Disinfection & SafetyQuestion 4 of 100
An esthetician places metal implements in an EPA-registered disinfectant. How long should they remain in the solution?
a.Until the next client arrives, regardless of the label
b.For thirty seconds, which is standard for all products
c.For the full contact time stated on the product's label
d.Overnight, because longer is always better for metal
Explanation
EPA registration is granted for a specific contact time, and the disinfectant only performs as claimed when implements stay fully immersed for that entire labeled time. A generic thirty seconds is not valid because contact times differ by product. Waiting for the next client is arbitrary and may be too short. Excessively long soaking can corrode or pit metal and is not what the label directs.
