External - A release of energy that causes a pressure discontinuity or blast wave. Internal - The bursting or rupture of an enclosure or container due to the development of internal pressure from a deflagration.
A numerical measure of the explosion hazard potential of a dust as determined by multiplying the dust Ignition Sensitivity Index by its Explosion Severity Index.
The ability of a dust to take part in a closed explosion when dispersed in air at a suitable concentration and in the presence of an effective ignition source.
A method used for modeling the propagation of an initiating event through the sequence of possible incident outcomes. The event is represented graphically by a tree with branches from the initiating cause through the success or failure of independent protection layers.
A specific unplanned sequence of events composed of initiating events and intermediate events that may lead to an incident. See also Incident Sequence.
