u/lazespud2 · 368 pointsr/legaladvice

given that an actual human just died from carbon monoxide poisoning, and that you can buy a detecter for pocket change, I would think it might be a good idea to get one regardless.

Ordinarily I might say "the likelihood of a carbon monoxide leak in someone's random house is pretty minor." But this is a house WHERE SOMEONE JUST DIED FROM CARBON MONOXIDE. Even if you are fairly certain of the source (the generator) it doesn't mean spending 13 whole dollars on a detector is a dumb idea.

u/Jondayz · 210 pointsr/LifeProTips

This one is on sale on Amazon right now for 63% off, $20. It has a digital read out and good reviews. I just bought one. I know you have Prime, order it you lazy ass.

u/politebadgrammarguy · 53 pointsr/RBI

OP listen to the comment you replied to. This does sound like it COULD be Carbon Monoxide poisoning, and that can be very dangerous. Please get a tester and make sure.

You said it only started when you moved, this is what worries me. Could have been a leak in the room from the first day.

Here's two models from amazon that are under $25 if you need a link

u/EmAreDubs · 43 pointsr/Columbus

Yikes. Always make sure your hot water heater and furnace are properly vented to outside, and remember that a $25 device can save your life. For maximum peace of mind, place a carbon monoxide detector in the main living area and in each bedroom.

u/StarOriole · 18 pointsr/legaladvice

Iowa state law already requires that apartments have smoke detectors, so another convenient option is a 10-year-battery CO detector. I upgraded the one in my bedroom to that after I learned how hard it was to count beeps in the middle of the night when 3 beeps = replace the detector and 4 beeps = evacuate the house.

I got about 60 of the 1 lb canisters and 2 of the 20 lb tanks in one of these deck boxes:

http://www.homedepot.com/p/Rubbermaid-73-gal-Medium-Deck-Box-with-Seat-FG5F2100OLVSS/202523344

The two 20 lbs go in a corner each, and then the 1 lbs are arranged around them on the floor. Then I cut a piece of plywood in the shape of the inside of the deck box, with cutouts for the two 20 lb tanks, to make a second story which is laid on top of the first layer of 1 lb canisters. Then I get a second layer of the 1 lbs in there, and it's about 60 of those plus 2 x 20 lbs, makes approx 100 lbs total, give or take. It's been a couple of years now, and they seem to last very well in there. I also keep some adaptors and hoses so I can hook the 20 lbs up to the Little Buddy heaters and the propane stove etc. I keep the deck box on the lower deck behind the house in a spot under the upper deck so that it doesn't get a lot of direct sunlight. I think it's probably better if it doesn't get too hot. Also, if anything leaks, then propane is heavier than air, so you want the path to be away from the house, not down into your crawlspace or basement. Finally I recently got a "WARNING PROPANE" sticker (from Amazon) for the firemen should there ever be a fire around my house. They should know about that amount of propane, for obvious reasons.

One last thing: Consider getting a couple of battery powered carbon monoxide detectors, just for peace of mind, e.g.

u/MisterQuimper · 9 pointsr/LifeProTips

Gonna risk the /hailcorporate tag but now is a good a time as any to stock up on CO detectors. MA code mandates at least one for every floor in your house (seems a bit overkill since CO doesn't rise) but one near your furnace is a bare minimum

That is the one I have in my car and my house.

I got one after a father and son in my city died while waiting for their car to warm up. They didn't know they had a leak in their exhaust and the CO doesn't smell like exhaust. It has no smell.

u/DrTom · 7 pointsr/vandwellers

You want a Mr Heater Buddy, man. Easy to use, safe, cheap to run, and it will keep you warm in a space much bigger than a van. Highly recommended.

EDIT: for safety, make sure you install a carbon monoxide detector.

u/TheBruceDickenson · 5 pointsr/OffGrid

If you don't have the wood yet you might be in a pinch. I burn wood to heat our house all winter, but definitely not anywhere near -30c. How much wood depends on the type of wood. Each species has a different BTU rating. Some burn hot and fast others are low and slow. I tend to use both. I like Poplar to get the stove warm and Oak to bank it all night.

​

I cut my own wood but if you don't you will need to be careful of sellers saying it is seasoned. A true seasoned piece of wood will be cut and split (generally) for a year. Some sellers will cut and split in the late spring/early summer and try to sell it in the winter. That won't cut it for most guys burning wood. I highly suggest investing into an inexpensive moisture meter. Split a piece of any wood that you are buying and test it. I try to burn at 20% or less.



Also, it might be really helpful for you to get a wall mounted propane heater. They are inexpensive (under $150 at the local big box store or on Amazon). Keep it on a thermostat to kick on if the wood fire goes out. Really helpful on punishing days. If you get the smaller 100 lb tanks you can take them to the filling station and have them filled cheaper than delivery.


