My Site Induction Safety Briefing
They showed us a map of the bits they had been able to find[1] after someone dropped a large slab of high explosive on a concrete walkway. Apparently from eye-witnesses some distance away, it didn't go off until it was picked up -- the post-mortem (so to speak) engineering analysis suggested the edge of the slab scraped along the concrete and that was sufficient.
[1]There were two people involved, they only found one head.
