True or false: Used disposable needles should be capped before discarding into a sharps container.

The statement is false because used disposable needles should not be capped before being discarded into a sharps container. This practice is primarily to prevent needlestick injuries, which can occur when handling capped needles. In many facilities, the safest method is to immediately place the used needle directly into the sharps container without capping it first.

Capping needles can increase the risk of accidental punctures and can compromise the safety protocols in place for handling potentially hazardous materials. Proper disposal practices, including the direct disposal of uncapped needles into designated sharps containers, are critical components of ensuring safety in laboratory settings, which is why this answer is correct.

Awareness of local regulations and institutional policies is important, as some may further clarify or provide additional safety protocols regarding the disposal of needles, but the general best practice remains consistent across settings.
