Intrinsic Safety
Intrinsic Safety
(OP)
This statement is found in one of our specifications for a diesel generator fuel oil transfer system. I am checking the spec. out to find omissions, errors, etc.
We are using NO. 2 fuel. The equipment, not including the day tank, is to be outside, in the yard. The day tank will be inside of a building.
'Electrical equipment used in the system shall be in accordance with NFPA 30, section 5-7, wherein it states "For areas where Class II or Class III liquids only are stored or handled at a temperature below their flash points, the electrical equipment may be installed in accordance with provisions of NFPA 70, National Electric Code, for ordinary locations..."'
Since I am not an intrensic safety expert I am just checking my facts. Does the above statement allow the exclusion of intrensically safe circuitry (including instrumentation)?
Thank you, everyone.

RE: Intrinsic Safety
This has been a few(?) years ago, so maybe someone else can verify.
If you don't get a better answer here in a day or so, you might post this question on the NFPA Code forum. Or you can red-flag your own post and ask that it be moved.
