A comprehensive software for Quantitative Risk Assessment Studies With Mapping of Hazard zones on your layout plan/Google maps. More...

In all our Dispersion modeling we have very advanced algorithms to locate user defined concentration reached from the source from the time of release so no receptors or grid required. Our software can also take component/Mixture gases heavier than air like H2S, Chlorine etc..


Comprises of Expert EHS softwares: Toxic Gas, Air Dispersion modeling, Fire modeling, Explosion modeling, Stack dispersion, DOW/MOND-Index, Safety-Audit, ASCLAP, SMOD or Release module based on computational fluid dynamics (CFD), Risk Assessment, EMP Evaluation, Dispersion with PRTOBITs, Dust Dispersion and Settling, Accident Analysis, Fire Analysis, Limits curve, Absolute Fatality/Injury (Dispersions, Explosions and Fire-Balls), OHSMS- Evaluation against OHSAS-18001 (Database), House Keeping Evaluation, Unitcon (Unit conversion) and More..
