Ergonomics Environment
- 2. Ergonomics! Ergonomics is so much more then just how we sit by the computer The surrounding environment affects the work more then you think
- 3. Ergonomics environment iological subjects are very important man being in the work environment. ubjects above, affects persons in ays. Some in a bad way and can lead to cknesses. s– bad ergonomics • Light • Sound • Vibrations • Air • Temperature
- 4. Affects the environment Industrial work with many particles in the air Computer work Dry eyes Headache Vulture neck Dry office air Air-condition Smoking Fumes
- 5. Dry Eyes Symptoms ● A burning or scratchy sensation in your eyes ● Sensitivity to light ● Eye redness ● A sensation of having something in your eyes ● Watery eyes, which is the body's response to the irritation of dry eyes ● Blurred vision or eye fatigue
- 6. What can be the reason? • The air • long time in front of the screen • Strained eyes
- 7. What to do? • Humidifier • Lower the room temperature – lower the evaporation • Avoid putting your head forward • Eyeglasses
- 8. Glasses ● The employer is only paying for the glasses if your work requires special glasses ● if there is a need of visual aids to help performing the work, the employer should provide this
- 9. Good advices regarding light/eye ergonomics! Let the eyes take a break from the screen every 15 minute and focus on something further away for 1-2 minutes. (eye muscles relax) Good ventilation Screen position at least an arms length from the body Not to hot or cold The top half of the screen should be in eyes height Blink quickly a few times to hydrate the eyes
- 10. Sound
- 11. Everyday exposure • Traffic • Ventilation system • Music • Telephone • Computer work • Birds in the nature
- 12. Health affects • Degraded hearing • Ringing in the ears • Sleep disorder • Degraded learning capacity • higher risk for heart diseases)
- 13. How do we prevent hearing disorders? It is the employers obligation to provide the workers with hearing protectors. This is often used at construction work. It is important to mention that hearing protectors is a temporary solution. The primary aim is to lower the total sound around noisy workplaces.
- 14. How do we prevent hearing disorders? By using different fabrics and materials that can absorb sound.
- 15. Vibrations
- 16. Vibrations Hand and arm vibrations Energy to the body thru handheld tools Total Body Vibrations Energy to the body thru seat or floor Affect the whole body
- 17. How much vibration exposure is needed before the human body is affected? This vary from person to person, how sensitive for vibrations they are. Depending on how long the body has been exposed to vibrations, the damages on the body vary
- 18. The affect on the human body Increased energy consumption Increased muscle activity Increased strain on discs can lead to back pain.
- 19. To prevent some vibration exposure Use back support Some type of damping in the seat Use a material that absorb some of the vibration and does not transfer it to the body Have in mind that you can be exposed to secondary vibration.
- 20. Temperature
- 21. Temperature 34 o C or below – slow metabolism, 45 o C – dead Normal body temperature is around 36,2 o C (35,6 o - 37,8 o C)
- 22. relaxes the work pace exhaustive Lower physical performance Increased numbers of mistakes and accidents Heat affects your work
- 23. How to prevent? Adequate hydration Knowledge, attention Adaption of behavior and physical activity Clothes Activity Condition
- 24. Have always in mind the area of Ergonomics is wide All aspects are important!