Oh and get a carbon monoxide detector. If need to make sure you have enough fresh air in your house to support your wood burning stove and your ability to breathe!

u/pyjamatoast · 5 pointsr/NoStupidQuestions

You should have one detector for each floor that has people sleeping there. They're $20 on Amazon, just buy a couple more and you'll be set.

u/brewerdoc · 4 pointsr/Homebrewing

Carbon monoxide can be produced by any fire. If you are heating anything by "gas" in your house be it propane, butane or whatever, you should have a carbon monoxide monitor. You can find them for about $20-30 dollars. amazon link to a CO detector.

Symptoms of carbon monoxide poisoning include:
-Dull headache
-Weakness
-Dizziness
-Nausea
-Vomiting
-Shortness of breath
-Confusion
-Blurred vision
-Loss of consciousness

I admit a couple of people to the hospital a year who get carbon monoxide poisoning. It's never pretty and the treatment is limited. Hyperbaric oxygen is one of the treatments but many hospitals do not have this option so they resort to putting a mask on the person who inhaled the poison till they can call other hospitals till they find one that has the hyperbaric oxygen treatment.

Even if you have a "gas" furnace, water heater, stove or brewery in your house you should have one of these. The molecule has no smell and by the time you notice the effects its usually either too late and its very advanced.

At the 2100ppm level the fire department measured an adult has over an hour to get out to clean air, a child has less, but that alarm would have certainly given a heads up, especially if you hear all of your neighbours having them go off in the hallway at the same time.

u/Trey5169 · 3 pointsr/GlitchInTheMatrix

This is just a few seconds of searching from a random internet stranger, but look for a few of these at your local wal-mart. Also, I always thought that CO was heavier than air, but apparently it is slightly lighter than air. This suggests that CO detectors should be placed rather high, on the ceiling if possible. If you're in doubt, just place one as high as possible - if you get a reading, use an extension cord as a temporary way of measuring the levels in different locations, high or low. (I'm not sure how quickly the sensors update, you may need to rig a way to hold the sensor in place for a few minutes, try these things.)

Best of luck to you and your friend! (Maybe get a detector for her as well... though it sounds like you're more affected than she is.)

Also, keep an eye out for /u/RBradbury1920, he left post-it notes for himself, it turned out to be a side effect of Carbon Monoxide poisoning. (Only 100 PPM, apparently.)

Edit: How close do you and your friend live? There might be something in the environment doing this to both of you, such as a gas leak or something. But if so, then other people might be noticing strange things as well....

u/Jessie_James · 3 pointsr/homeowners

Can you open all the windows for a few days and see if that makes a difference?

Do you have gas appliances? If so, consider purchasing a low level CO detector like this one.

We had a scare a few years ago when the gas furnace had a cracked heat exchanger. After that we bought new smoke/CO combo detectors and also bought ones that plug into an outlet and have a read out for CO on them. I recommend backing up your detectors with something like this- https://www.amazon.com/Kidde-Carbon-Monoxide-Digital-Display/dp/B016T9SDXQ/ref=sr_1_46?qid=1575043083&s=hi&sr=1-46&th=1

> Speaking as an electrician

Thanks very much! That is good to hear coming from a professional. I was proud of my little workaround hack, but I have never read about it anywhere else so I wondered if I was missing something important... but it really does work (I've used it during a couple of outages now). One useful thing to do is to use a little label maker to label the relevant outlets inside the house with "GENERATOR", just to make clear that they aren't usually going to be working. It's also good to make sure that whatever extension cords you get for coming from the generator to the house inlets has a round end for where it's going into the inlet. Some extension cords have the additional tab sticking up which makes it hard or impossible to fit into the inlet socket. Kind of hard to describe, but you'd know exactly what I mean if you see the inlet. Unfortunately the ones I got don't seem to be available any more on Amazon, the product page has gone away, but they looked a lot like these:

https://www.amazon.com/ParkPower-Marinco-150BBI-RV-Charger-125-Volt/dp/B000NV0V8C/

And the extension cords for generator to inlet are these:

https://www.amazon.com/gp/product/B0009IAXSW/

Notice the female end of the extension cord is round, so it'll fit inside the inlet socket. I think I have the 100 foot and another 50 foot of the 10 ga, for getting from the generator on the rear deck to the two different inlets on the house. The garage one is a bit further away, toward the front of the house, so I need the 100' for that. Usually I'd try not to run so long, but when running the generator in an emergency I'd much prefer for it to be hidden in the rear of the house, not visible to the road. Being 10 ga gives me a bit more room to play with 100' length without losing too much power to the cord.

Other than those, it's a pretty standard job that anybody who's a little bit handy can do - you might also need a 1 7/8" hole saw for the inlet, assuming you have wood walls (we have cedar siding). I used something like 10 or 12 ga house wiring between the wall - I think it might be 10 ga since I remember hemming and hawing on which to use, I believe I went heavier just to be on the safe side. It's a bit intimidating for a non-professional to work with wiring stuff up, but since it's not connected to the actual house wiring, that takes some of the fear out. Just have to make sure you get all the right wires in the right places (not too difficult) and tighten everything up. Also a little bit stressful hacking holes in your exterior house wall, but once it's all sealed up again it's pretty cool knowing you can now get power inside without having to leave the window or door open.

