Explosion proof enclosures are products that have an electric shock and have been exclusively created as a safety against inflammation hazards like detonations. These enclosures can be made of different varieties of components. Amongst these the commonly used components are aluminum, fiber glass and heavy duty steel. Explosion resistant enclosures are highly used at many important places like gas stations, oil refineries and paint factories. Explosions in the electrical networks are actually caused due the formation of the fire triangle. The fire triangle is formed by three elements. These are the spark or the ignition point, oxygen and fuel. When these three are mixed in a particular ratio, electrical explosion occurs.

To stay within the normal safety limits, the volume proportion of the fuel to the oxygen must not go beyond the volume ratio existing between the common explosive point of the fuel, and the source of ignition. On crossing the ratio, a spark in the energy occurs, causing ignition in the fire triangle mixture. The detonation proof enclosures aid in removing the potential explosion chance by removing all the ignition sources from the site. An enclosure that is internationally registered as having all explosion resistant traits must be used for the purpose. The explosion resistant enclosures work by resisting all the three internal forces which might otherwise gather in causing a fire blow ups.

An explosion resistant enclosure requires being in a proper layout and design. An organized design will verify that hot gases to pass through the ventilation systems which will allow the electric arrangement to remain cool, at a temperature below the dangerous ignition point, in case, there is some hazardous fuel. This is the reason why the enclosures are made using tough components like cast steel and aluminum. The enclosures also need to have ample flanges. The rims should be stuck to the finish and should posses a good tolerance.

The explosive resistant enclosures in coordination with the threaded cover will generate long and narrow paths. The potential hazardous hot gases will go through these thread tubes, giving up the heat to the metal, and in the process cutting the explosive force. However, the cover bolts of the enclosure must be well torque to the suggested value. Also, it is to be kept in mind that the ejection surfaces of the explosion proof enclosure remains protected throughout from marks. This is because, if the torque is not rightly generated and the projected surfaces are damaged, then the consequent hot gases will leak away. Besides, the risks of explosion will become more if the outside air of the enclosure is prone is explosion.

This is the reason why, the explosion proof enclosures are always present in nearly every kind of factory. Each electrical component has its own qualities and thus the enclosures needed for different functions are labeled consequently, also keeping in mind the environmental rules set up by the National Electrical Code or as per the IEC Standards.
