E.S.M. provides independent Hazardous Area Classification (HAC) services to identify and define areas where flammable gases, vapours, liquids or combustible dusts may be present, in accordance with Australian Standards and relevant legislative requirements.

HAC is a critical safety activity that informs equipment selection, inspection regimes and ongoing risk management. A sound HAC provides a defensible basis for managing ignition sources and demonstrating compliance with WHS obligations.

E.S.M.’s HAC services include:

  • Identification of flammable gases, vapours, liquids or combustible dusts and potential sources of release
  • Determination of hazardous area groups (e.g. IIA, IIB, IIC and IIIA, IIIB, IIIC) and zones (e.g. Zones 0, 1, 2 and 20, 21, 22)
  • Assessment of release characteristics and the influence of ventilation
  • Development of supporting classification documentation, including schedules and registers
  • Preparation of Hazardous Area Classification drawings and reports
  • Review of existing classifications for compliance with current standards

HAC is undertaken in accordance with relevant Australian and international standards, including the AS/NZS IEC 60079.10 series and applicable industry codes of practice.

E.S.M.’s HAC service is independent of detailed electrical or mechanical design, allowing us to provide objective, defensible classifications that support safe design, procurement and operation.
