CEA Standards, Policies & Program Management 3 — Questions and Answers
Question 1: The NIOSH Lifting Equation (1994 revision) was designed to be applied in which specific work scenario?
- Two-handed, symmetrical lifts of objects with good coupling in mild thermal environments (Correct answer)
- One-handed asymmetric lifts above shoulder height
- Push and pull tasks on wheeled carts
- Lifts performed in restricted postures such as kneeling or crouching
Correct answer: Two-handed, symmetrical lifts of objects with good coupling in mild thermal environments
The 1994 NIOSH Lifting Equation was validated for smooth, two-handed symmetric lifts with good coupling under mild thermal and humidity conditions.
Question 2: A Recommended Weight Limit (RWL) of 20 kg and an actual load of 30 kg yields a Lifting Index (LI) of 1.5. This value indicates:
- The task is safe for all workers
- Some workers may be at elevated risk; the task warrants ergonomic redesign (Correct answer)
- The task exceeds the maximum permissible limit and must stop immediately
- The task requires engineering controls within 24 hours per OSHA mandate
Correct answer: Some workers may be at elevated risk; the task warrants ergonomic redesign
An LI above 1.0 indicates that the task may pose an elevated injury risk for some workers and ergonomic improvements should be considered.
Question 3: Under OSHA's Recordkeeping Rule (29 CFR 1904), a work-related musculoskeletal disorder requires entry on the OSHA 300 Log when it results in:
- Any report of discomfort lasting more than one workday
- Days away from work, restricted work, job transfer, medical treatment beyond first aid, or loss of consciousness (Correct answer)
- Medical evaluation only, regardless of treatment outcome
- Self-reported pain rated ≥4 on a numeric pain scale
Correct answer: Days away from work, restricted work, job transfer, medical treatment beyond first aid, or loss of consciousness
OSHA's recordkeeping criteria require logging injuries or illnesses that result in days away, restricted work, job transfer, medical treatment beyond first aid, or loss of consciousness.
Question 4: Which ergonomics program element is considered the most critical 'gateway' for ensuring that hazards get identified and prioritized for control?
- Ergonomics training for all employees
- Worksite analysis / job hazard identification (Correct answer)
- Medical management program
- Ergonomics committee formation
Correct answer: Worksite analysis / job hazard identification
Worksite analysis is the foundational element that identifies and prioritizes ergonomic hazards; without it, training and controls lack direction.
Question 5: In ergonomics program management, the 'hierarchy of controls' places which type of control as most effective for reducing MSD risk?
- Administrative controls such as job rotation
- Personal protective equipment
- Engineering controls that eliminate or redesign the hazard (Correct answer)
- Employee training and awareness programs
Correct answer: Engineering controls that eliminate or redesign the hazard
Engineering controls are ranked highest in the hierarchy because they physically eliminate or reduce the hazard at its source rather than relying on behavior.
Question 6: Which standard provides guidance on the ergonomic design of hand tools, specifically addressing grip design, force requirements, and handle dimensions?
- ANSI/HFES 100
- ISO 9241-410
- ANSI/ASME B11.TR7
- ISO 11228-3 (Correct answer)
Correct answer: ISO 11228-3
ISO 11228-3 addresses ergonomic recommendations for pushing, pulling, and handling of low loads at high frequency, including hand tool use.
Question 7: A key principle in developing an ergonomics program 'scope and objectives' document is that goals should be:
- Broad and aspirational to inspire long-term culture change
- Specific, measurable, achievable, relevant, and time-bound (SMART) (Correct answer)
- Focused exclusively on reducing OSHA recordable rates
- Developed solely by senior management without employee input
Correct answer: Specific, measurable, achievable, relevant, and time-bound (SMART)
SMART goals provide clear accountability and measurability, enabling the program to demonstrate progress and adjust strategies over time.
