An object can be decontaminated by physical and chemical means?

The statement that an object can be decontaminated by both physical and chemical means is accurate because decontamination can indeed involve multiple methods. Physical decontamination typically includes techniques such as sterilization through heat (e.g., autoclaving), UV light, or filtration, all of which can effectively eliminate or reduce microorganisms on surfaces. On the other hand, chemical decontamination utilizes disinfectants, antiseptics, and other substances that chemically interact with pathogens to neutralize or eliminate them.

The option indicating that only chemical methods are used does not encompass the full range of decontamination techniques. Similarly, the idea that decontamination depends on the object overlooks the established fact that both physical and chemical methods can be employed across various types of objects, depending on the context and contamination levels. Therefore, recognizing that both physical and chemical methods can be employed for decontamination reflects the versatility and effectiveness of these strategies in ensuring safety and hygiene in tattoo practices and other industries.
