Design
A : Concrete Floor of minimum 200 mm thickness
B : Cable tray or bundles
C : Foam
D : Ceramic Slab of 25 mm
E : Control panel ( Obstructing top exposure )
F : Hole through liquid poured.
Compliance
UL 1479 2hr. F & T rating FM approved ASTM E662
Expanding Foam
Made from two component liquids, A & B. On mixing in ratio, the mixed liquid expands volumetrically, filling gaps/ voids between cable bunch and spread to fills opening of any size or shape. Within 3 minutes, it forms a medium density foam which is fire retardant. Require shuttering plate of ceramic wool slab and plugging with wool for prevent leaking, which may be left as it is fire resistant.
