How should tools that have come into contact with blood be treated?

When tools have come into contact with blood, they must be treated with a high level of precaution to ensure safety and hygiene. The correct approach is to disinfect and then sterilize these tools. Disinfection is the process that eliminates most pathogenic microorganisms, while sterilization is the process that kills all microorganisms, including spores. This two-step process is necessary because blood can carry infectious agents, and relying solely on washing or wiping may not adequately eliminate all risks.

Disinfecting the tools first ensures that harmful pathogens are rendered inactive before the sterilization process is applied. Following up with sterilization guarantees that any remaining organisms are completely destroyed, making the tools safe for reuse. This practice aligns with health regulations and best practices in the cosmetology field to prevent the spread of infections.

Other options like simply washing with soap and water or wiping with alcohol are not sufficient measures, as they do not assure complete pathogen removal. Disposal of the tools, while appropriate for single-use items, is not a practical solution for reusable tools. Thus, the thorough and systematic approach of disinfecting followed by sterilization is critical for maintaining a safe working environment.
