See image, a sheet was placed over one and Georgie was placed on it.you can. Clearly see the EMT's hand resting on the metal bar. The material stretches to support the person on it. You can. See his arm filling out the material. They then transferred him into a gurney.
Yes, sorry I didn't proof it before smashing reply. The image I posted is what they are using. It's covered in a sheet so they can use it over and over again. You can see George's arm filling out the side of the carrier. It was not a dummy, he was on the transport carrier. If you've ever watched a soccer fag get hurt, that stretcher is similar to the one used here.
