Is it possible for a Hazardous Area (C1D2) to only be present for specific times during the day?
For example, if the potential for leaks only exist during 1 hour during the day, the C1D2 area classification would only exist for that 1 hour during the day. I know that analysis would also have to be done for any below grade or other accumulation points, but if not considering that, in general, can a C1D2 area only exist during the times of day that the hazard can occur.
I understand consistent care, procedure, and documentation would need to exist to facilitate this, but with all of that in place would it be a reasonable approach?
