Hazardous Area Classification for Gas Utilities
A one-day course designed for professional Engineering, Design, Construction and Maintenance Personnel who are responsible for defining the degree and extent of classified locations in Gas Utility Installations and Facilities. The course specifically covers natural gas installations and the industry standards applicable.
- To establish the degree and extent of a hazardous location for typical Utility installations handling natural gas.
- To identify the appropriate hazardous area classification codes, standards and recommended practices for a given situation.
- To perform fugitive emission and HVAC design calculations.
- To properly document a hazardous area classification design.
