1.4.2.14 Pillow (also referred to as “bag” or “cushion”)

Malleable, pillow-like bag, filled with reactive or non-reactive material, for the temporary or permanent closing of penetrations or openings.

1.4.2.15 Pipe closure device

A pre-fabricated, heat activated device that, under fire exposure, acts to crush plastic pipes or service ducts that pass through vertical or horizontal separating elements and/or fill the hollow space with an intumescent foam. Two types are considered here: collars and wraps.

Collars incorporate an outer casing which acts as a restraint for an intumescent material, enabling the collar to be either surface fixed to the separating element or incorporated within it.

Wraps have no casing and hence must be located within the separating element, which acts as a restraint for the intumescent.
