HACCP Workplace Ergonomics & Health 2 — Questions and Answers
Question 1: In a food processing facility, which ergonomic risk factor is most commonly associated with repetitive slicing tasks on a production line?
- Whole-body vibration
- Cumulative trauma from repetitive motion (Correct answer)
- Extreme temperature exposure
- Excessive noise levels
Correct answer: Cumulative trauma from repetitive motion
Repetitive slicing creates cumulative trauma disorders (CTDs) due to repeated micro-stresses on tendons and muscles.
Question 2: A HACCP team is assessing ergonomic hazards at a fish filleting station. Workers stand on concrete floors for 8-hour shifts. What is the PRIMARY ergonomic intervention?
- Install anti-fatigue matting (Correct answer)
- Reduce shift length to 4 hours
- Require workers to wear steel-toe boots
- Add overhead lighting
Correct answer: Install anti-fatigue matting
Anti-fatigue matting reduces compressive forces on joints and decreases lower-back and leg fatigue during prolonged standing.
Question 3: Which OSHA concept requires employers to evaluate and reduce musculoskeletal disorder (MSD) risk factors in food production settings?
- General Duty Clause (Correct answer)
- Hazard Communication Standard
- Process Safety Management
- Lockout/Tagout Standard
Correct answer: General Duty Clause
OSHA's General Duty Clause requires employers to provide a workplace free from recognized hazards, including ergonomic MSD risks.
Question 4: A worker in a poultry plant reports tingling and numbness in the fingers after months of deboning. Which condition is most likely?
- Rotator cuff tear
- Carpal tunnel syndrome (Correct answer)
- Plantar fasciitis
- Trigger finger
Correct answer: Carpal tunnel syndrome
Carpal tunnel syndrome results from compression of the median nerve, commonly caused by repetitive wrist flexion in deboning tasks.
Question 5: When designing ergonomic workstations for HACCP-regulated food packaging lines, work surface height should be adjusted to:
- Shoulder height for all tasks
- Elbow height to minimize shoulder and back strain (Correct answer)
- Hip height to allow bending
- Floor level to maximize reach
Correct answer: Elbow height to minimize shoulder and back strain
Elbow-height surfaces keep arms in a neutral position, reducing shoulder elevation and spinal flexion during packaging tasks.
Question 6: A food plant ergonomics program identifies 'forceful exertion' as a key risk factor. Which task modification best addresses this?
- Increase worker training frequency
- Use power tools or fixtures to reduce grip force (Correct answer)
- Add more frequent quality checks
- Install brighter lighting over workstations
Correct answer: Use power tools or fixtures to reduce grip force
Power tools and holding fixtures reduce the hand force workers must exert, directly lowering forceful exertion risk.
Question 7: In the context of HACCP and worker health, why is employee fatigue considered an indirect food safety hazard?
- Fatigue causes workers to sweat more, contaminating product
- Fatigued workers are more likely to make errors that compromise CCP monitoring (Correct answer)
- Fatigue reduces appetite, affecting product tasting
- Fatigue has no relationship to food safety outcomes
Correct answer: Fatigued workers are more likely to make errors that compromise CCP monitoring
Fatigued workers are more prone to lapses in concentration, increasing the risk of missing critical control point deviations.
