If you work in hazardous locations and conditions, you would understand the need to promote safety and ensure that the risk of explosions is reduced. It is crucial that you eliminate one or more component of the ignition triangle to minimize the chances of an explosion. The 3 protection methods listed below are widely used in hazardous locations, in the process control industry:

Before we delve a little deeper and understand these techniques, let’s take a quick look at the role electrical enclosures.

Electrical enclosures are cabinets containing different electrical components such as switches, sockets, plugs, knobs, transformers and controls. These keep the surroundings safe from any kind of electrical hazard. Such enclosures are resistant to spark and shock and they have a high tolerance to extreme temperatures. They must be used in hazardous locations as they keep an interior explosion from spreading to the external environment and damaging life and property. Let’s see how they are relevant in the Containment method of protection:
