The torches have a safety feature called a "fracture groove." If the tip hits a solid object or if the torch is dropped, the tip will snap off so that the cylinder does not explode.
But the feature does not work in many instances. That is one of the defects.

- The fracture groove is supposed to break like this when the cylinder is not defective.

But often the fracture groove will not break, because the force is too low. However, a defective cylinder will rip open and explode anyway, usually right at the neck. |
Sometimes they cylinders are not welded properly and leak at the neck. When lit, they ignite at the neck and are dropped because the flames burn the hand, and when they hit the ground they break wide open.
This is what a good weld should look like for comparison.
