Hazardous Area Classification for Gases and Liquids

Book Course

28 February 2023

HSE runs three different courses to help employers comply with the Dangerous Substances and Explosive Atmospheres Regulations (DSEAR).

While there is some overlap between the courses delegates can attend one or more courses depending on which area of DSEAR they are interested in.

Introduction

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) require that areas where accidental releases of dangerous substances could occur are identified and classified according to the likelihood of the formation of a flammable atmosphere. Within classified areas sources of ignition should be controlled. This course is designed to provide delegates with the knowledge to carry out straightforward hazardous area classification in accordance with commonly used standards or to act as an intelligent customer when contracting others to deliver this role.

The course covers

CPD Certified

  • The classification of hazardous substances
  • The relevance of the physical/chemical properties of gases, liquids and mists to area classification
  • The classification of hazardous areas by zone, including the concept of a zone of negligible extent (NE)
  • The importance of ventilation in area classification and the concept of Vz
  • The Quadvent approach to area classification
  • The national and international standards and guidance commonly used in area classification including practical examples of their use
  • An introduction to equipment for use in explosive atmospheres

Who should attend

This course is suitable for those who may be asked to carry out hazardous area classification as part of a DSEAR assessment including process safety and electrical engineers, and health and safety practitioners.

This course is suitable for those who require a more detailed understanding of the process of hazardous area classification including process safety and electrical engineers, and health and safety practitioners.

For a higher level introduction to hazardous area classification the DSEAR - Gases and Liquids course would be more appropriate.

Venue

The course will be run at the HSE Science and Research Centre in the spa town of Buxton. Buxton is in the heart of the Peak District and has good links to mainline train stations and Manchester International Airport. This course can be run at your site or local area by arrangement.
