Existing construction is 3/4 of plaster on 6 nominal structural clay tile. Plaster is on one side only. I am looking for a penetration firestopping system with an F rating of 60 minutes that can be installed from one side if necessary, or both sides where conditions allow. Penetrations to be EMT or schedule 40 pipe, 2 diameter...

From the attached picture file, is having only mineral wool applied acceptable? Or does FS1 Max need to be applied also? The location is in an open parking garage.
