Most commonly used barricade design methods are based on taking an explosion scenario and treating it as a “TNT equivalent.” A widely used approach in the chemical industry is documented in TM5‐1300. Although this may be a reasonable approach for explosives in cubical barricades, it may not always relate well to the reality of many chemical facilities. This paper discusses some of the limitations of the TM5‐1300 method, the need for a good definition of the hazardous event(s), and the use of computational fluid dynamics to define blast loads for barricade design. © 2005 American Institute of Chemical Engineers Process Saf Prog, 2005
