Is ethylene gas flammable?
Yes ethylene is flammable. Natural gas, which is most likely piped right into your house is also flammable and about the same level of danger as is ethylene. Were you to have a gas leak in your house an explosion is very likely and such an explosion would cause substantial injury or death. The ethylene plant is subject to rigorous safety procedures and is not likely to explode. But if it did, it is pretty hard to estimate the degree of damage and injury.
