 What is it:  Creating an environment that is suitable for the individual Goal of Ergonomics: Design the workplace to make it more comfortable for workers and to improve both health and productivity for them. Introduction to the Science of Ergonomics

 GoodBad Example of Good/Bad Ergonomics Atta boy!This kid is gonna fail the course sitting like this.

 Physical Ergonomics Click on one of the buttons to proceed. Rules apply for both desktop computer and laptop.

  Select a chair that is adjustable  Adjustability should include: height, lumbar support and arm rest height  The seat back should in a reclined and relaxed position Chair

  Keep your neck in an upright position with you ear aligned with your shoulder  Avoid having your head forward which could lead to neck strain  Relax your shoulder blades Cervical Spine

  Keep your monitor height at eye level  Having a good height will help maintain an upright spinal posture, which will prevent the neck from dropping into a flexed position Monitor Height

  Position the monitor at an arms length distance away from yourself to help to prevent eye strain  If the monitor is too far away, you will most likely push your neck forward to be able to see the screen Monitor Distance

  You should be able to have both feet flat footed on the ground  If not, lower the chair height or buy a footrest which will position the knee and hip joints in a open posture  Avoid sitting on a bent leg or resting your feet on the legs of your chair  Theses positions can interfere circulation in the lower extremities Foot Position

  Attach a holder to the side of the monitor to prevent repetitive and twisting neck motions Document Holder

  Wrists should be in a neutral alignment  Avoid having the flexed down or extended back position  Do not lean on wrist rests as this could result in carpal tunnel syndrome and change the mechanics of typing Wrists

  Avoid having your elbows and forearms on the chair’s armrests while typing as this pressure is not healthy for the nerves and blood supply  Similar to wrist rests, using armrests can change the techniques of typing  Elbows should be relaxed at your side and typing should appear from the shoulder region Elbows

  Place the monitor and keyboard it in front of you  Keeping the two objects in front of you can prevent rotational strain in the cervical spine Monitor and Keyboard Position

  An adjustable keyboard tray is crucial to providing the ideal joint positions for the upper extremity  Unhealthy positions can lead to nerve compression issues or tendonitis  Remember to type with the least amount of force possible to conserve muscle power and to minimize pressure on the fingertips Keyboard

  Position the mouse at the same level as the keyboard on the adjustable tray  Having a sustained forward posture can lead to shoulder/elbow problems  Best choice: A comfortable wireless mouse allows more freedom than wired models Mouse

  Take frequent breaks when using a computer  Allow your muscles and nerves to recover from your recent activities and recharge for you next session Miscellaneous

 In many technological positions, workers are require to perform repetitive procedures in unhealthy positions. The number of worker injuries and illnesses caused by ergonomic conditions is rising which is costing companies to lose valuable employees. This is also affecting worker’s expenses and lost of work time. Companies need to act on this problem has it is something that won’t go away any time soon. Why is it Important?

 Factors:  Excessive motion  Mechanical stresses  Poor posture  Awkward positioning  Lifting  Vibration  Skin damage Health Problems

  Reduce Glare From Monitor  Adjust the viewing distance and document height  Change seating position  Clean up your workspace  Modify the position of where an object is Possible Solutions
