Can outside air ever be completely shut off from a space?

What will be an ideal response?


Fire dampers close off the supply of outside air completely so that the fire is not fed any additional oxygen. There are also exclusive systems for special applications that totally shut off the supply of outside air in the event of chemical or biological attack. These dampers should not interfere with normal operation.
