Which option would not be appropriate for disinfecting tools and equipment?

• A. Ultraviolet light
• B. Heat
• C. Autoclave
• D. Chemical disinfectants

Answer: (B)

Disinfection means reducing harmful microbes to safe levels, and the method chosen should reliably do that without harming the tools. Heat alone isn’t universally reliable for this purpose: it can damage heat-sensitive instruments, and without a controlled, high-energy process like steam under pressure, it may not kill all organisms, especially spores. In professional settings, methods like an autoclave (steam under pressure) provide sterilization, while chemical disinfectants and UV light offer practical alternatives for different tools and scenarios. So heat isn’t the best universal option for disinfecting tools and equipment.
