What Does Explosion Proof Protection Mean?
Explosion Proof Protection originated from the techniques or equipment defined by the National Fire Protection Association (NFPA). The NFPA started publishing the National Electric Code (NEC®) which has several definitions for different kinds of protection methods to be used if designing productions that will be used in a hazardous environment. These are dust ignition proof, dust tight, purged/pressurized, hermetically sealed, intrinsically safe and explosion proof. All of the components added to a hazardous environment must meet the criteria set by these definitions.
