Health Issues
Essential Implication for Productivity, Efficiency, Safety, and Health in Work Setting

Designing equipment and work arrangements to improve working posture and ease the load on the body.

Information design, to make interpretation and use of handbook, signs, and display easier and less error prone.

Designing equipment and system including computer, so that they are easier to use and less likely to lead to errors I operation.
Objectives of Ergonomics
To ensure that humans and technology work in complete harmony, with the equipment and task aligned to human characteristics.

To have “no pain” computing.
Origins of Ergonomics
A relatively new branch of science, celebrated its50th anniversary in 1999.

Relies on research carried out in many other older, established scientific areas, such as physiology, psychology and engineering.

Originated in World War II, when scientists designed advanced new and potentially improved systems without fully considering the people who would be using them.

It gradually became clear that systems and products would have to be designed to take account of many human and environmental factors if they are to be used safely and effectively.

This awareness of people's requirements resulted in the discipline of ergonomics.
Designing working environments, including lighting and heating, to suit the needs of the users and the task performed.

Design of training arrangements to cover all significant aspects of the job concerned and to take account of human learning requirements.

Design of military and space equipment and systems - an extreme case of demands on the human being.

Designing tasks and jobs so that they are effective and take account of human needs such as rest breaks and sensible shift patterns.
Ergonomics
Study of designing and positioning computer equipment.

An approach which puts human needs and capabilities at the focus of designing technological systems.

A User-Friendly Workstation
Equipment Checklist
Buying Tips
- Ask for equipment that meets American National Standards Institute (ANSI) standards

- Try equipment out before purchasing whenever possible
Computer Terminal
- Easy to use brightness and control knobs
- No perceptible screen flicker
- Detachable keyboard
- Reduced electromagnetic fields (EMF) emissions
- Tilt able screen
- Character size at least 3/16"
TRENDS AND ISSUES

Health Issues
"
Chair
- Back provides firm lower and mind-back support

- Adjustable arm rests, if needed to prevent shoulder fatigue

- Seat and back easily adjustable for height and tilt from seated position without use of tools

- Seat upholstered and padded, curves down at front edge

- 5 casters for stability

Table
- Adjustable easily from seated position without use of tools

- Bi-level to allow independent adjustment of screen and keyboard

- Adequate leg room

- Adequate table top space for required tasks
Accessories
(as needed)
- Foot rest for users whose feet don't rest flat on the floor

- Adjustable keyboard tray, if table is too high

- Wrist rest that is padded, movable, same height as keyboard home row

- Document holder adjustable to screen height

- Glare screen with grounding wire

- Lumbar support cushion, if chair doesn't support lower back

- Telephone headset, task lighting
Health Tips
Reduce Glare to Avoid Eyestrain
- Lower lightning level to about half of normal office lighting

- Avoid placing computer directly under a bank of lights

- Avoid light shinning directly into your eyes or onto your screen

- Use window curtains or blinds if necessary

- Position screen at right angle to window

- Hold a mirror in front of your screen to identify sources of glare

- Use task lightning if necessary
