Ergonomic Regulations OSHA published a draft ergonomic

standard, but it was not approved. However, the OSHA “General Duty

Clause” requires employers to provide a safe and healthy working environment for employees.

OSRHE Guidelines (4/98)

Page 3: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Ergonomics The study of the relationship

between man and machine. When the body is required to

perform repetitive motion, work in an awkward position, or repeatedly lift heavy objects, injuries may develop.

When employees are comfortable they are more productive.

Page 4: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Risk Factors Repetitive activity Holding a position without movement Use of force or strength Localized pressure Awkward positions (Low temperature) (Vibration)

Page 5: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Repetitive Activity Open letters Stapling Flipping through files Sorting letters Keyboard

Computer vs. typewriter

Page 6: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Holding Position w/o Movement

Reduces blood flow Fatigue

Work demands Gripping mouse too tightly Holding phone to ear

Page 7: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Excessive Use of Force Typist – up to 10,000 impacts

per day People diagnosed with carpal

tunnel use 18% more force to do a task

Page 8: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Excessive Use of Force Stapling Stamping Grasping large folders or books Lifting files/books Pushing/pulling heavy file drawer Chair “scooting”

Page 9: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Localized Pressure Sharp edges Keyboard corners Work surface corners Hard or angular chair arm rests

Page 10: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Awkward Positions Press on nerves, stretch tendons

Shoulder and phone Elbow and phone Poor neck postures, movements Leaning, reaching for tools (10-key,

printer, stapler, etc.)

Page 11: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Awkward Positions, Wrist Bending up, down, side-to-side

Inappropriate keyboard height Inappropriate keyboard angle No support for resting hands Splayed elbows Faulty keyboarding/mouse habits

Page 12: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Neutral Body Posture Places the least amount of

stress on the body Physical stress is evenly

distributed “Zero gravity posture” “Neutral position”

Page 13: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Neutral Body Posture Straight back 90° hip bend 90° knee bend Straight

head/neck Relaxed shoulders 90° elbow bend Straight wrists

Page 14: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Upright sitting posture The torso and neck

are approximately vertical and in-line

The thighs are approximately horizontal

The lower legs are vertical

Page 15: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Declined sitting posture Thighs are inclined The angle between

the thighs and the torso is greater than 90 degrees.

Torso is vertical or slightly reclined and the legs are vertical.

Page 16: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Standing posture The legs, torso,

neck, and head are approximately in-line and vertical.

The user may also elevate one foot on a rest while in this posture.

Carpal Tunnel The channel found in the wrist

surrounded by bones and a non-elastic ligament.

Several blood vessels, nine tendons, and the median nerve all pass through this channel from the forearm into the hand.

Page 19: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Carpal Tunnel Certain movements, especially

repeated movements and bent wrists, can cause an increase in pressure in the carpal tunnel.

Symptoms can include tingling, numbness, pain, swelling, and burning sensation in the hand.

Bad and Ugly Too!

Page 31: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Keyboards/Point Devices

Page 32: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Keyboard and Mouse Position

If you can’t lower the keyboard, you may

consider raising your chair. Center the alphabetical section to your body. Keep the keyboard flat. Rest wrists on rest pad only when not typing. Place the mouse next to the keyboard.

About 2-3” lower than desk height

Page 33: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Keyboard Positioning Place the keyboard directly

in front of you at a distance that allows your elbows to stay close to your body with your forearms approximately parallel with the floor.

A keyboard tray may be useful if you have limited desk space or if your chair has armrests that interfere with adequate positioning.

Page 34: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Wrist Rest Placement

Your hands should move freely and be elevated above the wrist/palm rest while typing.

When resting, the pad should contact the heel or palm of your hand, not your wrist.

Page 35: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Wrist Rest Placement

Some desks and computer equipment have hard, angled leading edges.

This can affect nerves and blood vessels, possibly causing tingling and sore fingers.

Alternative Keyboards

Page 39: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Keyboard Placement

Alternative keyboards help maintain neutral wrist postures, but available research does not provide conclusive evidence that using these keyboards prevents discomfort or injury.

Page 40: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Pointing Devices

Adjusting Computer Pointer Sensitivity and speed should feel

comfortable. The pointer should be able to cover the full

screen while the wrist is maintained in a straight, neutral posture.

Sensitivity should be set so you can control the pointing device with a light touch.

Most devices can be adjusted through the computer control panel.

Avoid tightly gripping the mouse or pointing device.

Page 45: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Monitor Position

Page 46: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Monitor Position Monitor in front of the

keyboard, not to side Top of monitor at eye

level Arm’s length away (24-

30” approx.) Up to 10° backward tilt

or flat Text size may need to

be increased for smaller monitors.

