HAC

Introduction:

  • The hazardous area is defined as a three-dimensional space in which a flammable atmosphere may be expected to be present at such frequencies as to require special precaution for the control of potential ignition sources including fixed electrical equipment.
  • As part of HAC services, iFluids analyses and classifies the environment where explosive gas atmospheres may occur, to facilitate the proper selection, installation and operation of equipment to be used safely in that environment.
  • We systematically review the plant and operations and based on the results define hazardous area zones where potentially explosive atmospheres may develop and persist. The zone classification defines the standard of equipment required to effectively control ignition sources in the area.

 

Objectives:

  • The determination of type of hazardous zone
  • Extent of the zone.

 

Standards Referred:

  • EN 60079-10-1 (Gases and Vapours)
  • EN 60079-10-2 (Combustible Dusts)
  • IGEM SR/25 (Natural Gas)
  • IP15 , API RP 500 and 505
  • Industry Codes
