Such concern is inconsistent with the present reality. Gasoline for a lawnmower incorrectly stored in a garden shed or garage is explosive. The propane tank for the BBQ can easily destroy a chunk of you house if placed too close to an open flame. The OTC medication in your bathroom can also poison you if you're careless. There are many creative ways in which the electric supply of your home could result in your death if not treated with care. The examples are practically endless.

Even just a half decent kitchen knife will be razor sharp and capable of removing a digit or two if handled incorrectly.
