Hand injury in work and its prevention

What kind of injuries are hands vulnerable to

hand injuries can be classified into physical injury, chemical injury, mechanical injury and biological injury. Among them, mechanical injury is the most common. The mechanical injury of hand can be divided into closed injury and open injury. The former can affect bones, joints and tendons, and sometimes nerves; The latter is more serious, which will cause massive bleeding and affect other parts, and the treatment is more complicated. The degree of hand injury varies greatly, depending on the factors and process of injury. The most common injuries at work are cuts and stabs. Mild cuts only damage skin tissue, severe cuts can damage other tissues, and even cause partial or complete amputation; The stab injury is more serious because there may be foreign bodies in the wound. The healing of open hand injury is closely related to the degree of hand smudging. Generally speaking, injuries in chemical plants, slaughterhouses, meat processing plants and leather products factories are prone to infection and other complications

due to the widespread use of high-pressure spray and spray equipment in modern industry, the accidents caused by injecting injuries in the hands increased significantly. This kind of situation can be seen in internal combustion engine, spray gun, grease injection gun, plastic injection molding machine and some special equipment for auto repair. 1f the spray does not strike the skin along the tangent direction, it will not lead to skin cracking. At the beginning, it is only stinging, and it is often ignored. 1t will not be serious until the pain is aggravated due to local ischemia

sometimes, even if the amount of ejecta is not large enough to cause local ischemia, after a few days, there will be thermal or chemical stimulation. As the spray contains solvents, it may cause systemic poisoning symptoms

hand burns can be caused by fire, red body, hot air flow, chemicals or electric shock. The degree of injury depends on the contact time, burn area and depth. Due to the frequent occurrence of such injuries, sometimes they can be very serious. Although there is no trauma, the skin damage caused by exposure to toxic, irritating or allergic chemicals can not be ignored. 1t is one of the three major ways of occupational poisoning

the measures to protect hands are as follows: first, when designing and manufacturing equipment and tools, it is necessary to give full consideration to safety protection and equip them with relatively complete protection measures. The second is to formulate and improve safety operation procedures reasonably and improve safety prevention facilities. For example, the dangerous parts of the equipment should be equipped with protective cover, the heat source and radiation should be shielded, and the handle should be equipped with reasonable hand tools. 1f the above measures can not effectively avoid the accident, the use of personal protective equipment can be considered. The protective equipment can be roughly divided into gloves, finger cots, hand pads, sleeves, elbow protection, etc

there are almost no jobs. The hand is like a delicate tool, with amazing power and flexibility, able to grasp, rotate, pinch and manipulate. 1n fact, the connection between hand and brain is the key to human being’s ability to do all kinds of high skilled jobs. However, if you ignore the basic safety rules at home or at work, your hands will have a big problem

no matter where you work or play, there are three types of hand injuries: traumatic injury after an accident, contact injury caused by exposure to toxic substances, and repetitive activity problems caused by overuse of a certain group of muscles

traumatic injuries include abrasions, lacerations (cuts), contusions, fractures and crush injuries. Traumatic injuries usually occur when machines and tools are used carelessly. Contact damage occurs when your hands come into contact with harmful substances, such as detergents or chemicals. Burns can also cause contact injuries. Repetitive movement problems occur in tasks that require long periods of repetitive hand use

identifying the risk factors and formulating relevant safety measures can reduce the chance of 500000 hand injuries every year. The chance of hand injury should be minimized, and hand safety requires collaboration. What we need to do is learn the basic safety rules and follow them

the occurrence of hand injury accidents is often caused by the hidden danger of accidents in the production work, and it is impossible to have accidents without reason. There are potential safety hazards in four aspects: human unsafe behavior, unsafe state of goods, adverse environmental impact and lack of management

the occurrence of hand injury accidents may be caused by the lack of safety awareness of the person in charge of the enterprise, the lack of pragmatism in safety work, the lack of conscientious implementation, the operator’s lack of rules and regulations, or the management confusion. The person in charge of the enterprise has not really implemented all kinds of organizational and technical measures of the state in the aspect of labor protection, there are behaviors of attaching importance to production and neglecting safety, and there is a serious absence of enterprise management, which leads to the imperfection or nihility of the safety management system; Even the production workshops and assembly lines of many enterprises have not established and improved the operation regulations, rules and complete safety protection measures, or even if there are safety operation regulations and rules, their management personnel just stay in words, make superficial remarks, deal with the inspection, and do not strengthen the safety production management. Many enterprises have old equipment, aging machines, inadequate maintenance, poor working environment and careless safety inspection; The safety education and training are not in place and formalistic. The employees work when they are not familiar with the safety operation procedures, rules and regulations, machinery and equipment, and only rely on their own knowledge to take risks or operate blindly. The employees are used to this kind of situation. They are paralyzed, indifferent and have no sense of danger, There is a fluke mentality, in order to save time and effort, disobeying rules and regulations, illegal operation, operational errors, resulting in hand injury accidents

