A bit about me
Self-employed consultant
First encountered ergonomics when studying
Design & Technology ‘O’ Level
(ask your parents)
‘A’ Levels – Maths, Chemistry & Physicals
Degree – Chemical Engineering
Applying ergonomic principles to safety
Mostly oil, gas & chemical industry.

What is Ergonomics?
Comes from two Greek words
"ergon", meaning work, and
"nomos" meaning "laws“
What does it mean to you?
4
To many people
Ergonomics is about the size of people
5
But ergonomics covers much more
6
Ergonomics is…
The application of scientific information
concerning humans:
Anatomy;
Physiology;
Psychology.
Designing objects and systems to be:
Easy to use (usability);
Used without error (reliability);
Used without causing harm to the person or other
who may be affected (health and safety).

It’s not a new idea

YouTube – Frank Gilbreth – Bricklaying ergonomics

Frank Bunker Gilbreth
1885 – Motion and Fatigue Study of bricklaying
Identified that stooping twice for each brick was
fatiguing and slow
New equipment
Reduced actions per brick from 18 to 5
Increased bricks laid per hour from 125 to 350.

Let’s study this class
Line up in height order
Clearly the shortest and tallest people have
different ‘reach distances’
Lets take the average person from the class
Stand by the white board and draw lines at the
highest and lowest points you can reach without
stretching or bending
Is this a suitable range for the class?
How should we choose heights that suit all (or
most) of the class?
