Ergonomics is the engineering science concerned with the relationship and stresses between workplace tools and the people who use them daily.The objective of ergonomics – to improve efficiency of the work environment’s operation, by accounting for one’s size, speed, visual and audio acuity, strength or physiological stress like fatigue, perception, memory, and or speed of decision making. Tools and machines may range from office furniture and equipment to operating vehicles or gauges controlling industrial machinery, to determining the clarity of a character, the character’s height, color, and specification on video displays. Ergonomics consists of two main thoughts, task and equipment design. Ergonomic task design develops the way in which the ordinary worker utilizes their equipment while, the equipment design focuses on a logical effect, the physical design of the tool or the machinery itself. Ergonomics is also known as human-factors engineering, the science of designing products and work environments to maximize the safety, comfort, and efficiency, of the workers who use them. The ergonomist takes an empirical approach to the study of human and machine interactions and relationships. Ergonomists establish a clear understanding of how quickly workers react to changes within their work environments and how workers process information. Key considerations of the ergonomist are how humans move, what repetitive motions are used and what are the effects on the body, and what makes certain situations more stressful on the body. How can this stress be relieved? In many cases, little change is necessary to relieve work environment stress. It can be as simple as how you sit in a chair or how close your computer monitor is from your eyes or what type of support is available. Ergonomists design your toothbrush handle, office furniture, automobile interiors, and corporate environments.Ergonomics implies a work environment is safe and comfortable for the worker to perform the assigned tasks. Without an ergonomic workstation, there are risks of minor to major discomforts from nerve to tendon strain or damage. A non-ergonomic workstation may cause carpal tunnel syndrome. Incorrect sitting posture and reaching repetitively may cause injury to the upper and lower back or neck. Eyesight or headaches may even worsen with inappropriate lighting, monitor placement, or posture.Two approaches to ergonomics are reactive ergonomics and proactive ergonomics. Reactive ergonomics is acting in response to an issue that has already became a problem while, proactive ergonomics is to discover potential problems before they take place. Proactive ergonomics saves on work injuries, increases productivity, and individual organization. The effective application of proactive ergonomics in the workplace is an excellent way for an employer to investment in employees and cut back illness and injury costs. Ergonomic products are to relieve work related physical and mental stress/tension as well as for correcting a worker’s posture and physical support in turn, creating comfortable workers thus gaining higher workplace productivity.
