If we boil order just a coffee, I personally in the stainless steel enclosure around the hob around not a problem because this is indeed warm, but not dangerously hot. If you use the plate as a small hot plate when traveling, so with a long operating period, so you should with the fingers as far as possible distance from this metal edge have, the combustion driving is high, to also come to the dial of the heating power, here it prefers to attack at times the metal rim of the hotplate.
Faer an adult human is no problem, so I have not yet looked upon me, kids, I would not leave off, but should anyway avoid hobs.
