Michael Huwar, president of Peoples Gas, said the company's checks for gas leaks underground and in the air as well as the consistent pressure verified at regulation stations indicates that "our system was operating as designed."
would have been a big leak to do that, so you have to believe them
"slow and long process" that would include a lot of forensic testing and could last "months if not years."
I mean. This line strikes me as a bit odd. It seems like natural gas explosions are common enough to be self-evident, which means it shouldn't take years to do an investigation. Also, the size of the fireball, that really seems like a natural gas explosion. And if its not a natural gas explosion, what then? For example, this explosion in Pendleton was the result of home made fireworks.
yeah it's obviously amateur chemistry of some kind, might as well start with that.. a large volume of some kind of flammable gas was being produced in the basement..
That shouldn't terrify you, with proper maintenance and half a brain you should be fine.
THIS SHOULD TERRIFY YOU INSTEAD: nitrogen oxides (NOx), including nitrogen oxide (NO) and nitrogen dioxide (NO2), carbon monoxide (CO), and formaldehyde (CH2O or HCHO), and unburned gas containing benzene aren't anything you want to raise kids around.
