There's an inevitability to this one that's almost comforting:

Yep. Entirely predictable.

Not a good time to own stock in Columbia Gas of Massachusetts.
When your workers fuck up doing a gas line replacement and blow up 40 houses, displace 8,000 people, and kill one person, you're doing something wrong. Can you imagine? They must have turned off the gas, all the pilot lights in town went out, and then they turned it back on again. The gas flowed through all those appliances with no pilot lights to ignite it, and then the houses blew up when the concentrations got high enough. I wonder if hackers can hack the municipal gas valves remotely and do a terrorist attack that way? Makes me wonder exactly how gas appliances work. Do modern ones only open the gas valves when certain ignition temperatures are confirmed? I know my oven works that way, but my 70 year old furnace doesn't. How about water heaters? Is there some sort of pilot light confirmation system? |

Starting a pilot light meant holding a button for maybe 30 seconds while lighting the pilot. So that the thermocouple got hot enough to not cut off gas. That was standard even in 1950. Part that failed most often was that thermocouple. Appliances, since the 1980s, no longer use a pilot flame. If electricity does not ignite gas, then gas is cut off. |

 And! There is a cute little wolf spider down there that's hunting camel crickets. I tried to capture the reflection of his eyes, but it didn't come out so well. You can see it a little bit.

The news just mentioned in between flooding news that there are 60 fires in Boston.

My wall furnace uses a pilot light. It's a sight newer than 1980.

If the pilot light goes out doesn't it shut off the gas supply?

We were talking about his wall heater.

It does in my house. There is some kind of thermal cutoff that cuts the gas if it cools. The pilot keeps it warm enough to keep the gas flowing.

Now to understand the problem and what will be relevant in press reports. A gas system distributes gas at high pressures. At multiple points, regulators repeatedly reduce pressure until gas into a house is maybe 3 PSI. Apparently a high pressure surge started in Ohio. Then travels across three states. Somehow this pressure wave may have blown through layers of regulators.
Also are many pressure relief valves including one maybe at each consumer's gas meter. How did all this fail? A resulting investigation should be informative. |
