Toxic substances list: sulphur hexafluoride - Canada.ca

Toxic substances list: sulphur hexafluoride. Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.Get price
