Why is LSZH (Low Smoke Zero Halogen) mandatory for fire-rated installations?

In the international market, particularly for public infrastructure and high-rise buildings, PVC is often restricted.

Safety: LSZH materials do not release corrosive “Acid Gas” (Hydrogen Chloride) when burned. This protects sensitive electronic equipment from corrosion and, more importantly, ensures that smoke is thin and non-toxic, allowing for clear visibility during emergency evacuations.
