DOF relates something from a Survival (!) class he took in high school:
“Suppose you see a man down. He’s just lying there face down. What’s the first thing you do?”
Our guesses ranged from “Check his pulse” to “Call an ambulance”.
“Hang back and try to figure out what got him,” he said. “Any power lines down? How about gas? If he’s been shot, look around. You can’t do him any good if you are victim number two.”
In context of the news story he’s relating the anecdote to, it makes perfect sense.
I may use it as a Safety Minute on a business call some time soon.
