Office Ergonomics


A safe place to work is not an accident

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.


Ergonomics

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


Cumulative trauma disorders

CUMULATIVE TRAUMA DISORDERS

A type of injury which relates to some aspect of continuous and/or repetitive work and other such activities.

NON-OCCUPATIONAL RISK FACTORS


Office ergonomics

Human Factors

  • People Are Different

  • People Have Limitations

  • People Have Predictable Reactions


Office ergonomics

Risk Factors

  • As these factors increase

  • Force

  • Frequency

  • Awkward Position

  • Temperature

  • Vibration

Injuries increase

Productivity decreases


Early warning signs of ergonomic problems

Early Warning Signs of Ergonomic Problems

Swelling

Discomfort, Pain

Numbness, Tingling

Burning Sensations

Stiffness, loss of range of motion

Weakness

Insomnia


Vital elements the chair

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


The monitor

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.


Office ergonomics

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.


Design and use

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


Office ergonomics

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.


Office ergonomics

Document Position

  • Keep document close

  • Minimize head, neck, or back movement

  • Document holder beneath monitor


Light contrast

Light Contrast

  • Well-distributed diffuse light

  • Use colors to better reflect light

  • Reduce dark shadows


Glare

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


Breaks and stretches

Breaks and Stretches

  • Take frequent breaks

  • “Get up for safety”

  • Take walks

  • Stretch

  • Fitness


Think ergonomics fit the workstation to you

Think Ergonomics Fit the workstation to you


Some guidelines to ensure success

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


Conclusion

Conclusion

  • Provide adjustable workstation

  • Minimize repetitive motion/awkward posture

  • Keyboard and mouse positioning

  • Work process

  • Reduce glare

  • Breaks/stretches
