This Listing is based upon the hydrocarbon fire time-temperature curve conditions required by the
International Maritime Organization (IMO). The Norwegian Petroleum Directorate (NPD) also defines
this exposure.
1.
HOLLOW RECTANGULAR STRUCTURAL STEEL COLUMN:
Use hollow steel sections,
rectangular shape, having nominal Hp/A, W/D, or A/P section factors based on four sided exposure.
Refer to Table CC/CA 180-03 for specific application thickness of intumescent mastic fireproofing
(Item 2B) based on nominal Hp/A or W/D section factors.
2.
FIRE-RESISTIVE COATING:
Refer to Table CC/CA 180-03 for specific application thickness of
fire resistive coating.
A.
Intumescent Fireproofing:
Spray or paint in one or more coats according to manufacturer’s
instructions to a nominal 1/2 the required thickness or 3mm) (0.12”) (whichever is smaller) before
applying high temperature fabric (Item 2B). Spray or paint in one or more coats according to
manufacture’s instructions to required final thickness after installing the high temperature fabric
(Item 2B).
CERTIFIED PRODUCT:
Fire Resistive Coating. MODEL: Thermo-Lag 3000
B.
High Temperature Fabric:
For final thickness of the intumescent fireproofing (Item 2A) of 6mm
(0.24”) or less install high temperature fabric at middle depth of the intumescent fireproofing (Item
2A) (±1 mm). For final thickness of the intumescent fireproofing (Item 2A) greater than 6mm
(0.24”), install high temperature fabric at 3 mm (0.12”) from solid structural steel column (Item 1)
(±1 mm). Wrap high temperature fabric completely around hollow rectangular steel structural column
(Item 1). Overlap high temperature fabric a minimum 26mm (1”) at seams.
