Hazardous Area Instrumentation Training Course - Electronic Download
Note: After purchase, you will be sent a link where you can download the training course.
This is a self paced training course which covers all aspects of instrumentation and automation systems used in hazardous (classified) locations.
Typically facilities in oil & gas, refining, petrochemical and chemical processing have areas which contain explosive or hazardous atmospheres. The instrumentation and automation systems used in these areas must be designed to ensure that they work safely at all times. Engineers working on these systems need to know about hazardous area classification, temperature and material classification, different methods of explosion protection, certification, testing and maintenance.
This course covers all the above topics. It consists of six modules as given below:
Basic Concepts - History and definitions, basic concepts about hazardous locations, Fire triangle, LEL/UEL, Flash Point, autoignition, etc.
Classification - Area classification, material and temperature classifications, Different standards North American (NEC) and European (IEC), dust ignition, step by step guide to classification of your plant / facility.
Protection Methods - Different methods of protection including how each method works.This covers explosionproof / flameproof, Intrinsic safety, (including designing a typical loop using principles of Intrinsic safety ), Increased Safety, Pressurization & purging, etc.
Fieldbus Applications - Discusses various ways of implementing Fieldbus installations in hazardous areas. Concepts of FISCO and FNICO.
Certification - Certification labs and statutory bodies, labeling on instruments, how to read labels & markings, etc.
Maintenance - Guidelines for inspection and maintenance, how to preserve the integrity of your installation.
There are about 150 topic pages with graphics, animations and actual photographs which explain all these concepts very clearly.
Here's what the course covers in detail:
