Thanks to all for overwhelming responses to the recent update on Partial Inerting and Operator Earthing.
Looking at recent incidents that have happened in India, this topic was long due to being covered here on my blog. If we look at the Hyderabad Reactor Explosion or Tarapur Explosion or the more recent Moosapet Explosion, all have been suspected to be reactor explosion because of overpressurization.
The companies who are into manufacturing sector usually size their relief devices in the designing stage, when the process to be followed is not finalized and hence they assume a base solvent and size the relief devices for its vaporization in case of an external fire.
Now if we consider the T2 Laboratories accident where MCMT (Methylcyclopentadienyl Manganese Tricarbonyl) was being manufactured, an explosion which was equivalent to 1400 pounds of TNT was a case of a runaway reaction and killed 4 employees of T2 laboratories and injured 32 others. The impact was heard till 15 miles, the debris was found up to one mile away & buildings were damaged till one-quarter of a mile.
