A manager wants to be sure staff are mixing sanitizer correctly on every shift. What is the most reliable way to confirm concentration?
a.Rely on the experienced closing crew to mix by eye, since they have made the solution for years
b.Judge the strength by how sharp the chlorine smell is over the open bucket
c.Compare the tint of the water against the color it had on the previous shift
d.Use the correct test kit or test strips for that sanitizer type and record the readings
Explanation
The only reliable way to confirm sanitizer concentration is to measure it with the test kit made for that specific sanitizer, chlorine, quat, or iodine, and document the reading. Smell, color, and long experience are not measurements: chlorine odor is sharp both when a solution is correct and when it is far too concentrated, quat and iodine solutions barely change the water's tint, and a practiced pour still drifts as bucket water evaporates. Routine testing and recording is part of active managerial control over warewashing.
