In the 1950s the American Red Cross ran mobile blood units that gave people a community-based location at which to donate. These mobile units were very efficient, with a large Red Cross truck staffed by two men arriving at an empty location and setting up for the first donation, which would be taken two hours later. The truck would be loaded with at least ten beds, mattresses, dozens of screens and chairs, waste receptacles, tables, stools, huge refrigerated boxes, canvas bags of ice, coffee urns, orange juice, canteen equipment, hundreds of blood bottles, boxes of sterile supplies, bottles of solution, literature and record forms, oxygen tanks, and sheets. The men would have this unloaded and set up on site in less than an hour.
