Man oh man, I can’t believe what I’m watching on the news, over 50 fires in Lawrence, Andover and North Andover, due to gas pressure issue. Boy that’s going to steer people away from gas heat.

Hope our community is safe and on oil heat, if on Columbia Gas get out or shut gas of.

They must have had to call the entire Boston metro FD. Crazy.

horrible.

I have been reluctant to switch to gas... its like owning a pit bull... no problem most of the time, but only takes one incident

This is mind numbing....

I have always lived in homes with oil. No gas in the street here. As a contractor, my limited knowledge of gas systems practices is that there are PRVs or pressure relief valves, that should open in the face of excess pressure and release into open air, ie. outside, and in commercial buildings, at or above the roof elevation. I wonder if newer designs failed, or if some steps were cut out in the name of saving the almighty buck.....


Fires and explosions that could not even be responded to.... Logistical nightmare. Kudos to all the responders converging through mutual support system and beyond. Sixty plus incidents and counting.

This has been nuts.

Hope the SCADA systems were not effed with /tinfoilhat

Awful what had happened for sure
Unbelievable that nobody was killed yet.
10 people hurt in explosions

Gas company has not even communicated with the fire chief WTF

Something or someone messed up badly here

Makes me think about how vulnerable our power grid and utilities might be. Could a hacker....???

I think chances are around 1 percent but hackers have been targeting Gas Companies / Elec Grid / Utilities, etc. RUS/CHN/IRN/Norks grinding away at SCADA systems.

18 year old, chimney fell on him and his friends while they were driving down the road. 2 other kids that were in the car are still in the hospital.

About one percent chance members know SCADA acronym.... nerd:hs:

classic corporate America money to profits Screw the infrastructure and preventive maintenance.. had a house blow up some years ago in our Town people reported gas smell for years . guess what got replaced soon after the accident ... yep all the gas line in that area

Locally tried to increase pressure to fill demand and created problems...
Sooooo,,, we have every major street in the mid cape area tore up, like we don’t have enough traffic problems...

I sure feel for those folks, where do ya begin to deal with your house blowing up,,, GB

“ National Grid’s plan to replace its main gas line on the Mid-Cape and Lower Cape is on the fast track, according to a company official who said Wednesday that the target date to wrap up the $50 million project has been moved up to mid-2019.
A moratorium on new hookups and expansions of existing service, in effect since October 2014, will then end, Ross Turrini, senior vice-president of gas engineering and process for National Grid, said.
“We’re looking to lift the moratorium April 1, 2019,” Turrini said during a meeting with the Cape Cod Times editorial board.

It's Geek. Difference. SCADA is the backbone systems that control the valves, pumps that make process stuff, process. :bshake:

Go bang a nail.

Yep ! Government should just run everything what could go wrong, yahhh ; )

so i get why, at sufficient pressure the gas would cause the container to explode. by why does it ignite? the pressure causes ignition? it doesn’t require a spark?

The house I used to live next to blew up years ago while a bunch of Stonehill students were inside. Gas company yanked the line while digging and that was enough to create a spark.

Anything, static, spark, water heater pilot light

So it's not the instant release of gas, by itself, that causes the explosion, it's that the high volume of gas will find the necessary spark in many cases...gotcha...

Godawful situation.

Sad situation. I think they shut all the electrical off to try to prevent some of the fires. Read plumbers were running yard to yard to try to shut off the gas.

Yes. When out in the open air it is usually not dense enough to cause the spark, indoors however....

Reminder to take a look outside and familiarize how to turn off gas

1/3 of our work force lives in lawrence..the shop is very quiet today...

Happened right around dinner time, people probably getting read to cook.

A big challenge the utilities have is that they don't have the experience with areas like configuration management to comply with increasing regs for cyber security...so they're bench marking industries like aerospace to learn. A big area of liability still isn't even hacking it's malicious activity within the firewall.

Supposedly it was one of the subs that National Grid also uses, they over pressurised a line. Looks like they will be paying out huge on this

Hacking in the generic term.

Don't want to get hacked? Stay off the effing Internet.

I meant they're almost more vulnerable from inside attacks, nefarious employees with thumb drives etc...

I am by far an expert on any of this but is it comparable to higher compression equals higher combustion like in a diesel engine? Either way scary and sad....I'll stick to electric...... praying for all involved.
