Hazardous Area Classification

Minimise risks at your site and keep your people safe

Our experienced process engineers and accredited dangerous goods consultants can manage the entire Hazardous Area Classification (HAC) process from start to finish, improving the safety of your operation and ensuring compliance with hazardous area acts, regulations and standards including the AS/NZS 4761 series. Our experience extends across manufacturing, mining and processing facilities that generate, handle and store flammable gases, vapours, liquids and combustible dusts.

Talk to us about:
  • Hazardous area zone identification and classification for gas and dust atmospheres
  • Engineering and drafting of hazardous area drawings to support site classification
  • Preparation of hazardous area verification dossiers
  • Installation verification auditing for installed equipment
  • Facilitation of hazardous area risk assessments

Computational Fluid Dynamics (CFD)

Different applications of CFD modelling

In special circumstances, we can take hazardous area assessment to the next level through Computational Fluid Dynamics (CFD). CFD modelling and simulation allows a more detailed review of the probable extent of hazardous zones. This can add substantial value over HAC alone, including the potential to enable significant long-term cost benefits where process specific zoning applies. Our process engineers have the skills to identify when standard HAC one-dimensional calculations may be insufficient. The needs-analysis process includes a detailed cost-benefit analysis to ensure an investment in CFD modelling would be worthwhile. Our process engineers provide all the detailed information required to prepare appropriate CFD models.
