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.
2.1 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
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
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
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
ASTM E-814 tested and Listed Systems Designs govern all installations
of Firestop Systems and Firestop
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
3.2.4 Provide temporary forming and packing as required.
3.2.5 Tool or trowel all exposed surfaces to smooth, neat and
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”
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
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
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.
