Handling: At the park or track it's common to carry fuel in a quick-fill bottle. To insure that you don't get your fuel mixed up with someone else's (who might be running a different mixture) label your fuel bottle with your name. If you're running multiple RCs with different fuel mixtures, color-code your bottles to avoid mix-ups.
Storage: As with gas cans stored at home, store your nitro fuel away from open flames (next to the hot water heater with its lit pilot light is not a good storage idea). Keep the container tightly capped to avoid evaporation. Don't store nitro fuel in a damp location either as the fuel attracts moisture and water in the fuel will render it weak and could be harmful to your nitro engine.
