Chapter 5 Flashcards
What is ergonomics in OSH
Ergonomics is the study of designing workplace conditions and job demands to fit the capabilities of workers, reducing injury risks and improving efficiency
Why is ergonomics important in workplace safety?
Proper ergonomic design prevents musculoskeletal disorders (MSDs), improves productivity, and enhances overall worker well-being.
What are the main risk factors in ergonomics?
Repetitive movements, awkward postures, excessive force, prolonged sitting/standing, and poorly designed workstations.
What are Musculoskeletal Disorders (MSDs)?
MSDs are injuries or disorders affecting muscles, nerves, tendons, joints, and cartilage, commonly caused by poor ergonomics.
What are examples of MSDs?
Carpal tunnel syndrome, tendonitis, lower back pain, and repetitive strain injuries (RSIs).
How can MSDs be prevented in the workplace?
Implementing proper posture, ergonomic equipment, job rotation, and stretching exercises.
“What is the role of ergonomic assessments?
They identify workplace hazards, evaluate risks, and suggest modifications to improve worker comfort and safety.
How does workstation design impact ergonomics
A well-designed workstation reduces strain by ensuring proper screen height, chair support, and keyboard/mouse positioning
Why is lifting technique important in ergonomics?
Proper lifting techniques reduce strain on the spine and prevent injuries like herniated discs and muscle tears.
What are the key principles of safe lifting?
Keep the back straight, lift with the legs, hold the load close to the body, and avoid twisting movements.
How do prolonged sitting and standing affect workers?
Prolonged sitting can lead to back pain and poor circulation, while prolonged standing can cause leg fatigue and varicose veins
What are solutions for prolonged sitting or standing?
Using adjustable workstations, taking breaks, and alternating between sitting and standing throughout the day
What is the impact of vibration in ergonomics?
Long-term exposure to vibration (from tools or vehicles) can lead to hand-arm vibration syndrome (HAVS) and back disorders.
How can vibration hazards be minimized?
Using anti-vibration gloves, proper tool maintenance, and limiting exposure duration
How does lighting affect ergonomics?
Poor lighting causes eye strain, headaches, and reduced work efficiency. Proper lighting reduces glare and improves visibility
What is the role of training in ergonomic safety?
Training educates workers on proper posture, equipment use, and injury prevention strategies to maintain workplace health
