Predicta - Tube type 21SFA - dangerous?

The Dachshunds were inside, so it couldn't have been them. Temperature drop too rapidly was the most likely cause. It had been on a tester, cooking at 9 volts, so the neck was very hot. I took it right outside, where the temp couldn't have been more than 40, and was likely closer to freezing. Now that I think of it, scratching the face when I set it on the pavement could have contributed greatly as well. All I know for sure is that I'm never putting duds on the back patio again. I'll walk them right out to the curb on trash night from here on out.
