Overview

The classification of hazardous areas is an integral part of the overall risk assessment process required under the Dangerous Substances Explosive Atmospheres Regulations 2002 (DSEAR). Its purpose is to defne the extent, frequency and duration of any occurrence of an explosive atmosphere (the zone). The zone in turn defines the requirements for the selection of equipment and protective systems so as to prevent sources of ignition. Compliance with DSEAR regulations is mandatory for any operator handling dangerous substances.

Key topics

  • introduction to the risk assessment requirements under 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 BSEN60079-10, 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
  • BSEN60079-10 covers the use of industry codes – the course provides an overview of two popular codes including a syndicate exercise
  • introduction to the scope and use of BSEN61241-10, the British standard for area classification relating to dusts, including a syndicate exercise

Outline the course programme

Day 1

  • introduction to the risk assessment requirements under DSEAR (2002) and how area classification plays an integral part
  • the flammability of gases, vapours and dusts and how they relate to area classification
  • equipment for use in hazardous areas
  • new equipment, existing installed equipment, BS EN 60079-10 (Gases & Vapours)
  • British standard ‘classification of hazardous areas’, introduction to this standard scope and use procedures of an ‘Industry Code’ (1) the Institution of Gas Engineers (IGE/SR/25) ‘Hazardous area classification of natural gas installations’ scope and use syndicate exercise using IGE/SR/25

 

Day 2

  • use of an 'Industry Code' (2)

  • 'area classification code for installations handling flammable fluids' overview structure
  • BS EN 61241-10 (Dusts)
  • British standard 'Classification of areas where combustible dusts are or may be present'
  • introduction to this standard procedure syndicate exercise using BS EN 61241 10
