This session uses real world designs and installations to illustrate
what aspects of stair pressurization really are as easy as they look and which
aspects contain greater challenges. Topics are addressed that answer questions
such as: Are pressure relief dampers needed? Is a gravity damper good enough?
How many stories can air be supplied to with one injection point? What dampers
are needed on the injection points? What about testing, summer, winter, with or
without smoke?
