Installing an alcohol-based hand-rub dispenser at the point of care to make hand hygiene easier is best categorized as which type of infection-control measure?

Engineering controls are physical/structural measures (like placing dispensers, sharps containers, or sinks conveniently) that build safety into the environment; placing a dispenser to improve access is an engineering control, while performing hand hygiene itself is a work-practice control.Other options: PPE is worn protection; the dispenser placement is neither a surgical nor a pharmacologic measure.Key exam takeaway: Placing safety devices (dispensers, sharps containers) = engineering controls; the act of hand hygiene is a work-practice control.
