Explosion Consequence Analysis

Explosive Risk Management

Explosive Risk Management

An Explosion Consequence Analysis (ECA) is a structured process, utilising explosives science and explosives engineering, to provide objective, scientific evidence of the potential hazard or risk to individuals and property from blast effects and fragmentation in the event of an unplanned explosive event.

The purpose of the ECA is to ensure physical safety, compliance with relevant legislation and to ensure operational continuity for an organisation or company where an explosive threat is identified.

Some examples to scenarios where an ECA may be applicable are as follows:

  • Assessing the vulnerability of exposed sites to ammunition stockpiles.
  • Assessing the vulnerability of exposed sites to Explosive Ordnance Disposal (EOD) activities, such as demolition of unserviceable Explosive Ordnance (EO).
  • Assessing the vulnerability of an exposed site to a possible terrorist attack involving an Improvised Explosive Device (IED).

An Explosion Consequence Analysis (ECA) is typically calculated with a range of atmospheric conditions in order to identify both the best-case and worst-case scenarios.

Underwater Explosive Consequence Analysis

In an underwater environment, an Explosion Consequence Analysis (ECA) might be utilised to quantify the explosive risk  from wrecks containing explosive ordnance or dumped munitions. An ECA for an underwater threat is more challenging that than a threat on the land.

As well as atmospheric conditions conditions, an ECA for a underwater threat may also require tidal variations (depth of water) to taken into account in order to calculate both the best-case and worst-case scenarios.

The TRL Approach

The approach a logical, 4-phased approach to explosive risk management where an ECA is required:

  • Desktop Study. Collect, collate and analyse all available information on the explosive threat.
  • Explosion Consequence Analysis. Identify potential risks to people and property associated with the explosives threat through consequence modelling.
  • Risk Estimation. Identify, through technical analysis, the likelihood of an unplanned explosion.
  • Make Recommendations. Make recommendations for explosive risk mitigation based based upon the outcome of the ECA and risk estimation.
