The minimum fresh air supply per worker at maximum staffing is what?

The minimum fresh air supply per worker at maximum staffing is what?

• A. 2 cubic meter per minute per man
• B. 1 cubic meter per minute per man
• C. 3 cubic meter per minute per man
• D. 4 cubic meter per minute per man

Answer: (A)

Ventilation planning uses a per-person air requirement so air quality stays safe as the number of workers changes. The standard minimum fresh air supply per worker at maximum staffing is two cubic meters per minute for each person. This rate helps maintain adequate oxygen levels and dilutes heat, dust, and any contaminants when occupancy is at its peak. If you used less than this, air quality could drop with more workers; using more would exceed the baseline standard and waste capacity. So, the correct value is two cubic meters per minute per worker, and you’d multiply by the number of workers to get the total fresh air needed.
