Can hotels and high-rise residential buildings use fire exits?

This can't be done. What the hotel needs is an evacuation staircase with a width of not less than1.2m. The evacuation staircase for high-rise residential buildings requires a clear width of 1. 1m, which cannot be used together according to the specification, unless the evacuation staircase for residential buildings meets the clear width requirement, and the hotel is equipped with evacuation front room conversion.
