avt sf6 o2 evacuation

Apr 12, 2021 · Pure SF6 is physiologically completely harmless for humans and animals. It's even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Legislation for chemicals does not categorise SF6 as a hazardous material.
