On completion of this course delegates will be aware of all the relevant terminology of the hazardous area field and will understand the parameters of hazardous materials relevant to area classification assessments. Delegates will able to carry out basic hazardous area classification assessments using the techniques contained within BSEN60079-10, IP-15 and SR25 for indoor and outdoor situations using direct example and point source release methods of assessment.

This course includes three methods / sector standards of assessment and therefore provides delegates with a broader knowledge of area classification and the ability to apply them to many more situations within industry, including natural gas and the petrochemical industry.
