The Red Cross held its Pre-Labor Day Blood Drive in Salt Lake City, Aug. 29, 2011. According to the Red Cross, in Utah, someone needs blood every eight minutes. To meet the constant demand, the Red Cross strives to collect nearly 400 units of blood every day to serve the 33 hospitals it serves. Hurricane Irene forced the cancellation of nearly 60 American Red Cross blood drives, resulting in a shortfall of more than 2100 units of blood.
