Overview

The classification of hazardous areas is an integral part of the overall risk assessment process required under Regulation 7 of the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR) and Regulation 9 of the Prevention of Fire and Explosion and Emergency Response Regulations 1995 (PFEER). Its purpose is to define the extent, frequency and duration of an explosive atmosphere (the zone). The zone in turn defines the requirements for the selection of equipment and protective systems so as to control sources of ignition. Compliance with DSEAR is mandatory for any onshore operator handling dangerous substances and PFEER for any operator of fixed offshore installations.

Key topics

  • Introduction to DSEAR (2002) and in particular the requirements for area classification and selection of equipment to avoid ignition sources
  • The flammability of gases, vapours and dusts and how they relate to area classification
  • Introduction to BS EN 60079-10-1:2015 the British Standard for area classification relating to gases and vapours. The scope of this standard is addressed, in particular the grading of releases and the effect of ventilation
  • The course provides an overview of two widely used codes. EI15 edition 4 and SR25 edition 2 including syndicate exercises
  • Introduction to BS EN 60079-10-2:2015 the British Standard for area classification relating to dusts. The scope and use of this standard is addressed, complete with a syndicate exercise
