C. Steel Conduit - Nom 4 in. (102 mm) diam (or smaller) rigid steel conduit.
3. Firestop System - The details of the firestop system shall be as follows:
A. Packing Material - Min 4 pcf (64 kg/m3) mineral wool batt insulation firmly packed into opening as a permanent form.
Packing material to extend through entire thickness of concrete floor or wall except for recess at top surface of floor or both
surfaces of the wall to accommodate the required thickness of fill material.
B. Fill, Void or Cavity Materials* - Sealant or Putty - Min 1/2 in. (13 mm) thickness of sealant or putty applied within the
annulus, flush with top surface of floor or both surfaces of the wall. At point contact, apply min 1/4 in. (6 mm) bead at
penetrant/concrete interface on top surface of floor or both surfaces of the wall.
