The law of explosives covers dangerously volatile substances, including gasoline, oil, dynamite, and blasting caps filled with highly explosive compounds. Under the Police Power given to the states through the Tenth Amendment to the U.S. Constitution, state and local governments may regulate the storing, handling, transportation, and use of explosive substances.
