What is the primary purpose of conducting a task analysis before selecting an ergonomic assessment tool?
Answer: To identify the key physical demands and risk factors present in the job
Task analysis identifies the physical demands, postures, and risk factors of a job, guiding selection of the most appropriate assessment tool.
Which outcome measure from the NIOSH Lifting Equation indicates that the lifting task exceeds recommended limits?
Answer: Lifting Index (LI) > 1.0
A Lifting Index greater than 1.0 indicates the recommended weight limit has been exceeded and the task poses increased injury risk.
In ergonomic assessment, inter-rater reliability refers to:
Answer: The degree of agreement between two or more independent observers
Inter-rater reliability measures how consistently different observers score the same task using the same assessment tool.
Which type of measurement provides the most objective data for assessing whole-body vibration exposure?
Answer: Triaxial accelerometer mounted on the seat or floor
ISO 2631 recommends using triaxial accelerometers to objectively measure whole-body vibration in three orthogonal axes at the worker's seat or feet.
The 'coupling' multiplier in the NIOSH Lifting Equation accounts for:
Answer: The quality of the hand-to-object grip or connection
The coupling multiplier adjusts the Recommended Weight Limit based on how well the worker can grip the load (good, fair, or poor coupling).
When using OWAS (Ovako Working Posture Analysis System), how are posture categories combined to determine action priority?
Answer: Body region scores for back, arms, and legs are combined using a lookup table
OWAS uses a predefined lookup table that cross-references back, arm, and leg codes along with load/force to assign one of four action categories.
A job requires sustained pinch grip for 70% of an 8-hour shift. Which assessment tool is most appropriate to quantify this specific risk?
Answer: Strain Index
The Strain Index evaluates risk factors for distal upper extremity disorders including intensity of effort, duration per exertion, and efforts per minute — ideal for pinch-grip tasks.
