Not from the traditional ondol. That only started to happen when coal briquettes replaced wood for convenience.
The system itself is fine and still in use in modern housing, but now with heated water underfloor pipes.

Not the build, but the fuel used. In the 50's onwards coal briquettes were used for convenience but they had the tendency to burn poorly and produce carbon monoxide.
Traditional wood burning and modern underwater pipe systems are perfectly fine.
