COURSE NAME:Instrument Safeguarding


This course can be scheduled at your convenience, to request this course please click here

There are several ways to provide the means of prevention of the potential risks of equipment, where Many factors determine the most appropriate types of protection needed, and these factors: the type of operations, the size and shape of the torch, by treating and handling, the site of the stomach, the type of material used.



Training in Process Safeguarding (Safety in Process Design) covers a wide range of subjects with many applications in hydrocarbons and chemical processing. As the name suggests, it addresses the process engineering and safeguarding aspects of processing equipment/units. The process design safety orientation of the participant results in safe process designs.
