I feel that this article missed a more obvious issue: black hole temperature and mass enjoy an inverse relationship, so a truly tiny black hole could potentially kill you with its radiation alone. Ironically the mass they indicate (1.4 x 10^14kg) would have a temp of nearly a million Kelvin, or 1,578,295,386 degree Fahrenheit.

I'm pretty sure the x-ray flux would kill you before it ever touches you, but I could be wrong. For much MUCH smaller black holes, that temperature can increase by a staggering amount. For example a black hole with a mass of 140,000,000kg would have a temperature over 1.5 quadrillion degrees Fahrenheit.

Now of course the source of this radiation would be tiny, but the flux would be intense. Some napkin math suggests that for the black hole discussed in the article the minimum safe distance would be over 9km. For the black hole of much smaller mass I mentioned above you'd need to be millions of km away.
