What is a Low Smoke Cable?

A low smoke cable has a LSZH sheath. LSZH stands for Low Smoke Zero Halogen and refers to the compound making up the sheath of a cable. In the event of a fire, this type of sheath will emit very low levels of smoke, and non-toxic levels of poisonous halogen gases (typically under 0.5% HCl emission).
After the King’s Cross fire in London in 1987 it became mandatory to use this type of sheathing on all London Underground cables since the majority of fatalaties occurred through gas and smoke inhalation rather than directly from the fire itself. This type of sheathing is mainly recommended for use in highly populated enclosed public areas.
Other equivalent terms for this type of sheathing are LSHF (Low Smoke Halogen Free), LS0H (Low Smoke Zero Halogen), 0HLS (Zero Halogen Low Smoke).
