Accidental release of hazardous chemicals

  1. Plume, Puff, Spill Dispersions based on Gaussian dispersion calculations and modeling, with tabular and graphic display with 6-User defined Isopleths in XY-Slice at Y-Cross wind distance. Full 3-D “CAT-Scan” output possible with dispersion “Cake slicing in XY (Isopleth)  Graphs. Graphics are in colour. It is a complete CAT-Scan with Probits (PROBIT short for Probability Unit, is the percent Fatality and Injury due to exposure to any hazardous agent.). This Advanced Dispersion provides for Mass and volumes of various concentration zones and concentration zone shells of Plumes, Puffs and Spill pool evaporation dispersions.

  2. Pool fire, Tank on fire, jet fire, fireball, flash fire with PROBITs. Graphics are in colour
  3. UVCE, BLEVE, Under ground explosions, mechanical explosions-cylindrical vessel, spherical vessel, Dust explosion with PROBITs. Graphics are in colou4. 
  4. FAR, FN-Curve, ISO-Risk, Individual Risk computations. 

     Graphics mapping are in colour   

         I.      Graphs can be plotted to scale on Site Maps
both in Graphics and AutoCAD .dwg files.

Help on how to do BLEVE simulations


BLEVE (Boiling Liquid Expanding Vapour Explosion) scenarios
A BLEVE is an explosion caused by a liquid, which is boiling and continuing to produce vapour.If the chemical is flammable, it is likely that the resulting cloud of the substance will ignite after the BLEVE has occurred, forming a fireball and possibly a fuel-air explosion. BLEVEs, which result in very large fireballs, occur when process vessels containing flammable materials with high vapour pressures are exposed to significant external heat. 


If Liquid is flammable flashing liquid or flammable liquid

BLEVE scenarios

Under explosion scenario options

  1. Tank-over heating by external source or Mechanical Explosion leading to BLEVE scenario (CnE)  

  2. Tank-over heating by external source or Mechanical Explosion puff delayed internal ignition leading to Unconfined vapour cloud explosion BLEVE scenario (UCE)"

Under fire scenario options

  1. Tank over heating by external source puff Immediate Edge Ignition leading to Fire Ball leading to BLEVE scenario

 If Liquid is non-flammable

Mechanical Explosion scenario

Under explosion scenario options

  1. Tank-over heating by external source leading to Mechanical Explosion (CnE)
