When a decomposing sperm whale spontaneously exploded in the town of Tainan, Taiwan whilst being transported for a postmortem examination. (Source: Wikipedia) The exploding whale splattered blood and whale entrails over surrounding shop fronts, bystanders, and cars. No one was hurt, but likely quite a few people were shocked. Plus the blood and other stuff that blew out on the road was disgusting, and the smell was really awful.

This just goes to show that no matter how unlikely a disruptive event is in the context of your supply chain, it could still happen and you should be prepared when it does.
