Disinfection & SafetyPregunta 26 de 100
An esthetician opens a new concentrate and estimates the dilution 'by eye' because the measuring cup is missing. What is wrong with this?
a.A disinfectant only performs as EPA-registered when mixed at the exact label dilution, so it must be measured accurately
b.Nothing, as long as the solution looks the same color as usual
c.Nothing, because a stronger mixture is always safer
d.It is acceptable if the implements are left in longer to compensate
Explicación
EPA registration and the stated kill claims apply only at the labeled dilution; too weak fails to kill pathogens and too strong wastes product, damages implements, and increases skin and respiratory irritation. Color is not a measure of concentration, and extending soak time does not correct an incorrect concentration.
