Ergonomics Exam Questions With 100%
Verified Answers
Physical Demands Description -
correct answer ✅Also known as a PDA (Physical Demands
Analysis).
Used to capture physical movements and environmental conditions
associated with the workers' job.
These jobs demands must be collected before assessing hazards
and implementing controls.
Primary ergonomic risk factors for musculoskeletal disorders: -
correct answer ✅Repetition, Force and Posture
Secondary ergonomic risk factors for musculoskeletal disorders: -
correct answer ✅Vibration and Temperature
tool balancer -
correct answer ✅reduces force of a drill
Stenosing Tenosynovitis (Trigger Finger) -
correct answer ✅Trigger finger occurs in individual or multiple
fingers and results when the tendon wickets or sheath swells
The finger then gets stuck in a flexed position; Catches as it runs in
and out of the sheth; Must passive straighten

Verified Answers
Higher prevalence in meatpacking jobs that require static grasping
of power knifes activated by a trigger
Non occupational factors such as diabetes, thyroid disease and
arthritis are usually the cause
Tool improvement should allow for a longer trigger that allows the
use of two or three fingers to activate the drill. This reduces
discomfort and minimizes the risk for injury
Ergonomic Assessment Tools -
correct answer ✅Lifting/lowering tasks: WISHA lifting calculator or
NIOSH lifting equation
Upper body posture: Rapid Upper Limb Assessment (RULA)
Entire body posture: Rapid Entire Body Assessment (REBA)
Pushing/pulling: Snook Tables
Hand-Arm Vibration: HAV Calculator
Screening tools: WISHA Caution Zone Checklist and WISHA Hazard
Zone Checklist
NIOSH Lifting Assessment/equation -
correct answer ✅-Limit a worker could lift during a task for a
SPECIFIED period, without increased risk of injury/LOW BACK pain
-good for lifting weight
