Disposing of used sharps has always been a sticky and costly problem. A hard plastic sharps disposal container works well until it's full. Then it's like at home. No one wants to take out the trash, so you add just one more item and leave the dirty work for someone else. In a healthcare facility, that's when a lot of needlesticks happen. Between 12 and 15 percent of needlestick injuries are related to disposal, according to EpiNet and the Centers for Disease Control and Prevention.
