Carbon tetrachloride became very rare from being phased out internationally after 1989, but some relics of the past still contain this oncewidely used chemical. Its toxicity didn't help its popularity after the 60s/70s, so its been practically 100% replaced by alternatives. In some countries carbon tet isn't that rare still! But in a country like Aus, where you basically can't import it, and we do not manufacture it here, over the last 3 decades its been completely phased out. Twitter:   / explosions_fire
