    If a large enough amount of an explosive, even an otherwise very safe propellant catches fire it may not need to be confined in order to explode.
    The weight of the material acts to effectively confine the inner mass longer than it takes for the heat to flash over into the interior.

    Heat from a nearby fire can also cause double base propellants to sweat nitroglycerin.

    High explosives don't need confinement. Soldiers have been known to heat meals and coffee over a burning brick of C4. As long as you don't shock it, it doesn't detonate.

    Smokeless powder mills used to occasionally have "flares" in the mixers. Several hundred pounds would burn in a short time. Released a lot of heat, but no shock wave. This was even true of double-base powders.
