【Area Classification Diagram】

We will show the result of HAC on the plot plan using the following two methods: “Superimposed display of 3D shapes” and “Display in plot plan and elevation.”

  1. Superimposed display of 3D shapes

    If you provide us with CAD data of piping diagrams, etc. that clearly show the locations of flanges, valves, etc., which are the sources of leakage, we can show the spatial shapes of hazardous areas as shown in the following figures.
    Even where there are a number of leakage sources comprising the hazardous area, by superimposing the areas of individual sources, you can recognize the hazardous areas of the entire facility, and clarify areas where non-explosion-proof equipment can be used according to the actual operation of the facility.
    It is also expected to be used in fields where spatial location information is required, such as safe flight planning of drones and the application of automatic flight functions in the future.

  2.  Display in plot plans and elevations
    In the case of many sources of leakage, the hazardous area can be displayed in plot plans and elevations for each type of leakage source, such as flanges and valves under the same operating conditions and fluids. The specific locations of the leakage sources are indicated using tables or other means.
    If leakage sources are few and limited, the hazardous area of each leakage source is displayed in plot plans and elevations.
    * Please refer to "Display in plot plans and elevations" below.
