said that the company is a firepower plant and mainly engaged in three majors: steam turbines, boilers, and thermal engineering. Therefore, the gloves they choose are mainly for insulation and anti-oil pollution. Generally, they are yellow rubber gloves and are used more often in electrical and boiler applications. The other is canvas gloves, thread gloves and leather gloves. Xue Jun, an employee of the Steel City Enterprise Corporation in Panzhihua, Sichuan, said that the entire Panzhihua Iron and Steel Company has lathes, locksmiths, welders, and riveters, and uses different gloves according to the type of work. Steel gloves, iron making, and other heavy manual use of palm gloves, only separate the thumb and four fingers, made of at least 3 layers of canvas, with good heat resistance. There are also five-finger gloves, more convenient and flexible. Anqing Petrochemical Asset Management Co., Ltd. Zhan Qingwu told reporters that because it is the petrochemical industry, the company mainly uses line gloves, cloth gloves and cloth gloves. The main purpose is to prevent scalding and prevent oil. When it comes to the use of precision instruments, it is necessary to wear gloves to protect delicate instruments. Also from the petrochemical industry is Yin Qihao, secretary of the office manager of the Qilu branch of Sinopec, and he said that petrochemical companies use more gloves or leather gloves, mainly for the purpose of anti-corrosion, high temperature, and anti-scald. At the same time, he also mentioned a kind of latex gloves, that is, the gloves that need to be worn during the sampling and analysis work in petrochemical companies' laboratories. The cuffs are relatively long and they reach the elbow, and they mainly act as anti-corrosion and acid and alkali resistance. He said that the gloves of the company's operators are issued monthly according to regulations, and at the just-convened workers' congress, there are also opinions that workers should increase the number of labor supplies (including gloves) to grassroots operators. During the interview, the reporter found that different types of work use different gloves, and most companies can issue gloves as required. Employees can also wear gloves as required, because wearing gloves has little effect on labor efficiency, and they can avoid oil pollution, corrosion, and mechanical injuries. Workers generally recognize the benefits of wearing gloves. Fines are the most common method of punishment Arm protection products are so important, but workers are still not aware of their importance. Hands protection is less important than the lack of head protection that can cause fatal injuries. According to the information, some workers cannot use hand protection products correctly, especially for small businesses and small workshops. The reporter found in some electrical welding repair points that many workers lacked the necessary protective measures and awareness of protection when they were charged, and did not wear protective gloves. They also said: "It does not matter, electricity can not." This situation is much better in large enterprises. Shen Jiansheng said that overall, welders use gloves best and most standardized because of the danger of welding. He further explained that in their Anhui Power Construction Company, what kind of gloves are used in all types of work has very detailed and clear provisions. If you do not wear gloves in accordance with the regulations, you should generally impose a fine of 200 yuan. Anqing Petrochemical Asset Management Company's Zhan Qingwu also said that their gloves are all purchased by the Department of Safety and Security. Wearing gloves is part of the labor protection dress. If it is not worn as prescribed, it will be punished according to the provisions of the Economic Responsibility System, and the monthly bonus will usually be deducted. Gloves learn big Gloves can protect the lives of workers. Xue Jun told reporters about such a case: On May 31, 2005, Pangang’s cold-formed steel mill rolling plant Zhou visited the production line site and found high-frequency output copper plates and cooling next to the unit's welding transformer. Water hose insulation tube contact, and burning phenomenon, he subconsciously stretched his left hand want to move the insulation sleeve, unexpectedly not close to the contact, it was high frequency output electric copper discharge injury, resulting in left hand and right foot electric injury . If he had a stronger sense of safety at that time and put on insulating gloves to operate, this accident would not happen. However, gloves can sometimes hurt employees. Shen Jiansheng, for example, said: When construction workers use aircraft drills, pistol drills, etc. to drill to the angle iron, it is strictly prohibited to use yarn gloves. This is because the angle iron chips drilled during drilling need to be cleaned up. If the workers use yarn gloves at the time, the cotton yarn on the gloves is easily twisted by the drill and twisted into the drill hole. Hand. Such things have happened and are not rare. Therefore, Shen Jiansheng said that he would not be able to wear gloves when cleaning iron scraps. However, he added: “Because the weather in winter is particularly cold and there are a lot of oil stains and rust on the angle irons, many workers will wear yarn gloves in violation of regulations.†Shen Jiansheng said: “If there is a suitable glove to replace yarn Gloves, such an accident will be effectively avoided. Unfortunately, the situation is as if there is not yet a suitable glove to use in this kind of workplace." Employees Need More Humanized Gloves In the interview, the reporter learned that employees are generally able to wear gloves in a standard manner, but there are also some suitable gloves for labor choices. According to the reporter's understanding, in foreign countries, the classification of gloves is very detailed, and what kind of gloves are used in what kind of situations is very clear. Domestic follow-up is also taking place, but this road will take some time to come. On the standard website of the Industry Development Department of the National Development and Reform Commission, there are nearly 200 pieces of information about the standards and test methods related to gloves. How small gloves can better protect the safety of workers is a great learning. According to the process of China's individual protective equipment standard system, it is currently in the stage of revision and formulation of standards. We have reason to believe that in the future there will be more and better gloves for employees to use. Classification of gloves Insulating gloves for live working Refers to an insulating glove that the worker wears on his or her hands when carrying out live work on electrical equipment with a voltage of 10kV or less (or a DC electrical equipment of a corresponding voltage