An explosion starts pressure waves in the medium where it happens. Explosions are categorized as deflagrations if the pressure waves are subsonic and detonations if they are supersonic. When a detonation happens, the supersonic pressure waves are named shock waves.

Unintentional explosions.

Unintentional explosions can be caused when chemicals are mixed together, or if pressurized containers or flammable materials are heated or exposed to flames. To cause

an explosion, pressure does not have to be present but is always a result of an explosion.

There are a number of safety measures that are used to prevent unintentional explosions. Many countries require that chemicals, fuels, and pressurized containers that may explode be labelled with warning labels. As well, many countries have regulations restricting the possession and use of potentially explosive chemicals to appropriate industrial and research uses. Many countries have transportation regulations that require potentially explosive chemicals, fuels, and pressurized containers to be transported safely.

Intentional explosions.
