The present invention concerns a method to mitigate the consequences of an unconfined or partially confined vapor cloud explosion due to the accidental release of a flammable gas in an open area, wherein: In a specific embodiment the release of the flame acceleration suppression product is made by a signal generated by a detector of said flammable gas release or by an operator and before ignition or beginning of an explosion.

Method to mitigate the consequences of an unconfined or partially confined vapor cloud explosion

A method to mitigate the consequences of a vapor cloud explosion due to an accidental release of a flammable gas in an open area, comprising: defining an hazardous area wherein an accidental release of flammable gas is likely to happen; receiving a signal from a detector device able to detect the presence of the flammable gas within the hazardous area, upon reception of a signal indicating the presence of the flammable gas within the hazardous area, generating a control signal to activate a release of a flame acceleration suppression product in the hazardous area, at a rate that is determined as a function of the volume of said hazardous area.
