CIEE CIEE Anthropometry & Human Factors 2

Question 1

Which body landmark is most commonly used as a reference height for setting work surface height at standing workstations?

Accepted Answer

Elbow height

Answer

Elbow height is the standard reference point for setting standing work surface height, with light precision tasks slightly above and heavy tasks slightly below elbow height.

Question 2

What is 'clearance anthropometry' and why is it critical in industrial settings?

Accepted Answer

The measurement of maximum body dimensions to ensure workers fit through passageways, under equipment, and within confined spaces

Answer

Clearance anthropometry uses maximum body breadth, depth, and height dimensions to ensure sufficient space for workers to move safely through, under, or around industrial equipment and structures.

Question 3

How does the use of personal protective equipment (PPE) affect anthropometric design considerations?

Accepted Answer

PPE adds bulk and weight that increases effective body dimensions and reduces dexterity, requiring expanded clearances and control sizes

Answer

PPE such as gloves, respirators, and hard hats increases effective body dimensions and can impair grip and dexterity, requiring ergonomists to account for these additions in workstation design.

Question 4

Which principle describes designing for the extremes of the user population rather than the average?

Accepted Answer

Percentile accommodation design

Answer

Percentile accommodation design explicitly targets defined population extremes (e.g., 5th and 95th percentiles) rather than the average (50th percentile), which would exclude a large portion of workers.

Question 5

What is 'biomechanical modeling' used for in the CIEE evaluation process?

Accepted Answer

Estimating muscle forces, joint moments, and spinal loads during specific work tasks

Answer

Biomechanical modeling quantifies internal forces on muscles, joints, and the spine during specific postures and tasks, helping ergonomists identify which tasks exceed safe load thresholds.
