12.1.2.2-1 Air Exchange

The ventilation system should be capable of introducing fresh air into the control room at a rate of at least

9.4 l/s (20 cubic feet (ft3)/min) per occupant.

Additional Information: In general, the rate of air exchange for enclosed spaces should be at least six complete air changes per hour. For crowded spaces with an enclosure volume of 4.25 cubic meters (m³)(150 ft³) or less per person, a minimum of 0.85 m³ (30 ft³) of ventilation air per minute per person should be introduced into the enclosure, with approximately two-thirds of that volume consisting of outdoor air. For larger enclosures, the air supply rates per person, as well as the proportion of outdoor air, should be in accordance with Figure 12.4. 0700, 5680, 1472G
