3.2 PREPARATION
A. Surface cleaning: Clean out openings and joints immediately prior to installing firestopping to comply
with recommendations of firestopping manufacturer and the following requirements:
B. Remove all foreign materials from surfaces of opening and joint substrates and from penetrating items
that could interfere with adhesion of firestopping.
C. Clean opening and joint substrates and penetrating items to produce clean, sound surface capable of
developing the optimum bond with firestopping. Remove loose particles remaining from cleaning
operation.
D. Priming: Prime substrate where recommended by firestopping manufacturer using the manufacturers
recommended products and methods. Confine primers to areas of bond; do not allow spillage and
migration onto exposed surfaces.
E. Masking Tape: Use masking tape to prevent firestopping from contacting adjoining surfaces that will

Remove tape as soon as it is impossible to do so without disturbing firestopping seal with substrates.
3.3 INSTALLATION
A. Install forming/ damming materials and other accessories of types required to support fill materials
during their application and in the position needed to produce the cross-sectional shapes and depths
required to achieve fire ratings of designated through-penetration firestop systems. After installing fill
materials, remove combustible forming materials and other accessories not indicated as permanent
components of firestop systems.
B. Install joint fillers to provide support of sealants application and at the position required to produce the
cross-sectional shapes and depths of installed sealants relative to joint widths that allow optimum
sealant movement capability and develop fire-resistance rating required.
C. Install sealant by proven techniques that result in sealants directly contacting and fully wetting joint
substrates, completely filling recesses provided for each joint configuration, and providing uniform,
cross-sectional shapes and depths relative to the joint width that provide optimum sealant movement
capability. Install sealants at the same time joint fillers are installed.
D. Tool nonsag sealant immediately after sealant application and prior to the time skinning or curing
begins. Form smooth, uniform beads of configuration indicated or required to produce fire-resistance
rating, as well as to eliminate air pockets, and to ensure contact and adhesion of sealant with sides of
joint. Remove excess sealant from the surface adjacent to joint. Do not use tooling agents that
discolour sealants or adjacent surfaces or are not approved by sealant manufacturer.
E. Cleaning
1. Clean off excess fill materials and sealants adjacent to openings and joints as work progresses by
methods and with cleaning materials approved by manufacturers of firestopping products and of
products in which opening and joints occur.
2. Protect firestopping during and after curing period of contact with contaminating substances or
from damage resulting from construction operations or other causes so that they are without
deterioration or damage at the time of Taking Over. If, despite such protection, damage or
deterioration occurs, cut out and remove damaged or deteriorated fire stopping immediately and

install new materials to produce firestopping complying with specified requirements.
3.4 FIELD QUALITY CONTROL

A. Examine sealed penetration areas to ensure proper installation before concealing or enclosing areas.

existing firestop systems already installed by other trades.
E. Manufacturer's Field Services: After the Initial Installation of Fire Stop System is complete, provide
destructive testing inspections to assure proper installation of the application, submit findings in writing
indicating whether or not the installation of the tested system identified was installed correctly. This
cannot be treated as an inspection, but this service is more to see that the systems included in the
submittal are being implemented on Site.
3.5 IDENTIFICATION AND DOCUMENTATION

A. The Contractor is to supply documentation (to be included in submittal) for every single application
addressed. This documentation is to identify each penetration and joint location on the entire Project.

permanently to surfaces of penetrated construction on both sides of each firestop system installation
where labels will be visible to anyone seeking to remove penetrating items or firestop systems. Include
the following information on labels:
1. The words: "Warning - Through-Penetration Firestop System - Do Not Disturb. Notify Building
Management of Any Damage."
2. The Contractor's Name.
3. Firestop system reference.
4. Firestop system manufacturer's name.
