firestopping work has been inspected and found to be applied
according to the manufacturer's recommendations and the specified
requirements.
1.3
GENERAL REQUIREMENTS
Firestopping shall consist of furnishing and installing tested and listed
firestop systems, combination of materials, or devices to form an effective
barrier against the spread of flame, smoke and gases, and maintain the
integrity of fire resistance rated walls, partitions, floors, and
ceiling-floor assemblies, including through-penetrations and construction
joints and gaps. Through-penetrations include the annular space around
pipes, tubes, conduit, wires, cables and vents. Construction joints
include those used to accommodate expansion, contraction, wind, or seismic
movement; firestopping material shall not interfere with the required
movement of the joint. Gaps requiring firestopping include gaps between
the curtain wall and the floor slab and between the top of the fire-rated
walls and the roof or floor deck above.
1.4
DELIVERY AND STORAGE
Materials shall be delivered in the original unopened packages or
containers showing name of the manufacturer and the brand name. Materials
shall be stored off the ground and shall be protected from damage and
exposure to elements. Damaged or deteriorated materials shall be removed
from the site.
1.5
INSTALLER QUALIFICATIONS
The Contractor shall engage an experienced Installer who is:
a.
FM Research approved in accordance with FM AS 4991, or
b. Certified, licensed, or otherwise qualified by the firestopping
manufacturer as having the necessary staff, training, and a minimum of 3
years experience in the installation of manufacturer's products per
specified requirements. A manufacturer's willingness to sell its
firestopping products to the Contractor or to an installer engaged by the
Contractor does not in itself confer qualification on the buyer. The
Installer shall have been trained by a direct representative of the
manufacturer (not distributor or agent) in the proper selection and
installation procedures.

insulating, unless insulation meets requirements specified for
firestopping. Firestopping materials at building joints and construction
gaps shall be applied prior to completion of enclosing walls or assemblies.
Cast-in-place firestop devices shall be located and installed in place
before concrete placement. Pipe, conduit or cable bundles shall be
installed through cast-in-place device after concrete placement but before
