What does LSOH (Low Smoke Halogen Free) mean?
VueNet LSOH is internal Cat5 cable, which because of its thermoplastic construction emits limited smoke and no halogen when exposed to high sources of heat such as fire.
What regulations are there?
According to Part B of The Building Regulations, a leading planning and building regulations resource for England and Wales:
"The primary danger associated with fire in its early stages is not flame but the smoke and noxious gases produced by the fire. They cause most of the casualties and may also obscure the way to escape routes and exits. Measures designed to provide safe means of escape must, therefore, provide appropriate arrangements to limit the rapid spread of smoke and fumes."
