What is considered a Class 1 explosive?

Class 1, Explosives: An explosive is any substance or article, including a device or pyrotechnic substance, which is designed to function by explosion (i.e., an extremely rapid release of gas and heat) or which, by chemical reaction within itself, is able to rapidly conflagrate or detonate.

What NFPA Class is propane?

NFPA 58
Storage of LP-Gas is covered in NFPA 58, Liquefied Petroleum Gas Code, while storage of flammable liquids is covered in NFPA 30, Flammable and Combustible Liquids Code. What is important is that propane is not a flammable liquid. It is a flammable, liquefied gas.
