Which practices are encouraged for safe handling of needles?

Utilizing needle safety devices and disposing of needles in sharps containers is the recommended practice for handling needles safely. This approach minimizes the risk of needle-stick injuries, which can transmit bloodborne pathogens such as HIV, hepatitis B, and hepatitis C. Needle safety devices are designed to prevent exposure by protecting the user before, during, and after the use of a needle, which promotes safety in healthcare settings.

Sharps containers are specifically designed for the disposal of needles and other sharp objects, ensuring that they do not pose a risk to waste management personnel or others who may come into contact with waste. These containers are puncture-proof and labeled, making it clear that they contain hazardous materials.

The other choices do not align with best practices for needle safety. Leaving needles exposed increases the likelihood of accidental punctures. Recapping used needles can also lead to injuries and is generally discouraged unless specifically designed safety mechanisms are utilized. Utilizing any available container for disposal fails to meet safety standards, as it can lead to spills, injuries, and increased risk of exposure. Thus, option C embodies the critical practices necessary for safe needle handling and disposal.
