I wouldn't be worried about it... BP motors do CATO, but the propellant burns so fast that even if you're launching D motors from 15 feet, the fireball out the front of the rocket usually burns out within 10 feet of exiting the tube
I've had lots of those...
Composite CATOs are fun because usually the propellant goes out (rapid drop in chamber pressure, like one big chuff), but I remember Alex McLaughlin's P motor CATO at BALLS last year while I was loading my doomed M project on the pad... when the case fell back down onto the pad leg, it knurled over the end and trapped the propellant inside, meaning it sat on the ground and flamed for a long time. Even at my "vulnerable" distance (I was at the 500 ft pads, this rocket was at the 1500 ft pads), it was no big deal. 15 feet of distance is plenty for BP motors because the propellant burns really fast outside the case.
Anybody else got CATO stories?
