The rat trap is a fantastic combination of simplicity and efficiency. There isn’t much to it – just a wood pallet, a coiled spring, a latch and a bar – but the results are impressive. The rat trap we know today was originally patented in 1897 and has remained largely unchanged for more than a century for one reason: it works. However, the device comes with its own set of hazards for humans. The kinetic energy stored in the coiled spring is indiscriminate and comes at you in fewer than 0.004 seconds. Despite this fact, it’s easy to become complacent when handling a rat trap. The original patent called it the “Little Nipper,” which sounds almost harmless. In fact, the term “rat trap” is a little misleading since the intent is not to trap rats, but rather to kill them (I guess the name “Rat Spine Snapper” didn’t poll well with focus groups in the 1890s). The rat trap has a job to do, and it does it well, but not without risks. This is also true of many of the jobs utility safety professionals engage in every day; we do our best to execute them well, but they have their risks.
