DSEAR: Hazardous Area Classification for Gases and Liquids
HSE runs three different courses to help employers comply with
the Dangerous Substances and Explosive Atmospheres Regulations
- DSEAR: Gases and Liquids
- DSEAR: Hazardous Area Classification for
Gases and Liquids
- DSEAR: Controlling Dust Explosion
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.
DSEAR requires 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
The 'DSEAR: Hazardous Area Classification for Gases and Liquids'
course is aimed at those with some existing experience of DSEAR and
hazardous area classification, whereas the 'DSEAR: Gases and
Liquids' is an entry level course.
Delegates will be provided with information that will help them
- Understand how the regulations apply in relation to hazardous
- Know what standards are available for area classification
- Understand which area classification standards are most
applicable to them and understand which are applicable to their
- Be able to perform a straightforward area classification
- Be able to act as an intelligent customer when commissioning
hazardous area classification
What the course will cover
Delegates will be introduced to DSEAR and the classification of
hazardous substances and will look at the relevance of the
physical/chemical properties of gases, liquids and flammable mists
to area classification. The classification of hazardous areas by
zone will be explained, including the concept of a zone of
negligible extent (NE). Delegates will look at the importance of
ventilation in area classification and the concept of Vz based
methods. Delegates will look at hazardous area classification
standards and codes and be given an overview of what equipment to
use in classified areas. Finally, delegates will look at the
national and international standards and guidance commonly used in
area classification including practical examples of their use.
Who should attend?
This course is suitable for those who require
a detailed understanding of the process of hazardous area
classification, including process safety engineers, electrical
engineers and health and safety practitioners.
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 major roads and motorways, mainline train stations and
Manchester International Airport.
