If so, it sounds like someone forgot to call their municipality to find out the location of the cables before they dug.

Look at it this way- they just hit the phone cables. Could have been worse.

-glances down at the "Warning: underground Hydrogen Pipeline" signs at school-

Oh no, it will release hydrogen and water will form! Not that! Hydrogen is nowhere near as dangerous as people make it out to be. The Hindenburg and other dirigibles created a very bad impression in the public's eye about hydrogen power...

Last time I heard, hydrogen in a confined space with oxygen is extremely explosive.

And you do get water or rather water vapour:

2H2 + O2 = 2H2O

if I remember my chemistry of many years ago.

Close... It was the Hindenburg. Lindenburg (or was it just Lindburg) was the name of a pilot who's child was kidnapped.

Or so my garbled history recalls...

Yeh, I think you are right, it was the Hindenburg.

I think the reason the Hindenburg did not explode was because it was not in a confined space and oxygen was not mixed with the hydrogen.

As the hydrogen and the oxygen were separated, the burning essentially took place on the periphery and moved inwards as the oxygen moved inwards.

Also air is only about 20% (21%?) oxygen, it is diluted and the rate of burning is much reduced than if it was pure oxygen.
