Hazardous Area Classification
Hazardous area classification is the process of identifying where a flammable gas cloud or combustible dust cloud could occur and then assigning those locations a zone and extent so the appropriate equipment and controls, in addition to the necessary work practices are used.
Hazardous area classification answers three practical questions:
-
Where could an explosive atmosphere exist?
-
How often / how long could it exist?
-
How far could it spread?
The outcome of the Hazardous Area Classification process usually produces:
-
A zoning drawing showing boundaries.
-
A basis of safety describing releases, ventilation, and assumptions.
-
Equipment requirements: EPL/category, temperature class, dust group, IP rating.
HazardZoneExpress
HazardZoneExpress is a new software from Advanced Analysis, designed for rapid hazardous area zoning and equipment marking checks. It is designed to check electrical equipment compliance according to IEC60079, AS/NZS60079 and ATEX/DESAR requirements.
Hazardous Area Classification Workflow and Features
Simply load a PDF, mark zones visually, import an equipment checklist CSV, and place equipment directly onto the drawing to instantly show Placed Zone and Compliance status.
Key features
-
PDF Markup (Zones on the drawing)
Draw and export zone areas directly on your PDF (rectangles/circles), with a clear legend. -
Auto Zone by Hours (or manual)
Use “Auto (by hours)” to color-code zones from exposure time, or switch to manual selection. -
Equipment List + Placement Workflow
Import your checklist CSV, click an item, then place it on the PDF to record its location and zone. -
Instant Compliance Result
Each placed item shows Compliance (YES/NO/N/A) and Placed Zone, based on your marking rules. -
Export Outputs
-
Export marked-up PDF (Acrobat-editable annotations)
-
Export the full equipment list (including Compliance + Placed Zone) to CSV
-
Typical workflow
-
Open PDF (site plan / room layout / GA drawing)
-
Mark zones (Dust or Gas) using Auto-by-hours or manual colors
-
Import equipment checklist CSV
-
Select an item and place it onto the PDF
-
Review Compliance and Placed Zone in the table
-
Export PDF and Export CSV for reporting and audit trails
