6491B / H07Z R Low Smoke Zero Halogen Power Cable Heat Resistant Wire
The "Low Smoke" element of LSZH cables
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."
Burning PVC has been found in tests to reduce visibility in the
surrounding area by as much as 50% within 10 minutes. After 30
minutes, visibility can be reduced by as 90% making it
unnecessarily challenging to escape the area.
