Pests & FacilitiesQuestion 141 of 240
A worker mixes a fresh batch of chlorine sanitizer but the test strip reads about 25 ppm. What should they do?
a.Add more sanitizer and retest until it reaches 50 to 100 ppm
b.Use it anyway since it is close
c.Add hot water to strengthen it
d.Skip sanitizing for that shift
Explanation
A reading of 25 ppm is too weak to sanitize, so more chlorine must be added and the solution retested until it falls within 50-100 ppm. Using a weak solution leaves surfaces unsafe, and adding water only dilutes it further. Test strips must confirm the correct concentration before use.
