Can I Replace an Electric Smoke Detector with a Combined Smoke and Carbon Monoxide (CO) Detector?
The problem with a CO detector combined with a smoke detector mounted on the ceiling is that smoke rises and CO is heavier than air. So by the time a ceiling mounted CO detector goes off you've likely been dead for quite a while. CO monitoring needs to be done low, there are several stand alone CO detection units that plug into a standard wall outlet and have on board battery backup. Companies that sell CO combined with smoke detectors clearly did not research the product they are attempting to detectâ¢ Related QuestionsDo electric appliances produce carbon monoxide?An electric appliance could produce Carbon Monoxide if there were a malfunction which caused the materials of the appliance to burn. However, it is unlikely that this would produce a significant amount of CO. Besides you would most likely notice the malfunctioning appliance, a burning smell, or smoke and flames. It would most likely take a large amount of material to burn within an electric appliance to increase the CO to dangerous levels in a house. Although, as a previous answer stated, even making toast produces CO.If you're worried about it, buy a CO detector. They're fairly cheap and most are paired as dual purpose smoke/CO detectors------Can a gas fireplace be left on overnight?A gas fireplace can definitely be left on over night with some specific requirements.The vent must be in excellent condition with no leaks. The vent should incorporate triple wall pipe which allows for replacement air coming in through one chamber of the vent pipe, with the air coming in pre-heated by the hot exhaust which assists with consistent combustion. A high quality CO detector must be in place and functioning properly.Another supply of fresh air such as an open window is also important.Finally a properly functioning smoke/fire detector and alarm must be in place.------How much room do I need to avoid carbon monoxide poisoning?I can't really say "you'll be okay", because it's about how our body reacts, but I'd say yes, it's enough. There are underground parkings where engines are running all the time. Also you can buy a little carbon monoxide sensor which will yell at you if it's too much.Just type "carbon monoxide sensor" on eBay; there are plenty of them for a cheap price. All are supposed to do the same job. Basically, they are similar to smoke alarms, but just aims at different stuff. I have both at home------Do landlords have to provide a washing machine?Absolutely NOT!LLs are required by law to provide the followingA steady supply of Electricity, Gas and Water.Comfortable living environment - in countries with winter this means a good source of heating ( HVAC / Ductless / Radiator / Portable Units ). Please note that AC is not a requirement. Smoke and CO detectors. The LL is not required to provide the tenant with a Stove, Refrigerator, Washer, Dryer, Microwave or any other equipment. LLs only include some of these equipment to make their units more attractive to potential tenants. However, it should be noted that the tenant can be held responsible for any damages to those included equipment.------In California, are landlords required to insulate the tenants garage?The California Department of Consumer Affairs publishes a tenants' guide of premises is discussed starting at page 37 of the guide.Inability to keep the premises warm enough may breach the implied warranty of habitability. Additional research and analysis would be required before one could render a definitive opinion.Significant leakage of carbon monoxide into the premises definitely would breach with warranty of habitability. If you have not been suffering any of the symptoms of CO poisoning (see Frequently Asked Questions), then there probably is no significant CO leakage. However, it would be prudent for you to purchase a CO detector------Physical processes taking place inside Germanium detectorsIt is not pair production. Although the energy of the Cobalt gamma rays is in principle greater than the 1.022 MeV needed for to create an electron and a positron, the cross section is negligible below 4 MeVBoth photoelectric and Compton effect processes are important. In photoelectric absorption the electron gets all the energy of the photon, and as the electron energy is what's actually recorded these events appear as a sharp peak on the energy spectrum produced. For Compton processes the electron gets some of the energy (the recoil photon gets the rest) so these events appear as a continuum------How effective are the smoke and carbon monoxide combined detectors, considering most CO detectors are placed on lower levels on walls and smoke detectors need to be on the ceiling?CO detectors can be placed at any height. Carbon monoxide has a neutral weight, it is not heavier or lighter than air. Without any air movement it will stay at the height that it is originally disbursed. But it will travel with air currents created by fans, HVAC systems (air conditioning and heating), or people walking around. So the most ideal location will vary in different houses, with different HVAC systems, and different habits.How effective are the smoke and carbon monoxide combined detectors, considering most CO detectors are placed on lower levels on walls and smoke detectors need to be on the ceiling?------Gas-fired water heater safe to have in living area of home?According to UNI 7129 regulations yes, it's regular to have a direct vent (category B) gas appliance if is present a 'permanent vent' calculated according the following formula: vent_aperture_size cm^2 6 x appliance_rated_power kW if result is bigger than 100cm^2, else 100cm^2. Gas usage is not allowed in bedroom or bathrooms. According to Florida laws I don't know, but I'll put a carbon monoxide sensor or I'll switch to class-C (sealed chamber) appliance so there's no link between fire chamber and living-space (both inlet and exhaust are directed outside) -> back-drift is impossible (so no risk of CO poisoning).------Will I get carbon monoxide poisoning for leaving a gas burner on for 3 hours?CO poisoning occurs when you inhale more CO than you exhale, and most non smokers exhale only 1-3ppm. So if operating gas stove generates over 3ppm in your breathing zone (quite likely if your are both in a small kitchen with doors and windows closed and no other ventilation), then your CO poisoning has begun.Note your poisoning will last after your exposure ends, until your arterial, venous and tissue CO levels return to pre exposure baseline, which you measure with a plastic bag and any professional CO detector that displays Accurately From 1ppmWill I get carbon monoxide poisoning for leaving a gas burner on for 3 hours?.------When buying a new home, what are some of the first things you should do before moving in?It is easy to get excited about moving into the new house, but there are a few things that you need to check for your familys security.Change the LocksCheck for Plumbing LeaksInvest in Pest ControlElectrical Upgrades if neededrefinish the hardwood floors in the major areas of your homeInstall a Detachable Toilet SeatClean AC Condensers and EvaporatorsCheck Smoke and CO Detector Dates and Replace, as NeededTest your sump pump before the beginning of the rainy seasonAdd Door and Window AlarmsTackle major maintenance tasksA professional home inspector will check all these things.

