Discard the liquid high-level disinfectant at the end of
its reuse life (which may be a single use), regardless of
the minimal effective concentration. If additional liquid
high-level disinfectant is added to an AER (or
basin, if manually disinfected), the reuse life should be
determined by the first use/activation of the original
solution (ie, the practice of “topping off” of a liquid
high-level disinfectant pool does not extend its reuse
life). Category
