Office Ergonomics Office Ergonomic Chair Office Ergonomic computer Desk Office Lighting. KEYSWORDS


Ergonomics is becoming a commonplace word, especially in the office environment. By itself, the word ergonomics refers to the study of designing objects, such as chairs, keyboards, and workstations, to be well adapted to the form of the human body. Ergonomics can be applicable in many jobs, but it is growing more and more important in the office environment. The terms computer ergonomics and office ergonomics are pretty much interchangeable. They refer to using well-designed ergonomic chairs, desks, keyboards, etc. -- basically everything you use when working at the computer -- that promotes good posture and good work habits. INTRODUCTION


Good home and office ergonomics is very important because we are turning into a society that spends more and more hours working and playing at the computer. Sitting at poorly designed workstations can contribute to problems such as Carpal Tunnel Syndrome and repetitive stress injuries (RSI). Bad ergonomics can also cause back and neck pain, frequent headaches, and other related health issues. APPLICATION OF ERGONOMICS


Now a days Ergonomics is very useful subject matter in working places. Specially the ergonomics that is applied in office is called office ergonomics .Lighting factor,Furnitures,Vidual display terminal are the some ergonomic factors which have to be took consider in office Ergonomics. For making well defined ergonomical office we must maintain all ergonomic factors. OFFICE ERGONOMICS


ANTHROPOMETRY Anthropometry, in physical anthropology , refers to the measurement of the human individual for the purposes of understanding human physical variation. Today, anthropometry plays an important role in industrial design , clothing design, ergonomics and architecture where statistical data about the distribution of body dimensions in the population are used to optimize products. Anthropometric studies are today conducted for numerous different purposes. Academic anthropologists investigate the evolutionary significance of differences in body proportion between populations whose ancestors lived in different environmental settings.

In an ergonomic chair, you want something that is highly adjustable. Not only should the chair adjust up and down (you need to be able to sit with your feet comfortably flat on the floor), but the back rest should track your position and adjust accordingly (avoid chairs that lock into position). The seat pad of the chair should be contoured to allow for even distribution of your weight. Good ergonomic chairs come with noticeable but comfortable lumbar (lower back) support. The chair's arm rests should also be adjustable. Good ergonomic chairs won't make you scrunch your shoulders up in order to place your arms on the rest. OFFICE ERGONOMIC CHAIR


Back pain is one of the biggest troubles for people who remain seated in one position for a long period, such as computer operators. It is caused by remaining static in a chair for a long time. People in sedentary jobs with poorly designed chairs suffer more back pain. You can say goodbye to back pain with a purchase of an ergonomic chair. This type of chair will give you a perfect posture, necessary for maintaining the proper alignment of the spine. Also make sure you take numerous breaks throughout the day; experts recommend a 2-3 minute break every half hour. Get up and stretch during your break. Look away from the monitor. Proper seating in a well-constructed ergonomic chair can help reduce fatigue and discomfort, increase blood flow, reduce the risk of injury, and increase productivity. WHY NEED ERGONOMIC CHAIR?


To help you to choose an ergonomic office chair, you should check whether the chair will meet the following criteria: Does the seat pan feel comfortable and fit your shape? When you sit back against the lumbar support, does your ergonomic office chair give you ample space for hip room? While sitting, can you easily adjust the height of the armrests and can you move the armrests closer together or further apart? Can you easily move the arms out of the way if you need to do this? HOW TO CHOOSE GOOD ERGONOMIC CHAIR


People often think about ergonomic chairs, but they don't realize a good computer desk is part of the picture. A desk must fit well into your work space, but it should fit you well, too. It may also incorporate CPU holders, writing areas, and speaker platforms. Most of these workstations are highly adjustable to conform to the needs of the individual. OFFICE COMPUTER DESK


Choosing wisely when it's time to shop for a computer desk will keep we from having to buy accessories like keyboard trays, foot rests, and monitor risers later. We may consider a height adjustable computer desk. It's important that our keyboard be at the right height; we should never have to reach up or extend our arms away from our body in order to type. Look for a desk with a keyboard drawer or tray and enough leg space for our chair to fit under it. Monitor height is an important part of computer ergonomics, so make sure you think about where your monitor will fit when you buy a desk SELECTION OF OFFICE COMPUTER DESK


Good office lighting is important for computer work. Bad lighting can strain your eyes and cause headaches. It can also encourage poor posture as you lean close to your work or the computer monitor. This can contribute to repetitive stress injuries RSI. OFFICE LIGHTING


Don't put lights anywhere that will produce glare on our monitor. Also watch out for glare on reflective surfaces such as class computer desks and the like. Make sure your monitor screen is well lit, but also consider lighting the wall/space behind your computer to avoid pockets of darkness that contrast with the brightness of the monitor. Consider adjustable sources of lighting near work areas. Consider mixing colors in your lighting scheme (i.e. incandescent and halogen) to offer more for variety for our eyes. SUGGETIONS FOR GOOD OFFICE LIGHTING

Case study #1(Head’s room of I.P.E Dept.):

After analysis we are got some problems in the office room. Overall room space is small for existing arrangement. Around the space of chair is small that create problem for movement any direction. The left corner of the room is congested enough. The left window hold a lot of wire connection that may be create problem. The daylight is not sufficient to work. There may problem in ac. Case study #1(Head’s room of I.P.E Dept.)

Case study#2(office room of I.P.E dept.):

After analysis we got some problems: There are illumination problem. The functional forward reach of table is not enough for work. The chair is not moveable so that the work of computer is done difficult. there are not wrist rest, elbow rest, and footrest. Case study#2(office room of I.P.E dept.)


In this analysis we became familiar with the term Office ergonomics .Office ergonomics is a design of office in such a manner the every affecting factors are in well condition. We have discussed two case study about the office ergonomics.1 st case was about office of our head of Dept. and 2 nd one was about an ideal office. There are some ergonomical problems(lighting problem, there is no ergonomic chair, ergonomic computer desk etc.)for solving these problems we must keep there ergonomic chair ,desk and we must maintain lighting in office.
