|Keep a small gas can in your car to use in an emergency. It is important not to leave a full gas can in your car, but an empty one. Just use it when you need it, don’t use the gas can you fill up for your lawnmower.
Having a certified “gas can” is important, because other containers can be very dangerous. If you had to walk a couple of miles with a gallon of gas in a clear water jug, the sun could be magnified by the plastic and light the jug on fire. Don’t be that guy.
