Duration (min/shift) in cleaning and disinfecting tasks by occupation. Center line in each box indicates median, top and bottom edges of the box represents 75-percentile and 25-percentile, error bars indicates 90-percentile and 10-percentile, and the dotted line indicates mean. Medical Appliance Technicians were not observed performing cleaning and disinfecting tasks during data collection; Surgical Technologists, Pharmacist/Pharmacy Technicians, Medical and Clinical Laboratory Techs, and Dental Laboratory Technicians were observed completing fewer than five cleaning and disinfecting tasks; therefore these occupations were not included in the figure.
