When handling disinfectants, NEVER _________.

• A. Keep in sealed containers at all times
• B. Sanitize only at the end of the day
• C. Never place them in unmarked containers
• D. Label and date all bottles

Answer: (C)

Disinfectants are hazardous chemicals, so you must always know exactly what you’re handling. Placing a disinfectant in an unmarked container removes the only reliable cue to its identity, concentration, and hazards. That opens the door to mistakes such as using the wrong product, applying an inappropriate dilution, or exposing someone to a chemical with an unexpected hazard. In an emergency, responders also need to know what chemical is involved, and unmarked containers make that information unavailable.

To keep people safe, products should be kept in sealed containers and always clearly labeled with the product name, concentration, hazard warnings, and date. Labeling and dating help ensure you’re using the right product within its shelf life and following proper handling. While good practices also include proper labeling of all bottles and avoiding improper storage, the key safety rule is never place disinfectants in containers without clear identification.
