Have a safe weekend. Don't need something like that happening twice in a lifetime. My husband worked in a mill years ago where a lot of fine sawdust was generated. There was a fire by one of the machines and the operator shut the big fans off. This caused the fuel to oxygen ratio to increase which resulted in an explosion. Running a fan while firing the kiln might be an idea so any remaining gas doesn't accumulate. 

As my thinking follows never assume, I went to mayor's office on Wednesday, asking about firing the kiln. Mayor told me to go down to the guys working on the street from the gas company, and ask. Top guy there told me that there was no problem with the gas now at my side of the block evidenced by the road being opened and that their testing showed that the soil was no longer saturated. I explained that I was in a garage in back of the house with the firing and the garage was over the river tunnel. He said all of that had been cleared. Fired the kiln that day. The cone adjustment of -35 is not quite right. Next firing will be with cone adjustment of -30. Getting there.
