Hazardous Area Classification (HAC)

Hazardous Area Classification (HAC) is a systematic process used to identify and categorize areas where explosive atmospheres may occur due to the presence of flammable gases, vapors, dust, or fibers. The main goal of HAC is to define zones based on the likelihood and duration of the hazardous substance being present, so that appropriate safety measures, equipment, and installation practices can be applied to prevent ignition and ensure safe operation.

What We Do in Hazardous Area Classification

Our Hazardous Area Classification (HAC) services provide a comprehensive approach to identifying and categorizing areas where explosive atmospheres may occur due to flammable gases, vapors, or dust. We begin with a thorough site survey and data collection to understand your facility’s processes and environment. Based on this information, we perform a detailed risk assessment to classify hazardous zones according to international standards such as IEC, NEC, and ATEX. We prepare clear HAC drawings that integrate with your plant layout, helping you visualize the classified areas. Additionally, we offer expert guidance on selecting appropriate explosion-proof or intrinsically safe equipment to ensure operational safety. Our services include comprehensive documentation and reporting to support regulatory compliance and audits. We also provide training for your personnel to enhance awareness and safe practices in hazardous zones. Finally, we offer periodic reclassification and updates to accommodate any changes in your processes or regulations, ensuring ongoing safety and compliance.
