The TEMPOFIX 3 frame system © DELABIE
Firstly, a fire-retardant frame can delay the spread of flames by up to 60 minutes. British Standard BS EN 13501-2 identifies three aspects of fire-resistance: ‘E’ indicating integrity and the ability to withstand flame and smoke to prevent their spread; ‘I’ for insulation, which prevents the transmission of heat; and ‘W’ which indicates the ability to restrict the spread of radiation and toxic gases. So, for example, a frame system with a rating of EI 60 will withstand smoke and flames as well as insulate against the transmission of heat for 60 minutes. The second super power of a fire- retardant WC assembly derives from its valve housing which has an intumescent collar. The collar on the housing has inherent characteristics which allow it to swell when exposed to heat, increasing its volume and decreasing its density. It provides passive fire protection, sealing any apertures in the housing to prevent the passage of oxygen which is vital for fuelling the fire. In effect, there is no need for human intervention in a dangerous environment, closing off the fire’s access to oxygen without the need for a fire extinguisher.
The third life-saving aspect of this HBD HP Advert_Golden QP 19/06/2017 16:27 Page 1
unassuming toilet frame is its soil pipe and connector which are also made from intumescent substances. Again, their ability to expand ensures that flames, smoke and noxious gases cannot pass from one room to another. In situations where the spread of smoke can pose as much of a threat to life as the actual flames, the ability to slow and prevent its spread can also be vital to preserving life.
Unlikely hero Until recently, safer washrooms meant preventing scalding from hot water, or improving hygiene to prevent the spread of germs and bacteria. In this new post- Grenfell era, it also means tackling the risks posed by fire and smoke.
Not all the solutions are immediately obvious, but the humble toilet frame system is a surprising one. By putting fire safety on the agenda during washroom design it is possible to provide washrooms that are safe for the user. A fire-retardant frame system can really make a difference when vital seconds count.
