The Passive Fire Protection Handbook Chapter 7: Penetration Seals IMPORTANT NOTE: Because of the diversity of applications and the on-going test programmes, the following notes on this section are of a general nature only and it is essential to confirm that the system specified or being installed is approved for use. Please contact the Promat Technical Services Department to confirm correct specification. FLOORS, SLABS OR WALLS In every application discussed in this handbook, irrespective of whether it is using a Promat product or system, the importance of sealing any gaps in fire resisting...

The Passive Fire Protection Handbook Chapter 7: Penetration Seals Failure Criteria Failure is measured in terms of integrity and insulation. Stability (or structural adequacy) is not recorded for service penetrations. Integrity failure occurs when cracks, holes or openings occur through which flames or hot gases can pass. This is measured in different ways, depending upon the standard used. a) Using a cotton pad, held against any gap, to see if the cotton pad ignites within 10 seconds; or b) If the gap is equal to or greater than 150mm x 6mm; or c) If a 25mm diameter probe can pass through...

The Passive Fire Protection Handbook Chapter 7: Penetration Seals – Fire Collars FIRE COLLARS FOR PLASTIC PIPE PENETRATION It has been shown that plastic pipes penetrating compartment walls or floors or other fire barriers present the potential for fire to pass from one compartment to another when the plastic melts and burns away. All Building Regulations specify that the fire rating of the separating building element between compartments must not be impaired by services that pass through them. The acceptable methods of maintaining this fire rating will vary, however by far the most...
