According to the Oxford Dictionary, ergonomics is defined as the study of people’s efficiency in their working environment. We believe injury prevention is a joint responsibility between both employer and employee. Below are some basic guidelines to help you make your work environment efficient and decrease the risk of injury.
Seated Posture
Make slight changes to the way you are seated throughout the day.
Stretch on a regular basis.
Keep your feet flat on the floor (or footrest) with knees bent at 90 degrees. If your feet do not touch the ground, use a footstool or pillow under your feet so your knees are at a 90 degree angle.
Do not cross your legs or ankles.
Your backrest should support the natural curve in the lower back (lumbar) area.
Your hip-torso angle should be in the 90 to 120-degree range.
Have your arms come straight down from the shoulders, elbows at 90 degrees and should be relaxed. If needed, place pillows under your buttocks or get a taller chair so your arms can be at a comfortable 90-degree angle.
Keyboard
Place the keyboard on a stable, level surface directly in front of you.
Hold wrists straight while typing
Adjust the keyboard to fit your hands, which may mean getting a different keyboard.
For one-handed data entry, position the keyboard in front of the keying area.
Use the wrist only for resting
Mouse
Keep your arms close to your side, elbows bent at 90 degrees
Place and use your mouse next to your keyboard
Keep your wrist straight and use your arm to move it around
Monitor
The height of your monitor should be roughly 4-5 inches below eye level
Your eyes should be about 18-24 inches from the screen
Tilt the screen to minimize reflected glare
Alternate the position of document holder on either side of the monitor to change your head position
Vision
Get your vision tested regularly
Take rest breaks for your eyes
Make sure surfaces are clean and dust-free
Adjust the brightness and contrast on your monitors so that characters are brighter than the background
General Work Area
Arrange items (pens, staplers, hole punches, etc.) so that you don’t have to twist or extend frequently
Do not type while holding the phone cradled on your shoulder
Keep the floor space around your desk clear
Reduce excessive noise
Rest Breaks
Take frequent rest breaks and move around, even if just for 30 seconds every hour or so, to ease muscle aches and eye strain
Don’t wait for the pain to seek medical attention
Work Station Quick Check:
Monitor height is slightly lower than eye level and 18”-36” from eyes
Monitor and document stand are at the same distance from eyes
Keyboard and mouse are beside one another and at the same height
Wrists are straight
Shoulders are relaxed and back
Your backrest is adjusted to provide lumbar support
Knees are bent at 60-90 degrees
Feet are supported either on the floor or on a footrest
You have taken a micro break in the last 30 minutes 10. You have altered your body position within the last hour
Exercises:
For tension in the neck and shoulders People who sit at a desk all day are prone to tension in the neck and shoulders. Try this stretch once or twice a day to keep your shoulders relaxed, retracted and upright.
1. Sit comfortably on the edge of your seat with your feet flat on the floor and your back straight 2. Drop your left hand to your side with your fingertips pointing away from your body and lifted so your hand is parallel to the floor. Leave your right hand in your lap. 3. Slowly let your left ear fall towards your left shoulder 4. Raise your left hand out to the side and away from your body until you feel a slight pulling sensation in the side of your neck. If necessary, you can place your hand on the top of your hand and apply gentle pressure to increase the stretch but do not overstretch. 5. Hold for 30 seconds and release 6. Repeat on the opposite side.
For tension in the back
1. Sit in your chair and place your right arm behind your right hip. 2. Twist towards the right side and hold for 10 seconds. 3. Repeat on the left-hand side. 4. Repeat a total of 3 times on each side for every hour of sitting.
Take frequent walk breaks Take walk breaks when you feel sleepy or stressed. A quick walk will increase your energy and focus.
