Question: 1 / 705

How many cubic feet of air does a normal worker performing moderate work typically breathe in an 8-hour workday?

500 cubic feet

1,000 cubic feet

1,500 cubic feet

A normal worker performing moderate work typically breathes in approximately 2,000 to 2,400 cubic feet of air in an 8-hour workday, but when specifically considering common approximations for moderate work, 1,500 cubic feet is a typical estimate. This volume accounts for the worker's respiratory rate, which is influenced by activity level, as moderate work usually leads to an increased breathing rate compared to sedentary activities.

Understanding the volume of air breathed in is essential for evaluating exposure to airborne contaminants and ensuring compliance with occupational health standards. In occupational health contexts, knowing these figures helps in assessing airflow and ventilation requirements in workplaces to maintain a safe environment for workers.
