CPD Hours

Many zone fire models were developed towards the end of the 20th century.
Today, zone models are not used much, but two of these freely available models are still supported (CFAST and BRANZFIRE). Today, the focus is on computational fluid dynamics (CFD), but zone fire modeling can still be useful. CFAST can be used to calculate
               (1) visibility
               (2) concentrations of combustion gases, and
               (3) sprinkler activation time.
CFAST can be used to help evaluate the feasibility of atrium smoke filling.
Dr. Klote is known throughout the world as an expert in smoke control due to his many books, technical papers, articles, presentations, as well as, his 19 years of fire research at the U.S. National Institute of Standards and Technology (NIST). For 11 years after leaving NIST, Klote operated his own consulting company specializing in smoke control. Klote earned his doctorate in mechanical engineering at George Washington University. Dr. Klote is a fellow of SFPE, a fellow of ASHRAE, and a member of NFPA. He is a registered professional engineer in Washington, DC.
