A one-day course intended for Professional Engineers and Design personnel who are responsible for the hazardous area classification design of industrial facilities incorporating flammable fluids. The course covers properties of flammable materials, standards and recommended practices, methods of area classification and documenting an area classification design.
Course Description
Learning Objectives:
To establish the degree and extent of a hazardous location for installations handling combustible dusts
To identify the appropriate hazardous area classification codes, standards and recommended practices for a given situation
To properly document a hazardous area classification design
Course Information
Course Includes:
