When wearing a rucksack, which part can I touch before wearing gloves to help me dress?

Wear a backpack surgical gown. Before putting on gloves, you can touch the outside of the surgical gown to help you get dressed. According to the relevant data, the belt of the split surgical gown will be tied to the back, and the back is regarded as a polluted area, so you can directly put your hand through the belt and finally put on gloves. The order of wearing the surgical gown on the back bag is: first wear the surgical gown, then wear gloves, and finally tie the belt.
