  1. Department of Administrative Services Office Ergonomics

  2. A Safe Place to work is not an Accident. Attention must be paid to: • Posture • Chair • Keyboard • Mouse • Computer Screens • Lighting • Leg Room • Desk Arrangement • Daily Routine • Total Safety Culture • It is a place where all employees and managers believe that accidents/injuries are: • Predictable • Preventable • Unacceptable • because they affect the health & well • being of the employees.

  3. The study of the worker and the work environment. A way of thinking about the design of tools and equipment the layout of the work environment the work process Ergonomics

  4. CUMULATIVE TRAUMA DISORDERS A type of injury which relates to some aspect of continuous and/or repetitive work and other such activities. force posture frequency

  7. Human Factors • People Are Different • People Have Limitations • People Have Predictable Reactions

  8. Risk Factors • As these factors increase • Force • Frequency • Awkward Position • Temperature • Vibration Injuries increase Productivity decreases

  9. Early Warning Signs of Ergonomic Problems Swelling Discomfort, Pain Numbness, Tingling Burning Sensations Stiffness, loss of range of motion Weakness Insomnia

  10. VITAL ELEMENTS:The CHAIR • Adjust the armrest to allow the shoulders to • remain in neutral position • The backrest should be adjustable to provide • comfortably support. It should not rock • The seat cushion should be in good • condition • Back of knee slightly higher then seat chair • for good blood circulation flow • There should be 5 legs for stability • A waterfall front is recommended • Height adjustment is extremely important • Entire foot sole should rest on floor

  11. Height:Top of screen at eye level Angulation:Minimal tilting Position:Directly in front Distance:18 - 24" away (about an arms length away) Brightness/Image:Adjustable/clear & sharp Color/screen:Multi-color/kept clean THE MONITOR Note: The height and distance of the document which is being copied should be the same as that of the monitor and share the visual space.

  12. The Keyboard POSITION - The keyboard should be positioned directly in front of the operator. Moving it to either side causes fatigue. HEIGHT - Ideally, allows the operator's upper and lower arms to be at a 90 degree angle. 15 degrees either way can cause pain and decrease productivity. ANGULATION - The keyboard should be angled at a downward slope or evenly balanced. It can be elevated in the rear 2 1/2 ", if it does not place the wrists in a compromised position.

  13. Design and Use • Reduce bending wrists by moving entire arm • Wrists should be extended straight, not up and down • Keyboard feet can be used to maintain neutral position

  14. DESK/WORK SURFACE The work surface is correctly adjusted to the physical characteristics of the individual when: 1. Arms can be positioned at 90 degrees 2. Tools are arranged to minimize the distance you have to reach for them 3. There is sufficient room for equipment 4. There is sufficient leg room beneath the desk – find place a place for all the extra stuff somewhere other than under the desk Note: Where the individual's feet can not be positioned flat on the floor, a footrest should be made available.

  15. Document Position • Keep document close • Minimize head, neck, or back movement • Document holder beneath monitor

  16. Light Contrast • Well-distributed diffuse light • Use colors to better reflect light • Reduce dark shadows

  17. Glare • Orient work stations • Glare does not reflect on the screen • Blinds or drapes • Clean the monitor frequently • Glare filters • Use barriers to reduce glare • Tilt monitor slightly lowered • Dark colors and light background

  18. Breaks and Stretches • Take frequent breaks • “Get up for safety” • Take walks • Stretch • Fitness

  19. Think Ergonomics Fit the workstation to you

  20. SOME GUIDELINES TO ENSURE SUCCESS • EMPLOYEE AWARENESS IS ESSENTIAL • IDENTIFY REPETITIVE TASKS/EXPOSURES • RECOGNIZE THAT INITIAL CHANGES MADE • WILL PRODUCE SOME DISCOMFORT • ADJUSTABILITY CAN ACCOMMODATE 90% • OF THE GENERAL POPULATION • CONSIDER SOLUTIONS FOR LAPTOPS • WRIST RESTS AND BRACES ARE NOT • CURE-ALL SOLUTIONS

  21. Conclusion • Provide adjustable workstation • Minimize repetitive motion/awkward posture • Keyboard and mouse positioning • Work process • Reduce glare • Breaks/stretches
