Intertech surge protector bursts into flames

Watching the U.S. Open when SO and I hear a loud pop behind us. Look up to an outlet on the brick fireplace and the surge protector on it is on fire. Pretty good sized flames but I was able to put the fire out. Turns out the power line between the house and the power pole had dropped down and damaged the electrical ground.

House had surges until power co fixed it, but all the other surge protectors worked well.

PSA. Some older Intertech surge protectors have fire issues. We were lucky to be at home.
