In MMBC guidance, PPE is treated as ideally single-use to prevent cross-contamination. If reuse is ever considered due to supply constraints or emergency needs, it must be governed by an approved decontamination process validated for the specific item, backed by an institutional policy, and accompanied by staff training to ensure proper execution, inspection, and reuse safety. This combination ensures the protective function remains intact and that workers are clear on when and how reuse is allowed.

Why this is the best fit: it acknowledges the priority of safety by defaulting to single-use, while providing a clear framework for limited reuse that requires validated methods, formal policy, and proper training. The other options fall short because they either skip decontamination, discard policies, or rely on visual cleanliness, all of which do not reliably ensure protection.
