Into the world of IEC 60079-14

The World of IEC 60079-14

IEC 60079-14 is one of the most important International Standard ,specifying the requirements for :-

The Design

The Selection & The Physical Set-up

The Initial Inspection

of Electrical Installation in or associated with Explosive Atmospheres.

Let us walk-through the informative world of IEC 60079-14 . Each Section is represented by a graphic slide, with minimum narration .

Prevention should be the basic goal.

This is how we are introduced to IEC 60079-14. The prevention of explosion risk from the flammable materials should be sought first , by employing three important principles.

1. SUBSTITUTION

2. CONTROLLING

3. MITIGATION

The process of mitigation does not eliminate the risks of explosion completely. The basic idea is to suppress or cushion the effects of the explosion. Like an air-bag which does not prevent a car accident but cushions the effects of one and prevent the driver from probable injuries .

The process of Classification of the Hazardous Area into ZONES is governed by IEC Standard 60079-10 (IEC 60079-10-1 Explosive Gas Atmospheres & IEC 60079-10-2 Combustible Dust Atmospheres )

The classification process is an important step leading to the structured process of SELECTION OF EQUIPMENT

At this point (Section 4 ) IEC 60079-14 reminds the users to maintain a proper & structured documentation system , in multiple copies, with as much information as possible .
