What is ergonomics? Ergonomics is the science of fitting the job to the worker. When there
is a mismatch between the physical requirements of the job and the physical capacity of
the worker, work-related musculoskeletal disorders can result. Workers who must repeat the
same motion throughout their workday, work in an awkward position use a great deal of
force to perform, repeatedly lift heavy objects or face a combination of these risk
factors are most likely to develop work-related musculoskeletal disorders. In this report,
I will outline the main factors in having a safe workstation. There are certain ways in
which you may choose an ergonomically correct chair. Does the seat feel comfortable and
fit your shape? When you sit in the chair the seat should be at least one inch wider than
your hips and thighs on either side. The seat should not be too long for your legs
otherwise it will catch you behind the knees or it will prevent you from leaning fully
back. Most ergonomic chairs have a seat with a front that prevents the seat from catching
you behind the knees. The seat should also be contoured to allow even weight distribution
and it should be comfortable to sit on. Is the seat chair height adjustable? The chair
should be adjustable so that you can adjust seat height while you are sitting on the
chair. Some chairs have a mechanical height adjustment (spinning) mechanism. Does the
chair have a comfortable lower back rest? Many chairs have cushioned lower back supports
that can be adjusted up and down and forwards and backwards to fit your shape. If the
chair has a fixed height lower back support and it feels comfortable when you sit back
against this then a fixed lower back support may be acceptable. When you sit back against
the lower back support is there space for hips? Insufficient hip room can make you sit too
far forwards on the seat so that you will not have enough thigh support. Does the seat
still feel comfortable after you've been sitting in it for 30 - 60 minutes? If the seat is
made from foam then continuous use can cause it to become deformed and then it will not
provide cushioned support. Insufficient cushioning and inappropriate contouring can cause
discomfort and hip and back fatigue. Is the tilt of the seat adjustable? In some
situations it can be helpful to change the tilt of the seat pan to help to maintain a
healthy seated posture. Does the chair have a 5-pedestal base? The chair should have at
least a 5-pedestal base with casters that glide freely over the floor surface. You may
also want to choose a chair that swivels easily. Do you need armrests on your chair? If
so, are the armrests broad, cushioned and comfortable? While sitting can you adjust the
height of the armrests and can you move the armrests closer together or further apart?
Keyboard in the ideal typing posture both static and dynamic muscle loads are minimized.
This posture is achieved when the keyboard is below seated elbow height and the keyboard
base is gently sloped away from the user so that the key tops are accessible to the hands
in a neutral posture. In this position the arms, shoulders, neck and back can relax,
especially during brief rest pauses. Also, in this slightly reclined sitting position the
low back rests against the lumbar support of the chair, the elbow angle is opened to
promote circulation to the lower arm and hand, the abdominal angle, and the palatial angle
(behind the knees) are opened to promote blood circulation. The feet rest firmly upon the
floor. Monitor Optical glass glare filters on computer monitors can reduce health and
vision problems related to computer glare and help boost productivity in computer users,
according to a new Cornell University study. After using a glass anti-glare filter, the