Helpful post to read:Home Inspections That Save Buyers Money------rewiring a basement lightRob, thank you for explaining what you are doing, but I got that from your original question. What you need to do is re-wire the complete lighting arrangement in your basement. My suggestion is to remove what's there and put in exactly what you need in each room/area. If you do not know what to do this wiring please simply hire an electrician to do this job for you. If you are making this into bedrooms there are several other VERY important codes you MUST follow, such as AFCI protection for any circuits in the rooms, smoke/CO detectors, means of egress, etc------Is it okay to carry a carbon monoxide detector in your plane checked luggage?Carrying the detector is no problem. I recommend you either remove the battery or insert the power-disable tag for a permanently fitted battery. You do not want the alarm going off in your luggage when you are not there since alarm devices in baggage are not permitted.If you're trying to carry calibration equipment for a CO detector, in particular permeation devices, these must conform to IATA special provision A41 and must be carried in checked baggage. You may want to consult the airline beforehand.Is it okay to carry a carbon monoxide detector in your plane checked luggage?------Does a Duracell battery of today hold more energy than a Duracell battery from 30 years ago?Thanks for the A2A. The standard battery capacity has not changed much from what I have seen using them in say my smoke detector / CO detector. As others have said there are improvements, which might yield greater capacity per unit of alkaline paste. But as also noted these allow reduction in weight and material to keep things roughly the same. Some styles of battery may hold more capacity as touted on their packages but the devices in which they are used often draw more power and thus use up standard batteries faster. I am thinking here of digital cameras. I would defer to as well------Exhaust fumes seeping into our 4th floor apartment at night through bathroom and shower vents/fansPLEASE seek professional assistance immediately.There are two main issues with exhaust that can make you feel ill like this: Carbon Dioxide and Carbon Monoxide. Both are harmful, if not fatal, if the percentage present in the air you breath is too high. You DESPERATELY need to install a carbon monoxide detector, and contact your local housing authority. This is not something to be taken lightly, nor fixed by amateurs. HVAC follows particular code and regulations in many countries. I suspect that your venting exhaust is either too close to the garage venting, or is venting INTO the garage------How do you explain PMS scientfically?From my perspective as a toxicologist, both PMS and PMDD symptoms are caused by endogenously produced CO (from HO-2 breaking down heme protiens in the endometrial lining), which peaks the day that menses starts. This CO can be measured in exhaled breath with any portable CO detector that displays from 1ppm. With my patent pending methods, it takes less than 5 minutes to measure arterial, venous and tissue levels of CO just by exhaling into a plastic bag. Hormone levels are not the cause; they are unchanged from the PMS phase to menses phase, when CO falls from its max to its minimum------More points vs. precisionNot knowing your situation in detail it is hard to offer detailed advice, but here is one course of action that should be available to you and will give a sufficient energy calibration:That gives you five points which is sufficient for a full linear fit with uncertainties.Now that I see the OP's data with it's very good signal to noise ratios (I was using a rather aged and low activity barium source), I would modify this as several of the barium lines are usable, and there appears to be a K-40 background in the detector visible in the Co-60 data which means that the banana is not actually needed------Have you seen the new smoke and carbon monoxide detectors with 10 year batteries that last for the life of the device?I've seen those sealed detectors which have received mixed reviews and have not been impressed. There is some merit to regularly testing smoke and CO detectors and replacing their batteries at regular intervals even if they have not begun chirping. I have also tested so-called long-life lithium AA cells that claim to have a 20-year shelf life. Despite being much more expensive, they did not last as long for me in smoke and CO detectors as do alkaline cells. Failed detectors cost lives and is no place to scrimp in my opinion.Have you seen the new smoke and carbon monoxide detectors with 10 year batteries that last for the life of the device?.------Are there any harmful effects of living in a basement apartment?A properly finished basement is like any other living space... generally safe. Like any other home, unhealthy situations arise when water intrudes the space. This can be from a leaking roof or a leaky basement. The usual safety gear applies, smoke and CO detectors, and regular inspection of the area for any problems that could cause health issues.
