Description: Caption:
Inside a kitchen undergoing a scheduled inspection, this state appointed health inspector was about to test the concentration of this kitchen’s quaternary ammonium chloride (QAC) disinfectant. In her right hand was a bottle containing QAC CR test strips, in her left hand, she held two strips. One had been used, and had undergone a color change. The inspector was comparing the strip’s color, to a color indicator chart on the bottle, in order to determine the QAC concentration, which would be in parts/million (ppm).
