  "description_excerpt": "Not Applicable.\n\nThe use of electrical devices in hazardous areas may lead to an increased risk of a fire or explosion triggered by the presence of the electrical device. For instance, an electrical device may serve as an ignition source in a hazardous area containing flammable gasses, vapors or dust. For this reason, electrical devices used in hazardous areas are often required to be certified according to the requirements specified in that particular jurisdiction. Further, often the types of protections required vary depending on the risks and hazards involved.\n\nHazardous environments have been categorized and regulated, but the specific classification, regulating, and governing thereof depends on jurisdiction. Electrical codes and standards for hazardous areas are generally understood as having two distinct paths. In North America, a ‘Class, Division’ system has been utilized, whereas other parts of the world use a ‘Zone System’ based predominantly on standards from the International Eletrochemical Commission (IEC) and European Community for Electrotechnical Standardization (CENELEC). A main difference is in the Zone system is that the level of hazard probability is divided into three ‘zones’ as opposed to two ‘divisions’\n\nThe types of hazardous environments are broken down into three classes, with each class focusing on different types of hazardous materials in the surrounding atmosphere.",
