Which observational method involves recording worker postures at fixed time intervals throughout the shift?
Answer: Work sampling
Work sampling involves making instantaneous observations at random or fixed intervals to estimate the proportion of time workers spend in various postures or activities.
The REBA (Rapid Entire Body Assessment) tool assigns a final action level. What does action level 3 indicate?
Answer: Investigate and implement changes immediately
A REBA action level 3 (score 8–10) indicates high risk, requiring investigation and implementation of changes immediately.
When conducting a walkthrough survey, which tool is most appropriate for documenting the physical layout and workstation dimensions?
Answer: Tape measure or laser distance meter
A tape measure or laser distance meter is used during walkthrough surveys to capture workstation dimensions for ergonomic evaluation.
In ergonomics assessment, a 'task analysis' primarily aims to:
Answer: Identify the specific demands and subtasks that make up a job
Task analysis systematically breaks a job into component subtasks to identify demands, sequences, and potential hazard exposures.
Which document is typically used at the START of a formal ergonomics program assessment to triage high-risk jobs?
Answer: Symptom survey or discomfort survey
Symptom or discomfort surveys are administered early to identify departments or tasks where workers report musculoskeletal complaints, guiding prioritization.
The Strain Index (SI) is specifically designed to assess risk of disorders affecting which body region?
Answer: Distal upper extremity (wrist, hand, forearm)
The Strain Index evaluates six task variables to predict risk of distal upper extremity disorders including the wrist, hand, and forearm.
During an ergonomics assessment, 'pinch grip force' is most accurately measured using which instrument?
Answer: Handheld dynamometer configured for pinch
A handheld dynamometer with a pinch attachment directly measures lateral, palmar, or tip pinch grip force in Newtons or pounds.
