Will it be dangerous to stay in a hotel that can cook, and will there be liquefied gas leakage?

There will be danger, and it is also possible.

Because the hotel's fire protection requirements are strict, if cooking has nothing to do with fire, liquefied gas leakage is likely to occur.

Hotel rooms are generally not allowed to cook, fire exits must be kept unobstructed, safety escape signs should be clear, safety escape maps should be marked behind indoor doors, and gas masks, emergency flashlights and other items must be equipped indoors.
