Study Notes
Introduction to Ergonomics
- Ergonomics derives from the Greek words "ergon" (work) and "nomos" (rules).
- Focuses on designing tools and tasks to enhance human capabilities.
- Principle: "Make the work fit the person, not the person fit the work."
History of Ergonomics
- Human evolution: Early tool use marked the beginnings of ergonomic practices.
- Development progressed through interaction between humans and their environment.
Industrial Revolution
- Transition from agrarian economies to industrial production (1760-1840).
- Innovations included transportation advancements (automobiles, airplanes) and communication (telegraph, radio).
- Factory system introduced division of labor, increasing efficiency and productivity.
Important Inventions
- Spinning Jenny: Multi-spindle frame increased yarn production efficiency.
- Interchangeable Parts: Introduced by Eli Whitney, revolutionizing manufacturing.
- Sewing Machine: Innovated by Elias Howe, enabling mass production of clothing.
- Steam Engine: Developed by James Watt, pivotal for industrial machinery.
- Light Bulb: Invented by Thomas Edison, enhancing working environments.
- Induction Electric Motor: Created by Nikola Tesla, vital for modern electricity usage.
- First Airplane: Developed by Orville & Wilbur Wright, a landmark in transportation.
Contributions to Ergonomics
- Bernardino Ramazzini: Identified work-related injuries in 1717, foundational for occupational health.
- Wojciech Jastrzebowski: Coined the term "ergonomics" in 1857, linking it to natural science insights.
Ergonomics and WWII
- World War II stimulated interest in ergonomics for human-machine interaction, particularly with complex military technology.
Ergonomics vs. Human Factors
- Ergonomics emphasizes physical design; human factors focus on cognitive aspects.
- Differentiation helps tailor designs to accommodate diverse human capabilities and limitations.
Key Human Factors in Workplace Design
- Variety in human shapes and sizes necessitates customized designs.
- Recognition of physical and mental limitations is essential.
- Predictable human reactions and expectations must be considered in task design.
Musculoskeletal Disorders (MSD)
- MSD refers to injuries affecting movement, involving muscles, tendons, ligaments, and other connective tissues.
- Work-related MSD (WMSD) includes conditions like repetitive strain injuries and soft tissue injuries, resulting from cumulative trauma.
Symptoms and Causes of WMSDs
- Symptoms: Discomfort, pain, swelling, numbness, inflammation, and reduced flexibility.
- Causes: Heavy lifting, awkward postures, repetitive motions, vibration, and contact stress.
Risk Factors for WMSDs
- Frequent or awkward lifting increases the risk of developing WMSDs.
- Workplace design should aim to minimize these hazardous activities to improve safety and productivity.
Lifting Recommendations
- Guidelines exist for maximum weight individuals can lift safely, ensuring ergonomic compliance in job design.
