Containers used to hold alcohol should be changed how often?

• A. Daily
• B. Weekly
• C. Monthly
• D. Quarterly

Answer: (C)

Maintaining clean, effective disinfection supplies is a key part of infection control. Alcohol should be kept in a properly sealed, clearly labeled container and replaced on a regular schedule to prevent contamination and degradation of the solution and its container. Replacing the container monthly strikes a balance between minimizing microbial buildup and keeping waste reasonable, so the alcohol remains effective and the container’s seal and labeling stay reliable. If you notice cloudiness, a change in smell, leaks, or significant evaporation, replace it sooner. Daily or weekly changes are usually excessive for routine use, while quarterly can allow too much time for contaminants or degraded potency. Monthly replacement is a practical standard that supports safe, consistent disinfection.
