Question about safety issues when converting from oil heat to gas heat.
Q: "A natural gas shale line from Marcellus Shale gas in Pennsylvania may extend into the Northeastern states in the next year, if approved (Quote from CBS 12/3/2014) We currently are using oil heat. Replacing the furnace with natural gas will save us a lot of money. How can we avoid the health risks associated with natural gas?"Thanks Tom.
Answer: Continue using carbon monoxide alarms and smoke detectors as you have been doing, remembering to test them monthly and change batteries once a year. I would also suggest you add a Scentry III Gas Shut Off system on your main line into the home as well as Safe-T-Alert Combustible Gas Alarm or a Safety Siren III natural gas alarm near your natural gas appliances such as ranges, fireplaces, etc.
With the Scentry III GFRAB, you can add additional remote sensors, a battery back-up and a connection to a home monitoring system if you have one or plan to get one.
Remember that natural gas is lighter than air and "puddles" at the ceiling above the appliance using it. If near an open stairway, the gas will go to the top of the stairway.
An annual furnace tune up with filter change is needed with gas furnaces as well as with oil. If you want the best disposable furnace filters, use the 4 inch or 1 inch Safe Home filters.
Thanks for your questions.
