AThe 3-minute contact time is sufficient for metal surfaces even if the label says 10 minutes
BMetal implements cannot be disinfected with spray disinfectants
CSpray application is never acceptable; immersion is always required
DThe surface was not kept wet for the full manufacturer-required contact time, so disinfection was not achieved
✓ Correct answer: D. The surface was not kept wet for the full manufacturer-required contact time, so disinfection was not achievedEPA-registered disinfectants must remain in full wet contact with the surface for the entire contact time listed on the label; wiping dry before that time is up means the product did not have sufficient time to kill the required pathogens.
