Intrinsic safety protects your plant against explosions

Explosions can be prevented by limiting the amount of electrical energy available in hazardous areas or by containing the situation using bulky, heavy devices called 'explosion-proof enclosures.' Limiting excess electrical parameters such as voltage and amperage (current) requires the use of energy-limiting devices known as 'intrinsically safe (IS) barriers.' Explosion-proof enclosures prevent or control explosive situations with brute force. They are heavy containers designed to hold an explosion inside. Electrical devices within explosion-proof enclosures can operate at normal power levels.
