BASIC USE:
Nelson FSP is a firestop product in putty form. It is completely premixed
and ready to use and can be hand pressed into place forming an immediate
fire seal. When exposed to fire the intumescent material will expand
to seal voids caused by deteriorating cable jackets, maintaining the
seal and preventing the passage of fire or smoke to adjacent rooms.
COMPOSITION AND MATERIALS:
Nelson FSP is a one-part composition, similar in consistency to glazing
putty. Ingredients are a combination of organic and inorganic materials,
blended into a hand moldable finished product. It is possible to reuse
the same material when adding or changing penetrating items because
the putty does not set up. There are no disagreeable toxic or hazardous
fumes released during installation, and curing time is not required.
APPLICABLE STANDARDS:
UL 1479, Fire Tests of Through-Penetration Firestops. ASTM E-814, Fire
Tests of Through-Penetration Fire Stops. ASTM E-119, Fire Tests of Building
Construction and Materials.
APPLICABLE CODES:
Nelson FSP meets the requirements of all three model building codes
(National Building Code, Uniform Building Code, Standard Building Code),
as well as the National Electrical Code, the Life Safety Code, and most
state and city codes. For specific approval information contact Nelson.
LIMITATIONS:
Although Nelson FSP is compatible with most acid and chemical spills,
heavy exposure or direct contact with strong chemicals is not recommended.

5. INSTALLATION:
Choose the appropriate
firestop system using Nelson application data sheets, the UL Fire Resistance
Directory, Factory Mutual Approval Guide, or other directories of acceptable
designs. No special skills or tools are required. To ensure adequate adhesion,
all surfaces shall be clean and free of dust, grease, oil, loose materials,
rust or other substances. Apply the required depth of Nelson FSP over
various backing materials as required. Make sure the Nelson FSP makes
complete contact with the inside surface of the opening and also the surface
of the penetrating item. The suggested method of installation is hand
packing.
Nelson FSP is available
through authorized distribution worldwide. Contact Nelson for the location
of the nearest distributor who is able to provide cost and availability
