I wrote the math stuff in LaTeX, but started to wonder about the mentioned "Wiebull's formula". I am aware of Weibull's distribution that is written in the same form sans the constant. Are these the same? —Preceding unsigned comment added by 212.50.133.12 ( talk) 19:10, 10 January 2010 (UTC)
The formula appears to be empirically derived and appears to be from: H.R.W. Weibull, "Pressures Recorded in Partially Closed Chambers at Explosion of TNT Charges," Annals of the New York Academy of Sciences, 152, Art. I, pp. 357-361, Oct 1968. Someone should verify this and add it as a reference. Kevin Purcell ( talk) 01:31, 7 April 2010 (UTC)
I feel like it should be more clear that this equation only relates to explosions in closed chambers, and has nothing to do with calculating an explosion in open air. 66.185.79.254 ( talk) 23:19, 3 April 2014 (UTC)
I have deleted the section of overpressure effects because the values presented are misleading. While I do not have first hand knowledge of explosive effects, other references on explosive power indicate that explosive overpressure is approximately 4000 psi for TNT near the explosive. The overpressures referenced in the table are clearly meant to be interpreted as being some distance away from a defined quantity of an explosive. However, these variables are not specified. While the damage levels seem to me to be consistent with published literature, a more reliable source should be found to substantiate these effects, rather than a conspiracy-theory backing account insisting that severe burn injuries cannot be caused by explosives, and that a "mini-nuke" was responsible for the event in question.

I question the levels set out in the table, with 10psi ripping off limbs.
The estimation seems to be based on destruction of buildings, rather than actual effects.
See second table on the page:
http://response.restoration.noaa.gov/oil-and-chemical-spills/chemical-spills/resources/overpressure-levels-concern.html
That being said, this refers to enclosed refuge chambers
http://www.cdc.gov/niosh/docket/archive/pdfs/NIOSH-125/125-ExplosionsandRefugeChambers.pdf, mentioning the 10psi as deadly. — Preceding

I intend to remove the following from the article as it's about a different subject to atmospheric/blast overpressure that the rest of the article is about (see WP:NAD). This could be placed in its own article, but it's completely uncited. DexDor ( talk) 13:45, 16 September 2012 (UTC)
The result of the move request was: not moved. ( non-admin closure) KCVelaga ( talk) 16:45, 13 February 2019 (UTC)
Overpressure → blast overpressure – Overpressurising a pipeline is something else entirely. 86.12.160.194 ( talk) 09:40, 6 February 2019 (UTC)
