Question 1
What is ergonomics?
Ergonomics is the design of tools and work arrangements to fit people and their tasks, improving comfort, safety and effectiveness.
What to learn
Maintain a healthy work environment through clean air and water, cleanliness and ergonomic computer use. Understand eye strain, musculoskeletal discomfort, stress and other occupational overuse problems, and reduce risks through practical adjustments.
- Ergonomics fits the workplace to the worker and task.
- Good posture, screen position and breaks reduce strain.
- Clean surroundings and safe equipment support health and productivity.
- Early reporting of discomfort allows conditions to be improved.
Practical activity
Adjust a workstation: keep feet supported, shoulders relaxed, screen near eye level and keyboard/mouse within easy reach. Use a short work-break schedule and note any improvement in comfort.
Use your school’s prescribed software version and teacher instructions. Keep personal information out of public practice files.
