Making sure your appliances work and are tested often can go a long ways towards natural gas safety.  This will help potentially prevent issues you may have with gas appliances over the winter. Jake Dukett, a Natural Gas Public Awareness Supervisor for Ameren Illinois says that it is important to inspect all your appliances. 

Sometimes those flames will turn orange or yellow and that can mean several different things but it could be something worse like a CO Problem. Flames are different colors based on the temperature of the fire you are looking at. If you think you have a problem, make sure someone is able to inspect it. 

If you do smell rotten eggs, there could be a gas leak and you need to take immediate action including calling Ameren illinois at 1-800-755-5000. 

If you can't remember the Ameren number, it's ok to call 9-1-1.  They will notify Ameren for you.
