Why must disinfectants be stored away from heat and light?

• A. To prevent moisture loss
• B. To prevent rust
• C. To prevent fragrance change
• D. To maintain effectiveness and safety

Answer: (D)

Keeping disinfectants away from heat and light protects their potency and safety. Heat speeds up chemical reactions that can break down the active ingredients or cause them to evaporate, which lowers their germ-killing effectiveness. Light, especially ultraviolet exposure, can also degrade certain disinfectants over time, potentially creating irritating or hazardous byproducts. Storing them in a cool, dark place helps ensure the product remains effective when used and reduces safety risks. Other storage issues like fragrance changes or rust are less central to this guideline.
