Undressing phase
We recommend that the undressing phase takes place in a dedicated changing room, located immediately upon leaving the COVID area. It involves the following steps: 1] remove the second pair of gloves and replace it with a pair of clean gloves; 2] remove the disposable full body scrubs and dispose it in the appropriate container (the front and sleeves of the dress are contaminated, so open the zipper or untie the laces, move it away from the neck and shoulders, touching only inside the garment , turn the lab coat upside down, fold or roll it up and throw it away); 3] remove the first pair of gloves (the outside of the gloves is potentially contaminated, therefore first remove one glove by grasping and pulling it from the outside, then remove the other glove by inserting a finger into the cuff of the glove and thus remove it, taking care not to touch its external part); 4] remove the glasses and/or the protective visor (their front is potentially contaminated, therefore to remove them, grasping the side sections, and place them in a bag for disinfection); 5] remove the mask: first the surgical mask, and then the FFP2 or FFP3, (the front of the mask is potentially contaminated, therefore after having loosened the rear laces, grasp the front of the mask, move it away from the face and remove it); 6] remove cap and shoes covers if not already removed upon removal of the full body scrubs; 7] remove the second pair of gloves; 8] practice good hand hygiene with soap and water or alcohol. For technical reasons, the undressing phase in the video takes place in the same area where the dressing took place, but we remark the importance of undressing in a separate, dedicated area. Figure 4 shows the path that the operator should follow to avoid contamination of the rooms, starting from the dressing phase until returning to the clean common area.
