Study Notes
Introduction to Ergonomics
- Ergonomics combines the Greek terms "ergon" (work) and "nomos" (rules).
- Aims to design tools and tasks to enhance human efficiency.
- Guiding principle: "Make the work fit the person, not the person fit the work."
History of Ergonomics
- Ergonomics began with early humans using tools, marking the first practices of ergonomic principles.
- The interaction between humans and their environment led to significant developments in ergonomics.
Industrial Revolution
- A transition from agrarian economies to industrialization between 1760 and 1840.
- Key developments included transportation and communication advancements.
- Factory systems introduced division of labor, facilitating mass production.
- The usage of materials like iron and steel increased with new energy sources such as coal and steam engines.
Noteworthy Inventions
- Spinning Jenny allowed multiple yarn spools to be spun simultaneously.
- Eli Whitney introduced interchangeable parts in 1775.
- Innovations included the steam engine, telegraph, telephone, and the incandescent light bulb.
- Major contributions from Nikola Tesla (induction motor) and the Wright brothers (first airplane).
Early Ergonomics Literature
- Bernardino Ramazzini highlighted occupational disorders in his 1717 treatise, influencing early ergonomics.
- Wojciech Jastrzebowski coined the term "ergonomics" in 1857 emphasizing a scientific basis for the field.
Impact of World War II
- Significant interest in human-machine interaction arose to improve efficiency with complex military equipment and machinery.
Distinction: Ergonomics vs. Human Factors
- "Human factors" relates to cognitive design issues, while "ergonomics" focuses on physical design issues.
- Ergonomics considers variations among individuals, their limitations, and their predictable responses to workplace situations.
Importance of Human Factors
- Workplace design must account for individual differences in shape and size.
- Recognizes the physical and mental limitations of humans and the need for predictable cognitive responses.
Musculoskeletal System and Disorders
- The musculoskeletal system includes bones, muscles, tendons, ligaments, and connective tissues.
- Musculoskeletal Disorders (MSD) affect movement and stability, resulting in soft tissue injuries.
- Work-Related Musculoskeletal Disorders (WMSDs), also known as Cumulative Trauma Disorders (CTDs) or Repetitive Strain Injuries (RSIs), develop gradually.
Symptoms and Causes of WMSDs
- Common symptoms include discomfort, pain, swelling, numbness, and tightness.
- Major causes involve heavy lifting, awkward postures, repetitive tasks, vibration, and contact stress.
- Risk factors for developing WMSDs are primarily associated with the frequency and manner of physical tasks.
Guidelines for Lifting
- No definitive maximum weight is established; recommendations exist to guide safe lifting practices.
