>can I and my family survive by wearing gas masks for 7 days? Methane isn't poisonous, the only way it can kill you is by displacing oxygen. Gas masks can't filter it, you would need an oxygen mask. Sheltering in place is slightly more practical: sealing doors and windows, using CO2 sorbents to absorb CO2, and oxygen canisters to replace consumed oxygen. Would be pretty expensive-- I wouldn't bother unless you lived next to Lake Nyos: https://en.wikipedia.org/wiki/Lake_Nyos_disaster https://en.wikipedia.org/wiki/Lake_Nyos_disaster
