The objective of Hazardous Area Classification (HAC) analysis is to identify and classify 3-dimensional zones within a facility that handles flammable or combustible materials. HAC aims to minimize uncontrolled ignition by electrical equipment or hot surfaces, preventing fires, explosions, equipment damage, and loss of life.
Codes & Standards
Multiple codes and standards guide HAC, varying in criteria and approach. It’s essential to consider facility design and location before selecting the appropriate guidance document
Process Steps
Collect material hazard information, link process materials to equipment, and define HAC contours—combining individual results into a composite plan for safe and compliant facility design.
