The emergence of performance-based fire safety design has finally made fire safety a partner with the traditionally performance-based disciplines of building security design and chemical/biological/radiological (CBR) building protection.
The code development and adoption process, which defines the construction and design of the vast majority of buildings within the United States, inherently has difficulty reacting to changing conditions. An example is the rapidly emerging threat posed from CBR attack by terrorists. The growing concern over chemical and biological terrorist attacks has exposed the discipline of CBR building protection to a wider base of projects.
