Is there such a thing as a temporary obstruction to fire sprinklers?

I an a fire inspector at a chemical manufacturing facility. At this facility “plastic” tent material is used to enclose some operations to provide contamination control. This tent material is a heavy plastic and is supported by a metal skeleton. Thru research and testing I have determined that we will be considering the tent material to be an obstruction to the proper operation of our automatic fire sprinkler systems per NFPA 13 and 25.


My question, with reference to NFPA 13 and NFPA 25, is if there is any exemption for TEMPORARY obstructions and if so how long can an obstruction remain in place and still be considered temporary?
