  4. 4. ©2015–HervéBaron HERVE BARON Hazardous area classification  The purpose of area classification is to identify the extent of the area made hazardous due to the presence of explosive atmosphere and to classify the identified hazardous area on the basis of likelihood and type of flammable release expected to be present.  Outcome:  Specify explosion protection of instruments and electrical apparatus according to their location.  Ensure that sources of ignition area are segregated from sources of flammable gas,  Select the location of clean air inlets for ventilation systems or other safety requirements,  Design the Plant layout to minimize classification of access roads.
  5. 5. ©2015–HervéBaron HERVE BARON Hazardous area classification  The following information is required to enable correct selection of electrical equipment and instruments suitable to the area in which they are to be located:  Zone of hazardous area,  Gas group of material,  Maximum permissible surface temperature (Temperature Class).
  6. 6. ©2015–HervéBaron HERVE BARON Hazardous area classification  The following information is required to enable correct selection of electrical equipment and instruments suitable to the area in which they are to be located:  Zone of hazardous area,  Zone 0 location is a location at which ignitable concentration of flammable gases or vapours are present continuously or for long periods of time.  Zone 1 location is a location at which ignitable concentration of flammable gases or vapours are likely to exist under normal operating conditions,  Zone 2 location is a location at which ignitable concentrations of flammable gases or vapours are not likely to occur in normal operation and if they do occur will exist only for a short period Ref: API RP 505 Recommended Practices for Classification of Locations for Electrical Installations at Petroleum Facilities classified as Class I, Zone 0, Zone 1 and Zone 2 (1997 Edition).
  7. 7. ©2015–HervéBaron HERVE BARON Hazardous area classification  The following information is required to enable correct selection of electrical equipment and instruments suitable to the area in which they are to be located:  Zone of hazardous area,  Gas group of material,
  8. 8. ©2015–HervéBaron HERVE BARON Hazardous area classification  The following information is required to enable correct selection of electrical equipment and instruments suitable to the area in which they are to be located:  Zone of hazardous area,  Gas group of material,  Maximum permissible surface temperature (Temperature Class).

  22. 22. ©2015–HervéBaron HERVE BARON Hazardous area classification WRAP-UP Hazardous area classification is done in 3 steps:  Define the classification philosophy, i.e, specify which code will be applied, e.g., API RP 505 (this is usually done part of the Safety Concept)  Issue of Hazardous Equipment table identifying properties of fluids handled (flammability of gases, flash point of liquids) as well as extent of hazardous area created by the various process streams as a function of the nature of fluid handled and its conditions (pressure, temperature)  Draw the hazardous area envelopes
