2.03 FILL MATERIALS
A. Latex Sealants: Single-component latex formulations that do not re-emulsify after cure during
exposure to moisture.
B. Firestop Devices: Factory-assembled collars formed from galvanized steel and lined with
intumescent material sized to fit specific diameter of penetrant.
C. Intumescent Composite Sheets: Rigid panels consisting of aluminum-foil-faced intumescent
elastomeric sheet bonded to galvanized-steel sheet.
D. Intumescent Putties: Nonhardening, water-resistant, intumescent putties containing no solvents
or inorganic fibers.
E. Intumescent Wrap Strips: Single-component intumescent elastomeric sheets with aluminum foil
on one side.
F. Mortars: Prepackaged dry mixes consisting of a blend of inorganic binders, hydraulic cement,
fillers and lightweight aggregate formulated for mixing with water at Project site to form a
nonshrinking, homogeneous mortar.
G. Pillows/Bags: Reusable heat-expanding pillows/bags consisting of glass-fiber cloth cases filled
with a combination of mineral-fiber, water-insoluble expansion agents, and fire-retardant
additives. Where exposed, cover openings with steel-reinforcing wire mesh to protect
pillows/bags from being easily removed.
H. Silicone Foams: Multicomponent, silicone-based liquid elastomers that, when mixed, expand
and cure in place to produce a flexible, nonshrinking foam.
I. Silicone Sealants: Single-component, silicone-based, neutral-curing elastomeric sealants.
2.04 MIXING
A. Penetration Firestopping Materials: For those products requiring mixing before application,
comply with penetration firestopping system manufacturer's written instructions for accurate
proportioning of materials, water (if required), type of mixing equipment, selection of mixer
speeds, mixing containers, mixing time, and other items or procedures needed to produce
products of uniform quality with optimum performance characteristics for application indicated.
PART 3 - EXECUTION
3.01 EXAMINATION
A. Examine substrates and conditions, with Installer present, for compliance with requirements for
opening configurations, penetrating items, substrates, and other conditions affecting
performance of the Work.
B. Proceed with installation only after unsatisfactory conditions have been corrected.

3.02 PREPARATION
A. Surface Cleaning: Before installing penetration firestopping systems, clean out openings
immediately to comply with manufacturer's written instructions and with the following
requirements:
1. Remove from surfaces of opening substrates and from penetrating items foreign materials
that could interfere with adhesion of penetration firestopping materials.
2. Clean opening substrates and penetrating items to produce clean, sound surfaces capable
of developing optimum bond with penetration firestopping materials. Remove loose
particles remaining from cleaning operation.
3. Remove laitance and form-release agents from concrete.
B. Prime substrates where recommended in writing by manufacturer using that manufacturer's
recommended products and methods. Confine primers to areas of bond; do not allow spillage
and migration onto exposed surfaces.
3.03 INSTALLATION
A. General: Install penetration firestopping systems to comply with manufacturer's written
installation instructions and published drawings for products and applications.
B. Install forming materials and other accessories of types required to support fill materials during
their application and in the position needed to produce cross-sectional shapes and depths
required to achieve fire ratings.
1. After installing fill materials and allowing them to fully cure, remove combustible
forming materials and other accessories not forming permanent components of
firestopping.
C. Install fill materials by proven techniques to produce the following results:
1. Fill voids and cavities formed by openings, forming materials, accessories and
penetrating items to achieve required fire-resistance ratings.
2. Apply materials so they contact and adhere to substrates formed by openings and
penetrating items.
3. For fill materials that will remain exposed after completing the Work, finish to produce
smooth, uniform surfaces that are flush with adjoining finishes.
3.04 IDENTIFICATION
A. Wall Identification: Permanently label walls containing penetration firestopping systems with
the words "FIRE AND/OR SMOKE BARRIER - PROTECT ALL OPENINGS," using lettering
not less than 3 inches high and with minimum 0.375-inch strokes.
1. Locate in accessible concealed floor, floor-ceiling, or attic space at 15 feet from end of
wall and at intervals not exceeding 30 feet.
B. Penetration Identification: Identify each penetration firestopping system with legible metal or
plastic labels. Attach labels permanently to surfaces adjacent to and within 6 inches of
penetration firestopping system edge so labels are visible to anyone seeking to remove
penetrating items or firestopping systems. Use mechanical fasteners or self-adhering-type labels
with adhesives capable of permanently bonding labels to surfaces on which labels are placed.
Include the following information on labels:

Acceptance. If, despite such protection, damage or deterioration occurs, immediately cut out
and remove damaged or deteriorated penetration firestopping material and install new materials
to produce systems complying with specified requirements.
