A 1-Day Workshop or Part of 5-Day Package

Course Design and Objectives

Incorrectly specified electrical and mechanical equipment can provide a significant source of ignition for flammable atmospheres. The hazardous area classification process is designed to identify locations within a process plant where ignitable atmospheres exist, and to determine their likely extent. Using this information, the risk of ignition from equipment and devices in these areas can be minimized by either the specification of suitable equipment/devices, or relocating them to a safe, non-hazardous area.

Who Should Attend

Personnel (e.g., management, technical, operations and maintenance) involved with process safety, EH&S, process design, operations and maintenance from the chemical & processing industries, including bulk and finished pharmaceuticals, chemicals, petrochemicals, oil and gas, food, plastic & rubber, metals, textiles, wood & paper and agrochemicals who desire a more in depth understanding of how to evaluate and select electrical and non-electrical equipment for use in hazardous areas.

CEUs: 0.6 for standalone course or 3.0 for 5-day package
