Designing, maintaining and operating of Instrumentation and Control Systems in Hazardous Areas, requires specialized knowledge which ensures that the system work safely, without being sources of ignition themselves. There are many ways in which explosion protection of the system is achieved. These include protection methods like Explosion proofing, Intrinsic Safety, Increased safety, Pressurization, which have to be understood in-depth by the Instrumentation and Control engineers and technicians who are responsible for designing & maintaining the system.
This course is designed to help students to understand the basic principles of hazardous areas, classifying hazardous materials, understanding the nature of the risk and the necessity to eliminate sources of ignition.
After completing this course, students will have significant knowledge on the installation and maintenance of the different types of equipment, increased safety, intrinsic safety etc.
