Final answer:
In barbering or cosmetology, before performing services, practitioners must sterilize tools using an autoclave or alternative methods such as low-intensity ultraviolet light if an autoclave isn't available. Sterilization ensures the elimination of all microbes, while sanitization is generally used for cleaning surfaces to safe levels.
Step-by-step explanation:
A person who holds a license, certificate, or permit in barbering or cosmetology is required, before performing any service, to clean, disinfect, and sterilize their tools. This is crucial for maintaining hygiene and preventing the spread of infections. An autoclave is a commonly used device for sterilization, which utilizes moist heat to effectively kill all types of microorganisms, including bacteria, viruses, and especially the more resilient endospores. If an autoclave is not available, alternative methods such as low-intensity ultraviolet (UV) light can also be used for this purpose. Ultraviolet light sterilizes equipment by depositing energy in a manner that disrupts the DNA of microorganisms, thereby preventing them from replicating and effectively sterilizing the equipment.
Furthermore, it is important to note that all equipment and surfaces that come in contact with skin should also be sanitized. Sanitization refers to cleaning to a level deemed safe for public health, which may involve the use of very hot water or chemical disinfectants. However, for sterilization, which is the complete eradication of all forms of microbial life, autoclaving or UV light can be used effectively.
