Wednesday/ gas pipeline explosion

There was a big gas transmission pipeline explosion in Prince George, BC, Canada, on Tuesday.  Even though it is 500 miles away, it is impacting us here in Seattle as well, since we get some of our natural gas from Canada.

Our local gas utility company is requesting that everyone to turn down their thermostats, and limit the use of hot water and electricity for a day or two. (Natural gas is used for some electricity generation).

Here’s the results of a few online searches I did .. these gas transmission pipelines are typically 36 in (0.92 m) in diameter, and pressurized to 50 times atmospheric pressure.
Interesting map of gas transmission pipelines in the United States. Check out the Gulf of Mexico coastline in Texas & Louisiana – whoah. That’s where all the refineries are, that produce natural gas and other products from crude oil.
