Hazardous Area Classification (HAC) is a fundamental process safety study used to identify and categorize areas where flammable gases, vapors, or combustible dusts may form explosive atmospheres. Accurate classification is essential to ensure that electrical and mechanical equipment installed within these zones are designed and certified to prevent ignition.

PNA Risk Management performs comprehensive hazardous area classification studies based on internationally recognized standards including IEC 60079, API RP 505, and relevant industry guidelines. Our specialists systematically evaluate potential release sources, ventilation conditions, operating scenarios, and facility layouts to determine appropriate hazardous zones.

The outcome of the study includes detailed hazardous area zoning drawings, equipment suitability verification, and engineering recommendations that support safe facility design and operation. By ensuring correct equipment selection and installation practices, our HAC studies help organizations minimize explosion risks while maintaining compliance with applicable safety regulations.

Our experience spans across oil and gas processing facilities, petrochemical plants, storage terminals, chemical manufacturing operations, and energy infrastructure, providing clients with technically robust and regulator-ready deliverables.
