Ventilation, oxygen uptake, respiratory quotient and carbon dioxide elimination are measured in coal miners and students undergoing the physical activities required in the testing procedure listed in Title 30, Part II of the Code of Federal Regulations in order to provide expected values that would be helpful for the design and testing of self-contained breathing apparatus. Activities include walking, carrying and crawling on a level treadmill; pulley and overcast tasks; and activities on a laddermill and cranking ergometer. Values are given either for the steady state stage of a given activity or a close approximation of it equal to 30 minutes or more.
