wouldn't a kero cook stove stink like a kero heater? and what about the fumes? kero heaters can kill you. kero is safer to handle than, say, gas.
Kerosene stinks if it is not properly vaporized. For instance, if you put it in an oil lamp (with a wick), that will happen. Or if your stove/oven is not properly maintained or operated.
If properly vaporized, good quality kerosene has no smell.
Fumes: yet, if you spill it, it will smell. But it will not explode and it will burn only with difficulty (you can throw a match in a puddle of kerosene and it will not burn). It will also smell if not properly vaporized (typically not enough pre-heating).
Kero heaters can kill you if you operate them without enough fresh air (carbon monoxide poisoning). This applies to ANY open flame heater (kero, gas, wood, coal, ...).
So, in summary, the worst consequence of poor maintenance or poor operation of a kerosene stove is that it smells. For LPG, it is instant death of the operator and anyone else on board.
Which one do you choose?
