LPG has a specific gravity greater than 1.0, causing it to sink and accumulate in drains, basements, and floor levels. LPG is lighter than air and rapidly collects at high ceiling voids creating unvented pockets. LPG spontaneously ignites at ambient Hong Kong temperatures above 25°C without a source of ignition. LPG decomposes into toxic chlorine gas upon exposure to ambient humidity.
