Advanced HAMS-GPS Software Package Vs. Standard HAMS-GPS Software Package

Advantages of advanced HAMS-GPS Software Package

Standard HAMS-GPS Software Package

Advanced Package is a single module taking you from Input Data to Final QRA-Results without any data transfer!

The standard package that has several software requiring Manual data transfer from one module to another.

Advanced Package is extremely user friendly and does not need advanced knowledge of QRA

The Standard Package requires advanced knowledge of HSE and QRA.

The Advanced Package enables in a single stretch of button clicks all simulations from Chemical Storages and Properties through Scenario Development, SMOD, Scenario Simulations for all types of Dispersions, Fires, Explosions leading to Risk Assessment results including FAR, FN-Relation, ISO-Risk and ALARP in one go.

The standard module requires multiple manual data entry and multiple simulations for each module separately, resulting in lot of Manual Unit conversion of Data from one Simulation in to a different Unit for another Module and so on.

The Advanced Package Enables scale plotting of all Graphic outputs on Auto Cad Files using bulit in screen capture, on Graphic Files and also on Blank sheets as per user defined scale and Wind orientation.

The standard package does not have this scale plotting facility. It gives fixed scale graphs in vertical position only, with no reference to wind direction

The Advanced Package under Risk Assessment option includes built in computation of Risk based Investigation (RBI) Matrix.

RBI-matrix is available in Standard package only as a separate module and has to be run after manual data entry by taking the data from other simulations only.

The Advanced Package ALARP diagram has Scale adjustment facility so you can see each scenario distinctly from other closely positioned scenarios, a facility unique for any ALARP Software available.  

Mapping of hazardous zones on picture files is available in advanced software only.

The Standard ALARP Module gives a fixed scale ALARP and closely falling scenarios all get overlapped making difficult to read.

The Advanced Package is specially designed for  EHS-Research and EHS-management.

The Standard Package is specially designed for EHS-Research work


Netherlands QRA Methods  Vs.  HAMSAGARS  HAMS-GPS QRA Method   

1.The ‘Red Book’, describing the methods for determining and processing probabilities, is to be used to derive scenarios leading to a loss of containment event [CPR12E].   

2.The. ‘Yellow Book’ describes the models to determine the outflow and dispersion of dangerous substances in the environment [CPR14, CPR14E], and finally,   

3.The ‘Green Book’ describes the impact on humans of exposure to toxic substances, heat radiation and overpressure [CPR16].

1. Has Provision for determining Scenarios and Probabilities of failures leading to Containment Loss as per Math. Models Prescribed by World Bank Guidelines and EPA Requirements. Also allows for User Defined Failure Probabilities as given in your Guidelines Para 3.A.2 on Failure Data.

2. Has Provisions for Source Modeling including: Gas/Liquid for any density Flow through pipe, through hole, Flashing Liquids, Pool evaporations due to substrate heat transfer (Rapid-1-min.), heat conduction and wind.  

3.PROBIT Modeling: Probability Units for computing percent and Absolute fatality and injury for Dispersions under Stability Classes , Fires (Jet, Flash, Pool) and Explosions (UCVC, CVC, BLEVE, Dust) as per your Guideline Para-4.8. and para-5   

Exclusion of particular substances

Excludes all Non-hazardous (Non-Toxic, Non-Flammable, Non-Explosive) substances and covers only those classified as Hazardous under UN-Classification of Hazardous Substances.

The Selection Method  

Allows only Maximum Credible Loss Scenarios (MCLS or Maximum Credible Accident Scenarios (MCAS) as per Scenarios as per World Bank Technical Paper-55.

Definition of installations in an establishment.  

Definitions of Each Installation Is carried out based on Database of all Hazardous Chemicals and Quantities Stored and Type of Storage in each Installation and MCLS/MCAS Scenarios Developed

Loss of Containment Events (LOC)

Allows for Selection of LOC Events based on all Conditions given in your Guidelines for all Types of Storages and Piping systems. Inclusions of LOCs shall be only for those having equal to or Greater than 10-8  Probability and 1% Lethal Damage occurs outside Facility Boundary and along Transport Route.

Release inside a Building

Procedure given in your Guidelines Para-4.6.3 shall be followed

Fires and plume rise

Our Software takes in to account

Probability of Ignition  

Our Software has Built in computation of Probability of Immediate, Delayed Onsite and Offsite Ignition and also allows user defined values as required and shall use the values given under Para-4.7 and Appendix-4A of your Guidelines.

Substances both toxic and flammable  

Our Software Allows for Without Ignition (Only Toxic Effects) and with Ignition (Fires and explosions) Scenarios as per your Para-4.7.3.

Meteorological data  

Our Software Allows for use of Pasquill-Gifford Models: A, AB, B, BC, C, CD, D, DE, E, EF, F and Uncertain (UC)

Repression Systems  

Our Software provides Recommendations for all requisite Repression Systems required for containing/Minimizing damage effects.

Calculation and Presentation of Results


Our Software provides for Computation of Individual in terms of Fatality Accident Rate (FAR), and societal Risks in Terms of FN-Curve and ISO-Risk in 8-Orientations and Acceptability of Risk as per ALARP Model of HSE-UK and shall be presented in tabular and Graphic forms on Google maps as required under Para-6 of your Guidelines.

Quantitative Environmental Risk  

Our Software provides for Offsite percent and Absolute Injury and Fatality numbers in 8 Orientations as required under Para-7 of your Guidelines.
