A very simple one happens when disposing of broken glass containers. If one uses the floor models, that are about 3‰?? tall, they hold a lot of weight. I‰??ve had instances where I pick these boxes up, and the sheer weight forces a glass pipet to come out the bottom, and through my hand. It‰??s only happened to me once or twice (I did finally learn), but it happens quick and easy. That glass goes right through the box quicker than you would imagine, with no issues.

And some of the ones mentioned have happened to students here as well. Breaking a beaker by hitting the edge of the counter seems to be one of the more frequent ways, and usually leads to bigger cuts that require stitches and attention.

Good luck

When it stuck, torque was applied and the male fitting snapped, leaving a sharp edge that made a cut to the back of the hand above the thumb holding the flask that required several stitches.

Pressure not applied in a straight line, (both objects held freehand) pipette snapped, and punctured the hand holding the filler in same position as above injury. In addition to stitches, some nerve damage plus fainting at the sight of blood.

I‰??m doing a training next week for undergraduate students and I‰??d like to make the point that it‰??s not always the chemistry that creates the problem. The example I have in mind could involve hot glassware that breaks when someone tries to pick it up and drops it, but similar events would be helpful as well.
