me, an hour ago: "fuck, the stove is on! what do we do?" [immediately does all the wrong things]
PSA: What NOT to do when you smell gas
In this situation, we got home to a smell of gas throughout the house and discovered our gas stove was on without a flame. it was only a tiny stream, and everything turned out fine, but here's a brief list of everything we did wrong:
NOTE: this is for if you smell significant amounts of gas, not a blanket list for all possible gas situations. (If you aren't aware, the methane**/natural gas used in houses smells vaguely like sulfer, or rotten eggs - this is an additive, since it has no natural smell. It's a very recognizable smell, once you've smelled it once. It's not the same smell as gasoline.)
1. If your stove has an electrical/spark ignition, do NOT turn it off.
Spark ignitions often spark when turning on *and* off. Spark + Gas = Boom. Boom is bad. Avoid boom.
Instead, turn off the gas at the source, i.e. the physical valve at the meter. There may be a smaller valve near the stove. If you don't know where the shutoff is, the fire department will find it.
2. Do NOT turn on (or off) vents or fans.
In fact, don't flip any electrical switches - that includes lights, plugging in or unplugging appliances, etc. These cause sparks. Spark + Gas = Boom.
Also, don't start your car. obviously.
3. Do NOT open windows
counterintuitive, I know. This is mostly because you want to prioritize your exit, but it's also to keep the fumes from spreading outside, where you should be waiting for the ~professionals~ to come handle it.
4. DO take all people and pets outside.
Do this very first!! (one thing we actually did right - go us!)
This is obviously because you don't want to go boom, but you also don't want to suffocate. Gas is poison!
NOTE: the gas from your stove is probably methane (natural gas); carbon monoxide is what you get when methane burns, which is why your kitchen needs to be well-ventilated and the stove shouldn't be left burning for long periods of time, but the natural gas itself is *also* potentially deadly. Carbon monoxide detectors dont detect natural gas, so that's what the odorous additive is for.
Inhaling natural gas causes nausea, headaches, dizziness, and makes you just generally woozy, and eventually causes you to lose consciousness and potentially suffocate, just like carbon monoxide does. We don't want that.
5. DO call the fire department/emergency line
They'll check for other leaks, shut gas off if needed, then test for air quality and eventually clear your house for reentry. It takes like 1-2 hours for the gas to dissipate, generally.
Yay, you survived! Congrats!!
NOTE: if you find the stove has been left on with a flame, or it's on with no flame but you don't smell gas, then you should be safe to just open windows and turn on vents and fans to air it out.
idk, this was actually pretty scary, especially when we realized how much of our immediate response was wrong and could have turned a dangerous situation into a real disaster.
tl;dr: If you smell gas when you shouldn't be smelling gas, just get all the people and animals outside, shut off the gas line, and call the fire department or gas company. don't fuck around with gas. you're not overreacting, you're taking the proper safety measures.
**CORRECTED FROM ORIGINAL VERSION. Original said propane, but it's very much not propane, it's methane. too much Hank Hill on the brain, clearly.
