Hazardous Area

Hazardous Area

Hazardous Area

(OP)
Hi there,

So far as i know definitions for classified areas have been defined by north americans as class I div I,II,... as opposed to Zone 0,1,.. of Europeans.

Anybody has heard anything like "Class I zone 0" which it seems to me a combination of both?

Any reference would be appreciated.

Regards,

RE: Hazardous Area

This is the US adaptation of the IEC Zone system. It is defined in Art 505 of the US National Electrical Code.

RE: Hazardous Area

Start with Google.  Search for "Zone 1 hazardous area" and surf from there.  You'll learn about Zone 0, 1 and 2 and much more.

To summarize the approximate equivalents:
   Class 1, Div 1 = Zone 1
   Class 1, Div 2 = Zone 2

Zone 0 is special. Only required for a constantly present hazard (like inside a fuel tank). It's included in Div 1 in the North American system.
