Low smoke zero halogen or low smoke free of halogen (LSZH or LSOH or LS0H or LSFH or OHLS) is a
material classification typically used for cable jacketing in the wire and cable industry. LSZH cable jacketing is
composed of thermoplastic or thermoses compounds that emit limited smoke and no halogen when exposed to
high sources of heat.
Most network cables are insulated with polyethylene, PVC or thermoplastic polyurethane. In a fire, a chlorinecontaining plastic material releases hydrogen chloride, a poisonous gas that forms hydrochloric acid when it
comes in contact with water. Designated halogen-free cables, on the other hand, do not produce a dangerous
gas/acid combination when exposed to flame. However, gases produced by all burning materials�whether
LSZH or not�are extremely toxic.
Low smoke zero halogen cable reduces the amount of toxic and corrosive gas emitted during combustion. This
type of material is typically used in poorly ventilated areas such as aircraft, rail cars or ships. It is also used
extensively in the railroad industry, wherever high voltage or track signal wires must be run into and through
underground tunnel systems. This reduces the chance of toxic gasses accumulating in these areas should the
wires be damaged by fire or a short circuit fault.
