UNIVERSITY OF TECHNOLOGY, JAMAICA OCCUPATIONAL ERGONOMICS Tutorial 1 Tutorial Session: Wednesday: 3pm – 6pm Date: January 20,2020 REVIEW QUESTIONS 1. What are the objectives of ergonomics? Enhance effectiveness and efficiency of work (human activities): convenience, reduced errors, increase productivity. Enhance desirable human values: safety, reduced fatigue/ stress, comfort, acceptance, job satisfaction 2. How do physical, chemical and biological hazards relate to ergonomics? Biological Biological hazards include viruses, bacteria, insects, animals, etc., that can cause adverse health impacts. For example, mould, blood and other bodily fluids, harmful plants, sewage, dust and vermin. Chemical Chemical hazards are hazardous substances that can cause harm. These hazards can result in both health and physical impacts, such as skin irritation, respiratory system irritation, blindness, corrosion and explosions. Physical Physical hazards are environmental factors that can harm an employee without necessarily touching them, including heights, noise, radiation and pressure. 3. What are the consequences of poorly designed jobs? Some other consequences could include: Increased physical and mental exhaustion and stress Low morale within the team Lack of individual and team motivation Low productivity/ unsatisfactory work Increased costs on hiring and training Employee turnover increase 4. What are cost of poor ergonomics in workplace? Cost for the worker: Physiological & physiological •Localized muscle fatigue •Stress •Accidents •Low job satisfaction •Low quality of work life Cost for the company: •Increased risk for accidents and overexertion •Increased turnover & absenteeism •Pressures on wage level •Difficulty finding replacements •Extended time for training & acclimatization •Product/technology rejection Cost of poorly designed jobs Cost for the company: • Low employee morale • Increased breaks • Lower productivity and quality • Difficult return to job (recovery) • Frequent short duration medical absences • Insurance cost • Legislation & Union support REVIEW QUESTIONS 1. What are the main body parts that impact musculoskeletal disorders? Bones Tendons Muscles Ligaments 2. How do physical, chemical and biological hazards relate to ergonomics?

Standing Supine position Standing tall Face and eyes forward Hands at sides Palm forward Heels together Big toes adjacent 4. Define Reference frames When an organism is in its standard anatomical position, positional descriptive terms are used to indicate regions and features. The Reference frames includes: Median or sagittal plane Divides the body into equal right and left halves Coronal plane Divides the body into anterior or posterior parts Horizontal plane Divides the body into superior and inferior parts 5. What are the spatial anatomical relationships? Anterior (ventral): nearer the front surface of the body Posterior (dorsal): nearer the back surface of the body Superior: nearer the crown of the head Inferior: nearer the soles of the feet Pronation: palm from posterior to anterior Suppination: palm from anterior to posterior Medial: Closer to the midline Lateral: Farther from the midline References Harvey, A.
