I have been tasked with performing a facilities siting analysis of an existing facility that has a variety of pressure vessels on site. This task involves calculating the overpressure radius of vapor-filled vessels rupturing. Most vessels are 50 psig MAWP and under. I have no direct experience in this and my problem is two-fold:
First, what blast wave pressure is generally considered dangerous? I've found both CDC and FAA recommendations (Calculation of Safety Clear Zones for Experimental Permits) around 1 psi as the minimum standard for possible injuries.
Secondly, what is the industry standard on this analysis? Back when I was interning for an EPC I remember seeing an aerial plant layout with various overlapping circles representing blast radius of concern for various process equipment. This data was used for facilities siting for a new plant construction.
Is there a company that provides this kind of analysis? Or, perhaps, is there a reference for calculations of such blast radii?
