The need to protect computers in hostile environments (flammable gases, vapors, or combustible dust) is extremely important. Commonly referred to as **“hazardous locations,”** these areas can contain flammables in concentrations that could quickly ignite if exposed to an electrical spark, flame, or sufficient heat. The lack of proper protection could result in the ignition of these explosives, which may lead to a loss of property or even a life. ![itsenclosures_hazardous_purge_control](https://blog.itsenclosures.com/hs-fs/hubfs/itsenclosures_hazardous_purge_control.jpg?width=150&name=itsenclosures_hazardous_purge_control.jpg "itsenclosures_hazardous_purge_control")Hazardous locations are rated by Classification, Division and Group. Class I refers to a gas atmosphere and Class II refers to a dust atmosphere. For more information on the classifications and divisions, please visit: **[Defining Hazardous Area Computer Enclosures](https://blog.itsenclosures.com/blog/defining-hazardous-area-computer-enclosures).** It is common practice to protect vital electronics in a purged computer enclosure, because they protect electrical circuits by changing the atmosphere from hazardous to non-hazardous. This process is accomplished by employing the technique of purging, and then, pressurizing an airtight enclosure with inert gas or clean air, usually compressed air from a known non-hazardous area. By using a purged enclosure, non-rated electrical devices, such as computers, monitors and peripheral ![itsenclosures_hazardous_purge_control_z_purge](https://blog.itsenclosures.com/hs-fs/hubfs/itsenclosures_hazardous_purge_control_z_purge.jpg?width=151&name=itsenclosures_hazardous_purge_control_z_purge.jpg "itsenclosures_hazardous_purge_control_z_purge")equipment, can be used in a hazardous area. Normally, these devices would be unsuited for such a harsh environment. Before deciding on an **[enclosure solution](https://blog.itsenclosures.com/blog/4-steps-to-selecting-a-computer-enclosure)** for a hazardous factory or industrial area, make sure that the proper research is completed to determine the type of enclosure that can be purged. Computer enclosures that feature gasketing and multiple door fasteners are ideal for maintaining a properly sealed cabinet.  It is also recommended that the enclosure meet the National Electrical Manufacturer’s Association rating of NEMA 4 or **[NEMA 4X](https://blog.itsenclosures.com/blog/3-considerations-for-choosing-a-nema-4x-enclosure)**.
