One of the places I worked in required that everyone get Fire Extinguisher training. During the training the Fire Marshal described the different types of Extinguishers and how to use them. Before we got to actually each put out a fire, he asked one of my co-workers this, "You have a Chemical Fire Extinguisher in your hand and the guy next to you is on fire, what do you do?"
Her response was she wasn't sure. So the Fire Marshal responded, "Let me rephrase, you're on fire, he has the extinguisher, what do you want him to do?!"
She immediately said, "Put me out!"- The rest of us made note that she wasn't the person to have around during an emergency!
