Overpressure - Effects of Overpressure

Effects of Overpressure

According to an article in the journal Toxicological Sciences,

"Blast overpressure (BOP), also known as high energy impulse noise, is a damaging outcome of explosive detonations and firing of weapons. Exposure to BOP shock waves alone results in injury predominantly to the hollow organ systems such as auditory, respiratory, and gastrointestinal systems."

An EOD suit worn by bomb disposal experts can protect against the deadly effects of BOP.

    “Oh that my Pow’r to Saving were confin’d:
    Why am I forc’d, like Heav’n, against my mind,
    To make Examples of another Kind?

    Oh curst Effects of necessary Law!
    How ill my Fear they by my Mercy scan,
    Beware the Fury of a Patient Man.”
    —John Dryden (1631–1700)

    “Consider what effects which might conceivably have practical bearings we conceive the object of our conception to have. Then our conception of these effects is the whole of our conception of the object.”
