In cases where the satellite is orbiting low, Kessler shouldn't be a problem. In this case the satellite was at 300km and the pieces would decay in less than a year. Even if pieces were pushed into a higher orbit by the explosion, they would still dip down to 300km periodically and decay just a little longer.

Ah that is great to know. I believe the Chinese asat test was around 500 or so miles and it caused a real mess of debris.
