CHARCOAL GRILLS 1. Operate charcoal grills only outdoors, never inside an enclosed area, such as your home, enclosed porch, garage, tent, vehicle, etc. Even if you've finished grilling, and you assume all the coals are extinguished, they're still producing highly toxic carbon monoxide, so keep your charcoal grills outside at all times. 2. Don't wear loose clothing, especially long sleeves, while grilling. 3. Charcoal grills tend to flare up, so keep a fire extinguisher handy. 4. Use charcoal lighter fluid to light new coals only; don't use it on coals that are already lit. 5. Don't substitute approved charcoal lighter fluid with other flammable substances such as gasoline. -- U.S. Fire Administration
