From “facility siting” in a PHA to establishing emergency “assemble areas,” the methodology we use matters. Many of us use a RAGAGEP from The European Industrial Gases Association (EIGA) titled Methodology for Determination of Safety and Separation Distances. The “safety distance” is to provide a minimum separation that will mitigate the effect of any foreseeable event. The separation distance will also provide protection for the equipment from foreseeable external impacts such as roadway, flare, or activities outside the control of the operation, for example, a plant boundary and prevent it from escalating into a larger incident. Here is a peek at what this RAGAGEP can do for us…
