Beware! There may be an immeasurable hazard in your bathroom, your glass shower door! It can happen in an instant; shower doors spontaneously shattering, sometimes while a person is showering, resulting in injuries of various magnitudes. Framed or unframed, something as simple as closing the door a little too hard, worn rubber stoppers, or damaged runners, typically from wear and tear, can create a small unseen fractures in the side-edge of the door causing the glass to explode at any time, like a ticking time bomb. CBS Philly, Jim Donovan, reports.
