About: Explosion Consequence Analysis
Injury/Fatality to Personnel calculations are dependent upon the munitions stored; this ECA is for blast only. Fragments must be calculated using the Gurney Equations for Fragment Velocity.
The national authority should formally accept this risk to the general public if current storage levels are to be maintained
Explosion Consequence Analysis (ECA)
An Explosion Consequence Analysis (ECA) is a structured process, utilizing explosives science and explosives engineering, to provide scientific evidence of the potential hazard or risk to individuals and property from blast effects and fragmentation in the event of an undesirable explosive event.
