When handling disinfectants, NEVER

• A. Place them in unmarked containers
• B. Follow the label instructions
• C. Use gloves when handling
• D. Store in a cool place

Answer: (A)

The key idea is that disinfectants must always be clearly identified and labeled whenever they are stored or used. Putting them in unmarked containers saves no one from harm and creates a dangerous situation where you cannot tell what chemical you’re handling. Without a label, someone might confuse it with another product or attempt to use it at the wrong dilution or for the wrong purpose, leading to chemical burns, fumes, or dangerous reactions if it’s mixed with other cleaners.

That’s why following the label instructions is essential: the label tells you the correct dilution, contact time, ventilation needs, and any specific safety precautions. Wearing gloves protects your skin from irritation or chemical burns, and storing in a cool place helps preserve the disinfectant’s effectiveness and reduces the risk of degradation or hazardous vapors. None of these practices are optional; they’re all part of handling disinfectants safely.
