Here and there a check of the springs on a trampoline can uncover any safety issues before they become a concern. Take the case where a badly stretched set of springs that can literally double in size can create gaping holes and hence a safety concern of falling through the large gap. In this case the best thing to do is to replace the springs.
If springs fail on a newer unit, you may get the replacement springs sent to you under warranty.
Finally, you can get trampoline spring covers to increase safety on trampolines with exposed springs.
