2 Through-penetrations Estimating Through-penetrations 1. Find the total area of the opening (see Figure 1, Area of Joints or see Table 1, Areas of Circles). 2. Subtract the total area of penetrant(s) to find the total void area (see Table 2, Cross Sectional Area of Pipes). 3. Multiply the depth, or thickness, of the sealant or coating by the total void area to find the volume (see appropriate firestop system drawing). 4. Add the volume of caulk beads, if applicable (see Table 3, Volume of a Caulk Bead Around Pipes). 5. If penetration is passing through a wall, multiply total volume by 2 (for both sides of the wall).

NOTE: Figures shown above are for one side of wall only. A nominal 3 inch non-metallic pipe through a concrete floor requires 2 layers of wrap strip per the system design. 1. From Table 4, the first layer of wrap strip is inch long and the second layer is inch long. Therefore, the total length of wrap strip required is in. 2. If a restraining collar is required, a inch length is needed. 3. For wall applications, multiply these lengths by two. NOTE: Wrap strip applications also require sealant.

4 FlameSafe Bags and Pillows Estimating FlameSafe Bags and Pillows 1. Calculate the area of the opening. From this number, subtract area of any penetrants for the total area in inches squared. 2. Using Table 5A or 5B, for each bag or pillow size, multiply total square inches of opening by the percentage of opening each bag or pillow size will fill. Next divide this sum by the square inch coverage given for each bag or pillow size. Round all answers up to the nearest whole number (bag or pillow). This will yield the total number of each bag or pillow size to order. Table 5A FlameSafe Bags Estimating Guidelines Percentage of 7 In. Depth 13 In. Depth Catalog Opening Approx. Coverage Approx.

Multiply linear footage of joint by 12 to find length in inches. 2. Find the area of the joint or gap (see Figure 1). 3. Find the area of the overlaps on wall, floor and/or fluted deck, if applicable (see Figure 1). 4. Find the area of the flutes, if applicable (see Figure 1). 5. Add all the areas for total area. 6. Multiply the total area by depth or thickness of the coating or sealant for the total volume. 7. Multiply by 2 for both sides of the wall. in.
