RELEASE SCENARIO or BLAST LOAD

The basis for the blast design or analysis is the determination of the blast load.

There are two methods, that may be applied:
1. Use pre-established dynamic load or design scenario (own or industry standards).
2. Determine blast load based on an explosion as a result of a design release scenario.

JKLconsult has the tools!
JKLconsult has developed a generic BLAST DESIGN GUIDELINE based upon the accepted practices of the chemical and petrochemical industries. This guideline contains recommended blast load to be used for detailed design of buildings subject to explosions in chemical plants. The guideline may be adopted by the client with or without revisions and/or additions. For more information about this very important component of your process safety management program, please contact JKLconsult.

For preliminary design JKLconsult may develop crude RELEASE SCENARIO data based upon the type of chemical (hydrocarbon), pressure, temperature, maximum quantity, etc. using computer program, FLASH. The program considers progressively worse scenarios from a small leak (pump seal) to total loss of containment.

The release scenario data combined with information about the physical environment at the stipulated location of the blast is used to determine the blast overpressures and other design data using the Baker-Strehlow and the Multi-Energy Methods.

In the case of terrorist bombing the energy (mass) of the stipulated explosive charge is converted to the equivalent TNT explosion for which the blast load is determined.
