Burn Blankets?

[MiTTMedic]

You see them everywhere in theater...the orange tube we call the "Burn Blanket". I've replaced a few of them that have broken from mis-handling and leaked out their "snot", but never used one myself. My questions are:

Has anyone that has used them? Thumbs up/down? Lessons learned?

Where do you store yours in an MRAP? I've seen it stored inside & out in various places, most with good reasoning.
