Study Notes
Introduction to Ergonomics
- Ergonomics integrates Greek words "ergon" (work) and "nomos" (rules).
- Aims to enhance efficiency by designing tools, equipment, and tasks to fit human capabilities.
- Key principle: "Make the work fit the person, not the person fit the work."
History of Ergonomics
- Originated with the evolution of humans using tools, indicating early ergonomic practices.
- Emphasizes intelligent interactions between humans and their environment.
Industrial Revolution
- Transitioned from agrarian economies to industrial and machine manufacturing from approximately 1760-1840.
- Notable developments included:
- Transportation innovations: automobiles, airplanes, steamships.
- Use of iron and steel, coal, steam engines, and electricity.
- Factory system introduction, promoting division of labor.
Significant Inventions
- Spinning Jenny: revolutionized yarn production, allowing multiple spools to be spun simultaneously.
- Steam Engine by James Watt (1775).
- Interchangeable parts by Eli Whitney.
- Telephone by Alexander Graham Bell (1876) and telegraph by Samuel Morse (1844).
- Incandescent light bulb by Thomas Edison (1879) and diesel engine by Rudolf Diesel.
Pioneers in Ergonomics
- Bernardino Ramazzini (1717): introduced common occupational injuries in "De Morbis Artificum Diatriba."
- Wojciech Jastrzębowski (1857): coined the term "ergonomics", linking it to nature and human interaction.
Cognitive Processes in Ergonomics
- Ergonomics addresses both physical work aspects and cognitive factors.
- Involves understanding how humans think, make decisions, and react in various work environments.
Musculoskeletal System
- The musculoskeletal system supports body form, stability, and movement, composed of bones, muscles, tendons, ligaments, and connective tissues.
Musculoskeletal Disorders (MSDs)
- MSDs affect movement and involve injuries to the musculoskeletal system.
- Common examples include injuries to muscles, tendons, ligaments, and nerves.
Work-Related Musculoskeletal Disorders (WMSDs)
- WMSDs are also known as Cumulative Trauma Disorders (CTDs) or Repetitive Strain Injuries (RSIs).
- They develop gradually due to repeated or excessive physical stress on the body.
Symptoms and Risk Factors for WMSDs
- Symptoms include burning, swelling, discomfort, pain, numbness, and loss of flexibility.
- Common risk factors include:
- Heavy lifting, frequent lifting, and awkward lifting positions.
- Working in poor postures, engaging in vibration, and experiencing contact stress.
Ergonomics in Specific Context
- In the Philippines, the seafood capital is Roxas City, in Capiz.
- Misunderstandings in ergonomics involve improperly fitting the workplace to the worker, neglecting user satisfaction and comfort.
