Estimating Blast Pressures and Destruction

A process petrochemical plant producing a synthesis gas high in hydrogen experiences an explosion that results in the destruction of a 1500 cubic foot storage vessel normally held at 50 psig. Unprotected glass window s (i.e., no wire mesh reinforcing, nor tempered) in the plant area 150 feet away from the tank are broken. What pressures were involved  

Applied Process Design for Chemical and Petrochemical Plants 

This overpressure would produce some glass breakage, ceiling damage, and minor structural damage. See Damage Tables 7-24 and 7-25A and B.
