3. Applications of Stairway and Elevator Pressurization Systems: Is It Really That Easy?



Peter W McDonnell, P.E., Member, McClure Engineering, St Louis, MO 
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?
