Safety description 
S9; S16; S33

Methane is basically non-toxic to humans, but when the concentration is too high, it can significantly reduce the oxygen content in the air and cause asphyxiation. When the methane in the air reaches 25%-30%, it can cause headache, dizziness, weakness, inattention, accelerated breathing and heartbeat, and ataxia. If not kept away in time, it can lead to death by asphyxiation. Skin contact with liquefied methane can cause frostbite.

Hazardous characteristics: flammable, mixed with air can form explosive mixtures, and there is a risk of combustion and explosion when encountering heat sources and open flames. Reacts violently with bromine pentafluoride, chlorine gas, hypochlorous acid, nitrogen trifluoride, liquid oxygen, oxygen difluoride and other strong oxidizing agents.
