A manager tests the chlorine sanitizer in the third sink and the test strip reads 200 ppm. What should the manager do?
a.Use the 200 ppm solution as it is, since a stronger chlorine mix sanitizes faster and leaves no residue
b.Add more chlorine until the strip reads 300 ppm, then soak the wares in that stronger bath
c.Dilute the solution to bring it back into the 50 to 100 ppm range before sanitizing
d.Skip the strip test on later shifts and mix by the cap measurement printed on the bleach jug
Explanation
At 200 ppm the chlorine concentration is above the effective 50 to 100 ppm range, which can be corrosive, leave residue, and is not necessary for sanitizing. The manager should add water to dilute it back into range and retest. Pushing it to 300 ppm makes an already-overstrong solution worse, and mixing by the cap without a strip is how solutions drift out of range in the first place. Too-strong sanitizer is a real hazard, not extra insurance.
