Common hazards encountered by computer technicians and users A hazard is a situation in the workplace that has the potential to harm the health and safety of people or to damage plant and equipment. The situation could involve a task, chemical or equipment used. Hazard management is a continuous process that can be used to improve the health and safety of all workplaces. TYPES OF HAZARD (URL: https://youtu.be/vauNWk02ahc by Dr. Salah Rammal “Take care when using Computer”) Physical Hazards One of the most common physical hazards involving computer technicians is cables running across the floor. If someone trips, falls, and hurts himself because of a cable you ran across the floor, someone (you, your employer, or your customer) has a serious legal negligence problem. If you need to temporarily run a cable across the floor, place a Danger sign similar to those "wet floor" signs used by cleaning services. Mechanical Hazards When working on electronic equipment, ask yourself "Is there any way this equipment could hurt me?‖. You might stick your hand in a printer and suddenly the paper feed arm moves, feeding not only paper through the printer, but a piece of your finger too. You might move your hand past a computer chassis and lose a chunk of flesh because it is razor sharp. When working on electronic equipment always be alert to any possibility of being hurt by moving parts, hot components, or sharp edges. Chemical Hazards. There is a wide array of chemicals used with electronic equipment. There are display cleaning chemicals, keyboard cleaning chemicals, compressed gas dirt and dust removers, and many cleaning solvents. Some of these chemicals can be harmful if accidentally swallowed, get on bare skin, or get in eyes. Before using any chemicals for electronic equipment always read the warnings and instructions on the label. Ergonomic Hazards are physical conditions that may pose risk of injury to the musculoskeletal system, such as the muscles or ligaments of the lower back, tendons or nerves of the hands/wrists, or bones surrounding the knees, resulting in musculoskeletal disorder (MSD).
