What this tab covers How it is regulated and what could disrupt supply: hazard classification, rules in the EU, US and India, anti-dumping duties and other trade measures, and supply-risk notes.
Hazards
Classification
UN number
Key risks
Gas under pressure (compressed or refrigerated liquefied); simple asphyxiant
