Porter cable orbital sander caught fire - Family Woodworking

I had something similar happen once, but it was totally my own fault. I was using a belt sander to flatten the back of a very abused chisel. sparks flew up the vacuum's hose, into the dust bag, and it began smoldering.

Your experience however, seems quite a bit worse. Any chance the sandpaper hit a bit of metal, sending sparks? Hard to believe the motor brushes spark enough to ignite the dust, but maybe. In any case, this is really dangerous. Have you thought of contacting the consumer products safety agency? Please let us know the outcome.
