By Robert Schosker, Pepperl+Fuchs |

Understanding the different classification methods is necessary to better select the explosion-protection techniques that will be used Explosion protection is essential for many companies, and those companies have decision makers. But before any decisions can be made, there are some important factors one must consider. These factors include what is most efficient and economical, as well as knowing the basics of explosion protection; so the decision makers are headed in the right direction. We will highlight many of the different “things to know,” but first, let’s step back in time and take a look at the background of explosion protection.   Backdrop After World War II, the increased use of petroleum and its derivatives brought the construction of a great number of plants for extraction, refining and transformation of the chemical substances needed for technological and industrial development. The treatment of dangerous substances, where there exists the risk of explosion or fire that can be caused by an electrical spark or hot surface, requires specifically defined instrumentation located in a hazardous location. It also requires that the interfacing signals coming from a hazardous location are unable to create the necessary…
