Explosion is defined as an extreme increased in the energy of a system, which can be nuclear, mechanical or nuclear in an uncontrolled amount result in increasing in temperature and evacuation of gases. There are so many sources responsible for the explosions, some of them are increased pressure, nuclear reactions, leakage of gases, dust and others. In order to prevent these explosions, several types of prevention measures are being taken in to account at a time of designing products for electrical, mechanical, nuclear and chemical use and these devices/products are termed as explosion proof.
