Study Notes
What is Ergonomics?
- Ergonomics is the scientific study of people and their work, derived from Greek words "ergon" meaning work and "nomos" meaning natural rules or laws.
- Ergonomics is the science of fitting workplace conditions and job demands to the capabilities of employees.
Benefits of Ergonomics
- Increased productivity and organisational effectiveness
- Improved management of risk
- Improved wellbeing of staff
- More effective personnel selection
- Reduced product development time
- Increased product sales
- Tasks completed more efficiently and effectively
- Equipment and tools are easier to learn and use
- Improved procedures and training programmes
- Fewer errors occur
- Improved communication within/across teams
Ergonomic Injuries
- Musculoskeletal Disorders (MSDs) or Repetitive Stress Injuries (RSIs) affect ligament, tendon, nerves, muscle, and joints.
- Ergonomic injuries are caused by exposure to ergonomic risk factors such as:
- Repetitive strain
- Prolonged exposure to abnormal temperatures or vibration
- Prolonged awkward posture
- Forceful exertion or using vibrating tools
- Performing repetitive motions
- Using the hand or knee to make repeated impacts
- Heavy, frequent, or awkward lifting
- Standing too long in one position
- Mechanical pressure (leaning against a hard edge)
- Environmental conditions: poor lighting, extreme heat or cold
- Symptoms of MSDs include:
- Painful joints
- Pain in wrists, shoulders, forearms, knees
- Pain, tingling, or numbness in hands or feet
- Fingers or toes turning white
- Shooting or stabbing pains in arms or legs
- Back or neck pain
- Swelling or inflammation
- Stiffness
- Burning sensation
Examples of Ergonomic Injuries
- Wrist/Carpal Tunnel: Wrist injuries including Carpal Tunnel Syndrome
- Elbow: Tennis Elbow
- Shoulder: Shoulder and rotator cuff injuries
- Neck: Neck pain
- Knee & ankle: Sprains, strains, and tears
- Back pain: Lower back pain and injuries
Prevention of Musculoskeletal Disorders
- Improved Work Techniques: use helpful equipment to decrease risk factors
- Personal Protective Equipment (PPE): wear protective gear to reduce injury risk
- Better tools and resources: ensure hand tools fit the job and reduce risk factors
