Can the doors and windows on the first floor of the hotel lobby be fire-proof and smoke-proof windows?

The doors and windows on the first floor of the lobby are generally fire-proof windows. The function of fire window is lighting, and ventilation and smoke exhaust cannot rely on it.

If it is opened, no one can manually close it in a fire, and the original function of preventing the fire from spreading will be lost, so it cannot be used as a smoke exhaust window. It is suggested to maintain the equipment according to the requirements of safety and fire prevention, so as to avoid a short trip and a long regret.
