FRLS stands for Flame Retardant Low Smoke, are fire resistant cables which are used at the locations which are more prone to fire.
Flame Retardant Low Smoke PVC compound which is present in the cable, ensures low smoke release compared to other wires with PVC coating. They are less toxic in nature and emit low amount of corrosive fumes.
FRLS cables should be used in places with major possibilities of fire accidents namely : power plants, industrial complexes, hotels and places of public gathering. Hence the cables used in the various electrical installation must be resistant to fire and yet be functional and not increase it.
When implementing FRLS cables, panic factor is reduced hence making the evaluation of buildings easier. This enables aiding damage control operations preserving life and property.
