HACCP Workplace Ergonomics & Health 3 — Questions and Answers
Question 1: A meat packing facility operates at 34°F (1°C) to maintain food safety. What ergonomic hazard does this cold environment primarily create?
- Increased risk of heat exhaustion
- Reduced hand dexterity and increased injury risk (Correct answer)
- Higher risk of dehydration
- Accelerated microbial growth on surfaces
Correct answer: Reduced hand dexterity and increased injury risk
Cold temperatures reduce blood flow to extremities, impairing hand dexterity and grip strength, which increases the likelihood of musculoskeletal injuries.
Question 2: Which ergonomic assessment tool uses a scoring system to evaluate posture, load, and repetition for upper-limb tasks in food processing?
- FMEA (Failure Mode and Effects Analysis)
- RULA (Rapid Upper Limb Assessment) (Correct answer)
- CAPA (Corrective and Preventive Action)
- SSOP (Sanitation Standard Operating Procedure)
Correct answer: RULA (Rapid Upper Limb Assessment)
RULA provides a quick postural analysis of upper-limb exposure to ergonomic risk in tasks like food trimming or packing.
Question 3: A baked goods facility requires workers to carry 50 lb flour sacks from a storage area to mixers. What is the most effective ergonomic control?
- Provide back braces for all workers
- Install mechanical conveyor or pallet jack system (Correct answer)
- Train workers in proper lifting technique only
- Reduce flour sack weight by 5 lbs
Correct answer: Install mechanical conveyor or pallet jack system
Mechanical handling equipment eliminates the manual lifting hazard entirely, which is more effective than administrative or PPE controls.
Question 4: In HACCP-compliant facilities, job rotation is used as an ergonomic control. What is its primary limitation?
- It is prohibited by OSHA regulations
- It only works if rotated tasks use different muscle groups (Correct answer)
- It increases cross-contamination risk between stations
- It requires FDA approval before implementation
Correct answer: It only works if rotated tasks use different muscle groups
Job rotation only reduces MSD risk if alternate tasks engage different muscle groups; rotating between similarly stressful tasks provides no ergonomic benefit.
Question 5: A HACCP coordinator notices that workers frequently reach overhead to retrieve packaging materials. What injury risk does this overhead reaching primarily create?
- Knee ligament strain
- Shoulder impingement syndrome (Correct answer)
- Lumbar disc herniation
- Achilles tendon rupture
Correct answer: Shoulder impingement syndrome
Sustained or repetitive overhead reaching narrows the subacromial space in the shoulder, leading to impingement of rotator cuff tendons.
Question 6: Which of the following best describes the term 'neutral posture' as used in workplace ergonomics programs in food facilities?
- A posture where the worker is completely still
- Body position where joints are near mid-range and muscles are minimally loaded (Correct answer)
- Standing upright with arms fully extended
- Sitting in a reclined position at 135 degrees
Correct answer: Body position where joints are near mid-range and muscles are minimally loaded
Neutral posture keeps joints at mid-range positions, minimizing stress on tendons, ligaments, and muscles during work tasks.
Question 7: Under HACCP principles, how should a recurring ergonomic injury at a specific CCP monitoring station be documented and addressed?
- Document as a personal medical issue unrelated to HACCP
- Record in the corrective action log and modify the workstation design (Correct answer)
- Reassign all workers away from that station indefinitely
- Report only to the company's insurance carrier
Correct answer: Record in the corrective action log and modify the workstation design
Ergonomic injuries at CCP stations must be logged and trigger corrective action, as they indicate a systemic hazard that may also compromise monitoring reliability.
