      A.    Drawings and general provisions of Contract, including General and Supplementary Conditions
            and other Division 1 Specification Sections, apply to this Section.

1.2         SUMMARY

      This Section includes through-penetration fire-stop systems for the following types of fire-resistance-
            rated assemblies:
            Floors.
            Walls and partitions.
            Smoke barriers.
            Construction enclosing compartmentalized areas.

      Related Sections include the following:
            Division 15 Sections specifying duct and piping penetrations.
            Division 16 Sections specifying cable and conduit penetrations.

1.3         PERFORMANCE REQUIREMENTS

      F-Ratings: Provide fire-stop systems with F-ratings equaling or exceeding fire-resistance rating of
            constructions penetrated as determined per ASTM E 814.

      T-Ratings: Provide fire-stop systems with T-ratings required, as well as F-ratings, determined per
            ASTM E 814, where systems protect penetrating items with potential to contact adjacent
            materials in occupiable floor areas including, but not limited, to the following:
            Penetrations located outside wall cavities.
            Penetrations located outside fire-resistive shaft enclosures.
            Penetrations located in construction containing fire-protection-rated openings.
            Penetrating items larger than 4-inch-diameter nominal pipe or 16 sq. in. in overall cross-
                  sectional area.

      For fire-stop systems exposed to view, traffic, moisture, and physical damage, provide products that
             after curing do not deteriorate when exposed to these conditions both during and after
             construction.
             For piping penetrations for plumbing and wet-pipe sprinkler systems, provide moisture-resistant
                    fire-stop systems.
             For floor penetrations with annular spaces exceeding 4 inches in width and exposed to possible
                    loading and traffic, provide fire-stop systems capable of supporting floor loads involved
                    either by installing floor plates or by other means.
             For penetrations involving insulated piping, provide fire-stop systems not requiring removal of
                    insulation.

      For through-penetration fire-stop systems exposed to view, provide products with flame-spread indices
             of less than 25 and smoke-developed indices of less than 450, when tested per ASTM E 84.

      Surface Cleaning: Clean out openings immediately before installing through-penetration fire-stop
            systems to comply with written recommendations of fire-stop system manufacturer and the
            following requirements:
            Remove from surfaces of opening substrates and from penetrating items foreign materials that
                   could interfere with adhesion of through-penetration fire-stop systems.
            Clean opening substrates and penetrating items to produce clean, sound surfaces capable of
                   developing optimum bond with through-penetration fire-stop systems. Remove loose
                   particles remaining from cleaning operation.
            Remove laitance and form-release agents from concrete.

      Masking Tape: Use masking tape to prevent through-penetration fire-stop systems from contacting
           adjoining surfaces that will remain exposed on completion of Work and that would otherwise be
           permanently stained or damaged by such contact or by cleaning methods used to remove
           smears from fire-stop system materials. Remove tape as soon as possible without disturbing
           fire-stop system's seal with substrates.

3.3         INSTALLATION

      General: Install through-penetration fire-stop systems to comply with "Performance Requirements"
           Article and fire-stop system manufacturer's written installation instructions and published
           drawings for products and applications indicated.

      Clean openings immediately before installing fire-stop systems.
            Remove foreign materials that could interfere with adhesion of fire-stop systems.
            Remove laitance and form-release agents from concrete.
            Produce clean, sound surfaces capable of developing optimum bond with fire-stop systems.
                  Remove loose particles remaining from cleaning operation.

      Priming: Prime substrates when recommended in writing by fire-stop system manufacturer using that
            manufacturer's recommended products and methods. Confine primers to areas of bond; do not
            spill primers or allow them to migrate onto adjoining surfaces.

      Masking Tape: Use masking tape where required to prevent contact of fire-stopping with adjoining
           surfaces that otherwise would be permanently stained or damaged by such contact or by
           cleaning methods required to remove fire-stopping smears. Remove tape immediately after
           installation without disturbing fire-stopping seal.

      Accessories: Install accessories of types required to support fill materials during their application and
           in the position necessary to produce cross-sectional shapes and depths required to achieve fire
           ratings indicated.
           After installing fill materials, remove combustible forming materials and other accessories that
                  are not permanent components of fire-stop systems.

      Install fill materials for fire-stop systems by proven techniques.
              Fill voids and cavities formed by openings, forming materials, accessories, and penetrating
                      items as required to achieve fire-resistance ratings indicated.
              Apply materials so they contact and adhere to substrates formed by openings and penetrating
                      items.
              For fill materials that will remain exposed after completing Work, finish to produce smooth,
                      uniform surfaces that are flush with adjoining finishes.

      Identification: Identify fire-stop systems with pressure-sensitive, self-adhesive, preprinted vinyl labels.
              Attach labels permanently to surfaces of penetrated construction on both sides of each fire-stop
              system installation where labels will be visible. Include the following information on labels:
              The words: "Warning--Through-Penetration Fire-stop System--Do Not Disturb. Notify Facilities
                     Engineering of Any Damage."
              Contractor's name, address, and phone number.

            materials in which openings occur.

3.4         FIELD QUALITY CONTROL

      Testing Agency: Owner may engage a qualified independent testing and inspecting agency to perform
            field tests and inspections and to prepare test reports.
            Notify Owner's inspecting agency at least seven days in advance of fire-stop system
                    installations; confirm dates and times on days preceding each series of installations.

      Do not cover up fire-stop system installations that will become concealed behind other construction
           until inspecting agency and building inspector, if required by authorities having jurisdiction, have
           examined each installation.

      Inspecting agency will state in each report whether inspected fire-stop systems comply with or deviate
            from requirements.
