The HistoryThe History
The need for a ‘good fit’ between humans and their tools was realized early in the development of humanity
16th Century: work injury complaints began to be documented and Scientific Management (a process designed to improve the job process) became popular

The HistoryThe History
WWII prompted further interest in human-machine interaction due to the growing sophistication of military equipment. This included fitting the machine to the size of the soldier

How Ergonomics Relates to How Ergonomics Relates to the Workplacethe Workplace
1. Decreases risk of injury/illness
2. Enhances worker productivity
3. Improves quality of work life
4. Decreases numbers of days absent
5. Enhances worker retention (keeping employees employed with the company)

What are the Hazards?What are the Hazards?The 2 most common physical injuries:
1. Overexertion & Back Injuries
2. Repetitive Strain Injuries (RSI)
![Page 9: Understanding ERGONOMICS](https://reader036.vdocuments.site/reader036/viewer/2022062314/568139f0550346895da1a836/html5/thumbnails/9.jpg)
Overexertion & Lower-Back Overexertion & Lower-Back InjuriesInjuries
Caused by lifting, carrying & lowering heavy material
Material handling is commonly done in organizations and can result in high-risk injuries which are the result of overexertion, poor posture and improper lifting techniques
![Page 10: Understanding ERGONOMICS](https://reader036.vdocuments.site/reader036/viewer/2022062314/568139f0550346895da1a836/html5/thumbnails/10.jpg)
Repetitive Strain Injuries (RSI)Repetitive Strain Injuries (RSI)
• The cause can be traced back to continuous and repetitive actions that produce muscle and/or skeletal strain
• This results in excessive wear and tear on soft body tissue (tendons, nerves & circulatory system)
• Usually RSI affect one or more of the following: fingers, wrists, arms, elbows, shoulders, neck, back and sometimes the lower body
![Page 11: Understanding ERGONOMICS](https://reader036.vdocuments.site/reader036/viewer/2022062314/568139f0550346895da1a836/html5/thumbnails/11.jpg)
Repetitive Strain Injuries (RSI)Repetitive Strain Injuries (RSI)• RSI is becoming the
most common occupational disease
• Examples of RSI include: tennis elbow, golfer’s elbow, telephone operator’s elbow, writer’s cramp and postal worker’s shoulder

Examples of Injuries Examples of Injuries Considered to be RSIConsidered to be RSI
The 2 most common forms of RSIs are:
1. Tendonitis
2. Carpal Tunnel Syndrome

RSI Risk FactorsRSI Risk Factors
1. Spending a large amount of time in
continuous computer use
2. Repetitive actions
3. Poorly designed workstations
4. Poor typing skills (i.e. poor hand position, excessive force in striking the keys, etc)

RSI SymptomsRSI Symptoms
1. Weakness in the limb
2. Tingling/numbness in limb
3. Lack of Endurance (hand tires rapidly)
4. Clumsiness
5. Tightness/general soreness
6. Dull ache, throbbing and/or sharp pain
7. Burning and swelling

ALERT!ALERT!
If you are experiencing RSI related pain,
immediately see your
doctor. The longer you
wait the worse your
condition will get.
