Two quickies.
#1 - One of the first calls I was ever on - I was an EMT at the county fair. On the way home one evening, see a rusty little POS (escort? civic?) lurch to a stop approaching the road. My partner and I pull over and approach.
"Good evening, sir, having a little problem?"
"Yeah, it's been doing this all day"
Smell HOT. HOT NOW. Shine light on hood, notice small brown spot the size of a dime.
Now the size of a nickel.
Now the size of a quarter.
Look underneath car, see small flaming from engine. Look at partner.
"Richard, fire...sir, step out of the car, please" After we dump our dry chem and five squads dump theirs (looked like a fire base ala VN with all the empties lying around.) The local FD finally shows and puts out engine compt. w/an 1 1/2" hoseline.
In the rain. So much for spiffy uniform.
Second story. 10 years later; I'm at a local coffee shop w/ a buddy who's also on the job. We've just gotten off shift. We overhear several "oh my's" from the LOL's behind us. Turning (coffees in hand) we notice a large amount of steam-turning-to-smoke comiing from the car across the street. See the owner come out, and for the hood release.
[MST3K]don't do it, buddy...don't do it[/MST3K]
Of [i]course[/i], he opens the hood, and, as we all know, heat+oxygen=[red][b]FIRE[/b][/red]. Of course, my buddy and I are "screen talking" to the window. "Ahh, ya dummy, we told you not to open the hood". We start back to our breakfast, and hear one of the LOL's say "It's going to explode".
Without thinking, I say out loud "burning cars don't explode".
She replied [haughty]Oh, really? How would [u]you[/u] know?"
I turn and partially stand, so she can see the uniform, and, smiling, say, "Well Ma'am, in my ten years as a firefighter, and the dozens of burning cars I've responded to, I have yet to see one explode. The gas tanks occasionally rupture, but that's just a big, burning puddle when you get down to it".
She looks up, and her jaw hits the table...she stammers, "Well, they explode in the movies"
I told her "Ma'am, they explode in the movies because there's two to five pounds of plastic explosive under the rear seat for effect".
Wound up having a pleasant breakfast and explaining step-by-step what the local FD was doing as they extinguished the car.
Just remember - once the car burns - it's an insurance writeoff. After the cost of replacing the wiring, computers, and interior, it's cheaper to buy the customer a new one.