class). Its product model, appearance size and technical requirements must comply with the "General technical conditions for insulating gloves for live working". Gloves must have good electrical insulation properties. At the same time, it needs good tensile strength and elongation at break, as well as puncture resistance, aging resistance, flame resistance, and low temperature resistance. Acid and alkali resistant gloves It is to prevent the acid-alkali injury hand protection products, its quality should comply with the "acid (alkaline) gloves" provisions. Gloves are not allowed to have defects such as blooming, brittleness, stickiness, and breakage. The non-leakage property of the glove means that it must be air-tight, and under a certain pressure, no leakage occurs. Such gloves can be divided into rubber acid and alkali resistant gloves, latex acid and alkali resistant gloves, plastic acid and alkali resistant gloves, and dipping acid and alkali resistant gloves according to the material. Waterproof gloves, anti-virus gloves can be used instead of acid and alkali gloves. Oil resistant gloves These products are made of nitrile rubber, chloroprene or polyurethane to protect the skin of hands from various skin diseases such as acute dermatitis, acne, folliculitis, and dry skin. Cleft palate, pigmentation, and nail changes. Welder gloves To protect against high temperatures during welding, molten metal, sparks, and personal protective equipment. Made of bovine, hog tanned or two-layer leather, it can be divided into two-fingered, three-fingered and five-fingered fingers depending on the type of finger. Welders have strict appearance requirements. The first grade product requires a uniform thickness, fullness, softness, and elasticity. The leather surface is fine, uniform, firm, and consistent in color, with no greasy feel. Secondary products: leather body lacks full elasticity, leather surface rough hair, a slight shade of color. Anti-vibration gloves Used in contact with vibration, such as in the forestry, mining, construction, transportation and other departments with hand-held vibration tools (such as chain saws, rock drills, etc.) to prevent vibration caused by occupational diseases, "white finger disease" personal protective equipment. Anti-vibration gloves in the structure, mainly in the palm of the hand to add a certain thickness of foam, latex and air sandwich to absorb vibration. The thicker the liner thickness, the more air it contains, the better the damping effect. However, if the palm and fingers are too thick, it will affect the operation. Flame retardant gloves The traditional fire-retardant flame-retardant gloves are made of asbestos materials, which are divided into two-finger and five-finger styles. They are available in large, medium and small sizes. Because asbestos fiber is irritating to human skin, it is rarely used at present. Nowadays, flame retardant fire-retardant gloves are generally made of fire-retardant canvas or other fire-retardant flame-retardant fabrics, which are suitable for use in smelting furnace fore work or other types of furnace work. Anti-static gloves Contains conductive fiber woven composition. The other is long-fiber stretch acrylic knitted gloves, and then apply polyurethane resin on the palm part, or paste polyurethane resin on the fingertips or the surface of the glove has a polyethylene coating. The gloves containing conductive fibers cause the static electricity accumulated on the hands to quickly disappear. Polyurethane or polyethylene coated gloves are mainly not susceptible to dust and static electricity. These products are mainly used for the assembly of weak currents, precision instruments, product inspections, electronic industry, printing, and inspections by various research institutions. Protective gloves should be selected according to the protective function 1. There are many types of protective gloves, which should be selected according to the protective function. First of all, you should clearly identify the object of protection and then carefully select it. Such as acid and alkali resistant gloves, resistant to strong acid (alkali), resistant to low concentrations of acid (alkali), but resistant to low concentrations of acid (alkali) gloves can not be used to contact high concentrations of acid (alkali). Remember not to misuse it to avoid accidents. 2. Waterproof, acid and alkali gloves should be carefully inspected before use, observe whether the surface is damaged, take a simple approach is to breathe in the gloves, hand tightly cuff, observe whether the leak. Leakage can not be used. 3. Insulating gloves should be regularly tested for electrical insulation performance and cannot be used if they do not meet the requirements. 4. Rubber, plastic and other protective gloves should be washed and dried after use. Avoid high temperatures during storage and sprinkle talcum powder on the product to prevent adhesion. 5. Contact with strong oxidizing acids such as nitric acid, chromic acid, etc., due to strong oxidation can cause protective gloves brittle, discoloration, early damage. High concentrations of strong oxidizing acids may even cause burns and should be observed. 6. Latex industrial gloves are only suitable for weak acids, low concentrations of sulfuric acid, hydrochloric acid and various salts, and must not be exposed to strong oxidizing acids (nitric acid, etc.). In the power telecommunications industry, workers encounter various types of live operation. According to the actual operating voltage to select the appropriate electrical insulating gloves, and in actual operation, should use electrical external gloves and electrical insulating gloves together to better protect the puncture and tear hazards. Before and after each use of electrical insulating gloves, the necessary checks should be carried out to ensure the safety during use. Protective sleeve Protective sleeves are used to protect the hands of the arm. There are: 1. Asbestos radiation sleeve: used in high temperature furnaces and other workplaces. 2. Aluminum film insulation sleeve: used in high temperature furnaces and other operating environments with strong radiant heat. 3. Anti-acid and alkali-coated sleeves for blankets: used for contact with water, acid and alkali, dirt, etc. 4. Plastic acid and alkali resistant sleeves: used for contact with water, acid and alkali, dirt, etc.
Workers need a pair of gloves
Hands play an important role in the production process. With these hands, we can engage in all kinds of labor, and we can only say that "the two hands have created the world." However, the arm is also very vulnerable to injury, electric shock, acid and alkali corrosion, mechanical injury, etc. may cause injury to the arm, and may result in severe disability or even death. How to avoid the worker's arm from being hurt in the work, arm protection supplies will come in handy.
