Hospital waste disposal routine. Medical worker washing their hands after placing hospital waste in a colour-coded bin (top left). The worker used protective gloves, disposing of them during the process. Hand-washing reduces the chance of cross-contamination by infectious micro-organisms. The tap is operated by motion sensors, avoiding the contact that might also cause cross-contamination. Photographed in the UK.
