Course Overview

Hazardous areas comprise a large portion of most petrochemical plants, refineries, oil tank farms and many chemical plants. The instrumentation, control system and electrical systems used in these hazardous or classified locations is designed specially to prevent dangerous incidents. However, unfortunately many people are unaware of the methods of area classification, methods of protection, maintenance & installation of this kind of equipment.

Ignorance is dangerous and half knowledge can be even more dangerous, especially when one mistake can mean a fire or an explosion, leading to a loss of property or even worse loss of lives. Not to think of the lawsuits & filing for damages.

The solution is increasing awareness and training on hazardous areas and the instrumentation & control systems used in hazardous areas. And the quickest way to learn all about hazardous areas and the instrumentation & control systems used in hazardous areas.
