No, but the lady pictured standing in the hole where the fireball occurred confirms that it had pretty much gone out and cooled down before the demolition occurred.
Did you try throwing that gas can through a steel beam yet to see how much of it vaporized in the initial explosive fireball? Let me know how much of it pooled, how long it burned, and when it had cooled enough to safely stand in the area again. All of that happened before the building demolished itself.
When I find a 10,000 gallon gas can I'll try it and get back with you.
