(WOLO) COLUMBIA,S.C., -- The National Fire Protection Association says even if you have grilled out before, it's never a bad idea to be cautious while cranking up your grills. Safety Advocates say use charcoal and propane grills outside only. Never leave them unattended. It's also a good idea to check tanks for leaks before actually using them, and in the case of charcoal grills, make sure coals cool completely before dumping them out to prevent starting a fire. Officials say grills can be dangerous if not used properly. Make sure you set your grill up in an area that in away from small children and pets. (source: CNN)
