Anthropometrics, Visual Acuity and Fatigue Management in Workplace Design
CSP written lesson, 9 min read. CSP Domain 6: Occupational Health and Applied Science
Written with AI help from the rules it covers, then fact-checked against them. Study aid, not site-specific safety advice. The official rule controls.
What you'll learn
- Calculate a body dimension at a given percentile from a mean and standard deviation
- Choose the correct end of the range for clearance and for reach and add clothing and equipment
- Explain why a design cannot be built for a single-percentile person
- Convert a Snellen acuity to a minimum letter height at a viewing distance
- List employer measures for managing fatigue from long or irregular shifts
What this lesson covers
This lesson covers how to size workplaces and displays for real people: percentiles and the normal distribution, clearance versus reach, why there is no 'average person', how visual acuity is measured and how it sets minimum text size, and how fatigue management fits into design and scheduling.
