work on the site.
1.6.1.10 If an independent firestop contractor is engaged, a copy of that contractors Liability Insurance
Policy. (This clause is optional in some jurisdictions)
1.7 DELIVERY AND STORAGE
1.7.1 Deliver and store materials in their original unopened containers. Protect from damage and
environmental conditions as noted under manufacturer’s recommendations.
2. PRODUCTS
2.1 ACCEPTABLE PRODUCTS AND OR MANUFACTURERS
2.1.1 For the purposes of this specification there are NO GENERALLY APPROVED PRODUCTS OR
MANUFACTURERS. Only Firestop Systems tested to the ASTM E-814 Standard complete with Listed
Systems Designs showing their appropriate individual applications are acceptable.
2.2 MATERIALS
2.2.1 All Firestop Systems and Listed Systems Designs selected for use shall be listed and tested by a
Standards a recognized and accredited Third Party Testing Agency in accordance with ASTM E-814,
Standard Method of Fire Tests of Firestop Systems.
2.2.2 All Smoke Seal materials shall have been tested in accordance with ASTM E-84 Standard Method of
Testing for Surface Burning Characteristics of Building Materials and Assemblies and have a flame
spread classification of 25 or less.
2.2.3 Fire resistance ratings of installed Firestop Systems shall not be less than the fire resistance rating of the
surrounding Fire Separation or Firewall.



2.2.4 All Listed Systems Designs selected for use shall have a Smoke Seal incorporated within the ASTM E814
rated Firestop Systems.
2.2.5 All Firestop Materials that will come directly in contact with plastic pipe or plastic coated wire shall have
undergone Firestop Material compatibility testing by the Firestop Systems manufacturer and/or the pipe
or wire manufacturer.
2.2.6 Where moisture seals are required for floor penetrations in Operating Rooms, Morgues, and
Laboratories in Hospitals, Universities and Schools, the Firestop Materials selected must be compatible
with Formalin. (37% formaldehyde / 63% methanol)
2.2.7 All Firestop Materials and Smoke Seals shall have elastomeric characteristics to allow for building settling
and seismic movement.
2.2.8 All Firestop Materials and Smoke Seals shall be free of asbestos.
2.2.9 Site Firestop Systems must be installed in accordance with the Listed System Design limitations, unless

a technical evaluation is approved by one of the acceptable Third Party Testing Agencies.

2.2.10 All Listed Systems Designs used must provide an (F) and (T) rating.
3. EXECUTION
3.1 PREPARATION
3.1.1 Examine sizes and conditions of voids to be filled to establish correct thickness and installation of
Firestop Materials. If silicones are to be used ensure that substrates and penetrating item surfaces are
dry, clean and frost free.
3.1.2 Prepare surfaces in contact with Firestop Systems and Smoke Seals to manufacturer’s instructions.
3.1.3 Mask where necessary to avoid spillage and over coating onto adjoining surfaces; remove stains on
adjacent surfaces.
3.2 INSTALLATION
ASTM E-814 tested and Listed Systems Designs govern all installations of Firestop Systems and Firestop
Materials.

3.2.2 In all Firestop Systems that require mineral wool or ceramic fiber backer or filler materials, these
materials must be dry and free of other contaminants before, during and after installation of sealant
Firestop Materials. Alkaline water contamination of the backer or filler materials may cause corrosion of
metallic penetrating items.
3.2.3 Apply Firestop Systems and Smoke Seals in strict accordance with manufacturer’s instructions and
Listed Systems Designs to provide required temperature and flame rated seals, to prevent the passage
of fire and smoke, and where specifically designated, the passage of fluids.
3.2.4 Provide temporary forming and packing as required.
3.2.5 Tool or trowel all exposed surfaces to smooth, neat and tidy finish.
3.2.6 Notify Architect when completed installations are ready for inspection and prior to concealing or enclosing
Firestop Systems and Smoke Seals.
3.3 SERVICE PENETRATION FIRESTOP SYSTEMS
3.3.1 Firestop and smoke seal gaps and holes in all Fire Separation and Firewall construction through which
conduit, wire, cables, ductwork, piping and all other protrusions pass as a result of Work using an
appropriate Listed System Design identifying substrate type, penetrating material type, penetrating item
size, minimum and maximum annular space and overall “FTH” ratings.
3.3.2 In Combustible Construction (membrane GWB type) where the framing members are wood a Fire and
Temperature rise “FT” rating is required equal to that of the rating of the Fire Separation. Include
openings which have been formed and sleeved.

3.3.3 In Combustible Construction (membrane GWB type) where paper faced insulation or combustible vapor
and air barriers are incorporated within the separation a Fire and Temperature rise “FT” rating is required
equal to that of the rating of the Fire Separation.
3.3.4 In Combustible Construction (membrane GWB type), firestop and smoke seal all through penetrations of
the faces as above and firestop and smoke seal all penetrations that enter or exit (transverse) the edges
of one Fire Separation into another Fire Separation. (i.e. where the header or sill plate is penetrated in
the interior of a wall separation into the hollow ceiling or floor cavity of the adjacent separation).
3.3.5 In Combustible Construction (membrane GWB type), fire taping of service penetrations and HVAC duct
work is not acceptable unless a tested ASTM E-814 Firestop Systems is submitted.
3.3.6 Apply Firestop Systems at unpenetrated openings and sleeves installed for future use through Fire
Separations and Firewalls.
3.3.7 Install 1/4” to 3/8” bead of firestop caulking at interface of retaining angles around fire dampers, where
angles meet fire-rated assembly, and between retaining angles and fire damper, both sides of
penetration. At floor locations, sealant bead at top of assembly is adequate.
3.3.8 Where necessary, remove fiberglass insulation and replace with mineral wool insulation from insulated
pipes and ducts where such services penetrate a Fire Separation or Firewall unless the Listed Systems
Design permits such insulation to remain within the Firestop System.
