The Case For Low Smoke Zero Halogen Cable Labels & Public Safety

Today’s world of modern, intelligent and complex buildings demand the highest safety performance from their electrical cables and cable accessories.

Traditional BS5467 low voltage power cable is constructed with PVC sheathing - in the event of a fire PVC cables release toxic smoke and gasses posing safety threats to people and plant.

To enhance public safety a Low Smoke Zero Halogen (LSOH) power cable was developed for installation in highly populated enclosed public areas. This low voltage power cable is a LSOH version of the established BS5467. The cable was given a specific British Standard category - BS6724.

Installing BS6724 Low Smoke Zero Halogen (LSOH) power cable is an investment in public safety - therefore why compromise that safety by then installing sub-standard cable accessories, such as Silver Fox cable labels?

BS6724 power cable is extensively specified for low voltage power distribution to electrical construction and building projects in the UK - especially in public areas where fire, smoke emissions and toxic fumes could potentially threaten both lives and equipment.

Typical BS6724 cable applications include hospitals, museums, retail, offices, airports, rail stations, sports stadium, tunnels, shopping centres and commercial developments.

When exposed to fire, BS6724 Low Smoke Zero Halogen cable sheathing emits very low levels of smoke and non-toxic levels of halogen gas (typically under 0.5% HCl emission).

Silver Fox "Fox-Flo" cable labels are safe and provide protection against all aspects of fire hazard including smoke and gas emissions, flame spread and heat release.


Why Use Low Smoke Zero Halogen Cable Markers?

Safe, risk free cables should not beSilver Fox - Fox Flo Cable Labels compromised by sub-standard cable accessories, such as cable labels, which could emit life-threatening levels of toxic smoke and gasses in the event of a fire.

In fire situations, PVC based cables and cable markers can be a vehicle for flame propagation whilst also generating smoke, corrosive and toxic fumes. Effectively fuelling the fire.

Where consultants and contractors are installing low smoke, zero halogen and flame retardant power cables for low voltage distribution indoors, outdoors, buried or in air, careful attention should be made to specifying equal-specification cable accessories to preserve LSOH circuit integrity.

Zero Halogen Cable Labels

For instance Silver Fox "Fox-Flo" Low Smoke Zero Halogen cable labels are the perfect cable marking system for Prysmian Afumex Low Smoke Zero Halogen cables. Prysmian Afumex is the market leading Low Smoke Zero Halogen Cable.

Other LSOH Cable Applications for Silver Fox Cable Labels : 6491B Single Core Conduit Cables, 6242B Twin Flat Wiring Cables, Screened Wiring Cables and LSOH building cables for power, lighting and sub mains distribution.


Silver Fox Cable Labels - Relationship With Fire

  • Low Smoke Emission - traditional PVC and plastic cable markers release thick black smoke which obscures escape routes and causes asphyxiation, reducing the public's ability to respond in an emergency which can result in mass panic.


  • Low Corrosive Gas Emission - although often invisible, when burnt, PVC emits acidic gas which causes corrosion and failure of electronic equipment. Toxic gasses incapacitate the public trying to escape the burning building.


  • Reduced Flame Propagation - when exposed to flame cables and labels should self extinguish when the flame source is removed.
