Hello frens
Can anyone suggest that what are the best practices for thermography in classified areas? Is our normal camera can be used in classified areas? My main intension is to do thermography of Motors of IIB & IIC Areas.

Thanks & Regards

I have a couple of classified areas that I survey and in both cases the customer requires that I show them all photos and thermal images before I leave their site. I have had cases were I was asked to delete an image and take a closer shot to eliminate capturing background. You should be able to discuss your concerns with the customer and get their security based requirements.

Joe,

I believe he is talking about explosion classes, not security.
I think there are only a few intrinsically safe cameras out there.

You may be right, I wasn't thinking along those lines. Are IIB & IIC levels of explosive potential?

I'm not sure what they are really. In the US, explosion proof is usually Class. I, Div. I, and Class I Div. II.

I found this info on the web:Seems to be saying the same thing, just a different way of nomenclature.

Group I
For application in below ground installations (mines) where methane (firedamp) and coal dust may be present.

Group IIA
For application in above ground installation where hazards due to propane may exist. This group most closely matches the North American Group D.

Group IIB
For application in above ground installations where hazards due to ethylene may exist. This group most closely matches the North American Group C.

Group IIC
For application in above ground installations where hazards due to hydrogen or acetylene may exist. This group most closely matches the North American Groups A and B.

Thanks for the info Dave.

You are very right Mr Dave
we have Many MV Motors Instaleld in Classified Areas. Any One have Experience with Thermography of Motors in Classified Areas , then please share ? What type of Camera they are using? Can our normal camera (like Building thermography) be used in classified areas?)

You can now get EX rated cameras (at a price) that will allow you into controlled zones without a problem.
I use a Flir E45, I do take it into controlled zones but I have to have a permit to do so and while I am using it I have someone constantly testing the atmosphere for explosive concentrations of gas.
I don't think that a building camera is suitable for looking at motors, not because of the controlled zone issue but because of it's range.