recognize the risk factors

although enterprises consider protecting your hands from the risk factors, only you can prevent accidents caused by carelessness, such as misuse of equipment and materials, improper contact with corrosive substances, and overuse of a certain group of muscles. Before you use your hands, think about the risk factors. At this time, some common hand injuries, you should try to avoid in life

traumatic injury: there are potential risk factors everywhere – chains, wheels, rollers or gears, nails or serrated tools; Edge of cutter; Cutting, chopping and pressure; Pumping tools and pipes; Wires and plugs; Falling objects< How to prevent: use protective tools correctly and operate safely. Be alert, especially when two people are working on the same machine. Know the performance of the machine you are using. Keep the machine in the best condition, make sure that the power of the machine is turned off and stopped when repairing the machine contact injuries: organic solvents, acids, cleaning fluids, flammable liquids, and hundreds of other substances can cause hand tissue damage or burns. Some irritants can cause acute injury; Some are chronic injury caused by long-term exposure how to prevent: know what kind of gloves to wear at work; 1f you are not sure, ask others. 1n the work found hand protection problems, timely report. Understand the hazards of the substances you are exposed to; 1f suspicious, it should be found out immediately. Keep every substance labeled and develop the habit of reading labels repetitive movement problem: repeated use of hands for a long time, such as grasping or squeezing, may cause tendon or nervous system damage prevention of traumatic injury the main cause of hand injury at home or at work is carelessness. The best way to prevent it is to be alert to the risk factors. Understand the machines and materials you work with, and the safety precautions. Make sure that the machine is well maintained. Make sure that the power is cut off and the machine stops before putting your hand into the machine. Especially when working with others on the same machine. Keeping your work area clean helps prevent all kinds of injuries. Take off rings, watches and bracelets before you start work. 1f an accident occurs, seek medical attention as soon as possible to minimize the complications types of damage and its prevention friction injury: abrasion can be caused by rotary saw, flywheel, grinding wheel, belt and roller, or rough material abrasion is only the loss of surface skin. Damaged skin makes it easier for harmful substances and bacteria to invade. Keep protective gear in place. Wear appropriate gloves when necessary to ensure that the gloves will not be rolled away by the machine stabbing: stabbing can be caused by nails, thorns, fragments, fishhooks, staples, glass, disciples or toothed tools, sometimes shallow, sometimes deep enough to pierce the deep tissue of the hand. 1f the stab is not treated properly, it will become a potential infection site. Keep the working area clean, do the right work with the right tools, and use it correctly. Use screwdrivers, punches, drills and knives carefully cutting injury: cutting injury usually occurs when you use blunt force to cut hard, or when two surfaces contact in the tangent direction. Mild cutting only involves the skin. Deep cuts can involve nerves and tendons, completely damage part of the function of the hand, stay away from the blade, use a sharp retractable blade. Use gloves to protect against cuts and scratches. Be alert to cutting accidents in work contusion: when you fall, your hand will touch the ground, which may lead to contusion, or sudden over exertion. For example, during weight lifting, in contusion, the muscles and ligaments that keep the joint stable will be bruised, pulled or torn. Be careful when walking stairs, especially when carrying heavy loads. Timely report and repair damaged stairs, carpets or floor mats. Don’t use chairs as climbing tools fractures: fractures often occur in “hand traps”, such as wheels, rollers or inward rotating gears; Or a violent hand slap on a hard object may result in one or more bone fractures in a single injury. Tendons and ligaments are usually lost, leading to pain, swelling and congestion keeping the hand away. 1t’s safe to use devices that have fast rollers. Press stick is used to operate rotating and running machines crush injury: crush injury is usually caused by the sudden approach of two fixings of a heavy machine. 1t can also cause explosive or compressive force due to falling heavy objects and door overstocking injury, which can cause deep tissue congestion of the hand. Bones can also fracture. Watch out for falling objects or heavy objects that can cause hand damage. Keep hands away from moving parts prevent contact damage the two layers of your skin can protect you from microorganisms and infections, unless this barrier is damaged by irritants or burns. Keeping clean and careful is the best way to prevent contact damage. Keep hands clean and comfortable when there are potentially harmful substances, electronic equipment or combustible objects at work. Don’t wipe your hands with a dirty, greasy cloth. Wash hands with soap and warm water after work. Avoid using a chemical before it is specified< China labor insurance net
