A typical home may have several different appliances that run on gas. Your clothes dryer, oven and hot water heater are a few. It isn't always a repair that leads people down the path of danger when dealing with gas. Sometimes, it may just be necessary to move the stove because of a floor tiling project or to move a dryer away from a wall that needs painting. Some homeowners feel like a hot water heater replacement is within the realm of their capabilities, and this is when accidents happen. Like water, gas will always find a leak. So while you may have done a good job in cutting off the gas supply line and moving the stove, you may not have been as careful when hooking it back up. The end result of what you thought was a simple fix could lead to accidental carbon monoxide poisoning -- something that kills more than 400 people per year in the United States alone [source: Medscape.com].
