Which of the following defines 'single-use' items?

The definition of 'single-use' items specifically refers to items that cannot be properly cleaned for reuse. These items are designed to be used a single time and then discarded. This is crucial in settings such as beauty and health services, including lash application, where hygiene and safety are paramount. Single-use items help prevent cross-contamination and ensure that clients are not at risk of infections or other complications that could arise from reusing items that cannot be adequately sanitized.

In contrast, items that can be reused after cleaning are not considered single-use because they are intended to be cleaned and disinfected between uses. Additionally, while some items may be used exclusively in sterile environments, this does not inherently classify them as single-use. Similarly, items that are sterilized after each use are also not single-use, as they can be reused once properly sterilized, thus failing to meet the criteria for being a single-use item.
