The London Skyline is a topic of great concern, especially relating to the possibility of Fire in a high-rise building. As buildings get taller the consequential risk of fire increases with every additional floor. Fire fighting, externally, is limited and gridlock streets makes the task even more hazardous. It must be born in mind that 40% of the fires globally are the result of electric cable malfunction. Accordingly, fire management and modern predictable communication systems, have to be absolutely fit for purpose but are the cable systems employed likely to perform, as one would expect, in real fire conditions? That is the question.
The common understanding amongst most specifiers, sellers, installers and users of electrical cables, which are manufactured to meet the requirements of common fire Performance tests like: Flame retardance tests: Smoke obscuration tests, Halogen and acid gas emission tests, is that the cables they subsequently specify, buy and use will provide a similar performance under real fire scenarios that the test methods suggest. Unless the cables are exposed exactly to the same conditions, as documented in the test, which is unlikely, this is not likely to be the case and with disturbing consequences.
Three technical documents are available, on request, from the author, Richard Hosier, relating to “Electric Cables Fire Performance”, which may be of interest to AJ readers on the performance of electric cables in real fire conditions. (Flame Propagation, Fire Load, and Life Span). We would be pleased to discuss and modify the articles, which we believe should have greater publicity. The Great Fire of London is a chapter in the great City's history, lets all hope that our buildings are suitably equipped to deal with a major fire should the situation ever arise in the future A big ask - I'm afraid?
