CEAS CEAS Workplace Assessment & Evaluation 2 — Questions and Answers
Question 1: The NIOSH Lifting Equation uses a load constant of how many pounds as its baseline Recommended Weight Limit?
- 51 lbs (Correct answer)
- 35 lbs
- 75 lbs
- 25 lbs
Correct answer: 51 lbs
The NIOSH Lifting Equation uses a load constant of 51 lbs, which is then reduced by multipliers based on task-specific factors like distance, frequency, and coupling.
Question 2: How many task variables does the NIOSH Lifting Equation use to calculate the Recommended Weight Limit (RWL)?
- Six (Correct answer)
- Three
- Four
- Eight
Correct answer: Six
The NIOSH Lifting Equation applies six multipliers — horizontal, vertical, distance, asymmetry, frequency, and coupling — to calculate the RWL.
Question 3: Which assessment method uses a body part discomfort map to collect subjective pain and discomfort data from workers?
- Body Discomfort Survey (Nordic Questionnaire) (Correct answer)
- RULA
- REBA
- Job Strain Index
Correct answer: Body Discomfort Survey (Nordic Questionnaire)
The Nordic Musculoskeletal Questionnaire uses a body diagram to collect self-reported discomfort data by body region from workers.
Question 4: When assessing chair height, what is the primary indicator that the setting is correct?
- Feet are flat on the floor with thighs approximately parallel to the ground (Correct answer)
- Chair seat pan is at the same level as the desk surface
- Knees are fully extended when seated
- Armrests are at shoulder height
Correct answer: Feet are flat on the floor with thighs approximately parallel to the ground
Proper chair height allows the feet to rest flat on the floor while the thighs are roughly parallel to the ground, supporting neutral hip and knee angles.
Question 5: The Strain Index is an ergonomic assessment tool primarily used to evaluate risk for disorders of which body region?
- Distal upper extremity (hand, wrist, forearm) (Correct answer)
- Lower back
- Neck and shoulders
- Knee and ankle
Correct answer: Distal upper extremity (hand, wrist, forearm)
The Strain Index was developed to quantify risk of distal upper extremity disorders based on factors like exertion, duration, and posture.
Question 6: What is the primary purpose of a task analysis during a CEAS ergonomic assessment?
- Identify and document the physical demands, frequency, and duration of each job task (Correct answer)
- Measure worker satisfaction and morale
- Determine production output targets
- Calculate workers' compensation costs
Correct answer: Identify and document the physical demands, frequency, and duration of each job task
Task analysis systematically breaks down job duties to identify physical demands, awkward postures, and exposure durations that drive ergonomic risk.
