    That is a good idea. BTW it's Section 501.125(B). The Article is 501.

    You might also try for a Formal Interpretation. It is a lot tougher to get, but it can be quicker if successful.

    Division 2 does not require that the equipment not be able ignite a flammable atmosphere under ALL possible conditions, just that it not do so under normal operating conditions.


    Besides unless it is an old motor cooling fans will be non ferrous anyway.