I also have a Kryptonite Stronghold anchor in the back yard next to the deck, for chaining the generators up while they are running, so nobody can just pick them up and run off (a downside of having portable generators is that they are, well, portable):

https://www.amazon.com/gp/product/B000LF903M/

I dug a hole and then filled it with high stress concrete, then left it to dry for a week or two, then drilled the holes for the bolts and installed the anchor. For chain, I used the strongest stuff I could find at Home Depot. The padlock likewise - just the most beefy, secure one I could find. On the generators themselves, I have installed the security addition to the handle:

https://www.amazon.com/Honda-63230-Z07-010AH-EU2000i-Generator-Deterrent/dp/B004DQY6B6/

This doesn't make it 100% secure, but it's better than just having the plastic handle which is easily broken. Security is a matter of layers - you don't depend on anything being 100%, but you hope that everything will serve to either deter or else slow the thieves down enough so that either they don't try, or else you will be alerted in time to stop them.

Finally, I have a couple of failed circuit alarms, which go off when power is lost:

https://www.amazon.com/gp/product/B0077Q9NC6/

I figure these could be on the extension bar inside the house while the generator is in use, then if it goes off or is being stolen then I will get an alert when they unplug the extension cord. I am using one of these alarms in the garage now, for the chest freezer so I'll know if that circuit trips out for whatever reason (avoid thawed out freezer, never fun).

Anyway, hope that helps anyone else who might be thinking about a similar setup - the Honda EU2000i is a great little generator (I also have the Companion), and with a little forethought you can make it much easier to use in your house in emergencies. Oh, and one last thing - I also have a large folding plastic table, which can be used to put over the generator if it's raining outside when you need to use it. Obviously the generator can't be too near the house, because of risk of carbon monoxide, so being outside puts the generator at risk of exposure to the elements. One of those folding tables, you can get from any department store, is useful for putting the generator under something. If the rain is especially heavy, I can put an additional tarp over the table, which can also cover two sides, and a couple of cinder blocks makes it ok in the wind.

Incidentally, this is a good battery powered CO detector, great for emergencies if you need to run a Buddy heater inside the house, or make sure the generator exhaust isn't blowing inside:

It honestly depends where you live, such as a tenants union that you can research and pursue follow up. For example, this is Seattles: http://www.tenantsunion.org/en . I think it comes down to how much effort you want to deal with this. Do you have natural gas coming in to your place? If not it really may not be worth it. If you're very concerned, you need immediately remedy, and the landlord is dragging their feet, here's one from Amazon from $20 https://www.amazon.com/First-Alert-CO400-Battery-Monoxide/dp/B000N8OYXI/ref=sr_1_2?ie=UTF8&qid=1475004662&sr=8-2&keywords=c02+detector

u/bdporter · 2 pointsr/sousvide

> The elevated temperatures of the cast iron is supposed to also allow a more complete combustion of the propane, which further reduces the CO concern.

Unburnt hydrocarbons (which could make the food taste bad) may be a bigger concern than CO. However, it doesn't hurt to be safe, so you can always get a CO detector if it adds to your piece of mind.

u/stothet · 1 pointr/chicago

If you rent, I recommend buying one you can plug-in (it has a battery backup too). It also has an optional longer cord if you want to plug it into a power strip or something and place it on a counter/table. This one got praise from Consumer Reports and when you move you can take it with you.

u/Sierrasclimber · 1 pointr/vandwellers

Do you sleep on the floor? I really wouldn't worry about propane. It stinks and is heavier than air. Your supply of it is pretty minimal. AKA I think it would be hard for a couple bottles to leak and kill you. Also doubt your van is that air tight. If you're worried always disconnect the bottles. Very unlikely, you disconnect the bottle, it doesn't leak (if it disconnects and is leaking you'll know; just sniff it), and then some how during the night starts to leak. While connected; yeah people manage to empty a propane bottle all the time (accidentally turn stove on or bad seal)

Check for yourself google:
Propane kills rv occupant
Carbon Monoxide kills rv occupant

What I got: Propane explodes and kills; CO kills people in their sleep. CO kills way more people.

An incomplete burn sounds to be rare and relatively easily identified in advance. Another quote from the site linked above:
>Carbon Monoxide is the product of incomplete gas combustion often because appliances are improperly adjusted. Properly functioning propane appliances will produce what is called an "ideal burn" during combustion and present no danger of Carbon Monoxide poisoning.

and

>Several products of incomplete combustion are easily visible and if noticed...

Additionally, the Mr. Heater Buddy OP is considering is a catalytic heater, and doesn't produce an open flame (cleaner).

Practicing an abundance of caution, inexpensive CO detectors are available and should be used.
