ELECTRICAL EQUIPMENT IN HAZARDOUS AREA & CLASSIFICATION

Ref No: 2015034

INTRODUCTION
This course provides delegates with an understanding of the hazards involved in using electrical equipment in potentially explosive atmospheres. It is based on the newly adopted international IEC 79 Series of Standards that are now replacing the older national standards and are directly applicable to most countries in the world (including North America). Explosion-proof installations can be expensive to design, install and operate. The wider approaches described in these standards can significantly reduce costs whilst maintaining plant safety. The book explains the associated terminology and its correct use. It covers from area classification through to the selection of explosion-protected electrical apparatus, describing how protection is achieved and maintained in line with these international requirements. Standards require that engineering staff and their management are trained effectively and safely in hazardous areas and this book is designed to help fulfill that need.
.
OBJECTIVES
Upon the successful completion of the course, participants will gain the following from this course:
• A good understanding of terminology used with hazardous areas
• An understanding of the hazards of using electrical equipment in the presence of flammable gases, vapors and dusts
• A basic knowledge of explosion protection to IEC Standards
• The ability to do a simple hazardous area classification
• Details of the types of apparatus that can be used in a given hazardous area
• How to design and install safe working systems in hazardous areas
• An understanding of the safety and operational aspects of hazardous areas
• A knowledge of the system limitations in using hazardous areas protection
• A brief review of the key areas of the national codes of practice.
You will need a basic understanding of instrumentation and electrical theory for the course to be of greatest benefit. No previous knowledge of hazardous area installation is required
