No, it's not.
Ever seen turn of the century green glass? It's prized by collectors. It's also radioactive, and contains uranium. You might be surprised what's out there. Watches, glow in the dark alarm clocks, aircraft instruments, etc.
If the glass happens to break? Did you know that one of the means in venting the static system in many aircraft was breaking the glass on the VSI? It's not that big a deal. It really isn't.
You may have heard of the concept of making a mountain of a mole hill. Put the mole down carefully and back away. Nobody gets hurt. Especially the mole.
