In the event of a fire, LSZH sheaths release far less smoke and non harmful halogen gases when burning compared to non-LSZH wiring. Public buildings such as airports, rail stations, shopping malls and stadiums are common places that LSZH cables can be required to reduce the risk of harm in a fire situation. Low smoke gas density is also a very important part of LSZH cable. Both smoke inhalation and the amount of dark smoke caused by fire that can prevent people from finding escape routes, is a major factor in causalities. LSZH cables are recommended for Green Star rated building projects due to the low toxicity and low smoke design.
