It is 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.

• Provide the skills required to analyze an oil, gas or chemical processing facility and establish the degree and extent of the classified area.
• Provide an overview of the various codes and recommended practices developed for classifying facilities
• Provide guidelines on how to properly document your analysis and communicate to third parties who will rely on the information for  design,  construction and operating activities
• Introduce a number of alternative options for classifying facilities
• To predict the properties of flammable mixtures
• To perform fugitive emission and HVAC design calculations
• To properly document a hazardous area classification design
