The publications listed below form a part of this specification to the extent referenced. The publications are referred to in the text by the basic designation only.
SUBMITTALS
Manufacturer's Catalog Data
a. Firestopping, include composition and performance characteristics.
Provide manufacturers name, address and phone/fax numbers.
DELIVERY, STORAGE, AND HANDLING
Deliver materials in the original unopened packages or containers showing name of the manufacturer and the brand name. Store materials off the ground and protect from damage and exposure to elements. Remove damaged and deteriorated materials from the site.
MATERIAL
Provide asbestos-free firestopping material capable of maintaining an effective barrier against flame, gases and temperature. Provide material that is non-toxic.
FIRE HAZARD CLASSIFICATION
Material shall meet stability "R", resistance "E" and thermal insulation "I" per D.M. dated 30.11.1993, D.M. dated 30.11.1983 and D.M. dated 26.08.1984. Material shall meet classifications of REI 60, REI 120 or REI 180 as appropriate for the specific location installation.
MANUFACTURES
Firestopping shall be manufactured by any of the following manufactures meeting the specification requirements, or by approved equal.
FIRESTOPPING MATERIAL LOCATION
Provide firestopping material in the following locations:
a. Duct, cable, conduit, and piping penetrations through fire rated above grade floor slabs, partitions, or walls.
b. Openings between walls and ceilings of time-rated assemblies.
c. Penetration of vertical service shafts.
d. Openings and penetrations in enclosures with time-rated fire doors.
e. Other locations indicated.
PREPARATION
Coordination
Coordinate the work with other trades. Apply firestopping materials, at penetrations of pipes and ducts, prior to insulating, unless the insulation meets the requirements specified for firestopping.
Surface Preparation
Remove dirt, grease, oil, loose materials, rust, or other substances that may affect proper fitting or the required fire resistance from surfaces in contact with firestopping materials, unless otherwise directed by the manufacturer's instructions.
INSTALLATION
Install at locations shown or specified in accordance with manufacturers' printed instructions.
Voids Filling
Completely fill voids at the firestopping surface. Firestopping for filling voids in floors in which the smallest dimension of the void is 100 mm or more shall support the same load that the floor was designed to support or shall be protected by a permanent barrier to prevent loading or traffic in the firestopped area.
Insulated Pipes and Ducts
Insulate pipes and ducts penetrating fire-rated floors and walls with materials providing the same performance as the firestopping material. Extend this material a minimum of 150 mm on each side of the opening.
Fire Dampers
Furnish and install fire dampers in ducts and penetrations of time-rated construction in accordance with the requirements of “Ductwork and Ductwork Accessories”.
Electrical Cables or Conduits
Firestopping at all wall and floor penetrations.
FIELD QUALITY CONTROL
To ensure proper installation, firestopped areas shall not be covered or enclosed until inspection is complete and approval has been received.
