C: Yes. The people are dead in the trucks. Oh, ---- . I'm sorry. They're exploding. Can you hear them?

C: I'm sorry.
D: Is it a tractor-trailer?
C: Yes, sir.
D: Are there any placards on the tractor?
C: Any what?
D: Are there any warning placards on the trailer?

D: OK, ma'am?
D: OK, take a deep breath for me. I'm going to stay on the line with you until we get somebody there. ...
C: 95 northbound is on fire. Southbound is on fire. It keeps on, it's flammable obviously. The black smoke - I'm going to have to (breathing heavily) oh, my God. Oh, please help these people. It's on fire.
D: How many explosions have you heard?
C: I've heard about 15, at least. So far, at least. Oh, my gosh. They're still going off.
D: Can you tell how many cars?
C: No, sir, I can't. This black smoke. And actually you'd better get the fire department because it's heading over here toward the woods.
D: OK, I've got people coming from both directions to you. I've got a ton of equipment coming out there. ... Let me ask you this. Can you see anybody running away from the vehicles?
C: No, sir. They're dead. ... Nobody's come out of the vehicles. I just know, I was almost involved in this accident.
D: Is it like a tanker trailer?
C: Yes, sir.
D: So it looks like it might be hauling gas or diesel fuel, or some kind of fuel, like liquid?
C: I see the helicopters now, thank God.
D: Yeah, that's Trooper 8. They just came from the airport.
C: OK. Oh, my God (sobs). Oh, my God.
D: (To someone at 911 center) We've got a tanker on fire. We've got a tanker on fire.
C: Yes, sir?
D: Just take a couple more deep breaths.
C: I will, I'm sorry.
D: That's OK. You've just seen probably the worst thing you'll ever see.
C: (Sobbing). It's still exploding (long pause).
D: Is anybody trying to go near the vehicles?
C: No, sir. Everybody knows better, it's still exploding and fire.
D: But you can't see how many vehicles are up there, right?
C: I saw three of them, two to three. (Sirens in background). Fire department's here now. (Pause) They're still exploding.