Page 47: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Monitor Position The top of the

monitor should be at or slightly below eye level.

The center of the computer monitor should normally be located 15 to 20 degrees below horizontal eye level

Page 48: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Monitor Position Monitor blocks

are simple and inexpensive.

Telephone books are cheaper.

Page 49: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Monitor Position

Page 50: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Bifocal Wearers Bifocal users typically view the monitor

through the bottom portion of their lenses.

This causes them to tilt the head backward to see a monitor that may otherwise be appropriately placed.

As with a monitor that is too high, this can fatigue muscles that support the head. 

Page 51: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.
Page 52: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Monitor Tilt Monitors that are tilted significantly either

toward or away from the operator may distort objects on the screen, making them difficult to read.

When the monitor is tilted back, overhead lights may create glare on the screen. This can result in eyestrain and sitting in awkward postures to avoid eye glare.

Page 53: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Monitor Solutions Lower the monitor so you can maintain

appropriate neck postures. You may need to tilt the monitor screen

up. Raise chair height until you can view

the monitor without tilting your head back. You may have to raise the keyboard and use a foot rest.

Use a pair of single-vision lenses designed for computer work. 

Page 54: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Other Monitor Considerations Adjust brightness as needed. Keep the screen clean.

Page 55: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Glare

Page 56: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Glare

Glare may cause eye strain or headaches.

Position the monitor between overhead lights and perpendicular to windows

Select a glare screen for the model and size of monitor, but only if needed.

Task lighting on the document should not cause glare on the monitor.

EMF “radiation” is NOT an issue.

Page 57: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Glare screens Block up to 99.9%

of ELF/VLF E-field radiation when properly grounded

$250 Glare only $130

Page 58: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Document Holders

Page 59: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Document Position Position documents

next to monitor and at the same height to reduce: Head and neck

movement Eye refocusing

distance

Page 60: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Document Holder

Allows you to place documents at or about the same height and distance as the monitor screen.

Should be stable when loaded with heavier documents such as a textbook.

Provides a sturdy writing surface, if written entries are necessary.

Page 61: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Work Zones

Page 62: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

The location of frequently-used items should remain within the primary work zone.

Work Zones

Telephone Use

Page 64: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Telephone Use Place the telephone in the

primary or secondary work zone, depending on usage patterns.

Cradling the telephone between your neck and shoulder creates an awkward position. Avoid the shoulder-rest device if at

all possible. Consider a phone headset instead.

Page 65: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Telephone Quick Tips Use a speaker

phone or head set for long conversations.

Keep it close enough to avoid repeated reaching.

Page 66: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Work Behavior Eye relaxation techniques

Place palms over closed eyes and relax Focus on far away objects - “20/20 Rule”

Change tasks and/or position every 20 - 30 minutes. Allows muscles to recuperate from static

positioning Improves blood flow to extremities

Microbreaks (do NOT replace regular breaks)

Page 67: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Work Behavior High repetition tasks or jobs that require

long periods of static posture may require several, short rest breaks.

Users should stand, stretch, and move around to provides rest and this allows the muscles to recover.

Alternate tasks whenever possible, mixing non-computer-related tasks into the workday. This encourages body movement and the use of different muscle groups.

Lift CAREFULLY; never twist and lift

Workstation Assessments

Page 69: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Page 75: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Conclusion All you need is common sense. Always work in neutral positions. Modify the equipment around you,

don’t modify your body posture to fit the equipment.

Give adjustments a couple of days. Minimize awkward postures, static

positioning, and repetitive movements.

Laptop Ergonomic Guidelines

Centers for Disease Control and Prevention

Page 80: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Laptop Guidelines The CDC recommends that laptop

computers not be used as a primary computer at home or at work.

Occasional users should: Find a comfortable chair Use a neutral wrist position Position screen to minimize neck

bending

Page 81: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Laptop Guidelines Consider using an external keyboard or

docking station. Take mini-breaks ever 20-30 minutes. Keep viewing distance @18-30 inches. Position keyboard at elbow height. If seated in a side-chair or couch, use a

pillow to support your arms while keying. Clean the screen regularly.

Docking Stations

Page 83: Office Ergonomics/Safety Pamela A. Boatright System Safety, Health & Environment Resource Center Oklahoma State Regents for Higher Education.

Transporting the Computer If computer and accessories > 10

lbs, consider a bag with wheels. Eliminate all unnecessary items

from your briefcase. Carry a laptop in a case with

padded shoulder pad and handle. Shift hands and shoulders to

balance the load.
