Isolate the hotel dining car and disinfect it after delivery. Where to disinfect?

There is a special disinfection place at the isolation point.

The delivery man gets up at six every morning. After washing, they put on protective clothing and goggles, went to the restaurant to put boxes of food on the dining car, and then walked to all floors with fruit. Disinfect at the door after the end, and then disinfect the dining car.
