1. Office Ergonomics Awareness Identifying Common Hazards and Taking the Necessary Steps to Keep Yourself Safe

2. The Chair • The chair you choose should be equipped with the adjustable design features that are described in the following images. Office Ergonomics Awareness

3. Backrest Adjustability • The chair should have adequate, adjustable lumbar support. • Adjustable in height • Adjustable in depth • If not: • Try placing a rolled up towel or attach a removable back support cushion to existing back support. Office Ergonomics Awareness

4. Backrest Adjustability • You should be able to recline the backrest either separately from the seat or in synchronicity with the seat at a 3:1 or 5:1 ratio. • The backrest should be able to be locked in at least 3 different positions within it’s adjustment range. Office Ergonomics Awareness

5. Seat Adjustability • The seat pan should be cushioned and comfortable. • It should be adjustable in depth • 2-3 fingers width between front edge of chair and back of your knees. • If not: • Choose a chair with 2-3 fingers width between front edge of chair and back of knees. • Attach a removable back support cushion to existing backrest to shorten seat pan. Office Ergonomics Awareness

6. Seat Adjustability • You should be able to adjust the chair’s seat in height so that you can sit comfortably. • Raise/lower chair to allow feet to rest comfortably flat on floor with hips slightly higher than your knees. • The underside of your thighs should be evenly supported by the surface area of the seat. • If not: • Use footrest if keyboard/desk height requires an elevated chair; or, • Use footrest if the seat cannot adjust down to a comfortable height. Office Ergonomics Awareness

7. Seat Adjustability • The seat should be able to recline either separately from the backrest or in synchronicity with the backrest at a 1:3 or 1:5 ratio. • The seat should be able to be locked in at least 3 different positions within it’s adjustment range. Office Ergonomics Awareness

8. Chair Base • Make sure the casters are appropriate for the floor surface. • Rubber for wooden or concrete surfaces • Hard plastic for carpeted surface • If a carpeted surface and it is difficult to roll the chair’s casters lay down an acrylic mat to reduce friction. Office Ergonomics Awareness

9. Armrest Adjustability • The armrests should be padded and comfortable to rest your elbows and forearms on. • They should be able to adjust in height to below your elbows when you are typing and mousing. • Your armrests should not prevent you from getting close enough to your work surfaces and the keyboard and mouse. • The armrests should be able to adjust in width so that they can be positioned under your elbows and forearms when required. Office Ergonomics Awareness

10. Armrest Adjustability • If armrests are too low/too high: • Remove the armrests. • Add padding to bring them up to a comfortable level. • Only use the armrest during short pauses from typing. • Replace with armrests that can be adjusted to the correct height. • If armrests are too wide: • Adjust to bring them closer together. • Replace seat pan on chair with a narrower one. • Replace with width-adjustable armrests. Office Ergonomics Awareness

11. Chair Adjustability • You should learn how to adjust your chair for optimal fit and comfort. • Ask the vendor to review the chair’s adjustability features with you. • Look for an instruction booklet or look to the manufacturer’s website for assistance. Office Ergonomics Awareness

12. Adjusting Your Chair • If you have an adjustable chair and a workstation that allows you to sit comfortably don’t limit yourself to just one posture. Learn how to adjust your chair! • Our muscles can last longer when we give them many healthy postures to work in. • Move by adjusting your chair, your body and your equipment and tools! Office Ergonomics Awareness

13. Adjusting Your Chair • Its’ recommended that you work in a reclined position for 10-15 minutes of every hour. • If your heels come off the floor when you recline then find something to rest your feet on, like a footrest, that will keep your heels grounded. • You will also need to adjust your keyboard and mouse platform lower while sliding closer to it to prevent reaching • If your keyboard and mouse are on the work surface then you may need to raise your chair a bit and put your feet on a support. • When sitting upright you may need to raise or lower your chair while adjusting the height of your keyboard and mouse and your distance from them. • If you have to take a phone call stand up! Office Ergonomics Awareness

14. Keyboard • The letter ‘H” on your keyboard should be aligned with the centre of the monitor. • If it is not, • Reposition the keyboard and/or monitor to achieve this positioning. Office Ergonomics Awareness

15. Keyboard • Is the keyboard positioned so that your wrists are straight (not bent up / down) while using the keyboard? • If not, • Adjust seat height so that keyboard and mouse are at elbow height. • Raise or lower adjustable work surfaces in systems furniture so that they are just below seated elbow height. • Place keyboard and mouse on articulating keyboard tray and adjust tray height and tilt until wrists are straight. • Retract keyboard feet. • Support arms on armrest when keying or mousing. • Use an appropriately sized keyboard (e.g. external keyboard if laptop is used regularly on desk). Office Ergonomics Awareness

16. Mouse / Pointing Device • Is the mouse located close to you (so your elbow is close to your body and the hand is as close as possible to the mid-line of your body)? • Place mouse/input device beside keyboard at same height. • Use a mouse bridge (i.e. a hard surface that is placed over number pad on keyboard). • Ensure adequate space on either the desk top or a keyboard tray for input devices. • Purchase a shorter keyboard or a keyboard with number pad on left side. Office Ergonomics Awareness

17. Mouse / Pointing Device • Can you place the mouse on your preferred side? • If not, • Purchase a keyboard and mouse platform that permits this positioning. Office Ergonomics Awareness

22. Keyboard Surface • Is there adequate space for both the keyboard and the mouse on the same surface, at the same height? • If not, • Try increasing mouse speed and enlarging the pointer. • Get a wider keyboard platform or a shorter keyboard. Office Ergonomics Awareness

23. Keyboard Surface • Is the keyboard surface adjustable? • If not, • Ensure seat height can be adjusted so that keyboard and mouse sit just below elbow height and use a footrest if you are no longer seated comfortably. Office Ergonomics Awareness

24. Keyboard Surface • If Yes, how is it adjustable: • Height? • If not, ensure seat height can be adjusted so that keyboard and mouse sit just below elbow height and use a footrest if you are no longer seated comfortably. • sliding in and out? • If not, If platform cannot slide all the way under the work surface have the sliding track reinstalled further back or purchase a shorter adjustable arm. • angle (flat, ± tilt)? • If not, Use the feet on the back of the keyboard to make the keyboarding surface flat. Office Ergonomics Awareness

25. Keyboard Surface • Does the keyboard surface have a well-designed palm rest? • If not, • If you do not drop your wrists when typing then no corrective actions are required. • If you drop your wrists to the work surface or work surface edge roll up a towel and place it in front of keyboard. Office Ergonomics Awareness

26. Using a Laptop • Are you using a laptop for more than 2 hours/day cumulatively? • If you are, you are more susceptible to discomfort symptoms in your neck, back, forearms and wrists if you don’t take the necessary steps to separate the keyboard, mouse and monitor from eachother. Office Ergonomics Awareness

27. Using a Laptop • You should get an external keyboard and mouse and position them comfortably according to the previous information. • This could include raising the laptop to eye height using boxes; • Placing the keyboard and mouse on the work surface, raising you chair up and placing your feet on a footrest.
