All the locals freaking out over the supposed radiation death cloud wafting in from Japan are encouraged to remember that in Washington we have our own different sort of nuclear catastrophe called the Hanford Site. And while the hydrogen "puff" it apparently farted out unexpectedly yesterday is said to not be dangerous, it's a good reminder that the site is still there.
The hydrogen "puff" incident happened when some workers were cutting into a pipe, reports the AP.
Apparently the workers thought that the gas in the pipe had been purged--obviously it hadn't. A flame ignited out of the pipe when they cut in, and an unknown number of workers were evacuated.
Again, nothing to panic over, but it never hurts to remember that Hanford is the largest nuclear-waste dump in the Western Hemisphere.
