My work was evacuated because of natural gas smell. My truck is near the building. I smell gas real bad around my truck. Ok to start?
 
The odor of natural gas is overpowering well before it approaches the lower limits for fire or explosion. Start it up and drive away. Probably better you do so as the workers may need to access that area if you can smell gas there. Possibly a break in the pipe under the street or parking lot.
 
I'd be surprised they even let you near the parking lot while there's still a leak. I'd wait it out.

The odorants used can be sensed by you in the ppb level. Minuscule amounts. This is by design.

There is a lower and upper flammability limit. Too little and too much will not burn/explode.

Best to have an all clear. If the leak was located and fixed, and dispersed sufficiently from there, anyplace else should be fine.
 
Well it was quite a night. Turns out it wasn't just my building, it was 3 towns. Gas line over pressurization caused 70 fires and explosions. Armageddon is the best way to describe it. I didn't get home for hours because they evacuated 150k people and the highways were slammed. No work today, Gas and power still shut off.

True, better known as UEL and LEL (Upper and lower explosive limits)

Mercaptan is added to both propane and natural gas as both are odorless without this additive.

Without a properly calibrated gaspro or something similar to measure explosive/toxic atmospheres, one cannot simply say they are good to go.

Max, that is some seriously bad information to give out. Many people have been killed or severely burned due to ignorance or the feeling of it can't/won't happen to them.
Google Charlie Morecraft, and others, and see for yourself.

Wouldn't it make sense to discuss with someone like A FIRE MARSHALL....and not some know it all on the web....lol

Very true. If he had of listened to the first reply he received from Max, he very easily could have been severely burned or killed!

We have a saying at work. "If you don't know, don't go" Meaning, if you have any questions or reservations about anything, find out first from someone who knows what they are talking about.

Listening to answers from someone on the internet, is not that someone!

Did you read what happened? The FIRE MARSHALL was busy. The fire department for the entire state was busy. I don't consider this board the random "web". I consider the people on here knowledgeable and honest.
 
shout out to Trav and Jaraxle. You guys handling? I suspected an over pressure. I don't know anything about natural gas pipe lines. But I know enough not to get in the way of remediation personell.
 
So. Lawrence, Andover and North Andover.

I lived in Andover from 1973 - 1986.

My buddy was told to evacuate ( lives behind and south of Phillips Academy)

but he could not figure out what to do with his two big dogs - so he stayed.

I said : open the windows in the basement and the house, shut off the gas and - don't light a candle! and you should be good.

This is the most messed up thing Ive ever seen a public utility do wrong.

Andover had over 35 fire and explosions within an hour and 18 simultaneously.


Accordfing. to my research today, Natural gas regulated domestic ( after the meter) should be under 14 inches-H2O and maybe around 7".

Street can be over 100 psig but is usually less depending on a couple variables.

This local event made primtime national news.

There is a Darwin Awards story about 2 employees of the gas company , that is similar to this .

You all have probably heard it .

Relighting 75k people. What on ordeal. Figure on $8 million plus for each fatality, twice that total for the injuries, very significant property damage, and a system-wide evaluation and replacement of substandard pipes ( and I'm guessing they have miles and miles of corroded pipe). This will probably be a couple of hundred million, anyway.

I've had to deal with a few leaks over the years. I simply called the utility, they sent people out with detectors, found what was wrong, and fixed the issue. Here, at least, anyone can call them if they notice the smell of gas. If it's the SaskEnergy side of things, they do the repair for free. If it's in one's own gas plumbing, they would bill for that.
