To prevent carbon monoxide poisoning on a propane heater, make sure that your heater is suitable for indoor use. When you run the heater, it should always be in a well-ventilated area with proper air circulation. Installing carbon monoxide detectors on every level of your home is also essential. If you have any questions about using a heater indoors, contact a local heating and oil company for more information.

No. Removing the cause of concern will only lead to deeper concern. You cannot use any fire-powered appliance like a fireplace or furnace without an escape route for the smoke and fumes. If you remove the flue intending to repair or replace it, you should only use the fireplace, wood stove, or furnace once the flue is in working order. If you cannot replace the flue you have removed, call a chimney repair professional immediately.

When a carbon monoxide alarm goes off, you should always take it seriously. Infrequent and occasional chirps often point to a low battery, a faulty device, or dust buildup (this usually affects smoke detectors and not standalone CO detectors). A continuous alarm signals an emergency, and you should immediately evacuate and call 911. When it comes to carbon monoxide in your home, it’s better safe than sorry.

According to the National Fire Protection Association’s Code NFPA 25 (titled “Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems”), private fire hydrants must undergo inspection once per year, with an accompanying flow test and any necessary maintenance performed on the same schedule. Keep in mind that your town, city, or county may adopt more or less strict testing requirements.
