设施、清洁与虫害第 316 / 320 题
Which factor does NOT affect how well a chemical sanitizer works?
a.Concentration of the sanitizer
b.The color of the sink basin
c.Water temperature
d.Contact time and the presence of soil
解析
Chemical sanitizers work based on concentration, water temperature, contact time, water hardness and pH, and how clean the surface is; soil on the surface can neutralize the sanitizer. The color of the sink basin has no effect on sanitizing. Managers must control the real variables, especially concentration, temperature, and time, to sanitize effectively.
