Hazardous Area Classification for Gases and Liquids
Live Online
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

- 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.
