How is Explosion Proof Enclosure different from Intrinsically Safe Protection Method?

There are some places like oil refineries, paint shops and chemical plants that are highly prone to the explosions. If not taken care of properly, a minor spark can set the entire place into ashes within no time. In order to avoid any such unpleasant situations in the areas where there is a high danger of explosions even with the small ignition, some important steps should be taken while placing these hazardous materials and even while designing the placement of these highly sensitive materials. By keeping some effective things in mind regarding the hazardous location Panel any accident can be avoided. Before doing anything else, it is important to identify the objects which are intrinsically safe and how they are different from those which are explosion proof.

• Let us first begin with, intrinsically safe technique Also known as the prevention method, intrinsically safe technique helps in avoiding the faults that can be caused because of malfunctioning of an electric circuit. Because of this highly effective technique, during the failure of an electric circuit, there can be no harm caused by ignition and explosions. The intrinsically safe technique is installed in such a way that no matter what the condition of temperature is, the circuit will not catch any ignition that can lead to an explosion. Buying the accessories for such panels is easy and cost-effective. For maintenance purpose and calibration, there is no need to turn off the power. Also, anyone can do its maintenance because it has simple circuits.

The intrinsically safe technique works perfectly when applied on a device which can be turned on a low power supply, because of this, it can be applied for very few appliances working with the low power of voltage. Also, when it comes to the difficult climatic condition, it is not 100% safe.

• Now let us talk about the Explosion Proof Enclosure:Also known as the Explosion Proof Panels, this is designed in a way that the explosion can take place within the area where the explosion is required. Used in applications with high voltage power, it is made up of materials with a mixture of heavy materials including, steel or aluminum. Now let us find of more about this technique.

It requires a sturdy enclosure, which is resistant to the explosions. When it comes to servicing, unlike the Intrinsically Safe Protection Method, this one requires expert attention with specific tools and it is not a task that can be done by just anyone. When it comes to weight the Explosion Proof Enclosure is very heavy.

• Limitations of Explosion Proof Enclosure includes:

It is very expensive and it can face serious troubles when exposed to moisture, the humid atmosphere, therefore, special care is needed for it. It is tough to install it because it is quite heavy. If regular inspections are not done, it is no longer safe to use.

Both the systems have some good points and some limitations too, choose the right one before you take any decision on whether to choose Explosion Proof Enclosure or Intrinsically Safe Protection Method.
