Health and Safety (K3) in ICT

Health and Safety (K3) in ICTAdvancement of science and technology can improve the welfare of human life can be misleading result dadisisi other civilizations and cultures are created. Thus, mastering the technology (computers) that synergized with the internet making man can conquer the world. However, as device technology, the computer can also cause health problems for users.A. Computers and HealthOn the one hand, the success / progress of science and technology can improve the welfare of human life, and on the other hand can be misleading and devastated and meluluh-lantahkan result of civilization and culture that has been created. One of the technologies in question is the computer. A work of genius Howard Aiken in 1944 and known as the Harvard Mark I Computer type / Aikens Digital computers.Computers are a series of electronic equipment that works together, can do the job automatically through a series of instruction / programs provided to the computer, data processing devices into information through a certain process.Computer as a product and as technology has advantages such as:1) able-access quickly and precisely,2) generate information from past data,3) capable of processing very large data into information4) capable of storing so much data (up to giga bytes),5) capable of importing and exporting data designed specifically.With the presence of these technologies work processes becoming obsolete conventional society. The sophistication of these products can not be denied as if remembering all segments of life untouched by this technology products from the milking activities until the war strategy. This product is able to overcome the barriers of space and time faced by humans. Thus the teacher is not the only source of learning for students.Multimedia computers and the Internet as the medium was (in 1969 and popular in 1992) seemed to make the world just a fist. Philosophy that mmenyatakan who controls the information then he will rule the world.Thus the master computer that synergized with the internet making man can conquer the world. However, as device technology, computers also pose health problems for its users. For that there are procedures in order not to negatively impact the health and salvation work.B. Health and Safety (K3)Health and Safety (K3), is an aspect that must first be a concern any conduct of any activity, including when working with computers. Research has revealed that working with computers can mnyebabkan health problems and even safety. Hence, K3 is an aspect that should be a concern when working with computers.The use of computers today increasingly widespread, not only used at the office, office, research institutes, universities, and schools, but also have used home-households to help with daily activities. Nonetheless, aspects of K3 not a concern of computer users.Although many of the benefits gained from the use of computers, but not many are aware of the impact or issues arising from the use of computers. The issue in question here is the old diseases continuously.a. The research has been done to conclude that computer users can suffer headache, muscle aches, and bones, especially the shoulder, wrist, neck, back, waist and bottom.b. In addition, the use of computers can still develop other diseases such as tingling, body swelling, stiffness of limbs, kidney pain, red eyes, watery eyes, pain, and even visual disturbances.Body position, the position of computer equipment, room lighting, and environmental conditions greatly affect kesehtan, salvation, and comfort when working with computers.In terms of safety, should be aware that the computer used to have electricity connected to high voltage. So with that have attempted to prevent the risk of electric shock. For it must regulate the electric wires in such a way that avoid electric shock, also must Noting the cables from the possibility of short circuit can cause fire and damage to computer equipment.Some things you can do to avoid the risk of working with computers are as follows:1. Adjust body position when working with computers so feel safe.2. Adjust the position of the device and the computer room so that it gives a sense of comfort.3. Eat, drink and rest enough. Do not hold your pee resisted because it was too engrossed in working with computers.4. Move body to decimate the occasional muscle tension and mind. Sports ragalah regularly.5. Every now and then switch the view to the outdoors for relaxation of the eye.1. Adjust the position of the BodyThat the position of the body when working denagn very influential on the health of your computer. By knowing the position of the body are eligible K3, then the computer can adjust the position and support in order to provide comfort.1.1. Head and neck positionAt berkeraja with computers, the position of the head and neck should be upright with his face directly kelayar monitor. The neck should not be bent or mengadah as this can cause pain in the neck.1.2. Position BackGood back position when using the computer is back upright position, not tilted to the left or right, do not bend and do not lean too tilted back. To get a good back position, should be supported with a good seat and comfortable.1.3. Position ShouldersA good shoulder position is the position of the shoulder is not too elevated and not too far down. When the muscles in the shoulder is still tense, this means that the position of the shoulder is not correct.1.4. Arm and elbow positionA good arm position is apabial can type and use the mouse comfortably. Each person has their own comfortable position. A good arm position is when the hands are next to the body and the elbow at an angle greater than 90 degrees.1.5. Leg PositionAt the time of working with computers, the foot should be placed on the floor or a footrest with the foot touching the floor and elbows which makes an angle of not less than 90 degrees.2. The parts of the information technology that is harmful to health and safety2.1. MonitorComputer monitors typically use a picture tube (CRT) which can cause the intensity of light emitted by the monitor high enough to be accepted by the human eye retina.Therefore, part of this device should have anti-radiation screen, in order to avoid eye damage due to the radiation beam of light from the computer.To reduce the complaint to the eye, there are several screens that need attention.a. Should put the monitor in such a way the room so that the screen does not reflect light from other light sources.b. Letakanlah monitor lebiih hoizontal lower than the eye line, so as not mengadah or down.c. Arrange light of the monitor so as not too bright and dark.d. Frequently wink to keep the eye is not dry. Every now and then looked away from the room.2.2. CPU (Central Processing Unit)Part of these computer devices may not directly come into contact with hands (wet) because electricity is there on the CPU can electrocute people.a. Wet hands either by water or sweat may not directly come into contact with the CPU.b. Existing power flow on the CPU can cause stun.2.3. Computer CablesPart of these computer devices should be avoided from the water, because it can cause a short circuit. This can result in shorted electrical circuit that could cause a fire.2.4. KeyboardResearch has shown that the position of the keyboard is one of the factors causing sore muscles and joints. Causes of muscle and bone pain caused by the keyboard is the use of certain radius for a long time. This is especially when playing games.Avoid spilling water on the keyboard that can lead to:a. Keyboard Hange / damagedb. Keyboard kuningn mossy yellowish and not beautifulc. Short circuit
