 In this video which looks like it happened in Asia somewhere there is a chemical truck on fire on a freeway. There are a bunch of fire crews all around trying to keep the truck cool but the fire is rapidly spiraling out of control. Around half way through the video the truck loses it and explodes in a HUGE fireball that engulfs the surrounding firetrucks and guys. You really have to watch the video to get an idea of how big of an explosion it really is. The fire cloud stretchs up over the video camers recording the fire. Near the end of the video it says four people suffered burns but no one was hurt in the giant blast.
