Position the person to be undressed in the centre of the 350-litre bin bag, which is rolled down at their feet, with the vinyl sheet under the bin bag. If the person is wearing a full-face mask with cartridge, a length of adhesive tape can be applied to the circumference of the cartridge (not on the air inlet). Remove the pair of over-gloves and place them in the bottom of the bin bag. Remove the coverall: • open its zip; • roll it down from the interior to the exterior (“rabbit skinning” method) starting with the head, then the torso, arms and legs; • the entire coverall is rolled down to the feet inside the bin bag. Any contamination will remain trapped inside. A small slit can be cut in the bottom of the coverall legs if it does not pass over the shoes (avoid forcing to avoid disseminating contamination). PERSONNEL UNDRESSING AND MONITORING AT THE ZONE EXIT ACTION TO TAKE ON THE SITE OF THE EVENT Protecting the responders in the exclusion zone and the controlled zone 22 Leave the clean zone by stepping out of the bin bag. Remove your under-gloves: place them in the bin bag. Remove your filtration mask by its elastic straps, keeping it over the bin bag, taking care not to let the cartridge touch your chest. The elastic straps are clean because they were protected by the coverall hood. Removal of the pair of overgloves Roll the coverall down over itself, inside out 350-litre bin bag rolled down around the feet of the person Removal of the pair of gloves, then the filtration mask Only one person at a time enters the exit airlock. The procedure below follows the go-forward principle. For greater efficiency and safety, undressing is carried out in supervised pairs from the same service. The undressing supervisor must remain outside the vinyl sheet square throughout the undressing procedure. This step is normally carried out as a 2-person team. This step can be carried out without assistance. SHEET STEP 2 STEP 1 MEDICAL RESPONSE IN NUCLEAR OR RADIOLOGICAL EMERGENCY 73
