While cyclopentane is not typically used as a refrigerant, it is common for domestic appliances that are insulated with cyclopentane-based foam, such as refrigerators and freezers, to be marked with cyclopentane warning labels due to its flammability.
Not sure about the rate of diffusion through the foam. My intuition is that it would be replaced with air in a matter of months, but that’s purely a guess and depends on the composition of the foam.
I feel confident predicting (but am willing to argue!) that they are not gas explosions caused by ignited pockets of natural gas, propane, gasoline, insulation outgassing, butane, etc.
That leaves likely fireworks, firearms, possibly dust or lint.
You could well be right. This was something I just happened to notice while I was cooling my heels in a gift shop while my wife pored over trinkets and tchotchkes (sound familiar)?
Sorry, this is quite off topic from the OP question… I don’t have any good hypotheses about that…
Somewhere in my apartment, if the lousy movers didn’t toss that too, should be a small metal sarcophagus containing flash paper. I also have a small plastic cannister filled with flash powder. I am not sure where they are. But, I know they are not in my kitchen.
I wouldn’t replace the stove without calling an appliance repair shop.
Gas ovens are pretty simple. It’s probably a bad gas valve. Each burner should have a valve. The oven has a separate valve.
Modern appliances have electronic controls. But a bad part can be replaced.
You need a plumber to do a leak test. They pressurize the gas pipes and install a gauge. It has to hold that pressure for a certain amount of time. Then the gas company will turn the meter back on.
I am not replacing the stove. At some point soon, I hope to have decluttered enough to safely have maintenance in my apartment. They will replace the stove. I will not be paying for a new stove or providing any of the labor.
Back To The OP
I want chocolate badly. Normally, I would just walk a few blocks to my favorite of the mini marts and buy some. At presnt, I am terrified that once I leave home there will be another whatever the hell that was. The smoke detector seems to be working. I am confident that no tenants will be harmed and no structural damage will be done. However, loss of my stuff is my second greatest fear. Loss of a loved one is my first. My death or dismemberment are a distant third.
The gas to the stove has been turned off since around the time I started living here. The three radiators providing heat are apparently electric. Plus, the gas company sent out two workers today. They could not find a gas leak.
I can’t speak to specific equipment used by PGW or PFD but the two departments could have had the exact same meter or PFD could have had one that will ‘sniff’ for even more things than PGW’s since they are concerned with more things than just natural gas.
Although they are calibrated & do self-checks when turned on a meter could break; however, the chance of two meters, from two different agencies not picking up gas means there’s no gas there.
This!
There are not emergency cops & non-emergency cops, there are just cops. They respond to calls in (ranked) order; obviously a shooting takes place over a barking dog but a barking dog vs a parking complaint should be handled in the order they were received. PSAPs (911 call centers) realize this & anymore, whether you call a 10-digit local # or 911 you’re going to be talking to the exact same person; they’ll get all your who, what, where info, enter it into the computer, code it & hand it off to dispatch.
The same is true with the FD, there is only one FD & they respond to all calls ASAP. Yes, a lot of the “smells & bells” (odors & alarms) are BS but the FD should respond to each one as if it were real because some of them are.
I know that Philly doesn’t even have a non-emergency # anymore; you have a dog complaint or an illegally parked car, dial 911. It saves them a little on having a second phone line.
I am reasonably sure that the smoke allarm in my apartment detects carbon monoxide. I know the one in the apartment next door does. Her kids set it off by forgetting to take the pots and pans out of their stove before pre heating it.
If you have natural gas piped into your living quarters and appliances, that is just about the only possible source of these little explosions, a gas leak. May just normally dissapate and cannot be smelt by you or the inspectors until it finds a spark. Whoever checked and said it was not a leak is either incompetant or ignoring a problem. They need to look again, and replace that damn oven. .
Little explosions do don’t just happen without a cause, but what they DO cause is bigger explosions. Do not back down and look for other causes, it’s the gas and somebody does not want to address it. This is kind of one of those “may cause death” things, for you and other residents in the building. Replace the damn oven.
Either that or Ball Lightning. Which do you think is most likely?
I realize you don’t want to spend the money, but it might be worth your peace of mind to bring in a plumber to disconnect the stove completely and cap off the gas lines. Plumbers are very experienced at this sort of thing, and I would generally trust one to get this right, without allowing any leakage at all at the gas line caps. You could leave the stove in place until you are ready to have maintenance come in and replace it.
Not that I’m agreeing that the gas company inspectors and the fire department are all slackers who are too lazy to find a gas leak. But I can imagine a transient leak that just happened to not be active when they were there. If that’s what is going on, it may not be dangerous now, but it could grow and become so.
I have no qualifications in this area beyond being a homeowner who has a gas stove and other gas appliances.
