ATEX for Biogas & Wastewater Plants
Independent ATEX biogas support — hazardous area classification, EPD and Ex inspection to IEC 60079-17 for methane/biogas around digesters, gas holders, upgrading and wastewater treatment, where flammable gas can form explosive atmospheres.

Flammable gas around digesters
Biogas (largely methane) forms around digesters, gas holders, upgrading and sludge handling, and wastewater processes can release flammable gas too. These are classic gas hazardous areas — zoning, gas detection and correct Ex equipment are the controls, verified by inspection.
What I check at biogas & wastewater sites
Gas zones
Digesters, gas holders, upgrading and sludge areas — gas classification (Zone 1/2).
Ex equipment & detection
Motors, blowers, instrumentation and gas detection — type of protection and condition to IEC 60079-17.
Earthing & EPD
Bonding, static control and a current EPD that matches the plant.

Frequently asked questions
Which zones apply to biogas?
Typically gas Zones 1 and 2 around digesters, gas holders and upgrading — confirmed by classification.
Is gas detection part of the inspection?
Yes — fixed gas detection and the associated Ex equipment are checked under IEC 60079-17.
